Cannot Access the 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 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. Refer to
“Preparing Your Network” in Appendix C
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 will set the router’s IP address to 192.168.0.1.
This procedure is explained in
“Restoring the Factory Configuration Settings” in Appendix B
.
•
Make sure your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet
Explorer, click Refresh to be sure the Java applet is loaded.
•
Try quitting the browser and launching it again.
•
Make sure you are using the correct login information. The login name is
admin
and the
default password is
password
. Make sure that Caps Lock is off when entering this
information.
If the modem router does not save changes you have made in the modem router menu, check the
following:
•
When entering configuration settings, be sure to click the
Apply
button before moving to
another screen, or your changes are lost.
•
Click the Refresh or Reload button in the Web browser. The changes may have occurred, but
the Web browser may be caching the old configuration.
