CM (Cable Modem) Mode provides basic home networking. In this mode, two IP stacks are active:
•
IP Stack 1 - for use by the cable company to communicate with the cable modem section
only. This stack receives its IP address from the cable company during CM initialization. It uses
the MAC address printed on the label attached to the Wireless Cable gateway.
•
IP Stack 2 - for use by you, the end user, to communicate with the cable modem and
Networking sections, to access the internal web page diagnostics and configuration. This stack
uses a fixed IP address: 192.168.100.1. It uses a MAC address of MAC label + 1 (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:B1:92.
With CM Mode, your cable company must provide one IP address for the CM section, plus one for
each PC you connect from their pool of available addresses. Your cable company may have you or
your installer manually enter these assigned addresses into your PC, or use a DHCP Server to
communicate them to your PCs, or use a method that involves you entering host names into your
PCs.
Note that in CM Mode, packets passing to the Internet to/from your PCs do not travel through
any of the IP stacks; instead they are directly bridged between the WAN and LAN sides.
