I have a RUTX12 router with external WAN internet and both SIM's data plans setup so in total 3 WAN connections.
I am running the latest firm RUTX_R_00.07.02.2 and 24 hours ago performed a factory reset and started from scratch, the problem was present before and after the factory reset.
External WAN is setup as primary connection with SIM 2 to follow then finally SIM 1.
When I unplug the WAN connection, failover does not detect a drop in connection and remains as the external WAN as my connection meaning my internet drops out and nothing loads.
I have also tried applying individual failover plans per device and these do not apply. I have however noticed they do work once the router has been restarted. The same happens when changing interface priority, even though apply is being clicked, nothing seems to happen until reboot.
My main reason for using this router is for the dual SIM failover so this is a major problem for me.
