Hey, Followed your steps and still seeing the problem, but in case this is a clue:
My wifi seemed to be working normally at first. After about two minutes of ping acting normally and browsing I tried doing `sudo service network-manager restart` to see if the problem came back and it indeed returned right away. You can see where I ran the restart command in the timestamps in the attached dmesg output. -Max On Sun, Apr 5, 2020, at 12:42 PM, You-Sheng Yang wrote: > It seems you're suffering from wifi firmware crash and the hardware is > resetting itself occasionally.
