Having blacklisted ath9k and added ath_pci to /etc/modules, I've not
experienced the problem.

** Summary changed:

- [ath9k] Wireles connection stops after 10 minutes
+ [ath9k] Wireless connection stops after 10 minutes

** Description changed:

- Binary package hint: network-manager
+ Since the addition of ath9k to the kernel, wireless stops working about
+ every 10 minutes or so.
  
- Since the latest lot of updates, my wireless connection times out after
- 10 minutes or so. There's nothing of note in dmesg or messages, I get
- the following from --no-daemon at the point of it stopping.
- 
- NetworkManager: <info>  (wlan0): supplicant connection state change: 7
- -> 6
- 
- (NetworkManager:309): GLib-GObject-CRITICAL **: g_object_unref: assertion

- NetworkManager: <WARN>  check_one_route(): (wlan0) error -34 returned from

+ EDIT: removing ath9k and loading ath_pci seems to solve this problem
