Title:
Wireless network disconnections on Dell XPS 13
Status in “linux” package in Ubuntu:
Fix Released
Status in “linux” source package in Trusty:
Fix Released
Status in “linux” source package in Utopic:
Fix Released
Bug description:
SRU Justification
Impact: Many users with Intel 7260 wireless are seeing relatively
frequent disconnections as a result of the firmware reporting loss of
beacons from the access point.
Fix: Two upstream backports, one which waits for several lost beacon
reports before reporting beacon loss to mac80211, and another which
fixes a bug with mac80211's handling of beacon loss reports from some
drivers (in particular iwlwifi).
Test Case: Tested on LP#1349572.
Regression Potential: These patches were merged upstream in 3.14 and
3.15 without any reported regressions.
---
With kernel 3.13.0.30 and 22.1.7.0, there are lots of wireless disconnections.
Tested also with kernel 3.13.0.32 and 22.24.8.0 , also lots of wireles
disconnections.
The AP is an ASL-26555 from Movistar(Spain). Firmware version:
v2.0.0.51B_ESv6
Seems that when the computer is working for some time it is more easy
to reproduce this beahviour.
Added this bug as sugested in #1293569, comment #91.
