Note: Prior to connecting the router, be sure to power off your computer, DSL/Cable
modem, and the router. You should setup the router with a wired connection first before
attempting to setup any wireless connection.
Step 1 Connect one end of a network cable to the Internet port of the router and
connect the other end of the cable to the DSL/Cable modem.
Step 2 With another network cable, connect one end of the cable to your computer’s
network card and connect the other end to one of the LAN ports of the router.
Step 3 Power on the DSL/Cable modem and wait for the lights on the modem to settle
down.
Step 4 Power on the router by connecting one end of the supplied power adapter to the
power jack of the router and connecting the other end to an electrical outlet.
Step 5 Power on your computer.
