In reply to a post by MrSaffron:

The BT installed cat5 cable is NOT wired for carrying ethernet data, it is only meant to carry VDSL data from telephone line to openreach modem.

Having seen this I opened the socket in the back room and whilst all the wires are there they are not all connected, it has an rj45 plug on the other end, do you know if this is similarly not connected. If it is not connected I assume that all I need to do is to get another socket cut the plug off and connect the cables in the right places, and connect all the cables at other end. As an aside whilst it may be a BT supplied extension they did not fit it, a kindly BT open reach engineer supplied it and I fitted it.
Can I thank you so much for the help you have given me so far it has been most helpful.

Hi Bill, this might help you sort the Cat 5e cable problem with a very good video.

So looking at that could I use a spare modem router to do the same job, I have a netgear dgn1000 router in my drawer, would this do the job? Is there anything I would have to do to make it work or could I just plug my primary router to the Bt socket, the cat5 cable to the primary router, the netgear dg1000 to the socket and then the netgear to my desktop and wireless for everything else in the back room?

Hi Bill, to find some devices on the network, you need to setup a static IP address for these device and not within your router DHCP server range.

My router DHCP server range settings.

DHCP Start: 192.168.1.21
DHCP End: 192.168.1.250

I have my router static IP address 192.168.1.251
2Wire router/wireless access point, static IP address 192.168.1.253 the DHCP server disabled.
Computer static IP address 192.168.1.3
Samsung TV static IP address 192.168.1.6

Also if you redo that extension so it handles ethernet, best to label it as such, in case someone gets confused at a later date

Though suspect it should be fine for VDSL2 even with ethernet style wiring

Thankyou to everyone for all your help, amongst other things you have saved me at least £50 on the cost of home plugs and possibly more. All I have to do now is to decide whether to buy a RJ45 socket plate and case and then cut the plug off the cable at the master socket end, I am reluctant to do t s once I do it the result is permanent with no going back to a system that does work after a fashion. I think I will probably buy a couple of home plugs http://www.broadbandbuyer.co.uk/Shop/ShopDetail.asp?... and see how we go from there, this is the option that saves me £50 as using these with the knowledge you have given me means that I do not have to buy a wireless home plug.
Thank you once again.

Just to back up Andrew's comment, I am assuming VDSL still uses a single twisted pair.

If you can punch-down (or recrimp but not so easy) for standard ethernet straight through wiring, that would not stop you using the wire for VDSL, ADSL or even phone extension in future. These would normally use just the centre pair 4+5 (conventionally the blue pair).

In fact you can even share that wire. Using just 1+2 and 3+6 will do 100M ethernet leaving the centre pair free.
Some ethernet cable "economiser" adapters used as a pair have a similar result by splitting the connectors into double sockets 1+2,3+6 and 4+5,7+8.

(edit) but if you punch-down the connections yourself at least you know what you are getting.

So making it an ethernet cable allows either use at the full 1G or still a mix of 100M plus "something else". Assuming it is 90m or less!

Correct VDSL still uses the centre pair of pins, proof is that things like old faceplates and microfilters still work.

That was what I thought but my supervisor at home would prefer it if I did not do anything that if I made a mess of it would prevent me from putting the system back as it is now (:- which is why I ordered a couple of home plugs this morning. But thankyou for suggesting it

I have two Netgear XE104's which are old but one advantage is they have four 10/100 Ethernet ports instead of just one, I have a router, xbox, ps3, computer and a Humax box plugged into one end and another computer at the other.

Are there any current Homeplugs that have four ports? Seems a waste of plugs to have to buy 4 if most of your net devices are in one area.

There are devolo units with three ethernet sockets
