[Bug 1315221] Re: 8086:08b1 (rev 6b) [Dell XPS 13 9333] iwlwifi regularly loses connection/becomes unusable on Intel 7260

 

hello,

sorry for the basic question...

during the last update the application "Software Updater" reported me a
wrong package installation. the package is related to the wifi-bluetooth
of the intel chipset we are talking about in this discussion. however,
i'm not able to find any more the log concerning that package. Running
the software does not provide any usefull information but simply
reporting what shown in the snapshot attached.

where can i find it?

thank
g.

Title:
  8086:08b1 (rev 6b) [Dell XPS 13 9333] iwlwifi regularly loses
  connection/becomes unusable on Intel 7260

Status in linux package in Ubuntu:
  Incomplete

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.

  Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b1] (rev 6b)
