8.1 FAQ
Q. I have NAT enabled. My equipment is not connecting to the network
• The device's gateway has to be configured as the router.
Q. The router resets itself and the Ethernet connection fails.
•
The router will not function without an antenna. Keep the antenna as far as possible from
the power supply .
Q. I can’t access the Web server over NAT.
• The remote http access of the router has to be disabled, the default server address has to be
your web server and the gateway of the web server has to be the IP of the router.
Q. PPP connection fails. (DAT LED off)
• Check signal power. If signal power is weak you will need a better antenna. If the neighboring
cells have a similar signal strength, you will need to use a directional antenna. For proper
operation, the signal levels have to be in the range from -50dBm to -90dBm. It is necessary to
set ping, which will check the connection and, in the case of failed ping, restart the
connection.
Q. PPP connection cannot be established. (DAT LED off)

Q. L2TP or IPSec isn’t establishing.

router is restarted.
