iwconfig gives ath0: no such device

[josh at offthehill.org (Josh ChaitinPollak)]

I was just looking at the MadWifi compatibility list, and according  
to that page the WG511T are Atheros. Netgear seems to have a habit of  
changing chipsets without changing model #'s though, so perhaps there  
is a new revision that isn't Atheros.

If you have a wlan0 but no ath0, you need to create one (excerpt from  
http://madwifi.org/wiki/UserDocs/FirstTimeHowTo ):
Creating an Interface

MADWiFi supports virtual access points, which means you can create  
more than one wireless device per wireless card. By default, a sta  
mode VAP is created by, which is MadWifi talk for a 'managed mode  
wireless interface'.

If your svn snapshot is more recent than the 23rd January 2006,  
(r1407) than you can skip the following step:

If not, then follow these instructions to make a normal station mode  
interface. Type (as root):

wlanconfig ath0 create wlandev wifi0 wlanmode sta
Now, if you type iwconfig, you should see a list like the following:

eth0      no wireless extensions.

lo        no wireless extensions.

wifi0     no wireless extensions.
