I have an old laptop (Thinkpad T30) and I have installed lubuntu 10.04 on it. NetworkManager could see the available wifi but the bottom was gray out. It seems that it is an unsolved-bug in wifi and the only solution was replacing it with lovely wicd.

So, I have installed the latest wicd, and I got happy that I could have see the available wifi and possible access. but whenever I ask wicd to connect me to that, after quite few seconds, an error appear that : "Connection Failed: Unable to get IP address".

I googled the error; some people have suggested downgrading wifi, and some others were suggesting installing some drivers. and non of them worked. I also tried this "http://www.backtrack-linux.org/forums/showthread.php?t=48658".

I appreciate any comments that can help me to make my wifi into work. either for troubleshooting the current "wicd" and this error, or installing other alternatives that I am not aware of.

I assume the problem is somewhere between dhcp* and wicd but I am not sure how to track and solve it.

[34.744120] eth1: no IPv6 routers present

Your AIRONET Wireless Communications Cisco Aironet Wireless 802.11b is probably not getting an IP address from the router as most networks are set to use WPA or, more preferrably WPA2 encryption. As well, some routers are set to use 802.11G and N only.

Many older wireless devices were built before WPA, WPA2 and 802.11G and N were developed. Check to see the capabilities of your device. In a terminal:

iwconfig

Your wirless device may be eth1 or possibly wlan0. Find its capabilities:

sudo iwlist eth1 auth

Of course, substitute wlan0 if your wireless interface is not eth1. Are WPA and WPA2 listed as capabilities of your wireless device?

I cannot recommend that you reset the router to use WEP encryption, which your Aironet may connect with easily, because it is quite insecure.

Please confirm the driver you are using is airo:

lsmod

Check the message logs for any troubleshooting clues:

dmesg | grep -e eth1 -e airo
