No Wireless Extensions

I'm running Linux From Scratch on my laptop, and I recently attempted to set up a Linksys WUSB11 (FCC ID: PKW-WUSB11), using the driver (at76c503a-0.10).

The driver loads properly and registers the new interface, wlan0, but iwconfig wlan0 just outputs "wlan0 no wireless extensions.", and all other iwconfig calls fail too. ifconfig correctly identifies it, however.

I read some past posts and then turned on CONFIG_NET_RADIO and CONFIG_NET_WIRELESS, recompiled my kernel and the driver, and rebooted into it.

However, /proc/net/wireless still does not exist, and the problem still occurs.
I am using version 26 of wireless_tools, hotplug 2004_03_29, and Linux 2.4.26 vanilla.

What am I doing wrong?

Chris E.

P.S. I'm going away tomorrow morning and won't be back until some time next week, so don't expect a quick response from me.

Okay, I've got /proc/net/wireless working. It turns out that I'd forgotten to boot the new kernel.
However, it still says "no wireless extensions." and an attempt to configure it gives the following message:

Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan0 ; Operation not supported.

/proc/net/wireless has the following contents:
Inter-| sta-| Quality | Discarded packets | Missed | WE
face | tus | link level noise | nwid crypt frag retry misc | beacon | 16
wlan0: 0000 0 0 0 0 0 0 0 0 0

Any ideas?

It sounds to me like the driver your using doesn't work with this card. The message your seeing from iwconfig isn't your kernel complaining about lack of wireless support, it is iwconfig saying nothing it sees is a wireless device.

Try looking at the output of lspci to find the chipset this card uses. There may be better drivers out there.
