Anyone have experience of this?  I could use some advice on it.

In our next house there is no data cabling installed.  One bedroom is used a lot for online gaming, and is located on a different level and at the opposite end of the house from where the router and wifi will be.  I think this room ideally needs a wired connection to the router.  Wireless is an option but the signal will only ever be average.

I'm going to see if someone can run a line, but in the absence of such a miracle my back up plan is EoC.

There is a coax cable carrying satellite signal to that room the house was built 4 years ago and the coax was professionally installed by a Freeview installer.  It's specified as quad shielded RG6.  I can get a Cat6 cable run to the satellite splitter quite easily. 

On that basis I think I could disconnect the correct coax cable from the splitter and use it for ethernet with pair of these adapters: -

But I've struggled to find info availability of this gear in NZ.  So I have bunch of questions: -

- Is it legal (seems to require no power source not even PoE)?
- Will it work on RG6 cable?
- Is 100Mbps fast enough for online gaming e.g. league of legends, minecraft?
- What am I missing, this seems to easy and simple - where is the rigmarole hiding?
