I have experienced the same issue of not being able to change to any other mode
than Managed with my Atheros card. I get the same error as above:
sudo iwconfig ath0 mode Master
Error for wireless request "Set Mode" (8B06) :
SET failed on device ath0 ; Invalid argument
It worked perfectly in Dapper and the config I have is identical in Edgy
as I pasted the contents of the old config to the new.
This is on a clean install of Edgy using linux-restricted-
modules-2.6.17-10-generic
