[Bug 1315221] Re: 8086:08b1 (rev 6b) [Dell XPS 13 9333] iwlwifi regularly loses connection/becomes unusable on Intel 7260
Antonio Cañas Vargas, as far as Ubuntu is concerned, WORKAROUNDs, hacks, etc. does not solve a bug as outlined in https://wiki.ubuntu.com/Bugs/Status . So your hardware and problem may be tracked, could you please file a new report with Ubuntu by executing the following in a terminal while booted into the default Ubuntu kernel (not a mainline one) via:
ubuntu-bug linux
For more on this, please read the official Ubuntu documentation:
Ubuntu Bug Control and Ubuntu Bug Squad: https://wiki.ubuntu.com/Bugs/BestPractices#X.2BAC8-Reporting.Focus_on_One_Issue
Ubuntu Kernel Team: https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies#Filing_Kernel_Bug_reports
Ubuntu Community: https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
When opening up the new report, please feel free to subscribe me to it.
As well, please do not announce in this report you created a new bug
report.
Thank you for your understanding.

Title:
8086:08b1 (rev 6b) [Dell XPS 13 9333] iwlwifi regularly loses
connection/becomes unusable on Intel 7260
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
My Intel 7260 network card regularly shows very poor performance
and/or loses its connection entirely. On several occasions I have been
unable to reestablish an association with the AP without rebooting.
This occurs even if the laptop is within a few feet of the AP. I did
not have this problem on 12.04 with a quantal backport kernel.
