Anyone having issues with S20 and S21 with frequent disconnections from wifi after software update 3-4 months ago. 2-3 updates came after but this issue still not resolved.

Hi, We suggest you to remove and manually connect to Wi-Fi Try forgetting and then re-adding the Wi-Fi network. Navigate to and open Settings. Tap Connections, and then tap Wi-Fi. Tap the network you want to remove, and then tap FORGET. Tap Add network. Enter the Network name (SSID). Tap the Security field and then select the encryption type for the network you are adding. If you chose an option other than None, tap the Password field, enter the password, and then tap Connect. Now go back to Settings >> Wi-Fi and reconnect to network to check if the problem is resolved.

You can also try Resetting your Network Connections, from Settings > General Management > Reset Network Settings.

I tried everything. Nothing helps. After latest update a week ago, the issue gone worse. Now everytime when I needcto use phone even though in 10 mins interval, I have to turn off and on wifi from phone to get connected to wifi. Otherwise it doesn't work. I am keep getting message from apps that something went wrong or no internet connection.
