Troubleshooting

You can correct most problems you have with your product by consulting the troubleshooting list

that follows. If you need service, please contact your service provider.

Unit won’t turn on

•

Make sure the unit is plugged in.

•

Check the wall receptacle (or extension cord) to make sure it is “live” by plugging in

something else.

Gateway appears to be locked up

•

First, try a power cycle, as this action preserves settings you have made in the gateway

configuration:

remove power to the gateway by disconnecting the power cord for 30

seconds, then reconnect it. Wait for the gateway startup steps to complete, then retry

operation.

•

As a last resort, press and hold the RESET button on the back of the unit for 15 seconds, then

release. Wait for the gateway startup steps to complete and retry operation. Remember, the

Reset process returns all configuration settings to the factory defaults.

No connection after more than 5 minutes

•

Make sure all connections are secure and try connecting to your service provider again. Verify

the Internet On/Off button is set to ON (the Online LED will be lit solid). If you still have

problems connecting to the network, contact your service provider.

Flashes during a stage of DOCSIS startup when upstream connectivity is

being established, e.g. while the gateway is first transmitting to the cable

operator to join the network.

getting an IP address, downloading configuration info, and completing

online registration. After completion of startup, indicates the state of the

Internet On/Off button.

Detailed Explanation of Jacks

The Wireless Cable Gateway provides the following data connections:

WAN Side:

Cable TV connection- connects to your cable service

LAN Side:

Ethernet RJ-45 jacks — connect up to four 10 or 100 Mbps Ethernet cables to PCs or to Ethernet

switches to connect more PCs. Each PC must be equipped with an Ethernet network interface, and

must have the TCP/IP protocol configured to operate over that interface.

USB- connects one USB cable to your PC. The PC must be equipped with a USB network interface.

In addition, the USB driver on the DCW725 CD-ROM must be installed on the connected PC, and

the PC must have the TCP/IP protocol configured to operate over that USB interface.

Wireless Card- utilizes the 2.4 GHz wireless 2-way technology built into the DCW725 to reach up

to 254 PCs in your home. Each PC must be equipped with an 802.11b/g Wireless Interface, and

must have the TCP/IP protocol configured to operate over that interface.
