Does anyone know what a Red LED on the AV500 extender means? I just installed the kit, the adapter is in my home, and the extender is in my work shop about 100 ft way. When I finalized installation I had a steady green powerline LED. After about 15 minutes or so, it turned red. I have a strong internet signal, speed it a little slower than I expected, but all in all, it appears to be working well. I would just like to know what the Red Powerline LED means.
