About the CG814M Gateway

The NETGEAR CG814M Wireless Cable Modem Gateway connects directly to the wide area network (WAN) using its built-in cable modem. It has multiple options to connect to your local area network (LAN), including a 4-port 10/100 Mbps Ethernet switch, a USB port and an 802.11b wireless Access Point.

The CG814M Gateway provides highly reliable Internet access for up to 253 users.
