7. Troubleshooting
7.1 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)
Recheck GPRS settings - APN, name, password and IP address.
Try to enter PIN – verify if the SIM card has the PIN code set.
In a private APN, switch the DNS server send off.
Switch the system log on and observe where the error occurs.
Q. FTP doesn’t function.
Router doesn’t support active FTP mode. It supports passive mode only.
Q. RS-232 doesn’t function.
Verify that the router supports RS-232 communications. Also verify the RS-232
communication settings. To do so, open the router’s configuration menu via the web
browser, select the appropriate expansion port and verify the settings in the
configuration menu.
Q. L2TP or IPSec isn’t establishing.
Check the system log for error messages.
