Varying contributing factors affect the Galaxy S5’s ability to connect to WiFi networks. Firewalls settings & Antivirus applications block the S5 from connecting to the internet. Furthermore, system settings also play a role in connecting the Galaxy S5 to WiFi networks.
Even more, some users report Galaxy S5 Slow WiFi connection problems. Whatever the case, we discuss possible causes for Wifi connectivity issues on the S5. Secondly, we talk about options available to connect your S5 to the internet. And, finally, we present a roundup of all the choices available to you.
How to Connect Samsung Galaxy S5 to WiFi or Internet?
Firstly, how do I use Wi-Fi on my Samsung Galaxy S5? Wi-Fi is a wireless connectivity feature. Wi-Fi allows you to connect Wi-Fi-enabled devices to the internet. Open the Quick Panel/Access by swiping two fingers (held slightly apart) from the top of the screen to the bottom.
Secondly, touch the Wi-Fi icon to turn Wi-Fi on or off. When Wi-Fi is on, the device scans for and automatically connects to previous access points. Can't access the pull-down menu? Here's another way to connect the Galaxy S5 to the internet.
From the Home screen, touch Apps. Now, tap Settings. Then, tap WiFi. Under Wi-Fi Networks, choose the network to which you wish to connect. Additionally, enter the wireless password if necessary. Lastly, select Connect. Let's talk about connectivity issues on the Galaxy S5.
Why Won't My Galaxy S5 Connect to Wi-Fi or Internet?
First, realize that the problem isn’t necessarily the Samsung Galaxy S5. Perhaps your Internet Service Provider (ISP) has connection problems at the time. Give them a call to verify that their service is up.
Furthermore, things such as Airplane Mode, authentication errors, software issues and, even hardware problems affect the Galaxy S5 WiFi connectivity. Once you know that the problem is not with your ISP, we can look at more causes & solutions.
We begin with Airplane Mode and move from there into authentication errors. After, we talk about why the Galaxy S5 can't find Wifi networks. Also, we discuss when the Galaxy S5 connects to WiFi but has no access to the Internet. And so on, and so forth.
Samsung Galaxy S5 Won't Connect to WiFi - Airplane Mode
With Airplane Mode enabled the Galaxy S5 experiences more than WiFi problems. Airplane Mode also turns off Mobile Data. Blocks incoming calls and prevents outgoing calls. This mode also affects texting. It prevents any and all connections between your Galaxy S5 and data connections. Let's see how to enable & disable Airplane Mode on the Galaxy S5.
Samsung Galaxy S5 Airplane Mode
Activate the Samsung Galaxy S5 airplane mode from the home screen. Touch Apps and head into the Settings. Locate Airplane mode and Touch the switch to turn it on or off. Also, you can access airplane mode via the quick access toolbar.

To access the Quick Panel, use two fingers to swipe down from the top of the screen. Touch the Airplane mode icon. It looks like an airplane. Don't see the image? Try tapping more settings in the upper right-hand corner. When the feature is on the icon appears green. If the Flight Mode icon is green, tap the switch to turn it off. Check that your connection works.
Galaxy S5 WiFi Problems: Authentication Failed Error Message
Next, on the list of Samsung Galaxy S5 WiFi problems, is the authentication failed error message. The S5 attempts to verify passwords used to login into your WiFi connection. A wrong password fails validation and, as a result, the Authentication Failed error message displays. Triple checking the password usually helps to resolve authentication failed errors. Extra checks allow you to connect to your network if the password is the issue.
So, quadruple check the password just for good measure and make sure that it is 100% correct in every way. However, the right password and Wi-Fi information sometimes don't work. Furthermore, the Galaxy S5 persistently displays an Authentication failed error message. If this is your situation try the following:
Manually turn off the Wi-Fi and mobile data on your Samsung Galaxy S5. Now, activate airplane mode on the Galaxy S5. With airplane mode active, turn the Wi-Fi back on and then try to connect to the network again. With the Wi-Fi connected turn airplane mode off. Don’t forget about the airplane mode. If it remains on, your Galaxy S5 won’t receive calls or allow mobile data. The process sounds a little strange, but this method sometimes solves the authentication failed error message on your Galaxy S5.
Galaxy S5 WiFi Issues: Not Finding Available Networks
If the S5 is not locating possible Wi-Fi connections, then make sure the Wi-Fi is working. Use another device to check the Wi-Fi connections. Ensure that the other devices see and connect to networks. If you have lots of connections to the Wi-Fi already, then disconnect a few of them. Why?
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. Now, plug the power cable back in, wait a few minutes for the device to reboot then try it again. Does your Galaxy S5 connect to the internet now? Does the Galaxy S5 connect but fails to access the internet? If so, read below for more information.
