can access the WiMAX Device, check the remote management settings and
firewall rules to find out why the WiMAX Device does not respond to HTTP.
• If your computer is connected wirelessly, use a computer that is connected to a
LAN/ETHERNET port.

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