10 FAQ

I can’t access the equipment, which is connected to the router, via internet and I have NAT ena-
bled.
• The device’s gateway has to be configured just as the router.

Router resets itself, connection on Ethernet fails.
• It is necessary to use an antenna, which will be situated far from the power supply.

PPP connection fails.
• Check signal power. If signal power is weak, you will have to use a better antenna. If the envi-
ronmental cells have a similar signal it will be necessary to use a directive antenna. Signal lev-
els have to be in the range -50 dBm and -90 dBm.
• It is necessary to set a ping, which will check the connection and, in the case of a fail ping,
restart connection.

PPP connection won’t be established.
• Recheck GPRS settings - APN, name, password and IP address.
• Try to enter PIN – verification if the SIM card hasn’t set PIN code.
• In a private APN it is appropriate to switch the DNS server send off.
• Switch log system on and observe where the error turns up.

Connection fails on Ethernet or connection isn’t establishing.
• On ethernet interface of the router it is possible to switch auto negotiation off and set a rate
and duplex by hand.

DynDNS not functional.
• In a private APN not functional.
• If the same IP address is recorded in your canonic name as dynamically assign address, it
means that the operator is using NAT or firewall.
• NAT is possible to verify by the help of the ping on address of your server with static IP ad-
dress and by the help of the router address verify and address in ping.
• Firewall is possible to verify, for example by remote access on the web interface.
•
The operator doesn’t give out the DNS servers address and without DNS server’s it is impos-
sible to connect to server dyndns.org. In log system will be this message:
– DynDNS daemon started
– Error resolving hostname: no such file or directory
– Connect to DynDNS server failed

IPSec tunnel is establishing but communication fails.
• Probably route conditionals of connected equipment are badly set up or the GW is set up
badly.

L2TP or IPSec isn’t establishing.
• Verify the reason in the log system.

I switched the router to offline mode by SMS message, but the router is in online mode after
restart.
• Control SMS messages don’t change the router configuration. For example, if the router is
switched to offline mode by SMS message the router will be in this mode up to the next re-
start. This behaviour is the same for next all control SMS messages.
