Is this the best I can get on Fiber?


[link to this post]
 
Hello Experts.. smile

Just signed up fiber with TalkTalk couple of days ago, it was estimated that I would get about 32-35Mb download speed.

But I'm only getting about 23Mb/24Mb, can my line handle anything better from these stats?

Up
Connection status:
Showtime
Upstream line rate (kbit/s):
1999
Downstream line rate (kbit/s):
25542
Maximum upstream rate (kbit/s):
6703
Maximum downstream rate (kbit/s):
25326
Upstream noise safety coefficient (dB):
16.8
Downstream noise safety coefficient (dB):
5.8
Upstream interleave depth:
0
Downstream interleave depth:
0
Line standard:
VDSL
Upstream line attenuation (dB):
44.5
Downstream line attenuation (dB):
19.1
Upstream output power (dBm):
1.4
Downstream output power (dBm):
10.3
Channel type:
None

Thanks for any help

Is this your first FTTC connection?

Was this a self-install, or an engineer install?

The downstream line attenuation at 19.3db is better than mine (at 21.3db), and I sync at 58mbps so, in principle, I would expect your line to be able to do better than 25mbps. There are all sorts of reason why it might not, line imbalances, differences in power masking at your cabinet and so on. However, there's one thing that is worth eliminating straight away and that is any impact caused by internal phone wiring in your house. VDSL is rather susceptible to that. Note, it doesn't matter if anything is actually plugged into any of the extension sockets, just that the wiring is there.

If you do have extension wiring, and have a modern master socket, then it's worth doing a simple test. Remove the faceplate (which isolates any extensions) and plug the router into the test socket. If it gives a substantial improvement, then it's worth looking at optimising internal wiring. If that doesn't yield and improvement, then only an engineer is likely to be able to make any improvements as it requires specialist test equipment and moving pairs and the like.

Yes 1st fiber and it was a self install.

Thanks about the comments about using the master socket test socket, will try that out. My mastersocket is in the landing with no power points and stuff so can't leave it plugged in there. But will try out the speeds over the weekend plugged into the test socket by using an extension lead to power the modem.

It's often the case that there's no power socket next to the master. As you are clearly connecting via an extension socket, then it's quite likely there will be a difference. There are all number of remedial things that can be done. Some are trivially easy. Disconnecting the ring wire to all the extensions on connection 3 often makes a large difference. Others are more involved including filtering at the master and providing a dedicated VDSL feed over cat 5 cable.

However, the first thing is to see if it works better off the test socket before making any changes (although the ring wire trick is always worth doing anyway).

Ensuring the OP means the test socket, not simply the master socket.

I was kind of wondering this myself. but as someone has said. They have a higher line attenuation but can sync at a higher speed.

I would just like to ask if the connection I'm getting is good for the line stats or should it be going faster?

3. Firmware version: Software version 4.7.5.1.83.8.173.1.6 (Type A) Last updated 14/05/14
4. Board version: BT Hub 5A
5. VDSL uptime: 8 days, 20:40:36
6. Data rate: 19872 / 56801
7. Maximum data rate: 19875 / 56005
8. Noise margin: 6.0 / 6.6
9. Line attenuation: 0.0 / 13.1
10. Signal attenuation: 0.0 / 13.1

I was getting a solid 75Mb line when I first started, but then after 4 weeks, it dropped to 53Mb. I'm litterally about 200m from the Cabinet. I've heard people say that it is distance dependent, but I'm guessing that this issue could be crosstalk?

A couple of weeks ago, it shot up to 63Mb and stayed there for about a week, but then shot back down. Can anyone shed some light as to why this may have happened? By the way am on Cabinet 26, Postcode WA7 5YN. Thanks!

Is this in relation to the original poster or my post? If it is my post then mIne doesn't. Only can get Home Hub 5 stats when I put the old 192.168.1.254 in the browser.

It was to you, as per the header link smile.

As you can see, the info available from an unlocked Openreach HG612 modem is considerable more useful. Tells us all about the interleaving regime, latency delays, bin range usage and so on.

They help diagnose problems.
