Hi there—I’ve had an eero 5 system running beautifully in my house for eighteen months or so. The last week, two of the devices—the two furthest from the router—started going red and losing connection. They’ve worked fine, nothing’s changed in the house etc, or their placement, but they suddenly won’t keep connected. I’ve tried soft resets, removing them from the system then adding them as new, the same thing happens. It’s driving me a bit nuts—they worked brilliantly and now they don’t! Any advice?
