  iwlwifi 7260 loses connection, performance degrades

Status in linux package in Ubuntu:

Bug description:

  I have a Sony Vaio Pro 11 which has a intel 7260 wifi chip. I've had
  nothing but trouble with it (and from reading forums, I'm not alone).
  I file this bug to help fix issues.

  My findings with recent kernels: laptop has Ubuntu Vivid installed,
  which comes with the 3.18 kernel and 23.11.10 firmware. With the -10
  firmware, often the wifi doesn't even associate with the access point,
  while all other devices in the house can. When it does connect, the
  speed is fast for about 1 second (around 10 MB/s), en then drops to
  20-60 kbps, or loses connection altogether. With self-compiled
  3.19-rc6 (with latest iwlwifi-fixes merged) it's the same. I tried the
  23.12.10 firmware, but it is the same.

  When I switch to the 25.228.9 firmware, it is much better, however,
  speed still drops every now and then, but much less than with the -10
  firmware. Kernel version doesn't seem to matter much, firmware version
  seems to drive all variability.

  This problem is for both bands 2.4 GHz and 5 GHz.

  I can provide all debugging info you request. I will provide the
  minimum logging tonight when I get home.
