Strange networking problem with ADSL

OK, here's the deal. I have ADSL connection at home. It connects normally, and works with usual speeds, but if I run bittorrent or eMule, it sorta freezes, the speed goes to 0kB/s (upload and download) not instantly, but after a 30-60 minutes and I cannot do anything about it, but restart, or disconnect and reconnect after five or so minutes, when it works again. I have tried different network adapters, and I connected to the internet with my other computer and it worked normally, so it isn't an ISP problem. <P ID="edit"><FONT SIZE=-1><EM>Edited by roklipni on 05/30/04 05:08 PM.</EM></FONT></P>
