According to the dmesg you attached, it seems that we're bouncing
between two APs:
[ 214.644607] wlp2s0: authenticate with 9c:1c:12:c1:26:82
...
[ 214.798595] wlp2s0: deauthenticated from 9c:1c:12:c1:26:82 (Reason: 3=DEAUTH_LEAVING)
...
[ 218.001901] wlp2s0: authenticate with 18:64:72:26:de:22
...
[ 218.054498] wlp2s0: deauthenticated from 18:64:72:26:de:22 (Reason: 3=DEAUTH_LEAVING)
It seems that your system is trying to connect to two different APs
forth and back. After each association succeeds, the userspace seems
to trigger a deauth (DEAUTH_LEAVING) and goes to the other AP again...
This sometimes indicates that two instances of wpa_supplicant are
competing with each other. Can you check whether you have more than
one wpa_supplicant instance running?
In any case, there seems to be a driver bug at some point, because we
get a firmware SYSASSERT. To debug that, could you follow the
directions in our debugging wiki page [1] and create a bug in bugzilla?
Please provide trace-cmd logs (as explained in the wiki) so we can try
to figure out what is going on.
One final question, was this working before you upgraded to iwlwifi
-next 5bff6536f742?
Thanks for reporting!
