[GRLUG] Ubuntu and Wireless

[Godwin]

Well... just 'cause a module/driver loaded doesn't necessarily mean
your card is ready or even visible.  What does "/sbin/ifconfig" show?
Or even "iwlist" or "iwconfig"?

godwin at birdofpray:~$ iw [TAB]
iwconfig  iwevent   iwgetid   iwlist    iwpriv    iwspy

godwin at birdofpray:~$ iwconfig
lo        no wireless extensions.
eth0      no wireless extensions.
sit0      no wireless extensions.
ham0      no wireless extensions.

godwin at birdofpray:~$
