• 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.

Make sure you have entered the user name and password correctly. The default
user name is user, and the default password is 1234. These fields are case-
sensitive, so make sure [Caps Lock] is not on.

the WiMAX Modem. Log out of the WiMAX Modem in the other session, or ask the
person who is logged in to log out.

Disconnect and re-connect the power adapter or cord to the WiMAX Modem.

If this does not work, you have to reset the WiMAX Modem to its factory defaults.
