Cut the Wi-Fi through the Airplane Mode

The purpose of enabling Airplane Mode is to cut the wireless connection for a few seconds. After turning on the Airplane Mode for a few minutes, you should turn it off and switch on the Wi-Fi connection again. It often works for most smartphones, even if it is a temporary fix.

Even if it is a temporary fix, nothing is stopping you from using it. Slide down the Notification Shade, and you should be able to locate the Airplane Mode icon among the options.

Click on it once to enable the Mode, and the current Wi-Fi connection will cut out. You should click on it after a few minutes to deactivate it.

Refresh the Wi-Fi Connectivity

Another temporary fix is to disconnect the Wi-Fi and then turn it back on just like the Airplane Mode method. You can perform this operation from the Notification Panel, without needing to activate any other features.

Restart your Galaxy S9

Another way to fix the Galaxy S9 Wi-Fi issue is by rebooting the device itself. If there is a background app that is slowing down the Wi-Fi connection, then the restart should fix the issue and allow your smartphone to function properly again.

Restart the Modem

In the event that your Galaxy S9 is the part causing the issue, then you should consider restarting the modem. You have a basis for suspicion if your other devices at home, or in the office connected to the modem are experiencing the same Wi-Fi issues.

Forget the Current Connection

This is different to simply turn the Wi-Fi on and off because it actually involves deleting all the data that your Samsung Galaxy S9 has previously acquired from the connection. To perform this process, you will need to access your smartphone Wi-Fi settings, locate the network you are currently connected to, click on it and select the Forget option.

After doing this, reboot the device and head back to the settings menu, scan for new networks and reconnect to your previously existing connection. This method offers high chances of solving the Wi-Fi problem.

Clear the Cache Memory

More often than not, a corrupted cache is most likely the source of different problems plaguing the Samsung Galaxy S9. Its effect on the phone is that it gradually slows down your Galaxy S9, so it is best you wipe the cache and allow it to rebuild itself.

After that, your Wi-Fi connection should be fully operational and solid at all times.

Hold down the Power, Volume Down, and Home buttons simultaneously
When the Android logo boots, release the Power button
When the phone restarts, release both the Volume Down and Home buttons
Navigate to the Recovery Mode, locate the Wipe Cache Partition option with the Volume Down button
Select the Wipe Cache Partition option via the Power button
After doing this, use the Volume Down button to click on the Reboot option and the Power button to activate the reboot

When you are done with the instructions highlighted above, the phone will reboot to its normal functioning mode. Your Wi-Fi connectivity should start working correctly henceforth. If there are still any existing issues, your next logical step is to take your Samsung Galaxy S9 to a Samsung store for advanced evaluation.
