Failure to SET Mode of wlan0 in F7

[Simon Slater]

	G'day again,
		I've been working at getting wireless going on an Acer Extensa 5220
with a Broadcom 1390 WLAN Mini-PCI Card.  The error that appears isn't
covered in the threads and howto's on the Broadcom cards so perhaps it
is a simple networking mistake on my part.

	Both the commands #ifup wlan0 or #iwconfig wlan0 mode Auto give the
error:

Error for wireless request "Set Mode" (8B06) :
	SET failed on device wlan0 ; Invalid argument.

	I have tried Auto and AdHoc modes in both system-config-network and
iwconfig with the same error.  The network service is off, Network
Manager & NM Dispatcher are on.  The NM applet shows up to 3 wireless
networks but I cannot connect.  ifconfig shows wlan0 is UP.

	What have I missed, skipped or forgotten?
