Comment 6 for bug 275302

Having exactly the same problem. Internet works fine but as soon as I start a torrent client, the connections stops working after ~15min. By restarting the NetworkManager with sudo /etc/init.d/NetworkManager restart I can fix the broken connection. Though I get the same behaviour by using wicd. I have also tried to use iwconfig, but it didn't help either.
I am using RTL8187B on Intrepid under 2.6.27-11
