The Samsung Galaxy A8 is Samsung's latest and greatest Android device however, the Galaxy A8 does come with a few problems and one of them lies in the Wi-Fi connectivity of the device.
This tutorial will teach you what to do if your Samsung Galaxy A8 won't connect to Wi-Fi networks. Since this issue stems from a few things this guide is going to include advice for troubleshooting both your Android smartphone and your Wi-Fi network and will begin with the more commonly successful solutions for resolving this problem and will go ahead from there.

The thing is, the problem isn't necessarily with your device (the A8) but, your Network is most likely experiencing connection issues that need fixing.
With this setting enabled you’re probably having more problems than just no Wi-Fi connection, but still check this setting on the phone and make sure that Airplane Mode is NOT on.
Authentication failed error message
Authentication issues are often (not always) a problem with the password. It tries to verify/authenticate the password that you are using to log into your router/network and if the password is wrong then it fails to authenticate and will show an Authentication failed error message. Following the first step in this article and triple checking the password can usually help to resolve authentication failed errors and allow you to get back on track and connected to your network once again. So quadruple check the password one more time just for good measure and make sure that it is 100% correct in every way.
I have seen however where the correct password and Wi-Fi information does not work and the device keeps displaying an Authentication failed error message.
If this is the situation that you find yourself in, then try the following…
Manually turn off the Wi-Fi and mobile data on your device, and then turn ON the airplane mode, while airplane mode is still active turn the Wi-Fi back on and then try to connect to the network again. Once the Wi-Fi connects turn airplane mode off. Don’t forget about the airplane mode though because if it remains on then your phone won’t receive calls or allow mobile data when you want to use it. This process sounds a little strange but this can sometimes solve this annoying authentication failed error message.
Not finding available networks
If the A8 is not locating possible Wi-Fi connections, then make sure the Wi-Fi is actually working. If you have another phone or computer or any device that can see Wi-Fi connections make sure that the other devices can see and connect to it. If you have lots of connections to the Wi-Fi already then disconnect a few of them. Some wireless routers have a limit of how many devices you can connect to it. If the Wi-Fi network itself isn’t working, then restart your router or modem. You shouldn’t need to press the reset button, just pull out the power cord from the router or modem, count to 15 secs, and then plug the power cable back in, wait a few minutes for the device to boot back up then try it again. More on this below.
Connected to Wi-Fi network but no internet
Starting to get tricky… for this issue chances are it’s your router or modem, if you didn’t restart it in the previous step then go ahead and do so. Unplug the power cable count to 15 and plug it back in. If it’s still connecting but not using the internet then power cycle the phone itself, turn it off and then turn it back on.
Connect a different device to the Wi-Fi
The first thing you ought to do is make sure that your Wi-Fi is working properly by connecting another device and verifying whether it's the A8 or your network that is causing the problem.
If it turns out that it’s just your Galaxy A8 that won’t connect to the Wi-Fi, then go ahead with the following solutions for possible ways to help fix the problem.
Turn both your Router and Galaxy A8 OFF
The second thing that you can try, to fix your A8 Wi-Fi connectivity issues, is to turn your A8 and/or your router off and then turn them on again. Read a bit more on what you need to do below as this sometimes resolves the issue. Starting with the network:
Soft reset the network
Performing a soft reset on your Wi-Fi network is the first thing that you try when troubleshooting this issue, especially if the issue suddenly started occurring.
A soft reset of your network is a common solution and can often help fix the internet on your Galaxy A8 and luckily there is no loss of data.
Simply unplug the power cable from your router/modem wait 30 seconds to a minute and then plug the power cord back into the router/modem. It may take a few minutes for the network to start-up again so give it 2-5 minutes to make sure everything was able to boot up as it’s supposed to and then check your Galaxy A8 to see if the internet is working or not.
If it is working, then that's great news! If not, then you might want to check out some more troubleshooting tips below. I am sure that you will be able to resolve the connection issues with one of them.
