[Bug 1264384] Re: 8086:08b2 [Lenovo ThinkPad S3-S440] Wireless Intel 7260 (rev. 73) unstable

 

New informations about my testing:
a) with new firmware the wifi connection is rock-stable at office (more than 5 hours without problem)
b) at home i have changed wifi router to newer, problem is the same, tested under stable kerner and mainline (3.13.0-031300rc6-generic). sorry for long time to answer about my testing under 3.13.0-031300rc6-generic, but under this kernel my graphic card stopped working (new Intel/AMD double cards is not working out of the box in ubuntu). I'm plannig to test at home this card in windows again (if there is a big difference, or only card is lower quality than my other devices)

Title:
  8086:08b2 [Lenovo ThinkPad S3-S440] Wireless  Intel 7260 (rev. 73)
  unstable

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  wireless card is not working properly in linux. card is crashing with firmware installed by 13.10 Ubuntu.
  after firmware upgrade to 22.1.7.0 (iwlwifi) it's much better and problems occurs only when:
  a) too much AP's around me (in office)
  b) >5 meter away from home AP (signal strength is low, in Win8 works perfectly)
  wifi reconnects again every minute or two.
  interesting info: when the network usage is higer (video streaming), wifi is reconnecting only every 5 minutes.
