I have my BT infinity installed in a room in my home.
As I am renovating and moving my computer to another room, I need to move my HH and Modem.

I have decided that I do not want to leave the modem where it is and run a cat 5. I want to move the entire lot.

BT charge a silly amount to do this so. What if I cut the cable before the socket, re run the cable to the new point and re join it in a junction at its new location.

Providing the join is secure (properly crimped/soldered/terminated) would there be any issues? The cable and junction will be hidden in a cable management box and won't be seen.
 
Moving a BT master socket yourself is a bad idea for several good reasons. The main one is that it belongs to BT and they'll be VERY unhappy if they ever find out. If you do move it pray that you never have a line fault at any time in the future as it could get expensive.

Why don't you just hard wire an extension from the master socket to where ever you want the modem and router to be? The wiring involved will be exactly the same as moving the socket, and there's nothing to go wrong.
 
hmmmmm if it costs £130 to call BT out to move it, and they don't keep a record of its current location, what have I got to lose by moving it myself? Worst case I call them out and they charge me £130. As I say, I am renovating and I want to move the lot. Im actually moving my office to another room.

Your BT line will be longer which might cause the sync to drop slightly.
 
Leave the master socket and modem alone. I believe with infinity the demarcation point is the modem itself.

Hide the modem and run a cable to a new router in the new office :)

I would go with this, this is probably the cheapest option. I have something similar, the modem is next to the master socket, hidden away by being mounted on a wall behind a small cupboard, and then a cat 5e cable running under the floor to the room where the router is.
 
As has been said, BT don't document the master socket location, and it's often contractors that come and do it for OpenReach. If you are competent, I'd say go for it.

I got the engineer to move mine when I had Infinity installed, but if he'd been reluctant, I'd have done it.
 
Can't see a problem moving it just take a few pic of the wiring config remember Broadband has to be the first line in the house and then the phone signal goes out their after. I would advice not to extend the VDSL side of the modem you really want that as short as possible. My modem was upstairs i moved it downstairs where the cable comes into the house and installed a new master socket then ran CAT6a to the router, i got 5000Kbps more on my Sync rate.
Now i think i'm going to Run CAT6a from the master socket for my A&B pair to the box that is inside the house that joins the outside cable and see what i get :D

If your extension wiring is done properly then the sync shouldn't be affected to any noticeable degree. Adding a few metres of good cable onto the end of several hundred metres of BT's nasty old copper can't do much harm. My own connection is extended from the master socket to my office using one pair of a Cat5e cable (voice lines using two other pairs) and the sync is unchanged.

You appear to have changed several variables at the same time, so there's no good way of knowing which one improved the sync. Using Cat6a in preference to Cat5e for the connection between the modem and the router won't have made any difference.

Replacing BT's side of the cabling could help if it's in a horrible state, but that isn't something we're supposed to mess with.

Seven variables? No. The modem was moved downstairs as thats where the master socket is now that got rid of 15/20 meters of cable on the VDSL side of the modem which gave 5000kbps that is significant the CAT6a was only a connection point as i didn't want the router downstairs and this way around would not encore any loss the only thing that's change is the length of the VDSL side.
BT don't install good cable, the cable isn't in a bad state, just means things like cross talk and RF is known about more and cables have been made to get this as low as possible i'm trying to get the things that i can change in my house done so my home isn't a limit point to. Just a shame i can't get BT to replace the cable to the cab lol. Current sync speed 49000/51000kbps fluctuating, not sure i'll get anything out of the short run, but the cable is cheap enough so its worth it and im a tinkera lol

VDSL is a much higher frequency spectrum than ADSL/ADSL2+. Basic rule is higher frequencies attenuate faster. So if you are at the right attenuation length (about 600-800m of BT D side cable) then adding even a meter can drop your sync rates.

@OP
Its really hard to give good advice on internal cabling without knowing all details but:
Openreach NTE must be first socket on line
Openreach SSFP (microfilter on nte) must be on the NTE
Openreach VDSL modem must be connected to this socket via rj11 lead
There will be black BT underground or overhead cable coming in somewhere, do not move the fixingings for overhead cable, you can run new cable from this point to your nte if you wish, crimps do fine on the A+B.
From UG/OH cable to NTE any joints must be properly sealed (aka closed, not "sealed" like you or I would think) and crimped with no star wiring.

If you stick to this then your all good

I didn't intend to, or actually, claim that extension wiring wouldn't make a difference, just that the difference shouldn't be that significant. A 5 Mbps gain wouldn't be explained by just removing extension wiring unless there was an pre-existing problem.

In this case the extension may have been longer that you'd usually expect. With 20 metres of extension cable I could easily reach most of the rooms in my neighbour's houses.

hmmmmm.
looks like I have 2 choices.
a) Leave the modem where it is and run a cat 5.
b) Take up the existing cable and re-route it.

Its not my skills I question, its Openreach's.
To get this thing working, I had one contractor, two useless BT Techies and a senior Engineer come down 4 times in 4 months.
What is the limit of the length a cat 5 run can be?
is 20 meters ok?
 
Thanks...
I had another idea. Im getting a new HH4 (TY BT for sending one out).
As its dual band, will I see a big drop in speeds if I connected wirelessly as opposed to a catV in to the gig port? (for downloading large files. Im assuming streaming should hold out. I get around 70mbps-75mbps download and latency of 19-22 on speedtest)
