Distance from exchange


[link to this post]
 
My nephew is experiencing extremely slow speeds on a bt product only receiving a connection of

6. Data rate: 256/160
7. Maximum data rate: 368/200
8. Noise margin: 7.0/6.3
9. Line attenuation: 31.5/63.5
10. Signal attenuation: 0.0/63.5

I see his downstream attenuation is 63.5 but according to samknows he is only 485m as the crow flies from the exchange, i realise that the line length will be longer but surely not so much so to give him such a bad connection?

Is the right-hand figure the downstream on every line? There are some routers where the report switches over in places. Whether or not, those are dreadful, but it would be nice to confirm.

Has it always been like this, or has it deteriorated?

Does his telephone work?

Haha it's starting to unfold now lol

He's just sent me pictures of the various different phone sockets scattered around his house!!
He's now connecting up hopefully to the master socket (the one with the openreach faceplate) and going to get back to me.

LOL
But if it's due to the wiring then even the master socket is likely to be poor. He needs to try in the test socket, if the master has one. I assume you know what/where that is, behind the faceplate?

What a difference being in the correct socket makes, I wish I this close before fibre!!!

6. Data rate: 448/8128
7. Maximum data rate: 1120/10300
8. Noise margin: 25.0/13.4
9. Line attenuation: 6.0/3.0

It seems a little alteration to the wiring might be a good idea tongue.

Is that in the test socket, or the normal external one of the master?

Normal one of the master and the same stats using the test socket, all he needs to do now is attempt to get bt to raise his profile!!

On possibility is that only one wire of the pair on the extension is actually connected. ADSL can work with ground return, but very, very poorly (I did an experiment once).

In any event, the household extension wiring needs to be revamped. It's clearly pretty awful given how close it is to the exchange.

Just as well the ISP didn't send an OR engineer. It would have proved an expensive fix.

That's and ADSL connection, not ADSL2+ so it's not going to run faster than 8mbps. I assume that exchange hasn't got 21CN & ADSL2+ available.
