Troubleshooting

N300 Wireless Dual Band ADSL2+ Modem Router DGND3300v2 User Manual

Cannot Access the N300 Wireless Modem Router Menu

If you are unable to access the router’s menu from a computer on your local network, check

the following:

•

If you are using an Ethernet-connected computer, check the Ethernet connection

between the computer and the N300 wireless modem router.

•

Make sure your computer’s IP address is on the same subnet as the router. If you are

using the recommended addressing scheme, your computer’s address should be in the

range of 192.168.0.2 to 192.168.0.254. Click the link to

Preparing Your Network

Appendix

E to find your computer’s IP address.

•

If your computer’s IP address is shown as 169.254.x.x:, it might because recent versions

of Windows and MacOS generate and assign an IP address if the computer cannot reach

a DHCP server. These auto generated addresses are in the range of 169.254.x.x. If your

IP address is in this range, check the connection from the computer to the router and

reboot your computer.

•

If your router’s IP address was changed and you do not know the current IP address,

clear the router’s configuration to factory defaults. This sets the router’s IP address to

192.168.0.1 or http://www.routerlogin.net. This procedure is explained in

Restoring the

Factory Configuration Settings

on page

147.

•

Make sure your browser has Java, JavaScript, or ActiveX enabled. If you are using

Internet Explorer, click

Refresh

another screen, or your changes are lost.

•

Click the

Refresh

Reload

button in the Web browser. The changes might have

occurred, but the Web browser might be caching the old configuration.

The Ethernet port LEDs are off.

If the Ethernet port LEDs do not light when the Ethernet connection is

made, check the following:

• Make sure that the Ethernet cable connections are secure at the N300

wireless modem router and computer.

• Make sure that power is turned on to the connected modem or

computer.