Galaxy S5 Connected to Wi-Fi network but no Internet
Continuing with regular Galaxy S5 WiFi Issues, the chances are that it’s your router or modem causing the connection issue. Did you restart your router in the previous step? If not, do so now. If it’s still connecting but not using the internet, then power cycle the Samsung Galaxy S5. Turn off your Galaxy S5 and then turn it back on.
Connect A Different Device to the Wi-Fi
Make sure that your Wi-Fi works correctly. Connect another device and verify internet functionality. Is it your Galaxy S5 that won’t connect to the Wi-Fi? Go ahead with the following solutions for possible ways to help fix the problem.
Turn both your Router and Galaxy S5 OFF
The second thing to fix your S5 Wi-Fi connectivity issues is to turn your Galaxy S5 and your router off. After which, 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 so if the problem suddenly started. A soft reset of your router is a standard solution and can often fix the internet on your Galaxy S5. Luckily, there is no loss of data.
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 takes a few minutes for the network to start-up again. Give it 2-5 minutes to make sure everything boots up as per usual. Check your Galaxy S5 to see if the internet works correctly or not.

Check the Galaxy S5 Time and Date Settings
Incorrect time and date cause WiFi problems. Make sure that the time and date all match the date and time of your ISP. Contact your ISP to verify that everything on your network works correctly.
Galaxy S5 Security Applications
The use of security apps like antivirus, virus scanners, firewalls, etc. sometimes blocks internet connections. Check the application's configuration. Ensure that there is not an internet block in place. Can’t find the appropriate setting for your Galaxy S5? Temporarily uninstall that application from your S5 to see if it is the cause of the problem.
If you uninstall it, and your S5's internet works smoothly, contact the app developer for help configuring the app. Simple things such as checking or unchecking one of the available security options for your S5 resolves internet issues.
Change the Galaxy S5 IP settings
The IP settings don't necessarily cause Galaxy S5 Wifi issues. Tried all the previous fixes to no avail? Defining the way your device connects to the network IP is another fix to try. Do this by choosing your router (wireless network) and changing the IP settings to Static.
Use a Static IP instead of DHCP
This process depends on what version of Android your S6 uses. 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.
More options pop 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.

If not, you can continue to the next fix in the series.
Check your Browser and Homepage
Make sure to verify that your internet is in fact malfunctioning as opposed to an issue with your web browser. Open your web browser and, in the address bar, type in the URL of a website that you KNOW works. I suggest typing in https://www.google.com/ or simply google.com. Don’t forget to press the Enter or the Search key to load the page).
Does the web page load successfully? Are you able to perform a search on the Google search engine? Success indicates that there is not a problem with your Galaxy S5. Nor is it an issue with the internet. More than likely, it is a web page level error.
Moreover, changing your S5's default home page fixes this little hiccup. Still unable to connect to the internet on the Galaxy S5? No worries, there are other troubleshooting tips for you to try.
Enable Keep Wifi on during Sleep on the Samsung Galaxy S5
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 Wireless Router Settings
Modify your router settings. Ensure that the MAC filtering on your router is not blocking your Galaxy S5 by accident. Make sure it’s off or that you have the S5 MAC address in the whitelist. Find the S5 MAC address listed in Wi-Fi > Settings > Advanced. See more tips ahead to help if you still have Galaxy S5 Wi-Fi connectivity issue.
Enable or Disable Galaxy S5 Auto Network Switch Setting
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 link with the Wi-Fi. Often caused by the Galaxy S5 trying to decide which connection is best. Want to keep your WiFi connected? Then you ought to uncheck the box next to “Smart Network Switch”.
- From a Home screen, navigate to Apps > Settings > Wi-Fi.
- Tap the Menu icon (located in the upper-right).
- Tap Advanced.
- Tap Smart network switch to enable or disable. ...
- If presented with the "Smart network switch" prompt, tap OK to continue.

Samsung Galaxy S5: Advanced Wi-Fi Troubleshooting
So, tried all the basic approaches to try troubleshooting your S5's Wi-Fi malfunction? Here are a few strange Wi-Fi issues that occur on the Samsung Galaxy S5. Also, be sure to check out the tips to fix them afterward.
I Updated My Galaxy S5 & My Wi-Fi Isn’t Working
Updates fix as well as cause issues on the Galaxy S5. Usually, a software conflict occurs on the Galaxy S5. If you tried standard troubleshooting, read on for more tips.
When Trying to Connect My Galaxy S5 to Wi-Fi, it says “not in range.”
This issue occurs after an update as well. It can be 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 set up a Wi-Fi connection when you're right next to your router. However, some distance between the S5 & wireless source results in “Out of range”,“Not in range” or “Not in range, remembered”. A very annoying issue that's hard 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 the S5
Do you scan for networks but the network you want to connect to won’t display? Of course, there is no option to connect to it. There are a few things that cause this wifi problem. These things include hardware issues on the Galaxy S5. Things such as a damaged or malfunctioning antenna or hidden wireless networks.
Wi-Fi Disappears after trying to Connect
Your Galaxy S5 scans for networks. Shows the network connection that you want to connect to; you click that network to set up the connection and lo and behold the connection vanishes. And, of course, the Galaxy S5 doesn’t establish a connection.
Galaxy S5 Connects to some Wireless Networks but not others
Does the Galaxy S5 work with other WiFi networks? However, there is the one network that won't connect? Like the connection at work, public or at a school? In this case, the issue is with the WiFi connection and not your Galaxy S5.
S5 won’t Connect to Wi-Fi, but other devices work fine
Trying to connect to your home Wi-Fi and cannot set up a connection? Also, do other devices like your computers and smartphones work fine? This problem is a result of a network issue. Keep reading this article. We address this issue as well.
These are just a few of the issues that the standard troubleshooting in the article mentioned above won't necessarily fix. Many of the described items are the result of a wireless network problem and not the Galaxy S5 smartphone. The wireless network just needs a few settings changed for everything to work correctly. Additional information exists below for your perusal.
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. The best way to change such settings is to refer to your modem/router's owner’s manual. Furthermore, contact the manufacturer of the wireless modem/router directly or your ISP (Internet Service Provider) for guidance.
Write down any original setting(s) that you end up changing when troubleshooting your network. Noting down settings allow you to revert to those settings if a suggestion turns out ineffective. I am not responsible nor accountable for any issues that might occur when manually adjusting these settings.
You can always reset the modem or router back to default. There is little to no chance of causing any permanent damage. However, I just want to make it clear that you should pay attention to the settings that you change.
Troubleshooting Wi-Fi Connection
OK, now for what you came here for, the real Wi-Fi troubleshooting! Since you already completed the suggestions in the Wi-Fi troubleshooting guide above, you completed most of what you can do to your S5 to get the Wi-Fi working again. The solution is not phone related but network specific. So, we need to use your modem or router to adjust some settings.
The process to access the settings on a modem or router is typically straightforward. However, it could vary from device to device. You might have to do a quick Google Search for your particular router and how to configure it.
For example, do you use a Linksys router? In that case, you can do a search for “How to set up a Linksys Router”. You shouldn’t have too much trouble locating the method to get access to your wireless network settings. If you do have trouble, then contact your ISP, and they can guide you.
A Word of Advice
Before accessing your router or modem, perform a soft reset. Firstly, remove the power cord from the wireless router/modem. Secondly, wait for at least 30 seconds (1-2 minutes won't t hurt) and then reinsert the source of energy.
Wait for your wireless router to power back on (which can take a few moments). Now, try to connect your Galaxy S5 to the network to see if this easy trick fixes the connectivity issues. If you have already done this, or it doesn’t work, then go ahead with the troubleshooting mentioned below.
Quadruple check the password. Make sure that you type the correct password into your Galaxy S5. Also, for good measure, try removing the WiFI password. I.E. Open the network. Try to connect in this way. Can you connect? If yes, reenter the passwords on your router and Galaxy S5 and see if it helped.
If you still cannot connect then re-setup the password. You don’t want to have an unsecured network when you can help it. Also, some other network settings might be more promising. Next, try modifying the MAC Address settings.
MAC Address Filtering
Check your MAC address filtering and try switching it off. With the MAC address filtering turned on your network allows or blocks only a particular range of MAC Addresses. However, MAC address filtering isn't always a great feature. An incorrect set up this configuration causes these types of connectivity problems.
Was the Wireless MAC filter the culprit? Yes? No? If yes, glad that you solved the problem. If no, read for a bit more information on the issue.
Your router may also have a list of addresses prevented from accessing or connecting to the wireless network. Do you see an option that says "Prevent listed computers from accessing the wireless network"? If so, find Galaxy S5's MAC address under that setting and remove it.
Have you checked your MAC address filtering and don’t see a list of prevented devices? Have you tried turning off or disabling the Wireless MAC filter feature? Rebooted your phone, and, if necessary, rebooted the router? Finally, have you tried connecting your Galaxy S5 to the wireless network again? It's still not working!! No worries, keep reading for some other settings to check.
Change the Channel
Do you live in an apartment complex, school dorm or have close neighbors? The chances are that you notice multiple SSID (Wireless Networks) when scanning for Wi-Fi networks on your Galaxy S5. If so, those wireless networks might run on the same channel as yours and cause interference.
Issues involving weak Wi-Fi signals, such as “Out of Range” or “Not in Range” messages typically occur in these instances. Manually setting the channel on which your router broadcasts helps boost the signal. As a result, it also creates a stronger connection. Moreover, you can purchase a WiFi Extender for added functionality.
