Troubleshooting

This Chapter provides solutions to problems that can occur during the installation and

operation of the DI-724U Wireless G QoS Router. We cover various aspects of the

network setup, including the network adapters. Please read the following if you are

having problems.

Note: It is recommended that you use an Ethernet connection to conﬁgure the

DI-724U Wireless G QoS Router.

1. The computer used to conﬁgure the DI-724U cannot access the Conﬁguration

menu.

 Check that the Ethernet LED on the DI-724U is ON. If the LED is not ON, check

that the cable for the Ethernet connection is securely inserted.

 Check that the Ethernet Adapter is working properly. Please see item 3 (Check

that the drivers for the network adapters are installed properly) in this

Troubleshooting section to check that the drivers are loaded properly.

 Check that the IP Address is in the same range and subnet as the DI-724U.

Please see Checking the IP Address in Windows XP in the Networking

Basics section of this manual.

Note: The IP Address of the DI-724U is 192.168.0.1. All the computers on the network

must have a unique IP Address in the same range, e.g., 192.168.0.x. Any computers

that have identical IP Addresses will not be visible on the network. They must all have

the same subnet mask, e.g., 255.255.255.0.

 Do a Ping test to make sure that the DI-724U is responding. Go to Start>Run>Type

Command>Type ping 192.168.0.1. A successful ping will show four replies.

Note: If you have changed the default IP Address, make sure to ping the correct IP

Address assigned to the DI-724U.
