I installed the Fios network extender and the wifi is working great. When I connect my Mac (both the Macbook Pro and the Mac Mini) to the ethernet jack on the back of the device, I get a "Self assigned IP address" error and the Mac won't connect to the internet via the hardwired connection.
I've rebooted all the devices and renewed the DCHP lease. I'm running macOS Big Sur (11.2.3)
