Connect the Modem
Turn off your computer.
Place one end of the Ethernet cable into your computer’s Ethernet port and the other end into the modem’s yellow LAN (local area network) port.
Put the dual-jack adapter into the closest telephone jack. Place one end of the gray telephone cord into either side of the adapter and the other into your modem’s gray DSL port.
Plug the power cord into the modem and an electrical outlet and power up the modem.
Plug your telephone into the modem by placing a DSL filter into the open side of the adapter. Plug the telephone into the filter.
Remove the telephone cord from its jack and plug in a DSL filter. Put the telephone cord into the filter and listen for a dial tone.
Repeat this step to install DSL filters in all other telephone jacks.
