Well the error meesage is fine (the driver doesn't support the
'monitor mode' and hence the cryptic message. I get the following:

[asterix]: ifup ath0
Error for wireless request "Set Mode" (8B06) :
    SET failed on device ath0 ; Invalid argument.
Cannot get driver information: Operation not supported

Determining IP information for ath0... done.

I would check if the encryption key is specified correctly (and
perhaps try it on an un-encrypted network as well). Also, I use the
cvs version of the driver - not the august release version - and
compiled with 'make CC=gcc32'.

The following work for me:

802.11b no enc
802.11b 40bit enc
802.11a no enc

Some things to try:

iwlist ath0 scan     # lists access points that are arround.
iwpriv ath0 mode 2   # force the card into 802.11b mode
iwpriv ath0 mode 20  # reset the mode to auto

Also, some have noted that Ad-Hoc mode has some issues. I haven't
tried this mode.
