I had the same problem trying to connect my non wi-fi LG blue ray player and my Pioneer VSX-60 AV receiver. For 7 days I've been trying to figure out why I wasn't able to get an I internet connection to either one. I happened to see the post by Comcast Andrew. Then it made sense why I couldn't update the firmware on my Pioneer receiver and my LG blue ray player.
So, I happened to find 2 Netgear 85 Mbs Powerline Network Adapter I had. I connected one of the 2 Adapters using an Ethernet CAT5 cable to my X1 router Ethernet connection and then I plugged that Adapter into my wall electrical outlet. Then I connected the other Adapter into the wall electrical outlet and using another CAT5 cable I connected it to my LG blue-ray player. I was able to get an I internet connection and I was able to update my LG.
You can of course purchase a Powerline Network Adapter locally or online.
