Art, you were right about the LED bulb! I forgot that I replaced my
closet bulb recently with a GE LED bulb that was subsidized by my power
company. So after reading your post I removed that LED light and my
powerline ethernet connection works again! I think I also bought it at
Lowe's, but I am not 100% sure of it.
Thanks for the excellent tip, Art!