Soft reset your Galaxy A8
If rebooting your network didn’t help, then try rebooting your A8. Simply select the restart option or choose to turn it off entirely and then boot it up normally. After it reboots then test to see if the internet has started working properly or not.
If not then try performing a soft reset on the device by removing the battery with the device powered on, then wait for a minute, re-insert the battery, and start-up the phone. Now not every Android smartphone has a removable battery so if you have a built-in battery and it is non-removable then you can skip the physical battery pull as maybe your device allows a simulated battery pull instead. You can learn how to do the simulated battery pull below:
How to do a simulated battery pull on a Samsung Galaxy A8?
- Step 1: Make sure that the power is completely off. Make sure that the phone is not plugged into a charger either. Note: if the keys on the bottom of the device are lit then the phone is on, if there aren’t any lights showing or lit up then don’t worry about whether your phone is on or off, simply go ahead to step 2.
- Step 2: Hold the Volume Down button and then the power button and continue to hold these 2 keys for 20 secs (count out loud it could take 15-30 sec).
- Step 3: The phone should power cycle, powering back on to full.
- Step 1: Make sure the power is completely off and that the phone is NOT plugged into a charger.
- Step 2: This time instead of the Volume Down key use the Volume Up key. Hold the Volume Up and the Power key simultaneously for 20 seconds and see if anything pops up on the screen.
- Step 3: Release the Volume Up and Power keys if/when you get a response.
- Step 4: If you get some options then use the volume down key to cycle through your choices. Look for an option to restart or reboot. (don’t do the wipe data/factory reset option… yet… that’s kind of a last resort)
- Step 4: Once selected use the power key to execute.
- Step 5: The A8 should reboot.
Now check your Wi-Fi Connection and see if it is working.
Check the Power Saving Features on the Galaxy A8
Sometimes you may forget that you enabled power saving features on your device. You need to make sure that you haven't set Wi-Fi restrictions on the Galaxy A8 via the power saving mode in Settings > Power saving mode. Check to make sure that you disable any restrictive setting on your connectivity setting.
If you did find restrictions and removed them, recheck the connection between you Galaxy A8 and your wireless internet. Is it fixed? YES! Then great for you. If not continue to the next page for a possible, fix.
Disconnect and remove the network connection from your A8
Before trying this next suggestion, make sure that you know or have access to your networks login information (such as the network password) as you will need to log onto the network again.
If you are not sure what your network's password is or what you would need to use to log back into your network, then you can skip this part of troubleshooting for the moment and then once you have that information available you can move on with this step in troubleshooting. Don’t just skip this step entirely though as it could help to fix the internet on your A8.
How to forget your phone's network?
Access the Settings on your A8 and look for the Wi-Fi option (it's often located under the “Connections” tab within the device Settings). Tap Wi-Fi to open some extra settings and then look for the name of the Wi-Fi network that you are having trouble with. You can simply Tap (or Tap and hold in some cases) on that network which should give you an option to Forget or Forget network. Go ahead and tap on that choice to instruct your phone to forget that network and all of its current settings.
Before you log back into your network it is best that you reboot both your phone and your network's router/modem first. Once everything is back up and running access the Wi-Fi option on your phone again, find the network again, and then try connecting to it once again.
Once your A8 connects to the Wi-Fi network try to use the internet to see if it’s working properly. If you're still facing connectivity issues, then go ahead so you0 can learn more ways to resolve the problem.
Check the Wi-Fi timer
Make sure to switch “OFF” the Wi-Fi timer under your Advanced Wi-Fi Settings on your phone.
To access this feature, open your device's Settings > tap Wi-Fi > tap the Menu key > select Advanced > and under Wi-Fi timer make sure the switch is OFF.
Check the time and date
This is a strange little bug that causes problems but make sure that the time and date on your A8, your modem and wireless router all match the date and time of your ISP (Internet Service Provider).
