Laptop Wireless Signal Dropping
I have dell XPS laptop and recently installed/Upgraded to UBUNTU 11.
After installing new upgrade version i found problem connecting to Wireless network after a connection established.
Initially when I start my laptop it gets connected and after like 1-2 hours, Wireless connection Automatically disconnects and won't get connected, even after giving correct password etc.
I don't have this problem with previous Ubuntu version (10.0), only see with this version 11.0.
Can someone tell me if any one have the same problem. Thanks for help.
