After installing 8.10 on my AAO, I've had (almost) no end of wireless troubles. These have generally consisted of either the adapter not being recognised by the OS at all (other than in lspci), or being recognised and failing to deal with my WPA2 WLAN. Currently, we're on the former situation.
I have followed all manner of tips and guides to resolve this, to no avail. The backports modules are installed, and I've previously tried the madwifi drivers. ath_pci and ath_hal are blacklisted. I've updated and upgraded via apt today.

There are also some interesting bits from dmesg that only appear when the adapter is recognised (but can't connect) - I'll post those next time that happens.
The first odd thing (that I've noticed) is from lspci - ath5k_pci appears to be the driver in use as opposed to plain old ath5k. Is this normal?
The wired network connection is fine, so the network stack itself seems to be alright, but I'd really love to get the wireless working and in a reliable fashion.
