I'm running Debian Lenny on a Toshiba Satellite A200.

It has a builtin Atheros AR242x 802.11abg Wireless PCI express adapter.

The modules that are automatically loaded to drive this are:

ath ath5k

When using kernel 2.6.32 in a wireless hotspot /proc/net/wireless does not even exist. When using kernel 2.6.24 it exists but has no entries.

I don't know where to go to from here. Can anyone help? (The WIFI switch at bottom of notebook is on).

When I type


I get the error:

No wireless extensions.

Mind if I ask what you need /proc/net/wireless for? Is it trying to be accessed by a program like NetworkManager, or wicd?

I assume that any configuration tool would need to read from /proc/net/wireless. Am I wrong?

I've added a comment to my original question.

Does the ath5k module load for sure? Does "lsmod | grep ath" yield any output? If not, try running "modprobe ath5k".

Yes. Modules ath and ath5k load at bootup.

I'm going to try compiling ath9k. I don't know why I didn't do both in the first place. The debian wiki says ath5k for AR242 chipset and ath9k for 802.11n chipsets. lspci gives me AR242x 802.11abc. 802.11 is a protocol, not a chipset isn't it? I hate hardware issues!

I'm also going to try madwifi-tools.

Yes, you're correct: 802.11 is the protocol. Your chipset being "AR242x". :) Have you checked to make sure the module isn't blacklisted anywhere?

Look at the Debian Wiki page for that type of card. I'm sure you'll find it very useful.

Thanks for that. I've already seen that page but the HowToUse page has highlighted the step that doesn't work. I've added that to my original question.
