uses the MAC address printed on the label attached to the Wireless Cable Gateway.

•IP Stack 3 - for use by you to remotely (i.e. from somewhere on the WAN side, such as at

your remote workplace) communicate with the Cable Modem and Networking sections, to

remotely access the internal web page diagnostics and configuration. This stack is also

used by your cable company to deliver packets between the Internet and the gateway’s

networking section so they can be routed to/from your PCs. This stack requires an IP

address assigned by the cable company from their pool of available addresses. Your cable

company may have you or your installer manually enter assigned addresses into your

gateway, or use a DHCP Server to communicate them, or use a method that involves you

entering host names. This stack uses a MAC address of MAC label + 2 (the MAC label is

found on the bottom of the unit). E.g., if the MAC address is 00:90:64:12:B1:91, this MAC

address would be 00:90:64:12:B1:93.

•IP Stack 5 - for use by you to locally (i.e. from somewhere on the LAN side in your home)

communicate with the Cable Modem and Networking sections, to access the internal web

page diagnostics and configuration. This stack is also used by the gateway’s networking

section to route packets between the gateway’s Networking section and your PCs. This

stack uses a fixed IP address: 192.168.0.1. It uses a MAC address of MAC label + 4 (the

MAC label is found on the bottom of the unit). E.g., if the MAC address is

00:90:64:12:B1:91, this MAC address would be 00:90:64:12:B1:95.
