Trying to get a Toshiba Satellite L40 work with 64 bit Xubuntu 12.10, kernel 3.5.0-21.

Wired internet connection runs well, and all updates have been applied. The problem is the wirefree connection through the Atheros card.

lspci -vnn gives

    Capabilities: <access denied>
    Kernel driver in use: ath5k
    Kernel modules: ath5k
and rfkill list all gives
Code:

Searching seems to indicate that the Askey cards have been known to cause problems in older releases. Is there a solution for 12.10?
