Problem: Galaxy S9 internet connection not working

Hi, I have been having issues with my samsung galaxy s9. it hasn’t been connecting to my internet. it says it connects to my internet but it only shows up as it did and when I try to go on an app it never works it doesn’t say it has an error. it just happened about 2 days ago on the 8th of December. I have tried your methods but they dont work. I would appreciate it if you helped out thanks.

Solution: There’s a long list of possible reasons for this issue. Here’s how to troubleshooting this problem.

Forced restart

Sometimes, this simple procedure can fix bugs that developed after the system has run for a long time. By manually forcing your S9 to reboot, you’re basically simulating a battery pull, which, in older mobiles with removable battery packs, was an effective way to refresh the system. If you haven’t tried this one yet, here are the steps that you can do:

  1. Press and hold the Power + Volume Down buttons for approximately 10 seconds or until the device power cycles. Allow several seconds for the Maintenance Boot Mode screen to appear.
  2. From the Maintenance Boot Mode screen, select Normal Boot. You can use the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Wait for up to 90 seconds for the reset to complete.

Check network signal is strong (If using mobile data)

If internet stops working when using mobile data, the first thing that you want to do is to ensure that your S9 is getting good signal from your network. You have to check that  3G or 4G is enabled to allow faster broadband connection. For the signal, the device must consistently show at least 3 bars. Any intermittent connection can also potentially gives the appearance of total internet absence.

If your S9 has slow 3G or 4G connection, overall mobile data experience may suffer. In this case, you can skip the rest of the troubleshooting steps below and get help from your carrier right away.

Verify wifi is working (if using wifi)

If you don’t use mobile data at all and rely on wifi only, it’s important that you check whether your wifi is working properly or not. You can use another wireless device (phone, tablet, laptop, etc.) to check. If a second device can connect to the internet using the same wifi, the problem must be on your Galaxy S9. Continue troubleshooting it by following our suggestions below.

If all wireless devices are unable to connect to the internet when on the same wifi network, there may be a problem with the router or your Internet Service Provider (ISP). In this case, you want to contact your ISP for help.

Clear system cache

Your Android device uses a special cache called system cache to load apps quickly. To check if your device’s system cache has been corrupted and causing trouble, try to clear the cache partition. 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 Android logo displays, release all three keys.
  4. An ‘Installing system update’ message will show for 30 – 60 seconds before the Android system recovery menu options appear.
  5. Press the Volume down key several times to highlight wipe cache partition.
  6. Press Power key to select.
  7. Press the Volume down key to highlight yes, them and press the Power key to select.
  8. When the wipe cache partition is complete, Reboot system now is highlighted.
  9. Press the Power key to restart the device.

Reset network settings

If internet was previously working on your S9 and it suddenly disappeared, there may be a network configuration issue. You can reset your device’s network settings to see what happens.

  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 S9 and check for the problem.

Reseat SIM card (If using mobile data)

Some users were able to successfully fix network problems by simply disconnecting their SIM cards. If you haven’t tried this before, here’s what you need to do exactly:

  1. Turn off your phone.
  2. Remove the SIM card carefully.
  3. Wait for at least 10 seconds before turning the phone back on.
  4. Then, re-insert the SIM card and check for the problem.
  5. Ensure account with network operator is up-and-running ((If using mobile data)

Reset app preferences

Resetting app preferences is oftentimes overlooked in many Android troubleshooting articles but when it comes to an issue like yours, it might help a lot. It’s possible that one or some of your default apps may not be set correctly, causing this glitch to occur. Because there’s no way to know if this guess is true, what you need to do is to simply ensure that all default apps are turned on. Here’s how to do that:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Reset app preferences.
  5. Restart your S9 and check for the problem.

Factory reset

Wiping a device and returning everything to factory settings is drastic in most cases but it may be a necessary solution if the problem is not yet resolved at this time. Make sure to create a backup of your personal data before doing it. Follow the steps below on how to factory reset your S9:

  1. Create a backup of your data.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. 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).
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

Get help from your carrier

If you think there’s a problem with your account, or if nothing happens after a factory reset, you should get help from your network operator.
