I am using Ubuntu 11.10 with Gnome 3 interface. The laptop is Dell XPS L502x. I am using a broadband connection(ADSL), where firstly the ethernet is connected automatically, its DNS, gateway, subnet and IP manually configured, and then a second DSL connection with a username and a password is created.
I use Deluge as my torrent client. Every time I open the torrent client and start downloading, both the two wired networks are disconnected within 5 to 10 minutes. No more wired networks are available in the network connections menu. When I restart the computer it works normally again. This happens only when downloading torrents and never anytime else, which has been verified multiple times.
Also another point is that very recently(within one week) torrent sites are supposed to have been blocked in India, but from this connection all the sites can be normally accessed and .torrent files can be downloaded. I am not sure if this has anything to do with the problem(because restarting gives it all back) but thought it would be worth mentioning. As I came home only 4 days ago, I don't know what could have happened at that time if I had used my laptop to download torrents.
Any help regarding this issue is highly appreciated.
