So, I have my main incoming router (192.168.1.x) which had my ShineLanBox connected to it. I’ve then got a series of Eero mesh routers connected to that (192.168.4.x).
I’ve just swapped my ShineLanBox over to a port on an Eero router, so it now has an IP of 192.168.4.240
Hopefully now they’re on the same segment, things might improve. I’ll get back to you…
