Toufik, can you please upload or send me the updated firmware? I have the same problems, but there is no newer iwlwifi release (last release is from august).
I'm not able to compile the current code :(
Thanks a lot!

Title:
  8086:08b1 iwlwifi crash with "Microcode SW error detected"

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  I have an intel 7260 wifi card (it is a dual band). I have had a **lot** of trouble connecting to my router (also dual band). I don't know how I did but I managed to connect to the 2.4GHz AP but it is not very stable. However, I've never managed to connect to the 5.5GHz AP while it is listed as available. By looking at dmesg, the driver is crashing:
  ...
  [   74.358662] wlan0: authenticate with a6:b1:e9:ae:61:a2
  [   74.359848] wlan0: send auth to a6:b1:e9:ae:61:a2 (try 1/3)
  [   74.360756] wlan0: authenticated
  [   74.364053] wlan0: associate with a6:b1:e9:ae:61:a2 (try 1/3)
  [   74.373879] iwlwifi 0000:01:00.0: Microcode SW error detected.  Restarting 0x2000000.
  ...

  Then the wifi is dead and I have to reboot.
