From the time I purchased the Chateau LTE12, I have not been able to use it as a router. Every time the LTE connection goes down for a split second (which can happen several times an hour), it breaks all active TCP connections, i.e. downloads, video calls, etc all freeze or drop out.
Up until now, the only workaround I found is to pass-through the LTE connection to an Ethernet port and use another router to do the routing. The second router never sees the split second LTE interruptions and thus never breaks active TCP connections. There is just a slight pause in voice/video calls.
I recently bought the Chateau 5G in a hope that the split second LTE interruptions was a modem issue with the LTE12 model. However, they still occur:
So as a feature request, I would like a setting to give a grace period before marking an LTE connection as down. I.e. it would be better to drop packets during the split-second interruption than close the route, breaking active TCP connections.
