2.3 Connecting the Router
Before you start, turn o your modem, if any, and remove the backup battery if it has
one. Then place the router horizontally and orient the antennas vertically.
Note: If you already have a router and want to congure this new router as an access point to extend your network, refer to
Set Up the Router in Access Point Mode.
Follow the steps below to connect your router.
If your Internet connection is through an Ethernet cable from the wall instead of
through a DSL/Cable/Satellite modem, connect the Ethernet cable directly to the
router’s Internet port, then follow steps 4 and 5 to complete the hardware connection.
1. Turn o the modem and remove the backup battery if it has one.
2. Connect the modem to the WAN port on your router with an Ethernet cable.
3. Turn on the modem, and then wait about 2 minutes for it to restart.
