I have a very old laptop I was thinking of installing Ubuntu 10.10 on. The install went smoothly. Everything seems to be working well except the wireless connection. When I click on the wireless icon on the top right, it shows me a list of networks available. I have tried joining open networks, WEP, WPA and WPA2 networks - all of which fail. I know the password is working because I tested it on my macbook sitting alongside the old laptop.

The wireless adapter in question is supposed to work "out of the box" with Ubuntu, still I'm having problems.

Here are the details of the old laptop:

1.1) Brand:
Neo (a phillippine-based company)

1.2) Model number:
SZS223 (discontinued)

2 ) Wireless Brand, Model and Wireless Chipset:
Intel corporation PRO/Wireless 2200BG [Calexico2] (rev 05)

3 ) check interface:
Code:
$iwconfig

lo        no wireless extensions.
