I'm wanting to connect my Blue Curve Gateway (on my main floor) to a PC in my basement via hardline. 

I don't have ethernet run in my home and so I'm wanting to connect these two points via a Moca connection as I have a coaxial outlet near the PC.

I noticed the Moca setting in the Blue Curve Gateway admin panel. Would turning this on force the router to output traffic back into the coaxial line? I'm wondering if I can get away with purchasing only 1 (expensive) moca adapter.

Also: does anyone know what version of the Moca protocol these gateways run? I'm hoping to make use of my internet 600 connection and if it's not running Moca 2.0 I'll likely have to buy 2 adapters regardless.

Thanks for the help!