If you are unsure how to do this, then you may need to contact your ISP just to verify that everything on your network works correctly.
If your applications on your A8 that act as a security application such as an antivirus, a virus scanner, firewall etc. then you should definitely check that application to see if it needs reconfiguring as it might be blocking your phone from accessing the internet properly.
If you can’t seem to find the proper setting to adjust or the proper configuration for your device and network then try, if only temporarily, to uninstall that application from your phone to see if it is the cause of the problem.
If you uninstall it and your A8's internet starts working properly again then you may need to contact the app developer to see if they could recommend or guide you through configuring their apps settings in order for everything to work as it should. It might be as simple as checking or unchecking one of the available security options or features for your device.
Change the IP settings on your Galaxy A8
This isn't necessarily causing the issue but, if you've tried all the previous fixes to no avail, you can also define the way your device connects to the network IP by choosing your router (wireless network) and try changing the IP settings to Static.
Use a Static IP as opposed to the DHCP
This process is a little different depending on what version of Android your phone is running but typically you can open your device's Settings > tap Wi-Fi > press the Menu key > tap and hold your finger down on the desired network which you want to set up a static IP address on (aka the network you're having problems with) until some more option pops up > tap on Modify network config > make sure to select the Show advanced options setting > under IP settings make sure to select Static and not DHCP > complete the fields that pop up using your network's current configuration > then click Save.
Now check to see if you've finally resolved the connectivity issue on your A8. If not, you can continue to the next fix in the series.
Check your browser and homepage
Make sure that you verify that your internet is in fact malfunctioning as opposed to an issue with your web browser or even worse a problematic home page.
Open your web browser and in the address bar (where it shows what web page you are on) type in the URL of a website that you KNOW is working. I suggest typing in https://www.google.com/ or simply google.com (don’t forget to press the Enter or Search key after you have finished typing the URL to load the page).
If the webpage ends up loading successfully and you can do a search through the Google search engine, then that is a great sign as it indicates that there is not a problem with your phone or its internet but it’s an issue with the web page your phone is trying to load by default.
Changing your A8's default home page should fix this little hiccup and it will no longer seem like the internet is malfunctioning on your cell phone.
Enable Keep Wi-Fi on during sleep on the Samsung Galaxy A8
In Wi-Fi > Settings > Advanced, make sure to set Keep Wi-Fi on during sleep to Always and check/enable Always allow scanning. Now, restart your device and check your connection to see if it works. If this doesn't apply to you or if it didn't work, then move to the next fix.
Check your Wireless router settings
This fix involves modifying your router settings by ensuring that the MAC filtering on your router is not blocking your device by accident or you can make sure it’s off or that you have the A8 MAC address in the whitelist (you can find the A8 MAC address listed in Wi-Fi > Settings > Advanced).
There is still one more tip that can help you if all of earlier ones did not help solve the Galaxy A8 Wi-Fi connectivity issue.
Disable Smart network switch on the Samsung Galaxy A8
This may come as a surprise but the culprit might very well be your mobile network. If you have both Wi-Fi and Mobile Data enabled at the same time, then turn off the mobile data connection. Some persons experience a drop in the connection to the Wi-Fi which is sometimes caused by the device trying to decide which connection is best. If you want to keep your mobile data connected, then you ought to uncheck the box next to “Smart network switch”.
Try updating your Router's firmware
You could also try updating the firmware on your router. I highly doubt that this is necessary but it is still worth a shot. If you don't know how to get access to your router settings to do this, then you may need to contact your service provider/ router provider for details about gaining access to the setup page.
These are all the simple steps that you can take to fix your connection issues. There is a short recap below for reference. If you're still having connection issues, then you can take a look at the advanced section (which I saved for last) below the summary.
What have we learnt today? How to troubleshoot Wi-Fi connection issues on a Samsung Galaxy A8
- Soft reset the network – unplug the power cord from your router/modem for a minute or two and then plug it back in. Then wait for the network to fully reboot.
