T530: Sudden slow WiFi

[patteri]

Hi, new poster here.

I bought a T530 about 6 months ago and it has been working well so far. However last week, my Wifi suddenly went to crawl, I could get download speeds of only < 1Mbit and the ping was over 300ms. Anyway, the next day it sped up, but it no more goes over 20Mbit/s while my network is capable for about 80Mb. My (chinese)phone gets 40M/s and PS4 about the same so it is not because of my wifi network. The Thinkpad had +60M/s before this. I reseted the router multiple times but it didn't help. It's not a software issue either because I mainly use Arch Linux but also have Windows 10 installed, both have the exact same speed when it comes to downloading and latency. I also tried Ubuntu live. I'm sure this is a hardware issue.

This is the wireless card. Should I replace it or is there some things I can do without getting a new card? I located the component and reseated the wires but nothing really happened. I measured(linSSID) the signal and it's -34dBm so shouldn't be a problem with getting "bars".

If anyone has tips I'd be very grateful! Thanks!

Guessing you may have already tried this...
Uninstall the adapter driver in Device Manager -- reboot and then scan for new hardware in Device Manager.
After adapter is reinstalled, see if wireless speeds improve.

Yeah I tried that as well- however it shouldn't have to do with the Linux install right? Anyway I ordered a new wireless chip, I'm too lazy to deal with the original seller and a new chip is dirt cheap apparentally. Thanks anyway for answering.
