LMi.net DSL Troubleshooting Guide This guide will lead you through the steps in getting your DSL working again when you are unable to connect to the Internet. • Power-cycle the DSL modem and router Turning the modem off and back on causes it to re-synchronize the DSL signal and the network connection to your computer. Often, this by itself is enough to fix a DSL connection problem. To do this, unplug the power cord from the DSL modem, wait about 30 seconds, then plug it back in. Once this is done, do the same for the router. • Reboot the computer It seems trivial, but you should always begin troubleshooting computer problems by rebooting your computer! This is particularly important if your computer has worked fine in the past and only just began to exhibit problems. • Verify your TCP/IP settings If you have recently changed how your home network is setup (for example, by adding a router) or if your DSL is newly installed, check that the TCP/IP settings (your IP Address, Subnet Mask, Gateway, and DNS) are correct and match those provided in your Installation Guide.
