Thinkpad X1 Carbon strange wifi behavior

Post by pusiux » Thu Feb 01, 2018 3:44 pm


I have problem with wifi connection on my laptop. Few days ago I got this thinkpad and installed newest mint.
I observed strange behaviors First was problem with speed. I observed that sometimes I have speed around 1Mbps, when it should be about 20Mbps(checed on
Now when I am watching youtube or downloading something I got internet crash. On speedtest I see that i have speed 20Mbps for 1 sec i then it is going to 0 and I got download error. I don't know if this is problem with my drivers or sth or maybe wifi adapter is dead.

iwconfig output:
