So I have a TrendNet TEW-824DRU running DD-WRT. I have up until now had home automation / security systems that had cellular failover that was integrated into the hub / security console. (ADT Smartthings). Since Samsung is killing the devices and their function off (yay cloud services!)

Anyway I have migrated to Hubitat. The compatible LTE modem they list does not support my cellular carrier. I am considering setting up DD-WRT for a failover dual WAN with an LTE / Ethernet modem. But my questions are...

#1. Does anyone have pointers to the latest documentation on configuring dual WAN failover configuration?
#2. Can anyone recommend a reasonably priced LTE / ethernet modem that is compatible with the AT&T network?

That wiki applies to Broadcom, pre-r46604 build. Someone needs to take on the task of writing instructions for swconfig.
