network help needed...urgently!!!

[047]

Hi...

I own a tataindicom broadband internet. when i use it on my HP Probook 4520s my internet connection gets log out after 1 min of logging in everytime... while same connection works properly on other laptop and desktop. as soon as i connect the network through my probook (using either WIRELESS or WIRED), connection gets log out on every other system including probook.

so to use the broadband i have to disconnect my probook from the network...

can anybody pls help me....its urgent...thnx
