** Description changed:

- Last day I had very slow connectivity with my ath9k card. This was
- (temporarily) solved by setting nohwcrypt=1 module option, but today,
- after some use and some non-use (perhaps it got in a different ACPI
- state) all I could get was connect/disconnect/connect/disconnect series.
+ I had very slow wifi connectivity from my computer to my "Freebox v5"
+ (french operator Free) running OS details: Chumby Internet radio, Linux
+ 2.6.13 - 2.6.28, Linux 2.6.18 (nmap scan) . This was (temporarily)
+ solved by setting nohwcrypt=1 module option, but today, after some use
+ and some non-use (perhaps it got in a different ACPI state) all I could
+ get was connect/disconnect/connect/disconnect series.
  
  The worst part of it is that it seems to authenticate, but it gets
  nothing in /etc/resolv.conf, and gives "network is unreachable" if I try
  to ping 192.168.0.0/24.
  
  I also tried to use backports modules and disable power management, to
  no success.
  
+ WORKAROUND: In Precise, used linux-backports-modules-cw-3.3-precise-
+ generic provided the network runs WPA+AES.
