Hello I am using a Teltonika RUT240 with chaos calmer installed.
I am using the LTE connection as a backup to my ethernet connection. Sometimes it does not switch back from using the LTE connection to WAN.
When I do "ping -I eth1 8.8.8.8" on the console nothing comes through. When I disconnect the ethernet cable and reconnect it the interface works, and the router switches back from LTE to WAN.
How can I further debug this?
kind regards,
Achim
I don't see this particular model supported. https://openwrt.org/toh/start?dataflt[Brand*~]=telt
Are you using the official firmware or some community made?
Regardless the Chaos Calmer is very old, insecure, and unsupported. You'd better upgrade to a newer version and then see if the problem persists.
I am using the stock Teltonika firmware.
I actually bought this model because of the integrated LTE and dual WAN capabilities.
Should I rather write to Teltonika support?
Yes, that would be the best.
Many OEMs use parts of OpenWrt in building their firmware, then remove large chunks of it, and replace other large pieces.
