Is there anyway to do this with the RUT-956?

Hello,

You’d be looking into using Failover in case you want to switch internet sources on failure, more information here: RUTX50 Failover - Teltonika Networks Wiki

*Note: I picked RUTX50 as a random device, but this will function with any of our routers that have multiple internet sources available (whether it’d be Wi-Fi, Mobile or Wired WAN).

Regards,
M.
