Public bug reported:
Running 14.04 (beta) with Kernel 3.13.0-17-generic
I've encountered a strange and reproducible error with the
iwlwifi-7260-8.ucode firmware.
This laptop is a Dell XPS 12 (haswell). With the -8 firmware, it will
connect fine to wifi for 30 or 40 mins at a time, then will start
dropping connections repeatedly. Even modprobe -r unloading and
reloading doesn't fix the issue, only a reboot will temporarily solve it
for 40 mins at a time.
Moreover, here is what's strange, is during these episodes of
disconnection it seems to affect the actual router (2Wire), as the other
devices in the house will also start to have issues (very slow
connections, limited range,etc). Once I reboot this laptop everything
and all devices will return to normal.
This issue has been fixed by me manually removing the -8 firware from
/lib/firmware and letting the -7 firmware load instead. Since that has
been done there has not been a single issue of this happening (now going
on 4 days).
let me know if there is any other information you would like me to
provide.
