so I bought an aorus motherboard without onboard wifi (forgot witch one) and the wireless- AC2100 PCE-AC58BT wifi adapter, the moatherboard broke within a week so I then got an aorus z-390 pro wifi gaming motherboard as a replacement and suddenly the compute kept crashing anytime i tried to connect to wifi. i tried a few things and found out that it would work if i took the wifi card out but i need it in cuz my parents gonna change the house wifi to 5hz or whatever that is and my onboard can only connect to 3hz (i think its hz i dont know lemme know if its the wrong abbreviation) so is there a way to disable the onboard wifi? i thought it would do it on its own but i guess not. any help would be amazing!!!