Routers sold in the US have the option to choose from channels 1 through 11. Channel 6 is the universal default channel on many US routers. However, channels 1 and 11 are also standard channels as these channels have little overlap with one another. A good general practice is to choose a channel as far away from everybody else as you can.
Set Channel Manually
Firstly, consult your router manual to learn to adjust the channel setting. More than likely, the default is automatic. Manually set the channel to the lowest channel (channel 1). Continue to work your way up to channel 11 from there. Be sure to test your Galaxy S5's Wi-Fi functionality for a few minutes each time you adjust the channel. Remember to save your router's settings.
If you live outside of the United States, the channels for your router or modem may vary. However, the general principle remains the same. Change the channel a few times. However, this is just another setting to adjust to help fix stubborn Wi-Fi issues. You can always skip this step and move to the next.
Verify Security Settings and Protocols – WEP vs. WPA
Does your router or modem use a Wired Equivalent Privacy encryption instead of WPA (Wi-Fi Protected Access)? Or the Wi-Fi Protected Access II encryption? I recommend that you change your wireless router/modem from WEP to WPA1 or WPA2. Both to try to fix the Wi-Fi connection with your Galaxy S5 and to secure your wireless network.
WEP is an old security protocol. WEP is no longer a secure method of encryption. So, changing to a current encryption type like the WPA2 encryption won't affect your connection one way or the other.
Most current wireless routers use multiple types of Wi-Fi technologies to improve your wireless network's speed, range, and connectivity. The Galaxy S5, however, might have difficulty connecting to or staying connected to one of these technology types. Testing the different Network Modes might also help you fix your Samsung Galaxy S5 Wi-Fi connection. Find these Network Modes listed under the router's Wireless settings. They 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. Mixed mode should allow the router to communicate automatically with many devices. Regardless of what type of network adapter or wireless standard the device uses to connect to a wireless network.
Adjust these settings to ensure 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. Also, test your Galaxy S5's Wi-Fi connection when you switch 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). I have seen this Network Mode solve some Wi-Fi issues. The Wireless-N technology is backwards-compatible. However, it causes issues with some types of smartphones.
Connect Samsung Galaxy S5 Hidden Wi-Fi Network
Hidden wireless networks are just that, hidden. You won’t be able to click on the SSID (name of your network), type in the password and connect. You have to input all the information.
To manually connect to a hidden Wi-Fi, open your Galaxy S5's list of available networks. Scroll down to “Add network”. Some have “Add Wi-Fi network.” Additionally, enter the information for your hidden wireless network and click connect.
Just make sure to type in the network's information exactly like it is setup on the wireless router/modem. Every piece of information must match. The password and SSID are both case-sensitive. So, if your S5 keyboard capitalizes the first letter of the network name, guess what? The Galaxy S5 won't connect. Double-check the information entered as one simple typo, or upper/lower case letter causes login problems.
A Word on Hidden Networks
Many recommend that the average person should leave their SSID broadcast set to On. Hiding your network doesn’t always mean added security. 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 network's information into the Galaxy S5, connection problems persist.
The best way to keep your network working properly and secure is to use the best encryption method available (WPA/WPA2). Furthermore, use a secure password. Consider the next tip a last resort.
Clean Up all the settings
Have you adjusted the settings mentioned above and STILL cannot set up a connection with your Galaxy S5? As a last resort, do a hard reset on the router/modem itself which reverts all settings back to factory default.
The method(s) used to reset a router varies. However, most routers have a reset button (usually on the back or rear of the device). Pressing this button with a paperclip or pen tip for 30 seconds forces a reboot.
Can't find a reset button on your router? Search online for your particular brand of router. Search, in particular, for the hard reset instructions. Some routers (especially Linksys routers) also come with the option to “Restore Factory Defaults” under their Menu settings. Access this setting via the router setup page on your computer.
- Check your network's password. Make sure that it matches the password you are entering on your cell phone.
- Try different wireless channels. Try changing the channels on your router under its wireless settings.
- Use updated encryption methods. Check to make sure that your router uses stronger security encryption such as WPA or WPA2.
- Try changing the network mode(s). Change from the usual “Mixed” setting to other options available. “Wireless-B/G Only” setting.
- Reset router/modem. As the last resort; you can set the router back to factory defaults.
- Check for Hardware problems.
After much research, it appears that Android 5.0 Lollipop had a bug. Remove your Samsung Galaxy S5's MicroSD card and restart the device. Now, try connecting to the Wi-Fi network again. If it works, Great! Update: the subsequent Android Lollipop update resolved this issue.
The above tips help solve Galaxy S5 WiFi problems. However, if you still face Galaxy S5 WiFi issues, then consider taking your Galaxy S5 to a repair shop. Also, consider purchasing a replacement Galaxy S5.
