Before 5 months I bought a laptop Inspiron N5110 with Intel Centrino Wireless-N 1030 bluetooth card. So since then I have one very annoying problem. I've searched in Google before but with no results because noone has exactly my problem. The problem is that my internet connection stops, I disconnect from Skype and can't surf in internet. In the right bottom angle of the screen where is the signal strenght indicator appears ! sign in yellow triangle. When I troubleshoot it fixes the connection for a few minutes and says "Deafault gateway not found". And here is the unique thing in my problem-it happens when I start a torrent client. Every time when I have to download something I stay non-stop on the computer and reset the dying internet connection every two minutes.

Please help me because I'm very miserable and become to lose hope and will!
