Appendix A: Troubleshooting

If you cannot connect to the router from your PC, your network card may be configured
in such a way that it is not possible to connect to the router. Take one or more of the
following steps in order to solve the problem:
Make sure your PC's network card is configured to obtain the IP address form the
DHCP server (by default the DHCP server is running in the router).
Connect the router to the PC via Switch.
Connect the router to the PC, start the router first and then start the PC after the
router's initialization.
Ethernet connection fails or is not establishing.
It is possible to turn auto negotiation off and set a rate and duplex manually on the
Ethernet interface of the router. Available on "LAN Configuration" page in the router.
Mobile WAN connection fails.
Check the signal power ("Mobile WAN status" page). If the signal power is weak,
you will have to use a better antenna. If the neighbouring cells have a similar signal
strength, you will need to use a directional antenna. For proper operation, the signal
levels have to be good.
Try to enable automatic ping from the router, which will check the connection when
there are no data running and in the case of a failed ping, restart the connection.
This can be done on the "Mobile WAN Configuration" page in the router in the
"Check connection" section. "Enable + bind" option is to ensure the ping goes
always through Mobile WAN network interface.
Mobile WAN connection cannot be established.
Check the "Mobile WAN Configuration" – APN, name, password and IP address (all
can be blank).
Try to enter the SIM card PIN – verify that the SIM card has the PIN code entered.
Available on "Unlock SIM Card" page in the "Administration" section.
In a private APN it is not recommended to get the DNS settings from operator (on
"Mobile WAN" page)
Go to "System Log" page in "Status" section and observe where the error occurs.
I cannot connect from the Internet to the device behind the router. I have NAT
enabled.
The device's gateway has to be configured so it points to the router.
