How about this.

When I say splitter I am referring to the Lindy UTP Port Doubler.

Lounge End

• Connect a CAT5 cable from your modem to splitter behind AV Gear and plug it into the socket marked red.
• Connect a CAT5 cable from your splitter behind AV Gear and plug it into the socket marked blue and connect that to your x port switch.
• Connect the plug from splitter behind AV Gear to the Ethernet socket on your wall also behind the AV Gear.

Study End

• Connect a CAT5 cable from the splitter in the socket marked red to your wireless router (not the routers lan ports)
• Connect a CAT5 cable from your splitter socket marked blue to one of your routers lan ports.
• Connect the plug from the splitter into the Ethernet socket.

Hopefully both of the Ethernet sockets linking the two rooms have all 8 wires connected correctly.

I chose the socket marked red on the splitters for the link between the modem and router, and red meaning do not plug Ethernet devices here.

Hopefully I have explained that clear enough (well I hope I did), basically this should link up your router to your modem (red socket) as well as your Ethernet X port switch to your router (blue socket) and only use a single CAT5 cable between rooms and also keeping the modem to router link separate from the Ethernet lan, I am assuming that's what you wanted.

Also you may have to read the wiring information of the splitters to make sure your Ethernet sockets are wired up correctly to work with those.

To be honest I would of gone the 2 CAT5 Cable route, but the above route should work.

Hope that helps.

Yes, that's right. The splitters are colour-coded to identify which socket of one splitter connects to which socket of the other splitter. Eg if we connect the modem to the red socket in the lounge, then we know to connect the router EWAN port to the red socket in the study. And if we connect the switch to the blue socket in the lounge, we know to connect a router LAN port (1/2/3/4) to the blue socket in the study.

This achieves the ultimate aim of the router in the study. The modem can also easily be placed at the AV cabinet or the study with this approach (no rewiring or tools needed!), let me know if you want help achieving this.

Hi Paul,

Thank you thats just as I thought however would you please explain your comment for me?

I'm sorry but unless I'm totally misunderstanding things, I dont think its possible to move the modem to the AV unit unless BT move the master socket? Or is it that youre saying I connect an ethernet cable to the master socket which runs around the room to the AV unit and make the connections to the splitter there?

Ok just to add ....

What if at some stage I purchase a combined modem router, would that have to stay in the lounge or coukd it go to the study?

Finally any recommendation on which cable I should use?
Because the ethernet will be running inside a conduit along with some heavy duty speaker cable I thought FTP or STP would be best to eliminate possible interference?

Keep the modem, whether a separate or combined modem/router, as close as possible to the incoming line and master. It is noise on the DSL signal lines that you need to avoid. Ethernet is immune to most noise - of the domestic type and can easily run with speaker cables.

Standard Cat5e infrastructure cable (solid core) will be adequate. Terminate each end in a suitable patress box and RJ45, then use patch leads to connect from RJ45 socket to modem and to router.

Hi Paul,

Sure...
I always prefer to have cables separated that do different things.
So in your case I would have a separate cable going from the modem to router, but that's just me, I have drums of the cable here so I can go this route, but if I wanted to reduce the amount of cables being used I would probably of gone the splitter route.

Our house is all networked up using CAT5e or CAT6 (cannot remember, was a while back, most prob CAT5e) and all these cables are between all our internal walls, in our loft and under our floors and only leaving a few visible cables left to replace.

Don't get me wrong, I don't think there is anything wrong with using the other two pairs in the CAT5 cable for the link between the modem and router, hell I have seen the other two pairs in the CAT5 cable be used for the phone lines and PoE in my local college where I use to work many years ago.

But you may need to make sure that the two lots don't give you cross talk between each other, you should be fine.

I say just try the splitter route and if you are unlucky and have transfer/speed issues then just try a separate cable to see if that resolves the issue, but you should be fine.

If ethernet is immune to noise then surely running ethernet straight out of the master socket shouldn't be an issue should it?

Thank you for explaining Paul.
My study is already networked and I cant get a straight length of cable there without a load of disruption to the house. The only option is to use the existing network and the splitters.

You are not running Ethernet from the master socket - you are running DSL. They are totally different - different at all layers.