- Soft reset the smartphone – power your A8 off and on and if possible try to pull the battery.
- Check the home page – make sure to verify that your internet is in fact malfunctioning by attempting to visit another website through your web browser.
- Check your applications – if you recently downloaded, updated or changed an app on your android then check to make sure that app is not causing mischief.
- Review any Security applications – verify that any security applications are not causing any problems as well.
- Check the Wi-Fi timer – make sure to switch the Wi-Fi timer on your Android off.
- Forget the network – try to forget the Wi-Fi network and then log into it again as if logging into it for the first time.
- Check the time and date – make sure that the time and date of your phone, network devices and ISP (Internet Service Provider) all match.
- Use a Static IP instead of DHCP – setup a static IP as opposed to using the default DHCP configuration.
- Download a Wi-Fi App – Since the Wi-Fi internet on your phone is not functioning properly you will need to use your phones mobile data or you will need to do this through a PC but consider installing an app intended to help fix Wi-Fi issues such as this one.
- Troubleshoot your Wi-Fi network – if the advice above proves ineffective then look into accessing your networks settings to make sure that everything works properly.
- Troubleshooting the A8 itself – even though this particular Wi-Fi issue is usually the result of a problem on the Wi-Fi network as opposed to an issue with the phone if all other troubleshooting had been unsuccessful then you may need to look into troubleshooting the phone itself.
Have you tried everything that you can think of to get the Wi-Fi on your Samsung Galaxy A8 to work properly but it just won’t work? You’re not alone! This guide will go over some tips and tricks that you can try to get your Wi-Fi connected and working correctly once again.
Before we begin
Before we start troubleshooting the Wi-Fi connection on your cell phone or wireless network, I want to take a second to state that this guide is a reference for fixing advanced Wi-Fi problems that can occur on your A8.
This guide is also intended to give more support when ALL standard troubleshooting tips are exhausted and there are few options left to try when troubleshooting the A8 itself.
If you have not read the above section on How to fix the Wi-Fi on a Samsung Galaxy A8 then go ahead and read that section of the article FIRST and follow every suggestion listed as it covers many tips and tricks that can get you connected to a wireless network. If you have read and done all the steps in that section of the guide including a factory data reset and have also tried to set up a static IP address, then please continue reading for some extra suggestions.
Advanced Wi-Fi troubleshooting for the Samsung Galaxy A8
So you have tried all the basic approaches to try troubleshooting your A8 and the Wi-Fi still isn’t connecting properly. Here are a few strange Wi-Fi issues that are a real pain to try to fix when they happen to any device.
I upgraded my A8 and now my Wi-Fi isn’t working
This seems like an issue that can happen on a A8. This is usually a software conflict on the phone itself but if you have already tried standard troubleshooting and this is the corner that you're in then keep reading for a fix.
When trying to connect my A8 to Wi-Fi it keeps saying “not in range”
This issue can happen after upgrading as well, and is one of the most confusing Wi-Fi issues to have. You can hold your device right next to the wireless modem or router and get no signal. Sometimes you can even set up a Wi-Fi connection when you're right next to your router but as soon as you create a little distance between your device and the wireless source your A8 shows an “Out of range” or “Not in range” or “Not in range, remembered” error message. A very annoying issue that is difficult to fix but this article has some suggestions for this issue as well.
SSID or Network Name(s) don’t appear when scanning network on my A8
You scan for networks but the network you want to connect to won’t display, and of course there is no option to connect to it. There are a few things that can cause this problem, including hardware issues on the phone itself (like a damaged or malfunctioning antenna) or the wireless network might be hidden.
Wi-Fi disappears after trying to connect to it.
Your phone scans for networks, shows the network that you want to connect to, you click that network to set up the connection and lo and behold the network vanishes and of course the phone doesn’t establish a connection.
