Hi,

I'm facing several Wifi issues ever since the last security patch update (1 March) on my Samsung Galaxy M30s. 

1) "Network speed" of the Wi-Fi automatically goes down to "6Mbps" every few minutes (I've to disconnect and reconnect to the WiFi over and over again). I have a 100 Mbps connection. All other devices connected to same network work just fine.

2) I often get "Connected without Internet" while  my other phones are working perfectly fine on the same network! I have to restart my phone several times to get it to work. It's really frustrating. 

3) My cellular network automatically drops from WiFi calling to LTE every few minutes (5-10). I have to restart Wifi, then restart Wifi calling for it to work. I live in an area where LTE connection is poor, so I have to rely on WiFi calling only.

 

Please release a fix as soon as possible! (I've been through several forums and I'm quite sure I'm not the only one facing these issues).

 

Things already tried but didn't work:

1. Phone restart

2. Network reset

3. Factory reset

4. System cache cleanup

5. Router reset

 

PS: I never had these issues on Android 9. Even the battery life was much better on it. Wish I could just downgrade it back.

How many devices are connected to your WiFi at a given moment of time?

There are three, including my M30s, my old phone (iPhone 7) and my laptop. Even if my friend connects his phone when he comes here, works fine on his.

Try these steps, if it still doesn't works then it's probably a faulty wifi adapter.
