hello, so my internet to my main pc has been off and on for the past year, but most of the time working. For some reason the past week my internet has been insanely bad, it'll work for 2 mins and drop out for 30 second on repeat. I'll run anything more then discord or youtube and it will crash, but all my other devices run fine in the same room on the same wifi. i use a wifi card- TP link AC 1900. plz help me, and i've tried installing drivers again
