ER605 WAN/LAN1 online detection not working
I am trying to use the ER605 solely as a failover so that when my Comcast cable goes down, my Starlink ISP will kick in for as long as needed.
I have both the comcast and Starlink set in bridge mode, and have them plugged into WAN and WAN/LAN1 (both of which are configured as WAN). I have one of the LAN ports connected to my wireless mesh router.
No matter how I plug them in, the ISP on WAN will show as online under the online detection tab, and the ISP plugged into the WAN/LAN1 port will show as offline. Whichever ISP is plugged into the WAN port, that one shows as online and the other shows as offline. For what it's worth, the ISP on the WAN port is being delivered to my wireless router and my WIFI works on that ISP, but since the WAN/LAN1 shows as offline, I'm not getting any fail-over protection.
I've tried changing the WAN/LAN1 to manual detection with 8.8.8.8 and 8.8.4.4, and have tried changing the IP address of the ER605 to 192.168.2.1 -- as has been recommended here -- but neither helped.
Under the status tab, both ISP's show as 'link up" with their own dynamic IP addresses.
Can anyone see what I'm missing? Thanks.
