Hello,

I've installed Madwifi as described in this post (http://www.ubuntugeek.com/new-madwifi-now-supports-ar2425-in-madwifi-trunk-branch.html). I got it to list the available wireless networks, but it won't connect to any of them. Why's that?

I also forgot to mention that Wicd lists the wireless networks only on boot, then they disappear when I hit refresh. Also, when I do

iwlist scanning

I get that there are no available wireless connections found, although Wicd lists some. After I choose one from Wicd, it doesn't connect at all.

I really have no idea what to do.

So, the problem persists. I removed madwifi and installed ndiswrapper. The output is as follows:

iwconfig


lo no wireless extensions.

eth0 no wireless extensions.

iwlist scanning


lo Interface doesn't support scanning.

eth0 Interface doesn't support scanning.

wlan0 No scan results

This is funny, because Wicd clearly shows, that there ARE wireless connections in range, both secured and unsecured. The problem is that I can't connect to either of them. It sticks at "Obtaining IP address..." and that's it. Then, when I try to scan once more via Wicd all wireless connections disappear from the list.

Could this be a hardware problem?!