These are just a few of the issues that the standard troubleshooting in the article mentioned above won't necessarily fix.
This is because many of the issues described above are the result of a problem with the wireless network and not a problem with your smartphone. The wireless network might just need a few settings changed in order for everything to work properly.
A8 connects to some wireless networks but not others
If the Wi-Fi on your A8 seems to work with some wireless networks and doesn’t seem to work on others such as if your Wi-Fi works when using a public Wi-Fi or when using the Wi-Fi at your work but the phone doesn’t want to connect when trying to use the wireless network at your home, then these issues are more likely an issue with the network itself and not your cell phone. In which case you’re in the right place as the suggestions in this article can help you find the cause and better yet the solution.
A8 won’t connect to Wi-Fi but other devices are working just fine
If you’re trying to connect to your home Wi-Fi and cannot set up a connection but other devices like your laptop, or even other cell phones seem to work fine then this can still be the result of a network issue and does not necessarily mean it’s an issue with the device itself. So keep reading as this article can address this problem as well.
The following troubleshooting tips are suggestions that can and may get your Wi-Fi working properly. The following settings will vary depending on your particular wireless network or equipment and the best way to change such settings is to refer to your modem/router's owner’s manual or by contacting the manufacture of the wireless modem/router directly or by contacting your ISP (Internet Service Provider) for guidance.
It is recommending that you write any original setting(s) that you end up changing when troubleshooting your network so that you can revert back to those setting if a suggestion turns out ineffective or the problem persists. I am not responsible nor accountable for any issues that might occur when manually adjusting these settings.
If problems arise you can always reset the modem or router back to default so there is little to no chance of causing anything permanent, but I just want to make it clear that you should pay attention to the settings that you change so that you can go back to the original settings should you want or need to.
Troubleshooting your Wi-Fi connection
OK now for what you came here for, the real Wi-Fi troubleshooting! Since you have already completed the suggestions in the Wi-Fi troubleshooting guide mentioned above most of what you can do to your A8 to get the Wi-Fi working again is done. This means that the solution is phone related but network specific. So we are going to need to use your modem or router to adjust some settings.
The process to get access to the settings on a modem or router is typically straightforward but could vary from device to device. You might have to do a quick Google Search for your specific router and how to configure it. For example, if the network that you are trying to connect to uses a Linksys router (a pretty common brand of router) then you can do a search for “How to configure a Linksys Router” or “How to use a Linksys router” etc. You shouldn’t have too much trouble locating the method to access your wireless network settings. If you do have trouble, then contact your ISP (Internet Service Provider) and they can tell you how.
Note: Before accessing your router or modem if you have not already soft reset your device then make sure to do that first. Simply remove the power cord from the wireless router/modem wait for at least 30 seconds (1-2 minutes couldn’t hurt) and then reinserted the power back into the device. Wait for your wireless router to power back on (which can take a few minutes), and then try to connect your cell phone to the network again to see if this easy trick fixes it. If you have already done this or it doesn’t work, then go ahead with the troubleshooting mentioned below.
Network settings to look for
Once you gain access to your network and can get access to and configure its settings then here is a list of things to try adjusting. Note: some routers may not have these exact settings or you might have to do some probing to find the setting that you need to change when troubleshooting.
If your network is a secured network than quadruple check the password to make sure that you are typing to proper password into your phone (which I’m hoping, you had done already) and for good measure try removing the password to see if you can connect to the network when its open and not password protected.
If you can connect then reenter the passwords on your router and phone and see if it helped. If you still cannot connect then re-setup the password anyways as you don’t want to have an unsecured network when you can help it, and some other network settings might be more promising.
MAC address filtering
Check your MAC address filtering and try switching it off or to disabled. With the MAC address filtering turned on your network is performing an additional security feature, which is great as more checks can keep your network more secure, but, set up this configuration properly or it can cause these types of problems.
