[Bug 1273392] Re: 0cf3:9271 [MSI FM2-A75IA-E53] ath9k_htc: AR9271 wireless device stops functioning

 

This is what I got from iw dev wlan0 scan dump (selecting only my AP):

I've just now disabled WPS on the AP. I wasn't using it anyway. I
presume this is G, as only G modes are listed.

I'll try to apply this patch to linux-image-3.13.0-5-generic, keep using
that in saucy with nohwcrypt=1 and see what gives.

(about USB behaving crappily: meh)

Title:
  0cf3:9271 [MSI FM2-A75IA-E53] ath9k_htc: AR9271 wireless device stops
  functioning

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  A long time after a cold boot, my wireless connection starts dropping,
  will try to reconnect but will not come back again. When I'm in that
  state only a suspend, waiting a while and resuming gets my wireless
  connection back again.  However, after that state it does not take
  long before it starts to drop again.

  WORKAROUND: I could not reproduce this problem again after setting
  nohwcrypt=1 on the ath9k_htc module.
