Home Forums Networks & Cross-Platform Networking Making DSL Faster

Also -- the presence of other devices on the same phone line as the DSL can dramatically affect the performance of DSL. One example -- security systems that have a connection to the phone line for contacting a central security monitoring station (we have one of these in our home) are notorious for adding noise to phone lines. Other devices (such as faxes or other voice phone, especially wireless ones) might add noise. The only way to tell is to disconnect them all and test, and then reconnect one at a time until the noise returns. If there is a security system, that might be hard to disconnect -- ours for instance is hard wired in.
