Re: What fibre speed should I be getting, based on these figures?

you may be better looking at your local paper for a telecom engineer and see if they can do what you want - probably ex openreach anyway

Re: What fibre speed should I be getting, based on these figures?

if you have extension wiring connected to bottom master faceplate have you tried removing the bellwire from terminal 3 in master and extensions  you only connections on termianls 2&5    

bellwire removal

Re: What fibre speed should I be getting, based on these figures?

The master socket had an I-Plate retrofitted. Bizaarly, removing it has increased the speed at the entension (original post).

 

6. Data rate:9995 / 39993
7. Maximum data rate:18638 / 42757
8. Noise margin:12.1 / 8.0
9. Line attenuation:28.0 / 21.0
10. Signal attenuation:27.9 / 18.7

 

But not to the speed of the test socket. The extension is flat cable, so I suspect that may be a problem.

 

Would I be better wiring the extension in in Cat5 cable?

Re: What fibre speed should I be getting, based on these figures?

You could or you get a longer rj11 shielded modem cable which should be ok. So leave router at test/master and then run rj11 to hub

Re: What fibre speed should I be getting, based on these figures?

With the modem/router plugged directly into the NTE5 master socket the speed is slower than plugged into the test socket, so I think the extension wiring must be adding noise.

 

This is the test socket speed:

 

6. Data rate:	        9995 / 39993
7. Maximum data rate:	19506 / 57298
8. Noise margin:	12.7 / 11.7
9. Line attenuation:	25.5 / 20.5
10. Signal attenuation:	25.4 / 20.0

This is the master socket front plate speed (with extension wiring attached):

 

6. Data rate:	        9995 / 39993
7. Maximum data rate:	18638 / 42757
8. Noise margin:	12.1 / 8.0
9. Line attenuation:	28.0 / 21.0
10. Signal attenuation:	27.9 / 18.

Keeping the modem at the master socket isn't practical, as there is no nearby electrical supply, plus I have ethernet connections which are routed to near the extension socket. I therefore need to maximise the potential speed at the extension socket.

 

p.s. it is a HomeHub5, so doesn't have a seperate router and hub.

Re: What fibre speed should I be getting, based on these figures?

I can't see where I said you had a separate modem!

 

instead of using the 10m of extension cable to run from master to router you could use an rj11 modem cable (this is the cable which connects from filter to hub) which is shielded and gives better connection

Re: What fibre speed should I be getting, based on these figures?

I've replaced the flat extension cable with CAT5 2 pair CW1724. Replaced the extension socket for a double one with in-built ADSL filter and omitted the bell wire. Replaced the modem cable with a 1 metre long CAT5 cable. This is the result:

 

6. Data rate:	        9995 / 39993
7. Maximum data rate:	19083 / 53981
8. Noise margin:	12.3 / 10.7
9. Line attenuation:	25.7 / 20.8
10. Signal attenuation:	25.5 / 20.0

Re: What fibre speed should I be getting, based on these figures?

Looking good and when you get the infinity 1 upgrade it will be even better

 

well worth the effort

Re: What fibre speed should I be getting, based on these figures?

I've only been contracted to Infinity 1 for ~2 months, just before the speed increase to 52mb, so I have another ~10 months to wait to contract renewal to get the upgraded speed.

Re: What fibre speed should I be getting, based on these figures?

No, I think they are rolling it out to everyone now. Even if they weren't you could have re-contracted.
