How to fix Samsung Galaxy S6 Edge that won’t connect to Wi-Fi, mobile data

There are two ways a smartphone can connect to the Internet; either it connects via a Wi-Fi network or through a mobile data network. But what if your phone can’t connect any of them?

We’ve been receiving emails from our readers seeking assistance because their new Samsung Galaxy S6 Edge won’t connect to Wi-Fi or mobile data. But the fact is, this problem can happen to any smartphone in the market today. It is not specific to one device only and corrupt firmware or modem has always been one of the most common reasons. Devices with custom ROMs or firmware are often the victim of this.

In the case of the Galaxy S6 Edge, however, it could be a glitch in the system or it becomes overly sensitive in evaluating signal strengths between the two networks. Samsung built its device to be “smarter” than its competitors and one way to do that is to keep it connected all the time…or almost all the time. That is the reason why it is programed to automatically connect to another network with more stable signal.

In this post, I will walk you through simple troubleshooting procedures that will help you determine what the problem with your phone really is and why it’s unable to connect to either a Wi-Fi network or a mobile data network.

Samsung Galaxy S6 Edge connects to Wi-Fi but disconnects automatically

Problem: Hi droid guy. I got a problem that I hope you can help me with. My new Galaxy S6 Edge can connect to Wi-Fi network just fine and I can actually download apps, browse the web, do Facebook and Twitter and all the usual stuff. The problem is that at some point in time, it will automatically disconnect from the network and then reconnect. As a result, I can’t get good signal and everything I do that require internet connectivity will be put to a stop. Please help me how to fix this as I need my phone badly and seriously, I bought this phone with high hopes but it seems like I made a wrong decision. Thanks. — Sarah

Troubleshooting: This is one of the best example that your phone is so picky in choosing between networks it wants to connect to. More often than not, this problem occurs when both Wi-Fi and mobile data are turned on. If the phone detects that the Wi-Fi network signal is unstable or weaker than the mobile data network signal, it will automatically connect to the other network. It’s easy to address this kind of problem. Just follow the steps below and you’ll be fine:

  1. Swipe down from the top of the screen with one finger.
  2. Tap the Settings icon on the upper-right corner.
  3. Tap the WiFi icon.
  4. Tap the Menu icon on the upper-right corner of the screen.
  5. Choose Advanced from the drop down.
  6. Uncheck the box next to “Smart network switch”.

Galaxy S6 Edge won’t connect to Wi-Fi network after an update

Problem: Hi guys! Immediately after a minor update, my Samsung Galaxy S6 Edge cannot connect to my Wi-Fi network. I already did a hundred reboots and still the same. Thinking it was my Wi-Fi network that has issues, I rebooted my modem/router as I did when it happened before but to no avail. If I’d known it would become like this after the update, I shouldn’t have downloaded it in the first place. I need your help guys. I don’t want to see my money go to waste just because of this piece of junk. I need to be connected to Wi-Fi at home or at work because I’m using this phone for my emails. If you could guide me in fixing this problem, I would surely be grateful. Thank you! – Geraldine

Troubleshooting: Hello Geraldine. The new firmware may have somehow messed up some data responsible in making the modem work properly. More often, it’s the cache that gets corrupted during the update but there are also times when some data get messed up. That said, let’s avoid the messy part in troubleshooting this issue, so we’ll have to clear the caches first. To do that, you need to boot the phone in recovery mode. Just follow these steps:

  1. Turn off the device.
  2. Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  3. When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
  5. Press the Volume Down key to highlight ‘wipe cache partition.’
  6. Press the Power key to select.
  7. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  8. Press the Power key to restart the device.

Again, this procedure will clear just the caches. If it didn’t resolve the problem, then you will have to undergo a more complicated procedure and that is the master reset. Before you do that, make sure you make a backup of every important data you don’t want to lose, then follow these steps:

  1. Turn off your Samsung Galaxy S6 Edge.
  2. Press and hold the Volume Up, Home and Power keys together.
  3. When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  4. Wait until the Android Recovery Screen appears after about 30 seconds.
  5. Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  6. Press the Vol Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
  7. After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

Galaxy S6 Edge can’t connect to internet through mobile data network

Problem: I have a Galaxy S6 Edge which I purchased online unlocked. I called one of the service providers here in the U.S. and have it working under their network. It worked fine for a couple of months until the recent update. After I downloaded the update, my internet no longer works. I can only get on the internet when connected to Wi-Fi but other than that, nothing. Could it be possible was reset during the update? How can I make the internet work again? — Clay

Troubleshooting: Hey Clay! If the internet connectivity was lost after an update, then it can be that the APN was reset during the process. This is very common for unlocked phones as they were not natively programed to work under a specific network. I don’t know what your service provider is but the best thing to do is call the tech support and ask for the correct APN settings for your phone. You may also ask the rep to walk you through setting up the APN in your phone. I think that’s all you need to do to fix the problem.

Galaxy S6 Edge disconnects from mobile data network automatically

Problem: I have a new Galaxy S6 Edge that I got from Verizon. Together with it is a plan with unlimited data. While the phone works perfectly fine, there are times when it automatically disconnects from the network and search for other networks to connect to. Consequently, my internet connection is interrupted until it can reconnect back to the network. I have asked a couple of friends but they, too, don’t know what to do. Is there something wrong with the hardware of my device? Please, I need your help. Thanks. — Mica

Troubleshooting: Hello Mica. Actually, your problem is the same as the first issue I addressed in this post only that your device connects to mobile data network instead of Wi-Fi. Your phone disconnects from the network if it detects weak signal coming from the tower but since there are no other known networks in range, it’ll search and reconnect. If there were known Wi-Fi networks in the vicinity, it may connect to one of them. That said, the only way to prevent this problem from happening is this:

  1. Swipe down from the top of the screen with one finger.
  2. Tap the Settings icon on the upper-right corner.
  3. Tap the WiFi icon.
  4. Tap the Menu icon on the upper-right corner of the screen.
  5. Choose Advanced from the drop down.
  6. Uncheck the box next to “Smart network switch”.
