Broadband and Bellwire it might help you sort out problems with your ADSL broadband. Personally I prefer the original method of using an ADSL master socket like this which gives the same results as the link says but without the ugly microfilters dangling out of your phone sockets being kicked by the kids etc.
After reading that link you might at least want to try removing the front from your master socket and plugging straight into the line socket behind it as the link explains. Then you will find out if you can get faster speeds.
