so recently i could not connect to 5g netwrok, which worked fine for past few months. After few reboots i reinstalled the drivers (same drivers, got it on hdd) and now connection speed is always 54 mbps on 5g network (it was 390~585 before).
i discovered that its not working (cant connect to router) if i set router to "802.11ac only" or "802.11n/ac mixed" mode (in router settings)
im using pc from exact same spot and signal strenght is excellent. it worked fine before. tried other drivers i got from support (2016) - same 54 mbps
is this adapters hardware fault that it cannot connect to "n" and "ac" networks? or what am i doing wrong?
cant connect to my phones 5g hotspot (0.5m distance), 2.4g hotspot works fine
has no drivers download link
driver i used before from global site version:
