Samsung Galaxy S7 Edge can no longer connect to a Wi-Fi network after Android 7 Nougat update, other internet issues [Troubleshooting Guide]

The Android 7 #Nougat update for the #Samsung Galaxy S7 Edge (#S7Edge) is supposed to bring improvements to the phone’s overall performance but it seems like many owners encountered some really serious issues shortly after updating their devices. In fact, Samsung halted the update and is probably doing its best to address them before making the update available for its users again.

In this post, I addressed three of the most common Wi-Fi related issues with the S7 Edge that occurred shortly after the Nougat update. If you own this device and are currently being bugged by a problem or two especially if it’s related to Wi-Fi or internet connectivity, then I suggest you continue reading before to understand what these problems are all about and how to fix them. Here’s the list of the issues you can find in this post:

Galaxy S7 Edge cannot connect to home Wi-Fi after the Nougat update

Problem: Shortly after the Nougat update, my internet connect got interrupted or got cut off completely. I was actually surprised when it happened because I was connected to that same hotspot while downloading the update and shortly after the installation was finished, I could no longer browse the web. Apps that require internet connection no longer works, emails don’t get sent or received and of course, the Wi-fi icon doesn’t show it’s connected. I already tried what you guys suggested like forgetting the network and allow the phone to detect and connect to it but it just says “Connecting” but nothing happens. Has Nougat messed up my device? How can i fix this? Thanks.

Troubleshooting: It’s really unfortunate that your phone got this problem shortly after the Nougat update because instead of enjoying it with its new firmware, which is supposed to make it better, you’ll be spending time looking for solutions that may help it regain its capability to connect to a Wi-Fi network. Apparently though, the new firmware has something to do with it but it doesn’t necessarily mean the firmware itself is the problem. There’s always that possibility wherein old system cache got corrupted and led to this issue, or maybe some system files or data no longer works with the new system. With that being said, here’s what I suggest you do to try to fix this problem…

Step 1: Reboot your S7 Edge in Safe Mode and connect to a Wi-Fi hotspot

First of all, let’s try to rule out the possibility that the problem is caused by one of the third-party apps. Yes, it is very much possible that some of them are yet to be updated to work with the Nougat and so doing this procedure will temporarily disable all of them giving way to just the pre-installed ones. If the cause is one or some of them, the phone should be able to connect to Wi-Fi while 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 your phone connects to a Wi-Fi hotspot while in this state, then you just have to find the apps that are causing the problem and uninstall them. But it’s easier said than done because we really don’t have a clue at this very moment which one it is. So, I suggest you just backup your data and files and then do the factory reset.

  1. From the Home screen, tap the Apps icon.
  2. Find and tap Settings and then touch Backup and reset.
  3. Tap Factory data reset and touch Reset device.
  4. If you have screen lock feature turned on, enter your password or PIN.
  5. Touch Continue.
  6. Tap Delete all to confirm your action.

On the other hand, if the problem still persists even in safe mode, then we might be facing a firmware-related issue. Move on to the next step.

Step 2: Restart your device in Recovery Mode and wipe the cache partition

As I said at the beginning of this section, there’s a possibility that some system caches got corrupted during the update process or others may have become incompatible with the new system. Since we cannot delete caches one by one, we just have to wipe off the partition where they’re saved and to do that, you have to reboot your S7 Edge in its Recovery Mode and wipe the cache partition:

  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.

Step 3: Backup data and perform Master Reset

If the problem still occurs in Safe Mode and wiping the cache partition didn’t fix the problem, then you have no other option but to reset your device and make sure you backup your important files and data before doing so:

  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.

Galaxy S7 Edge keeps disconnecting from Wi-Fi after an update

Problem: Hi, I have an S7 Edge and while I bought it second-hand, it has been working pretty since I got it later last year. Needless to say, the phone was still in crisp condition when I got it. I did receive quite a few firmware update notifications and just recently, there was another notification asking me to update the device. However, shortly after the update got completed, I’m getting kicked off my internet. I am connected to my home network and my phone automatically disconnects itself from it but then reconnects after a few minutes. I don’t want it do that. Can you help me?

