Samsung Galaxy S7 Edge can no longer connect to Wi-Fi after Android 7.1 Nougat update [Troubleshooting Guide]

It’s a bummer that your #Samsung Galaxy S7 Edge (#S7Edge) could connect to your home Wi-Fi and actually used it to download the latest firmware update–Android 7.1 #Nougat–but when the installation completed and the phone rebooted, the device can no longer connect to Wi-Fi. This kind of problem is divided into several variations but the most common is that the phone can still find the hotspot and when the user tries to connect, it will attempt to do so but eventually fails.

Other issues include the disabled Wi-fi switch, which leaves your device not connected to the network and since the switch is greyed out, you cannot turn the Wi-fi on no matter what. There are also situations wherein the phone may try to connect to a known hotspot but fails or just keep saying “Acquiring IP address…” but instead of saying “Connected,” it would say “Saved.”

In this post, I will tackle the first issue I cited and I will write a different post for the other issues. So, if you own a Galaxy S7 Edge device that has recently been updated to Android 7.1 Nougat and are bugged by this issue or a similar one, continue reading to know how to troubleshoot your device.

Troubleshoot Galaxy S7 Edge that can no longer connect to Wi-Fi after the firmware update

I cannot stress enough how important Wi-Fi is especially if you are into playing battery and data extensive games or apps. It is, therefore, imperative that you, at least, try to troubleshoot your device if it could no longer connect to a Wi-Fi network after an update and this is how you do it…

Step 1: Try to see if the problem is caused by your apps

It is very important that you know if your apps have something to do with the problem because it’s always possible that some of the apps you installed are no longer compatible with the new firmware. Find those apps, clear their caches and data and if that won’t work, uninstall them one-by-one until you find out which of them are causing the problem. To do so, boot your device in safe mode and try to connect your device to a Wi-Fi network to know if that works. This is how you start your phone up in safe mode:

  1. Press and hold the Power key.
  2. As soon as you can see the ‘Samsung Galaxy S7 EDGE’ on the screen, release the Power key and immediately hold the Volume Down key.
  3. Continue holding the Volume Down button until the device finishes rebooting.
  4. You may release it when you can see ‘Safe mode’ in the bottom left corner of the screen.

If the problem still occurs in safe mode, then we might be facing a problem with the firmware itself, otherwise, you just have to find the apps that are causing the problem and do the following:

  1. From the Home screen, tap the Apps icon.
  2. Find and tap on Settings.
  3. Touch Applications and then Application manager.
  4. Swipe to ALL tab.
  5. Find and touch the app in question.
  6. Tap Storage.
  7. Tap Clear cache and then Clear data, Delete.

To uninstall an app, just follow the same procedure but tap Uninstall.

Step 2: Find out if the problem is caused by corrupt system caches

For a phone that has just been updated, it’s possible that some of the system caches used by the previous firmware have already become obsolete or are already corrupt. If the new system uses them, issues like this may occur. In fact, we’ve already covered issues like this before that were caused by corrupt system caches, so it’s not really the first time we’re covering this issue. To rule this possibility out, here’s what you have to do:

  1. Turn off the phone.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished wiping the cache partition. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

If the problem still persists after wiping the cache partition, then you have no other choice but to reset your device.

Step 3: Master Reset your phone

This procedure will bring your phone back to its factory defaults but it can potentially fix any firmware-related issues especially ones that occur after the firmware got updated. The catch is that all your files and data that are saved in your phone’s internal storage will be deleted together with your settings and preferences so make sure to backup everything first before following these steps:

  1. Turn off your Samsung Galaxy S7 Edge.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key. NOTE: It doesn’t matter how long you press and hold the Home and Volume Up keys, it won’t affect the phone but by the time you press and hold the Power key, that’s when the phone starts to respond.
  3. When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds. NOTE: The “Installing system update” message may show on the screen for several seconds before displaying the Android system recovery menu. This is just the first phase of the entire process.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

If the problem still occurs after the reset, then the firmware has to be re-installed but it has to be done manually and you cannot do so on your own as the warranty will surely become void.
