WIFI issues with Rock 4 SE (Antroid TV)

Hey Guys,
TLDR: WIFI shutsoff after some time, Have to manualle restart the board or go into settings and toggle the wifi again. How to fix this?

Bit of backstory skip this paragraph if you want just to read the issue.
So i found some releated topics but none with the android tv OS. ANd some of those post a rather some years old. So maybe not as relevant anymore (dongle recommentations).
I bought a 4SE to make have a SmartTV which i can configurate as i like and download any app. So i choose antroid (also happy to test others if this is rather a antroid issue).

So either is a antroid tv os issue as its fixed but toggle the wifi setting. But some for some apps i dont find a way to exists them as soon as the wifi is off (e.g. twitch). I have a keyboard + a mouse plugin in is there any shortcut which kills the current app?
Or its a hardware issue as a read that the wifi onboard is not so good. If this is also the case for the SE board what are the current recommended wifi dongles?
