Air link doesn't work anymore on quest 2

Yesterday it was working just fine.

Today I tried to connect but it only kicked me out saying that my wifi is weak (which it isn't, it's very fast). Now it ended up showing my PC as "not connected" I tried everything; Restarting my Pc, Quest 2, Router. I reinstalled the App and it still doesn't work. The software of the Quest 2 is the newest and the driver is also the newest for the app and all I legit checked it all and it doesnt work anymore. Which sucks I only have games on my pc and not on the quest 2.
