Hi

I just installed ubuntu 10.10 on my laptop Dell Inspiron 1525. Wireless internet is not working. I installed wicd network manager and I am able to see the available wireless networks. My wireless connection is encrypted. I have tried all encrypted options with the key but no avail. It says "Cannot obtain an IP address" after validating authentication. Kindly help.

Where is it trying to get the IP address from? Is it a local DHCP server or do you just have one connection to an ISP?

Is there a MAC filter on your router?

Thanks for the replies. I am connecting to ADSL wireless broadband Thomson speed touch modem. I do not know how but after switching over and over from wired to wireless it eventually started working - weird.
