I had run a flat Cat 5e cable from the SageTV box and the router. Over the years I used that same cable for the MediaMVP and then the Tivo Premier.
When we recently redid the floors in our house I had the installer run that same flat cable under the hardwood. His work was incredible. But ...
The operation was a success but the patient died. The cable didn't work. I ran my Ethernet tester on it and it was bad. I guess it couldn't take the glue and hammering of the floor.
So I was in a mess. The Tivo simply won't work without Internet connectivity. There's no reasonable way to fish an Ethernet cable between the TV and the router. So it was off to BestBuy.
The salesperson there was pretty good on the problem. She offered the NETGEAR - Powerline Ethernet Adapter Kit and the TiVo - Wireless-N Network Adapter.
My early thinking was to go with the Tivo brand wireless adapter so I'd only have "one throat to choke." Further thinking took me back to the NETGEAR Powerline kit as I could drop a switch in the entertainment center and support multiple devices.
Turned out the NETGEAR Powerline kit was on sale for $79.99 and I came home with it.
It couldn't have been easier to install. The instructions didn't even have any words. Just pictures.
It worked immediately and has continued to since installation. I haven't tested the speed because I really don't care so long as it's faster than my DSL. I'm not moving any local data across it.
If you go read the reviews at the BestBuy site you'll see that everybody raves about the installation. A few mention the speed (rated at 85 Mbps) and every now and then somebody will say that theirs died. I've only had mine a couple of days so I can't speak to their longevity.
Pretty nice gadget.
