I was checking my wifi stats today that I suddenly noticed a sudden change in signal strength, from being -19 it went to -23, and along with it the rx-rate also flops from 866 mbs to 24mbs!
its more apparent in the video :
Here's an un-optimized gif version in case you want to see how fast it actually flips: https://imgur.com/tJpSGFo
Is this caused by the device driver(OS related) or is a it hardware malfunction of 1.the router or 2.my wifi module(ax201)? how can I make sure which is which?
