A12 WIFI issue - Consistently disconnecting/reconnecting

(Topic created on: 10-21-2022 12:41 PM)
Beginner Level 2

I've had my A12 for over a year now and this problem has consistently persisted, minute by minute the WIFI disconnects and I have to manually reconnect to it all the time. As soon as I reconnect again it disconnects. I am extremely frustrated with this device even after multiple resets, clearing all connections, resetting my router, forgetting the connection and re-connecting the problem it still continues. None of the other devices in my house have this issue it is only the A12. After the most recent firmware update the problem has just got even worse, it barely stays connected to the WIFI which makes it extremely difficult to use any apps because I have poor  4G network signal where I live anyway!
