If you have not already done so, open the web-based utility as described in "Opening the WebBased Modem Management Utility" on page 2-4. Check the LAN IP address of your router, which is usually printed on a label on the bottom or at the rear of the device. Note how the address is comprised of four numbers separated by period characters. If necessary, change the LAN IP address of the modem so that the two leftmost numbers of the address are the same as the two left-most numbers of the router's LAN IP address, and the third number in the modem's address is different from the third number in the router's address. For example, if the router's LAN IP address is the same as the modem's default address (192. 168. 0. 1), change the LAN IP address of the modem to 192. 168. 1. 1. Tip: If you change the LAN IP address of the modem, write the new address on a sticky label and attach it to the bottom of the unit.
