Greetings all. I have the RUT240 unit, which I purchased to provide an LTE failover connection should my primary wired internet connection go out. I have Spectrum as my primary cable internet provider and I use a T-Mobile data only plan for my failover service. The RUT240 is connected between my cable modem via WAN and my Linksys router via LAN. Normally, when my primary cable internet is up and running, the RUT is able to seamlessly pass that data connection through to my router without issue. Recently, I had a cable internet outage, however the RUT240 did not automatically fail over to mobile data despite being programmed this way. I had to physically unplug the ethernet cable between the WAN port and the cable modem in order for the RUT240 to take over and provide wireless internet. It seems like as long as the cable modem and RUT240 are connected, the RUT always tries to use the primary wired connection, even when the wired connection goes down. Are there any settings I need to adjust so that when the primary cable connection goes down, the RUT will switch to mobile data without me having to unplug the WAN cable every time?
My Spectrum modem is a Motorola E31U2V1 if it matters. It is a modem only, without a router/switch/wireless built in.
