Public bug reported:
Recently installed xenial on a Lenovo Yoga 2-13 (Intel 7260 wifi card).
On wily it worked perfectly, on xenial it regularly appears to restart
the wifi connection (the end result is that I lose any vpn connections,
as they don't seem to notice the restart, but that's another issue).
In general use, I get periodic "wlp1s0: WPA: Group rekeying completed"
messages in syslog (and used to get these in wily, too), but now, after
a random amount of time (over the weekend it was several hours, this
morning it was about 10 minutes, so it might be related to the amount of
network traffic) I get "kernel: [13983.248157] wlp1s0: authenticate with
00:8a:ae:c9:9a:d8" (presumably my wifi router) and the usual wifi
startup stuff including frequency lists, etc.
It also always logs "systemd-udevd[30319]: Process '/sbin/crda' failed
with exit code 249." every time (I'm not sure if this is relevant)
After reading old, but similar bug reports, I've tried changing some of
the module options: "11n_disable=1" and "11n_disable=8", but these had
no effect. I've also tried the older firmware that wily used
(/lib/firmware/iwlwifi-7260-13.ucode), but again, no improvement.
