The Ethernet LED doesnt light up on my HomePlug Ethernet router?
A. Most likely, if the Ethernet LED doesnt light on your Broadband Powerline router is because the Ethernet port on it doesnt detect a LAN connection. Check your Ethernet adapter on your computer; make sure its enable and working properly. Also, check your Ethernet cable, make sure you use the right type, its plugged in correctly, and its working properly.
