Is ethernet over coax dead for retail?

post #1 of 7
Thread Starter 
Note - I posted this question in the networking forum, where I think it belongs. This thread can be deleted.

We're moving in to a new house at the end of the month and it is not prewired with Cat5e/6 - it might have Cat5 behind the phone outlets. I need to connect the office, which will have the cable modem, wireless router, NAS and office computer (plus laptop) with the basement which will have the Wii and Media Center PC and with the living room, which will have the Xbox 360, acting as a Media Center extender.

I originally thought about powerline adapters, but the basement is on a separate sub-panel and I don't think I would get great performance there. Someone recommended MoCA bridges, which I think will work well - there is no shortage of coax connections in the house.

The only problem is I can't find any retail store (local or online) that has them in stock. I'm looking for either the Actiontec, Netgear or D-link products. All 3 show out of stock at newegg, amazon, Walmart, Best-Buy, etc... all I see are off-sites I've never heard of. Am I missing something? Are all the main producers giving up on these in the retail market. If so, that's a shame, these seem to be exactly what I need. Are there other brands or retailers I should consider?

The coax already in the house is probably RG6 or RG59 for CATV. These are both 75ohm cables and will not work for Ethernet which used 50ohm cable. Yes a cable modem uses 75ohm cable but that's not Ethernet at that point.

Furthermore coaxial Ethernet (also called Thinnet) is obsolete. It was also limited to 10mbs which is too slow for modern applications.

Your choices are mainly wireless or CAT5E runs.

BTW, there is no cheating with the 75ohm cable. Many have tried and it simply won't work at all for Thinnet based Ethernet.

Coax has more than ten times the bandwidth of Cat5e, and there are plenty of medium to translate ethernet over it. Try looking into Wi3 WiPnet, allows Media Over CoAx (MOCA) and allows the cable and/or modem signal to pass as well. Dont forget the WiPlock filter so your neighbor can't bring home a WiPnet and get onto your network.

He's talking about the modern, residential-focued solution called MoCA, not thinnet.

http://www.mocalliance.org/

MoCA isn't dead, systems like DirecTV's DVRs use it (although in a different frequency range for compatibility with their setup).

I assume it's gone from retail because of the ubiquity of both wireless networking in the homes and the easy availability of wireless adapters (or just plain built-in) for the common devices that need it (game consoles, BD players, etc.).

Not sure why it's so out of stock online... AFAIK the setup works, so I don't think that was the issue.

I would look at either the simple dedicated wireless adapters for the game consoles (if you only have one component in the area that needs connectivity), and a wireless bridge to create islands in the room where you have multiple devices.

Yep, wireless devices for these purposes are ubiquitous these days.

You can use DirecTV's Broadband adapters for ethernet over coax as mentioned here > http://www.solidsignal.com/pview.asp...ply-(DECABB1R0)

They can be had for as little as $20 each on ebay > http://www.ebay.com/itm/DECA-BROADBA...item519d4a6001

amazon has plenty of moca adapters including the actiontech
