First solution: Restart your phone.

To rule minor glitches out from the possible triggers, try performing a soft reset or reboot your Samsung S9 first. This will not affect your personal information or any critical data saved in the internal memory of the phone so creating a backup won’t be needed. Here’s how you do it:

  2. Tap the option to Power off.
  3. Tap Power off again to confirm.
  4. After about 30 seconds, press and hold the Power button again until your phone boots up.

See if that fixes the problem. If not, then move on to the next solution.

Second solution: Forget Wi-Fi networks on your phone.

There are times when your wireless network gets corrupted and becomes unstable thus resulting to frequent Wi-Fi drops or intermittent connectivity. To fix the problem, you need to refresh your Wi-Fi network either by rebooting the router or forgetting and readding your Wi-Fi network on the phone. Here’s how:

  2. Tap Settings.
  3. Tap Connections.
  4. Tap Wi-Fi.
  5. Select the Wi-Fi network you wish to forget or remove. Or you can also delete all saved networks on the phone to prevent any of them from causing conflicts.
  6. Tap Forget to confirm.

Restart your phone to add your Wi-Fi network again with these steps:

Wait until your device is connected. You may do some test browsing to see if the Internet is already working stable.

Third solution: Reset network settings.

There are many factors that can mess up your network settings and likely result to problems like this. Faulty updates are usually the culprit. Hence if the problem started after installing a new software update, it’s possible that your network settings have been altered automatically when the update was implemented. To fix the problem, you can try performing a network settings reset with these steps:

  1. Swipe up on an empty spot from the Home screen to open the Apps tray.
  2. Tap Settings.
  3. Tap General Management.

Fourth solution: Wipe cache partition.

Temporary files that are stored as cache in the system partition can also cause you the same trouble when they crashed. To make sure this isn’t inflicting you this trouble, wiping the cache partition on your Samsung S9 can help. Here’s how it’s done:

  2. Press and hold the Volume Up key and the Bixby/Home key, then press and hold the Power key.

Wiping the cache partition doesn’t delete your data and personal information from the internal storage so it doesn’t result to any sort of data loss.
