Wi-Fi randomly disconnects and reconnects after a firmware update (Verizon)

Problem: I have a new Galaxy S6 Edge that I updated just recently and so far, not so good because ever since the update was installed, the Wi-Fi in my phone was totally messed up. It can connect to any network but then the connection drops out and leaves me with nothing; no email, can’t browse, etc. It is very annoying and I really can’t use the device to its full potential with this kind of problem. If you could help me figure out what the problem is, I would be very grateful. Thank you in advance.

Troubleshooting: Since we are dealing with a problem that occurred after an update, then you must clear all system caches first as some of them may have been corrupted during the process. After that, try to observe your phone closely if the problem still occurs and if so, disable the Smart Network Switch. Follow the instructions below:

Wipe Galaxy S6 Edge Cache Partition

  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.

Disable Smart Network Switch

  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.”

I hope this helps.

On/Off switch greyed out, Wi-Fi is always On (ATT)

Problem: For some very weird reason the On/Off Wi-Fi switch in my phone is disabled and the Wi-Fi is always on but I really can’t get a good connection; sometimes it connects with a very slow connection but most of the time it just won’t. Even if I go to an area with a different Wi-Fi network, my phone won’t disconnect from my home network and connect to a familiar one. I badly need your help guys. Why is this happening and how can I fix it? By the way, my phone is a Galaxy S6 Edge. Thanks.

Troubleshooting: It’s probably just a glitch that affected the device’s radio services. If you happen to download a firmware update, I suggest you follow the procedure on how to wipe the cache partition above. Glitches that occur after an update are often caused by corrupt caches.

If there was no update or if wiping the cache partition didn’t fix the problem, then try booting your phone in safe mode and from there, try to see if the Wi-Fi switch is enabled. If so, try turning if off and restart to normal mode. It should work after that. However, if it’s still disabled, then you have no other choice but to backup all your data and perform a master reset. Follow the procedures on how to boot in safe mode and do the master reset below:

How to boot Galaxy S6 Edge in safe mode

  1. Turn off your Galaxy S6 Edge.
  2. Press and hold the Power key.
  3. When ‘Samsung Galaxy S6 Edge’ appears, immediately release the Power key and then press and hold the Volume Down button.
  4. Continue holding the Volume Down button until the phone finishes the restart.
  5. When you see Safe Mode on the lower left corner of the screen, release the button.

Perform master reset on Galaxy S6 Edge

  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.

Connected to a Wi-Fi network but cannot browse or download apps (Sprint)

Problem: This problem actually just started today. My Galaxy S6 Edge is somehow connected to my Home Wi-Fi but it couldn’t connect to the internet. Did you get what I mean? I can’t browse using the Internet app, my emails don’t come in and I haven’t received one since the morning, I can’t do Facebook, no Twitter either. It started without any cause or something and it started in the morning when I woke up. Help me. Thanks.

Troubleshooting: Well, first of all, reboot your phone. Some services may have crashed for some reason and they might have caused the problem. Rebooting will refresh your phone’s memory as well as start up necessary services. If that didn’t work and if there was no other significant events that may have led to this issue, then the problem might be in your network. But the thing is all you can do to troubleshoot your network is to turn off your modem and/or router. So please, do that to see if that could make a difference.

You could also further verify if the problem is with your network by trying to browse the internet using your other devices such as laptop, computer, other smartphones, etc. If they can connect just fine, then the issue is with your phone. Try “Forgetting” your Home network in your phone and let it detect and connect to it. However, if you other devices couldn’t connect either, then you should probably call your Internet service provider.

Phone can’t connect to home Wi-Fi network after an update (T-Mobile)

Problem: It’s just weird because after the recent update to my S6 Edge, the device can no longer connect to my home network. Apparently, it could connect before the update because I used my network to download it but the moment it rebooted, it just keeps saying “Obtaining IP address” and won’t actually connect. How come my phone was messed by an update? Please help me guys. Thanks.

Troubleshooting: I understand the phone rebooted itself after the update was installed but try to reboot one more time to see if that would make a difference. If it didn’t, then you should try the procedure I cited in the first problem–wipe the cache partition.

It is apparent it’s a glitch in the firmware and if it were minor, then wiping the cache partition would take care of it, otherwise, you really have to perform a master reset, although I also want you to reboot your network equipment.

Apps automatically update if phone is connected via Wi-Fi (ATT)

Problem: I am always connected to Wi-Fi even at work but there are always time in a day wherein I connect via mobile data. But my problem is my apps automatically update themselves when I’m connected to Wi-Fi without my consent. This phone, an S6 Edge, has been with me for a couple of weeks and I’m still trying to learn more about it since I was with a Windows phone for a long time. So, to sum it up, I really don’t know how to disable the auto update thingy. Can you help me?

Troubleshooting: As part of being “smart” your phone can be set to update its apps automatically when to connected to Wi-Fi or mobile data or not at all. Basically, all you have to do is set the phone to not update its apps so all future updates will be initiated by you. To cut to the chase, here’s the procedure how to do it:

  1. From the Home screen, tap Apps.
  2. Tap Play Store.
  3. Tap the Menu key.
  4. Choose Settings.
  5. Now, tap on Auto-update apps.
  6. To disable automatic application updates, tap Do not auto-update apps.
