RE: The default OS / kernel had a wifi issue? - bcnaz - 11-14-2019 *** .My first wifi "DROP" !!! I have been on for about an hour - but FireFox crashed for the first time also.. ? Maybe one caused the other or one thing caused both problems at the same time ? But the wifi reconnected automatically and I just restarted FireFox.

I have not read much about the wifi issues. Perhaps that was discussed before? I see wifi dying under high cpu load (which probably boils down to overheating). Perhaps your laptop is always overheating for a reason TBD? What do your temp sensors read? In idle it should be around 45C (at least on my machine) $ cat /sys/class/thermal/thermal_zone?/temp 46250 45625 18800 When I stress the CPU with a parallel build, the temperature goes up to close to 70C and some time later, wifi shuts down. RE: The default OS / kernel had a wifi issue? - Arwen - 11-14-2019 I've been thinking about this, (though not experienced the issue my self). How about checking the antenna connection? - Perhaps it's slightly loose, and heat causes it to get further loose. When the board cools down, the connector works better. - Or maybe a cold solder joint, (which works sort of). When things heat up it could get better worse depending on it's exact location. Let us know what you find. RE: The default OS / kernel had a wifi issue? - Mrfixit2001 - 11-23-2019 Issue was determined to be the wifi power management. The update that was just pushed, v1.5, will disable wifi power management after a reboot, which should resolve this issue RE: The default OS / kernel had a wifi issue? - Arwen - 11-23-2019 (11-23-2019, 03:58 PM)Mrfixit2001 Wrote: Issue was determined to be the wifi power management.

RE: The default OS / kernel had a wifi issue? - lowry - 03-02-2020 Commenting out `iwconfig wlan0 power off` in `/etc/rc.local` solves the problem of wifi disconnects under load. Running the default Debian, executed `mrfixit_update.sh` a few hours before. |
