Which home plugs? They aren't all created equal

Something like one of these is a lot cheaper.

Homeplugs tend to be bulkier than straightforward 13A plugs so you need to be a bit careful which one you choose, but I picked up a couple in Tesco's and they work fine.

my DG934g is V4 so.........

General electrical advice is not to have one of those socket doublers with an extension lead plugged in (which is what you would need to do to achieve the same goal. Also, those doublers have in the past had a very bad reputation for catching fire - possibly might be better these days but I tend to steer clear of them.

Just to add to this, it's surge-protected extensions that really reduce the connection speed of Homeplugs. Plain extensions usually work, although again the speed is reduced somewhat. (the technology as a whole is variable, as it uses the same techniques as ADSL, ie, a broad range of frequencies are used as available)

As you have a set now, why not try just putting them into the existing wall sockets and see if you get a link?

If that works, it's not that hard to change a single socket for a double one properly, ie, chop out the backbox and fit a bigger one. DIY-able for a tenner, or a spark would take an hour to do it at most.

I take your point, but it's like all electrical apparatus- it's OK if used properly and checked regularly, and not if it isn't.

Same applies to extension leads.

Go on, live dangerously

So you are on a Market 1 exchange, NDWAD, that only has 20CN BTW based products available.

master socket in kitchen no idea about the other

So there is another telephone socket, an extension, in the house. There is a possibility that the extension could be used -- not an ideal solution, granted, but may be as a means to provide you with some form of BB connection. If you are up to it, an external photograph of both the NTE5A (master) & extension sockets, plus a clear photograph of the wiring within the extension & behind the EU removable lower front panel of the NTE5A would be helpful. Where in the house is that extension socket?

Not only do you have my attention (sorry, Wadhust, East Sussex, is too far away for me to visit) but also that of others with plenty of practical advice. (If you are really lucky, there may be someone reading this in South London, Kent, Surrey or one of the Sussex's who would be willing to pay you a weekend visit . . . )

Objections, objections! Not worth a try? The most you can do is un-brick it

sorry i worded that badly I have only one socket a master socket on top of a kitchen cabinet.

when i said not sure about the other I meant I didn't know the answer to your other question regarding the master socket.

did I put wadhurst??? sorry i live in Hawkhurst.

when i said not sure about the other I meant I didn't know the answer to your other question regarding the master socket.

Sorry, I misunderstood. Please look at the two pictures, here. On the left is shown an NTE5 with the EU (end-user) lower front panel removed, whereas the picture on the right is of an LJ2. They should allow you to identify the type of socket you have above the kitchen cabinet.

The ideal solution for you would be to have a "wire man" install an extension socket for the modem/router/WAP in the general area where you use the laptop (wirelessly) and to run an Ethernet cable from the router up to the tower computer, on the top floor of the house.

So you are just over the county boundary and in Kent. The Hawkhurst exchange, NDHAK, is very similar to that at Wadhurst -- another Market 1 exchange.
