Music server install: internet over electric lines

What makes running the coax line for your cable modem not possible in that room? Cable company's have rules their employees have to follow. When I was installing cable we where not allowed to wall fish cable at all. We could only run it from outside and then drill straight in or in some cases we could run it though a crawl space and angle drill from above. This is for single family homes only. For apartments of more than 4 units we could not run any outlets at all.

If you are in a house and the cable company can not run the outlet for you then you could still have it done by a custom wiring contractor that has less restrictions on what they can do. It will cost allot more though. If you go this route I would have them just run an ethernet cable from the room you have the modem in to the room you need the connection in. Reason being a custom contractor will not know if the signal is strong enough on the coax for the modem when they are finished because they lack a signal meter. Ethernet will work for as long a run as you will likely need unless you live in a stadium.

I've never tried it for audio but I use internet over AC for my son's XBOX....it's definitely fast enough for that and there's never been any hiccups

I also use one so my daughter can use Boxee in her room

I'm lucky, my modem/router is in the same built in as my gear. It was worth pulling RG6 up there for internet and cable, the BluRay player and cable box are each about a foot away

Sarcher30: Yes, you are correct that I could run an Ethernet cable from my home office router to my living room tuner but I prefer not to. The Ethernet cable would have to be installed on an outside wall and I prefer not to do this. The use of Ethernet over power using the ASUS PL-X32m provides the Internet connectivity I need and works great.

Everyone....thanks for your input; my solution will be to use the NA7004 with my second system, which is my HT set-up with the Marantz SR7005.
I can get internet to that location.
Thanks,
Jeff

No one product will suit all needs.. when I got my DLink package, it came with a little CD + App to run to test my connection from a laptop. Always do a "site survey" first to see if it works for you. What works for one place won't work for another, whether it be WiFi, MoCA, PowerLine Ethernet, etc...