If your networks Wireless MAC filter is the culprit it might be why some of your wireless devices work on the network and your cell phone doesn’t. The working devices might have their MAC addresses listed as allowed connections but your phone is one of the allowed devices.
Your router may also have a list of addresses prevented from accessing or connecting to the wireless network. If you see an option that says something like, "Prevent listed computers from accessing the wireless network" and find your cell phone's MAC address under that setting then remove it from that list and enjoy your working Wi-Fi.
If you check your MAC address filtering and don’t see a list of prevented devices and or have tried turning off or disabling the Wireless MAC filter feature, have rebooting your phone, and if necessary rebooted the router and have tried connecting your cell phone to the wireless network again and it’s still not working then keep reading for some other settings to check.
Change the Channel
If you live in an apartment complex, school dorm or have close neighbors then you have probably noticed multiple SSID (Wireless Networks) when scanning for Wi-Fi networks on your cell phone. If so, then those other wireless networks might be running on the same channel as your wireless network and causing some interference.
If you are having issues involving a weak Wi-Fi signal, such as “Out of Range” or “Not in Range” error messages or your cell phone disconnects from your Wi-Fi, then manually setting or changing the channel(s) on which your router broadcasts your Wi-Fi signal can help boost the signal and create a stronger connection.
Routers sold in the US have the option to choose from channels 1 through 11. Channel 6 is a common default channel on many US routers but channels 1, 6, and 11 are also commonly used channels as these channels have little overlap with one another. For the best signal and least interference a good general practice is to choose a channel as far away from everybody else as you can.
If the channel setting on your router is Automatic (which is common) then manually adjust the channel to the lowest channel (channel 1) and start working your way up (to channel 11) from there, making sure to test your phone's Wi-Fi functionality for a few minutes each time you adjusting the channel and save your router's settings.
If you live outside of the United States, then the channels for your router or modem may vary but the general principle is going to stay the same.
You might have to change the channel on your router a few times before finding the best frequency band for your specific cell phone or place but this is also another setting to try adjusting and can help fix many stubborn Wi-Fi issues.
Security Settings and Protocols – WEP vs. WPA
If your router or modem is still using a WEP (Wired Equivalent Privacy) encryption instead of the more secure WPA (Wi-Fi Protected Access) or the even better WPA2 (Wi-Fi Protected Access II) encryption, then not only do I recommend that you change your wireless router/modem from WEP to WPA1 or WPA2 to try to fix the Wi-Fi connection with your phone but I recommend you change it to better secure your wireless network.
WEP is an older security protocol that isn’t only outdated but not a very secure method of encryption, so changing this setting to a more current encryption type like the WPA2 encryption won't affect your connection one way or the other.
Most current wireless routers have the ability to use multiple types of Wi-Fi technologies to improve your wireless network's speed, range, and connectivity. Some phones however, might have difficulty connecting to or staying connected to one of these technology types, depending on how you configured your router; so testing the different Network Modes that your wireless router has to offer might also help you fix your cell phone's Wi-Fi connection.
These Network Modes are often listed under the router's Wireless settings and can give many Network Modes to choose from including Mixed, Wireless-B/G Only, Wireless-B Only, Wireless-G Only, Wireless-N Only, Disabled, etc.
Mixed is often the default mode for many wireless routers and is generally the best Network Mode for wireless networks as it should allow the router to automatically communicate with many devices regardless of what type of network adapter or wireless standard the device uses to connect to a wireless network.
Try modifying these settings on your router to make sure that the Network Mode isn’t the cause of your Wi-Fi problem. Make sure to “Save” the changes you make on your router after each adjustment, and to test your cell phone's Wi-Fi connection when you change to a different Network Mode.
I suggest that you start by changing your router's Network Mode to use Wireless-B/G Only (802.11 B & G mode only) as I have seen this Network Mode solve some Wi-Fi issues, even though the Wireless-N technology is backwards-compatible I have heard of it causing issues with some types of smartphones and their Wi-Fi connection, especially when it involves connecting to a hidden wireless network.
