Unique Wifi issue

Asked by sanket4005 on 2012-07-12

I have a dell studio 1558 laptop. It has Ubuntu 12.04 installed and that's the only OS present on my laptop. My default wifi connection icon on the panel just says "device not ready". I am able to access wifi via wicd network manager. It works well with my laptop when the battery charger is plugged in. As and when i detach the charger, the connection is automatically lost and i am unable to access the Internet. The wicd network manager remains stuck on the "obtaining IP" position, and ultimately fails to connect. But it is able to connect when i connect my battery charger.
Please guide me..

If you run:

echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf > /dev/null

Is it ok?
