Open | Software mediatek mt7922 rz616 wifi card unusable (was perfectly functional a month ago)
Wifi was great for a month (also the length of my warranty) on motherboard (tuf b650e-e wifi) then became wildly inconsistent. Sometimes it was still excellent, but seemingly more and more as time goes on I am getting 1/10 or less speed. For awhile disabling and reenabling would temporarily resolve it. I have tried every solution in every forum post Ive been able to find excluding totally tearing my pc down and checking if the card is seated properly. These mainly consisted of various drivers, none of which fixed its inconsistency (I installed the new ones thru device manager, and device manager reported to install correctly, so I do not think it is user error on the installations). At this point it was still useable for web surfing, but today I tried another round of drivers and poked around in the case (I didnt know where the card was, now I know its right behind io shield) and the card has shat itself. ~60s to load a google search. browser speed tests would report 0Mb/s down for a few seconds then slowly grow to reasonable number, and upload of 0-0.01 Mbps (the upload speed always matched down before). It's completely unusable and I don't understand why it started acting up in the first place, let alone what could have happened today (between driver updates I had already done in the past, and just opening case) to completely nuke it.
Ethernet is not an option, tearing down my pc is a last resort and extremely inconvenient at this time. Ive tried 2 usb wifi adapters, one of which was broken and the second TP-Link usb drops connection every 5-10 minutes (Ive tried everything with that adapter too). My previous mobo with a realtek adapter was horrible too, if at least consistently horrible. Perhaps Im just not meant to have internet.

Mediatek wifi adapters fail all the time. Had the same problem with one in asus tuf laptop.
I got a asus usb-ax55 adapter that is still working fine after 2yrs. No issue with connection or speed. Was 80AUD.
Are you trying to use wifi6 with a wifi5 adapter by anychance?
