Ethernet to coax adapter

[haven888]

I am looking for a device to adapt ethernet cable to coax so the ethernet signal could travel bidirectionally without any degradation:


ROUTER
LAN port < === ethernet cable === (adapter) %===coax cable ===% (adapter) ==== ethernet cable=== PC


Goal is to re-use existing coax that runs from basement up to attic so I don't have to pull ethernet cable.

The only thing the adapter needs to do is bring ethernet -- no TV signal -- transparently in both directions between the ROUTER and the PC, without affecting the line quality/speed.

I would like to compare several devices against each other (price, size, AC versus battery, reliability).

Grateful for recommendations/caveats. Thanks

it is called MoCA

Thanks for the link.

Are there simpler adapters with a single ethernet port and a single coax port? I'll need two of these devices, one downstairs to convert the ethernet coming out of the router's LAN port to coax and another one upstairs to convert coax to ethernet so it can be connected to the NIC in the PC.

actually the MoCA devices are hard to find how about Powerline adapters?

I appreciate the suggestion. Unfortunately, it's an old house and the electric is its least-modern feature.

I expected there to be a wide choice of coax-to-ethernet adapters since both have been around for a long time. I don't need to carry the multimedia signal, just the ethernet.

I say running an ethernet line is cheaper and less complex though.
