I can confirm I'm having the same issues on a Macbook Pro 2,2 , which has a wireless card with the exact same chipset (AR5008). I can confirm also that I'm having the same problem described in this bug report: https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/278190 Relevant output from lspci: 03:00.0 Network controller: Atheros Communications Inc. AR5008 Wireless Network Adapter (rev 01) Relevant output from modinfo ath9k: filename: /lib/modules/2.6.27-9-generic/kernel/drivers/net/wireless/ath9k/ath9k.ko srcversion: 5307204F68EC6FC867B1E91 depends: mac80211 vermagic: 2.6.27-9-generic SMP mod_unload modversions 586 As the other bug report doesn't relate to this hardware, I'll just report here my findings. I was having intermittent disconnections so I thought I'd try the workaround proposed for bug #278190: turning off encryption, but my ISP (which controls the router) won't let me have an open access point, so I just changed the encryption from WPA(TKIP+AES) to WPA(TKIP) and since then I haven't had any disconnections.
