Actiontec Troubleshooting: The DSL light is off
Actiontec GT704WG Troubleshooting: The DSL light is off
Verify that your phone line connection to the DSL port of the router is secure.
Check the connection where your phone line connects to your wall outlet.
If the light is still off, verify that a DSL filter is installed between all telephone equipment and the telephone line. The Line side of the DSL filter should be connected to the telephone line, while the Phone side of the DSL filter should be connected to the telephone equipment.
Note: DSL filters are not required if you have Verizon 7M High Speed Internet service.
If the light is still off, verify that the DSL router connects to the telephone line without a DSL filter.
If the DSL light is now illuminated but you can't connect to the Internet, continue with Troubleshooting Step 4.
