User’s Guide 231
If you changed the IP address (Section 5.2 on page 58), 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.
2Check the hardware connections, and make sure the LEDs are behaving as
expected. See the Quick Start Guide and Section 1.2.1 on page 34.
3Make sure your Internet browser does not block pop-up windows and has
JavaScript and Java enabled. See Appendix C on page 289.
4If 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
299.
5Reset the WiMAX Modem to its factory defaults, and try to access the WiMAX
Modem with the default IP address. See Section 9.6 on page 107.
6If the problem continues, contact the network administrator or vendor, or try one
of the advanced suggestions.
Advanced Suggestions
Try to access the WiMAX Modem using another service, such as Telnet. If you
can access the WiMAX Modem, check the remote management settings and
firewall rules to find out why the WiMAX Modem does not respond to HTTP.
If your computer is connected wirelessly, use a computer that is connected to a
LAN/ETHERNET port.
I can see the Login screen, but I cannot log in to the WiMAX Modem.
1Make sure you have entered the user name and password correctly. The default
user name is admin, and the default password is 1234. These fields are case-
sensitive, so make sure [Caps Lock] is not on.
2You cannot log in to the web configurator while someone is using Telnet to access
the WiMAX Modem. Log out of the WiMAX Modem in the other session, or ask the
person who is logged in to log out.
3Disconnect and re-connect the power adapter or cord to the WiMAX Modem.
4If this does not work, you have to reset the WiMAX Modem to its factory defaults.
See Section 9.5 on page 106.