Hidden wireless networks are just that, hidden. If you are trying to connect your smartphone to a hidden Wi-Fi, then that hidden wireless networks is not going to be one of the options shown when scanning for available networks. This means that you won’t be able to simply click on the SSID (name of your network), type in the password and be good to go.
If you have a hidden network, then that network is not going to show at all on your cell phone because to your cell phone it doesn’t exist. It is still possible to connect to a hidden Wi-Fi on your smartphone though you just need to type in the hidden networks information manually.
To manually connect to a hidden Wi-Fi, you can open your phone's list of available networks, scroll down to “Add network” or “Add Wi-Fi network” and then manually enter the information for your hidden wireless network and be good to go.
Just make sure to enter the network's information exactly like its setup on the wireless router/modem. Every piece of information must match. The password and SSID are both case-sensitive so if your phone capitalizes the first letter of the network name but the networks SSID starts with a lower case letter then chances are the phone won't connect properly. So if your phone won’t connect to a hidden Wi-Fi then double-check the information entered as one simple typo or upper/lower case letter causes login problems.
As far as hidden networks go however… many people, including myself, recommend that the average person should leave their SSID broadcast set to On as hiding your network doesn’t always mean added security, and a hidden network can cause issues with your network connections and be a real headache later on down the road. In some cases, even after correctly entering all the hidden networks information into the phone some devices can still have problems connecting and working properly.
One of the best ways to keep your network working properly while at the same time remaining secure is to simply use the best encryption method available (WPA/WPA2) and of course to set up and use a strong password.
Clean up all the settings
If you have tried adjusting the settings mentioned above and STILL cannot set up a connection to your wireless network or get internet access on your A8, then there might be a setting on the device that you missed and as a last resort I recommend that you do a hard reset on the router/modem itself which will revert all of its settings back to factory default.
The method(s) used to reset a router is going to differ from device to device but most routers have a real reset button (usually on the back or rear of the device) which you can press down with a paperclip or pen tip for 30 seconds which will force it to reset, reboot, and be back to factory default and its original settings.
If you cannot find a reset button on your device, which is extremely uncommon, then do an online search for your specific brand and model of router and you shouldn’t have too much trouble locating its hard reset instructions.
Some routers (especially Linksys routers) also come with the option to “Restore Factory Defaults” under their Menu settings which will work as well.
Wi-Fi issue with the A8 itself
If you have tried these steps and your cell phone still refuses to set up a data connection on any wireless network then the issue lies on the phone itself, most likely a malfunctioning or damaged piece of hardware and if you need Wi-Fi on your cell phone then you are going to have to look into these other options which include replacing or repairing the unit.
If you have tried troubleshooting your phone and have made no progress in getting it to connect or stay connected to your wireless network properly then the fault may not lay with the phone but could be an issue with the wireless network itself. To help rule out your wireless network as the culprit you should…
- Check your network's password – making sure that it matches the password you are entering in your cell phone.
- Try different wireless channels – try changing the channels of your router under its wireless settings.
- Use updated encryption methods – check to make sure that your router is using the best settings to use a stronger security encryption such as WPA or WPA2 as opposed to an older standard such as WEP encryption.
- Try changing the network mode(s) – changing from the usual “Mixed” setting to other options available such as the “Wireless-B/G Only” setting.
- Reset router/modem – as a last resort you can set the router back to factory defaults to make sure that it isn’t a bad setting on the router that’s causing these Wi-Fi problems with your cell phone.
- Verify it's a hardware issue – after exhausting all the troubleshooting steps listed above, troubleshooting both the phones software and network settings, if the phone is still having issues connecting or staying connected to a wireless network then it’s likely a hardware issue on the phone itself and the phone will need to visit the repair shop for repair or replacement.
