21.2 WiMAX Modem Access and Login
u I forgot the IP address for the WiMAX Modem.
1 The default IP address is http://192.168.100.1.
2 If you changed the IP address and have forgotten it, you might get the IP address of the
WiMAX Modem by looking up the IP address of the default gateway for your computer.
To do this in most Windows computers, click Start > Run, enter cmd, and then enter
ipconfig. The IP address of the Default Gateway might be the IP address of the
WiMAX Modem (it depends on the network), so enter this IP address in your Internet
browser.
3 If this does not work, you have to reset the WiMAX Modem to its factory defaults. See
Section 21.1 on page 217.
u I forgot the password.
1 The default password is 1234.
2 If this does not work, you have to reset the WiMAX Modem to its factory defaults. See
Section 10.5 on page 106.

1 Make sure you are using the correct IP address.
• The default IP address is http://192.168.100.1.
• If you changed the IP address (Section 5.2 on page 54), use the new IP address.
• If you changed the IP address and have forgotten it, see the troubleshooting
suggestions for
I forgot the IP address for the WiMAX Modem.
2 Check the hardware connections, and make sure the LEDs are behaving as expected. See
the Quick Start Guide and
Section 1.2.1 on page 33.
3 Make sure your Internet browser does not block pop-up windows and has JavaScript and
Java enabled. See
Appendix C on page 259.
4 If there is a DHCP server on your network, make sure your computer is using a dynamic
IP address. Your WiMAX Modem is a DHCP server by default.
If there is no DHCP server on your network, make sure your computer’s IP address is in
the same subnet as the WiMAX Modem. See
Appendix D on page 267.
5 Reset the WiMAX Modem to its factory defaults, and try to access the WiMAX Modem
with the default IP address. See
Section 10.6 on page 108.
6 If the problem continues, contact the network administrator or vendor, or try one of the
advanced suggestions.
