I have a Multitech Conduit working as a packet forwarder, connected via ethernet cable to a router with a 3G connection to the internet.
The application seems to work fine for a while, but after a few days can’t see the packets sent by my mDots in the TTN console anymore. The gateway seems to be properly connected to TTN, as its “Last seen” field is updated every 30 seconds and using tcpdump I can see the status packets and the mDot packets being forwarded to TTN. But the packets are lost “somewhere”.
If I reboot the Conduit the packets start arriving TTN again and will work for a few days until the issue starts again.
I think this started when we changed the internet connection of the router from ADSL to 3G, but I’m very not sure. Can this change be related somehow with the trouble I’m having? Any other suggestion?
