What to do if Galaxy S10 5G wifi won’t work | wifi keeps disconnecting

If your Galaxy S10 5G wifi won’t work and you have no idea how to fix it, follow our suggestions below to fix it.

S10 5G wifi won’t work fix #1: Check router

Before you do any troubleshooting steps on your Galaxy device, it’s good if you can make sure that the problem is not coming from your wifi network. There may be an issue with the router or your Internet Service Provider (ISP) that’s why your Galaxy S10 5G wifi won’t work. To do that, try to connect another wireless device to the same wifi and see if wifi connection is working normally. If you have another phone or laptop, use that to test the router. If a second device will have the same wifi issue, then it can be a router or ISP problem. In this case, make sure that you restart the router. If that won’t work and wifi is still not working, contact your ISP for more troubleshooting help.

S10 5G wifi won’t work fix #2: Forget wifi

If there’s no problem with the router or your ISP, then the rest of your troubleshooting should focus on your Galaxy S10 5G. First, make sure that you disconnect from your wifi network. Forgetting wifi as a troubleshooting step is often useful when wifi connectivity is erratic. To do this, simply select the wifi icon, then tap and hold on the name of your wifi. To disconnect, select Forget network. After that, try connecting to your wifi once again and check for the problem.

S10 5G wifi won’t work fix #3: Restart device

If your Galaxy S10 5G wifi still won’t work, the next move is to refresh the device itself. You can do that by performing a soft reset. It’s basically a restart although you’ll be trying to simulate the effects of a “battery pull.” On older Samsung devices, removing the battery was a way to restart the system, especially if there’s a problem with the Power button, or if the system has frozen. 

Soft reset is one of the basic troubleshooting steps for any app issue. It’s simple and often effective in dealing with minor bugs and fixes. In most instances, wifi troubles are temporary and caused by an app or software bug. Make sure to perform this troubleshooting step in this case. Here’s how: press and hold the Volume Down button and the Power key at the same time for 10 seconds or until the device’s screen turns on.

If doing the regular restart won’t help, then try this:

1. Press and hold the Volume Down button first and don’t release it.
2. While holding it down, press and hold the Power key.
3. Keep both keys held down for 10 seconds or more.
4. The second restart procedure tries to simulate the effects of removing the battery pack. On older devices, disconnecting the battery is often an effective way in fixing unresponsive devices. Hopefully, your wifi troubles will get fixed by this procedure. If nothing changed though, proceed to the next suggestions.

S10 5G wifi won’t work fix #4: Reset network settings

Sometimes, network issues are caused by incorrect network configuration. Make sure that your Galaxy S10 5G is set up correctly with these steps:

1. Open Settings app.
2. Tap General management.
3. Tap Reset.
4. Tap Reset Network settings.
5. Tap RESET SETTINGS button to confirm.
6. Restart your Galaxy S10 5G and check for the problem.

S10 5G wifi won’t work fix #5: Refresh system cache

If the wifi issue occured after a system update, there might be a problem with the system cache. Try to clear the cache partition to see if it’s a cache issue. Here’s how:

1. Turn off the device.
2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
4. Press the Volume down key several times to highlight ‘wipe cache partition’.
5. Press Power button to select.
6. Press the Volume down key until ‘yes’ is highlighted and press the Power button.
7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
8. Press the Power key to restart the device.

S10 5G wifi won’t work fix #6: Check wifi on Safe Mode

Some apps may interfere with Android and other apps. To see if one of your third party apps, the ones you downloaded, is the reason for problem, boot the phone to safe mode. On safe mode, only pre-installed apps will be allowed to run so if the problem won’t return, that’s an indication of a bad app problem. If you noticed that calling issue started messing up after installing a new app, try to uninstall it and see if it fixes it. If you can’t remember any app that you install that may lead to this problem, then go ahead and restart the phone to safe mode. Here’s how it’s done:

1. Turn the device off.
2. Press and hold the Power key past the model name screen appearing on the screen.
3. When SAMSUNG appears on the screen, release the Power key.
4. Immediately after releasing the Power key, press and hold the Volume down key.
5. Continue to hold the Volume down key until the device finishes restarting.
6. When Safe mode appears in the bottom left corner of the screen, release the Volume down key.
7. Check wifi and see if it’s working.

Safe Mode works by blocking third party apps from running. If there’s no problem on safe mode, that means a bad app is causing it. To identify that app:

1. Boot to safe mode.
2. Check for the problem.
3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
4. After you uninstall an app, restart the phone to normal mode and check for the problem.
5. If the problem still remains, repeat steps 1-4.

S10 5G wifi won’t work fix #7: Factory Reset

At times, wifi troubles are due to some unknown software bugs. In many cases, these bugs are cleared with factory reset. If your Galaxy S10 5G wifi still won’t work at this time, make sure to do a factory reset. This will clear your personal data so be sure to back them up ahead in order to avoid losing them. Learn how to factory reset below.

7. Tap Delete All to confirm action.

Method 2: How to hard reset on Samsung Galaxy S10 using hardware buttons

1. If possible, create a backup of your personal data ahead of time. If your problem prevents you from doing that, then simply skip this step.
2. Also, you want to make sure that you remove your Google account. If your problem prevents you from doing that, then simply skip this step.
3. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
4. Press and hold the Volume Up button and the Bixby button at the same time.
5. While still holding the Volume Up and Bixby keys, press and hold the Power button.
6. The Recovery screen menu will now appear. When you see this, release the buttons.
7. Use the Volume Down button until you are highlighting ‘Wipe data/factory reset.’
8. Press the Power button to select ‘Wipe data/factory reset.’
9. Use Volume Down to highlight Yes.
