I checked every points of the "Case 2" and nothing changed it's still doing that disconnecting every couple minutes for a couple seconds which is barely enough to kick me out of games or discord sometimes if i ping -t the router i'm connected to it stay between 1 and 4 ms, then sometimes jump to 30-80 ms on a single ping i have the TU3 Nano which is supposed to be Dual band but i think the router itself doesn't support 5GHz (i don't have access to it so i don't even know what model it is) the fact that it's 2.4GHz should only impact the max speed (a blazing 40 Mbits/s) but i really think it's the wifi key that somehow just "pause" for 5 seconds every now and then i have the driver installed from teh website and did all the updates i could find on my PC
