Signal strength problems with Intel(R) Wi-Fi AX200 160Mhz

[vifilix]

I bought this wifi card recently to be used in a personal computer and it worked amazing up until yesterday. What is odd, though, is that the wifi card was working perfectly fine on that day and when I turned off the computer to have a meal and then went to turn it on again, the wifi card seemed to want to act poorly.

My internet download speeds with this card were an average 111 Mbps in my household before the incident yesterday and now they are a measly 3-4 Mbps. As a result, any online game is unplayable due to constant packet loss and ping spikes, some of which hit above 15000 ping. Outrageous!

I have tried redownloading drivers, reverting to old drivers, using a different DNS server, rebooting the router, trying less crowded channels for the router to use, messing with a few settings that have worked for others in device manager. EVERYTHING! But nothing has worked. 

It is definitely the wifi card as my crappier usb wifi adapter which before yesterday was 2x as worse as this card produces its usual result of 50 Mbps.

On a side note, the wifi card loves to use 2.4 Ghz speeds even though I set it to prefer 5 Ghz after the incident.

Any help would be MUCH appreciated!
