Strange Intel wifi trouble.
Raw
Trouble.md

The issue:

Seemingly at random the Intel wifi card fails to wakup from suspend.

I did not really figure out what happens (maybe i have the logs with answers to everything, but im not able to read it) Just a guess: race condition in powermanagment make the wifi card not to return from suspend

One of these may help:

  • turn of Wake on LAN (bios)
  • add parameters for powermanagment to the iwlwifi module (black magic, that kind which requires virgin blood)
  • turn off powermanagment via iw tool

The hard way:

Add the ifldvm and iflwifi modules to the black list, so they get unloaded on suspend and reloded on wakeup.

Qubes:

  • open terminal in sys-net
  • sudo vim /rw/config/suspend-module-blacklist
  • add iwldvm and iwlwifi
