[Bug 1808389] Re: iwlwifi Intel 8265 firmware crashing on lenovo x1 Gen 6

2019-11-05 Thread Illi
Ok, this is a complex matter. I just experienced this unpleasant feature
on my laptop using the above described driver and hardware for the last
two days. =>It seems to be a radio transmission issue.<=

The Linux driver as well as the microcode of the WiFi device must be
able to cope with the small frequency jumps of the access point. Yes,
frequencies are =>NOT<= very stable. This is shown in the logs by the
following messages: wpa_supplicant[971]: wlp1s0: CTRL-EVENT-SIGNAL-
CHANGE. When this event occurs, your hardware must resync with the
access point. The driver as well as the microcode of your WiFi device
may or may not support such a frequency jump. In other term they may or
may not be able to cope with the noise. The following log message shows
that my system was not able to cope with it: iwlwifi :01:00.0:
Microcode SW error detected.

What actually solved the issue is re-configuring the access point. I
limited the channel width on the 2.4 Ghz frequency to 20 Mhz to avoid
interference with other access points in the area. In addition I defined
a precise channel for the access. For the channel selection, prefer
channel 1, 6 or 11, since they do not overlap. Now my connection is
stable and my logs are clean.

For the 5 Ghz network, these problem might not occur as frequently as on
the 2.4 Ghz one, since it is less used. In case similar issues are
faced, proceed similarly.

Hope it helps, Illi
