I have a dilemma right now on minecraft, in fact when I connect on my 5ghz network I have huge lags, I get kicked for timeout and I can hardly do anything, however before when I connected on 2,4ghz everything worked fine and minecraft had no lag. The problem? the driver of my wifi card is completely broken, and I can't connect on my 2.4ghz network while I can connect on my phone! it doesn't make any sense. I have a very good wifi card (intel wifi 6 ax201 160mhz) and I have the fiber network (don't know if that makes sense i don't talk english sorry ^^') so I'm supposed to have a very good connection. Thank you for listening to me, hopefully someone has the solution.
I used to have internet on my laptop, but idk what happened electricity went gone for 2 minutes and since then when I try to connect to my wifi from my laptop it says "cannot obtain ip address" or something like that, but on my phone works fine!
