@gogoulis hello, I'm back on 1.3.0 0.9.1 v0001.0 Build 210608 RC.66100n and the situation has somewhat stabilized. However the speed is not good. And of course there is still no band selector on this...

Good evening, I used to be on version 200511. After upgrading to the latest firmware 210608 with ISP file 21052700, the internet connection has been constantly disconnecting and switching bands....