Troubleshooting: It looks like your device firmware was messed up after the update, it’s pretty obvious that it was caused by a new installed software. But, you can’t set aside the possibilities of third-party apps causing the issue as well. The best thing you can do now is to narrow down the issue, since we don’t know what causes it, we recommend performing a basic troubleshooting procedures.

You can start by performing a force reboot your device. This procedure is the most basic and the first method that you should perform. It can fix a minor system glitch and a system refresh is needed, if you haven’t done it yet. Just press and hold the Power key and Volume Down for about 7-10 seconds, then allow your device to reboot.

If it keeps on disconnecting, try to refresh your router where you connect your Wi-fi from. A simple turn ON/OFF would do the refresh. Then connect you device again and see if there’s a progress. It could be that your router lost a connection from the service provider or for any reason encountered a minor issue and needed to restart.

If the issue remained, then we can step up our troubleshooting procedure to the next level. You can proceed clear the system cache partition, it could be that some files are corrupted or damaged during the update process. And since we are not able to clear those files one-by-one or have an access to it, we will do the general clearing procedure. You can refer the steps above on how to clear the system cache partition.

In case after clearing the system cache partition and the issue still remained, then you can try removing the Wi-fi connection from your device by deleting it and connect to it again by entering your Wi-fi password. The main purpose of doing it is to successfully connect to your device without the interruptions or the frequent disconnection issue.

Now, this is the last procedure that we can recommend performing if the issue still remained. You can try and reset the network setting, it will clear all saved network connections and it’s passwords and enter it again if you want to connect. Here’s how..

  1. Go to Settings
  2. Tap Backup and Reset
  3. Tap Reset Network Settings
  4. Tap Reset Settings

NOTE: If a PIN, password, fingerprint, or pattern is needed, then enter it

  1. Tap Reset Settings
  2. A notification message will pop-up for confirmation

If all procedures recommended did not resolve the issue and still keeps on disconnecting, then you can perform a master reset to your device. But this procedure is optional, you have to perform this before bringing your device to a tech, it might save you a trip. All you have to do is to start making backups of the important files stored in your device and save to your SD card, flash drive or PC. Then you can refer above for the steps on how to perform the master reset above.

Otherwise, bring your device to a tech it could be experiencing a more serious issue that only the professionals can handle, and bring the necessary documentation like the warranty if this device is still days old or covered the repairs.

Galaxy S7 Edge Wi-Fi switch is greyed out or disabled after an update

Problem: I’m not sure if you guys already covered this problem but are you familiar with issues involving toggle switches that are disabled or greyed out? In my case, it’s the Wi-Fi switch that got disabled or greyed out and I think it was turned off before the problem occurred leaving my phone without internet connection via Wi-Fi. Last month I got Wi-Fi setup in my home because I have a lot of devices that require internet connectivity. And while I also did subscribe for unlimited data plan with my phone, it couldn’t suffice my need for stable connection that’s why I decided to have Wi-Fi in my home. However, this problem started with my phone and I just don’t know how to fix it. Please if you know what I have to do to fix this problem, let me know. Thanks.

Troubleshooting: This issue is common not just in Galaxy S7 Edge but to other Galaxy lines also like; S4 and S5. As you mentioned that the toggle switch had been greyed out after the update, then most likely it is a firmware related issue. At this point, all you need to do is to rule out the possibilities what is the culprit. The first thing that you need to perform is to boot your phone in Safe mode to figure it out if there were downloaded applications triggered the issue.

This diagnostic state will prevent all third-party apps from running and if the issue won’t persists while in this mode, then there’s an app responsible for it. Find that app and if possible uninstall it to prevent the issue happening again. However, if the problem still happening on your phone you can perform the next procedure.

After booting on Safe mode and nothing’s changed, then you can do the next procedure by wiping the system cache of the phone. This particular procedure will delete all old caches in the system so that the device will create newer caches that is compatible to the new system of your phone. To perform the procedure you can follow the provided steps above.

However, after booting it on Safe mode and wiping the cache partition and still the switch is greyed out then the only thing that you should do is to reset your phone. By bringing it back to its factory default there is a big chance that the problem will be fixed. But remember that this procedure will delete all your files including your contacts, videos and important files stored on your phone. So, before resetting the phone try to backup all of it.
