I'm wondering whether to send back the high speed dsl cable I've just bought from Tandy , connected it up instead of the cheap cable I'd been using it connected at the exact same rate but the through put speed was quarter of the cheap cable ?  so swapped them back and speed increased strange

[Geekofbroadband]

I was thinking the same thing. I had just the standard BT DSL cable then I tried the Cat6 DSL cables from eBay and then the Tandy Cable and the cheap BT DSL for some reason synced the highest. Does anyone think it would be because the actual twisted pairs inside the cable are longer even if the actual cable is the same length causing it to sync lower?

I just found it strange the same sync same ip profile but actual download speed about 25% of what it should have been

Speed test via a Ethernet wired connection?

Speed test via a Ethernet wired connection?

yes

one thing I was thinking about because the master socket is in an bad spot for dsl cables sticking out has any one taken the plug off a cable and hard wired it into ( A and B ) the socket ( would mean I could feed it out of the back less chance of it being knocked )

The SSFP has a pair of IDCs so marked, exactly for that purpose.

Remove the lower front face-plate and the two IDCs can be found at the top left corner. Please remember that solid cored wires, not stranded wires, are necessary when connecting to the IDCs.

I am using those A & B IDC sockets with 10 meters of Cat5e feeding up the wall and into roof space then down into another room and termiates at the data socket and then 1 meter of Cat6 DSL cable to modem.

I did some testing ages ago as was trying to get the
Vdsl signal back to my modem and router in another part of the house. Using a and b and linking that back I would lose anything between 8-10mb on the sync using cat 5e and tried some 6 but it was not much better. . In the end the solution was to run cat5e from the modem (in bridge mode) at the master socket back to router at the other end of the house. This leaves me with maxium sync at the original master socket and my router in the right place in the house for other devices and wifi coverage. Master socket was in the worst place possible. I was concerned getting OR to move it physically as it was a fair distance and the general feeling was it would decrease my sync rate further..
Best sync rate achieved with bog standard zyxel supplied dsl cable.
I have now wired the other rooms we needee doing as well now so its all on gigabit too.. lol my wife was not overally impressed with the various holes in the outer walls but its been worth it

Very weird.

I'm using the Tandy cables on my three modems, on an extremely long ADSL2 connection, and the cables perform fine.

Are you using ADSL or VDSL2 or what?

When doing this kind of testing, one has to be very careful not to upset the DLM Gods. But you had a speed _increase_ as well as a decrease, so any DLM-upset theory doesn't work. (See also :-

My cables are extremely short, 0.5 m and 1.0 m, so should really do nothing hopefully.

[Weaver]

One other thing, is there any mains cable near the DSL cables?

(O sages of kitz-land, would touching mains cable make a difference? )

[burakkucat]

Touching, as in running side-by-side, yes there would be inductive coupling between the two cables.

If a data cable has to cross a mains cable, they should be arranged such that they cross each other at an angle of ninety degrees. At that angle, no coupling will occur.

[Weaver]

@Burakkucat - Agreed. Exactly what my assumptions were.

[noddy]

my next question is does it matter which way round you link the A & B terminals ? to the extension socket 

[burakkucat]

No, the polarity is not relevant.
