This has happened to me in the > past. Now, I've made 2 changes so I'm not sure which affected it: 1. I replaced the card with an AR9285 ath0@pci0:1:0:0: class=0x028000 card=0x7167144f chip=0x002b168c rev=0x01 hdr=0x00 vendor = 'Atheros Communications Inc.' device = 'Atheros AR9285 Wireless LAN 802.11 a/b/g/n Controller (AR928x)' class = network 2. I changed the channel on our AP. (there were 2 other nearby APs on the same channel). I noticed that I got a lot more bb hangs at the office compared to home - there are a lot more APs nearby: [mini] /usr/home/ianf $ ifconfig wlan0 scan SSID/MESH ID BSSID CHAN RATE S:N INT CAPS Ignition 00:26:bb:78:b4:91 6 54M -89:-96 100 EPS RSN HTCAP WPA WME Eco Impact 00:22:3f:55:80:bc 11 54M -92:-96 100 EP HTCAP WPS WPA WME Viic 00:14:6c:49:3f:1c 11 54M -92:-96 100 EPS WPA ATH WME cluelan 00:30:4f:58:bf:96 7 54M -72:-96 100 EPS WPA ATH WME PRIVATE LABEL 00:19:70:05:28:c4 3 54M -79:-96 100 EP WPA WME blinkbroom1 00:18:4d:1c:8e:3a 5 54M -89:-96 100 EPS WPA Sasman 00:26:f2:46:2c:de 1 54M -93:-96 100 EP WME cocoa 00:26:f2:3d:aa:13 3 54M -94:-96 200 EPS WME HTCAP ATH CareCross 30:46:9a:1e:b0:ca 8 54M -35:-96 100 EPS RSN WPA We're "cluelan" and we were on channel 3. Previously, I was seeing a hang every 10 minutes or so, since changing the channel to a "free" one, I haven't had a hang in the last 40 minutes. The only bb hang I've had was when I deactivated the RF switch on netbook and that was a semi-expected result. Ian -- Ian Freislich
