TTN gateway lost internet connection

Hello guys!
I have a TTN gateway connected by cable to a 3G router with a weak signal (with lot of surrounding noise). I don’t have any physical access to the gateway but someone to power / unpower it.
The gateway somehow looses the connection to the router. Before rebooting the gateway, the 2nd LED is blinking fast with the first one ON. This means that the internet connection failed. We suspect that this comes from the poor 3G signal strength.
After rebooting, all LEDs are ON and the data transfer too. Then, it stops after a few hours.
I don’t know the flashed firmware version. Is there a mean to get it remotely?

Do you know how to solve this connection problem?
