@Kevin_Z there is nothing at all coming out of them. Devices see no Ethernet signal of any sort from router. Have phones, TVs, Roku, Kodi boxes, none of them see anything. I've had different type...

@Kevin_Z have brand newC5400. Wifi works great not one Ethernet port works. Says I have no clients, and yet I have 8 devices connected directly to 5400.

@TeeJay Mine do not work at all. Have no idea why not.
