Thanks, Adrian as requested. output of dmesg after a timeout, then me setting the sysctl http://unsane.co.uk/ath-timeout-dmesg.txt output after i then ran ifconfig wlan0 scan http://unsane.co.uk/ath-timeout-dmesg-with-scan.txt Please note that it hung twice in these dmesg, the first time I didnt see it until after it had recovered, I then ran sysctl dev.ath.0.txagg=1 but not the scan as it hung again shortly after (passing much traffic will do it it seems.) On the second hang I set the sysctl before the network connection came back, then ran ifconfig wlan0 scan. Output of the scan is SSID/MESH ID BSSID CHAN RATE S:N INT CAPS Radford_Net... 00:19:e0:a1:2f:f8 6 54M -93:-96 100 EPS RSN WPA ATH BTHomeHub2-... 00:21:04:c2:d6:c2 11 54M -93:-96 100 EPS RSN WPA WME HTCAP O2wireless9... 00:24:17:97:84:31 3 54M -92:-96 100 EP RSN virginmedia... a0:21:b7:e3:5b:89 5 54M -92:-96 100 EP RSN HTCAP WPS WPA WME vhoff e0:91:f5:48:5b:b9 5 54M -77:-96 100 EPS RSN WPA WME HTCAP ATH WPS Seems someone has switched channels to be on the same as me again :( ath and ath_pci complied into the kernel.
