Have you tried going to your router's setup page and forwarding your ports? I have to enter a series of numbers (should be in your router's manual) in my browser's address bar to access this page. Then you will be asked for a password. If you have not set the password to something specific, it will be the default password (should be in your manual). Enter the password, then look around the setup page for port forwarding and forward a port(s) above 50,000. The default ports for BT (6881-6889) are now known to be used for BT by ISP's so they throttle or limit them. Also use a client with encryption; this also fights ISP throttling/limiting . I use BitTornado 3.18. You can also assign a permanent internal IP address (not the WAN or external IP address assigned by your ISP) for each of your computers so they don't flip/switch addresses everytime you power down. Go to Control Panel > Network Connections > settings? > use the router's setup page address plus a unique # for each of your computers. I forget exactly how to do this, but you can forward the ports on one or both computers by entering the address you assign each computer on the router's setup page. Last thing, make sure Windows firewall is not blocking your BT client. Go to Control Panel > Windows Firewall > Exceptions. Make sure your BT client is in the list and that the box is checked. Hope this helps, but I use cable, not DSL.
