Right, long short im afraid. My friend lives in the sticks and gets crappy speed. To boost his speed I got him a DG834GT and thats working great, 2.5Mb instead of 1.5Mb.

He lives in a big house (4 floors, 6 Bed) and the Master Socket is located in the garage, under the first floor (so technically 5 floors if you count the garage)

To get the best sync speed, I placed the DG834GT in the garage in Modem Only Mode (running DGTeam FW) and ran an ethernet cable to the second floor where most of the devices WERE located and where I put a WRT54GL (with Tomato FW)

This works good, but his modem is getting damp down in the garage and is dropping sync a bit.

I have fitted an ADSL Nation Filtered Faceplate and have connected all of their existing telephone sockets to the back of the socket.


Anyway, they have recently moved their study into the 5th floor (converted loft) and the wireless is quite low signal. So what I want to do is move both the modem and router to the top floor.

Im not sure how I can still use the Filtered faceplate to achieve this, I basically want to run the filtered side of the faceplate up to the loft where the modem will be. I will be using Shielded Cat6 for this. I need to keep all the Phone sockets connected down into the garage, but run a line up for the ADSL. (Run will be about 40m)

Is this possible? Am I over complicating it? Do you understand what I just said?

Thanks
 
Not sure if you might be better using BT spec cable CW1308 (or similar number I forget) with the correct cable type, thickness and number of twists per metre to extend the unfiltered telephone signal. Cat6 would probably work fine but there's a reason why BT use one spec over another.

Terminate with the appropriate connectors and it'll be just like a really long modem lead.
 
I’m amazed the modem is managing to get damp. Most of them run hot enough to keep themselves dry unless there’s actually water running down the walls.

I'd agree that there'd be no benefit (but no harm) in using Cat6 for this, and certainly no benefit over using Cat5. The signal has made it down several kilometres of old BT copper, another 40 metres shouldn’t make much difference unless you use some really nasty untwisted cable.

I believe that screened cable can cause more problems than it solves unless you actually have somewhere to ground the shielding to.

In this situation my first step would be to temporarily unfilter the telephone extensions and see if you can get a decent sync from one of them. If they’ve been wired with the correct cable (and the ring wires are disconnected) then there’s no reason why they should perform any worse than your proposed 40m extension would.
 
The telephone extensions are using alarm cable because my friends dad build the house and had a roll of it left over after installing the alarm. So thats a definate no-go area.

I don't know how its getting damp either. I think it may be on some metal shelving?

I think im going to suggest mounting the modem to the wall in the garage then running one long cat5/6 cable up to the loft and put the router in there...

Don't know why I didn't think of that in the first place really.
 
Yep, alarm cable makes it a no go for adsl.

As there's already a cable from the garage to the second floor couldn’t you relocate the modem to there?

You could then extend the network upwards through the house using powerline adapters.

You could even get wireless working on them both and improve the coverage.
 
We recently did this at work. we plugged the phone cable in to the filter, and then put an rj45 on the other end, which then went into an adaptor with a female rj45 on the other side. We basically then plugged in the ethernet cable and ran it down the corridor to the room we moved to and patched it in.

*edit was half a sleep when writing this. The suggestion above sounds a lot better!

The cable going to the second floor is RJ45 Cat5e cable. It was used to link the modem in the garage to the router on the 2nd floor.

There are no problems getting cable round the house, my friends dad built it so knows the way if you know what I mean. There is 1 ethernet cable running from the 2nd floor to the top floor (wrong room though)

That length of Cat5e would work fine as an adsl extension cable. You'd just need to change the attached plugs (and probably only the one at the modem end).
