Actual speed vs synch speed

As I type this the router indicates 6331 kb/s. Speedtest indicates 4.76Mb/s

It seems slightly slow - but I'm not sure. Is this about right?

For completeness here's the stats from the router:

The speed was wandering around

http://www.thinkbroadband.com/speedtest/button/14037...

Using WiFi? Or the net was still busy just before midnight. The test should be more straight e.g.
http://www.thinkbroadband.com/speedtest/results.html...

A bit of a wobble at the start but settles (common due to AV/firewall software)

In your case the error counters may be partly to explain for the slightly wobbly speed. Resolve those and you might push marginally better speeds

Hi rob54,

Feel free to drop me a PM with your username if you'd like me to check your connection from our side for you.

PM sent thanks.

Mr Saffron,
Test was not wifi (PC is connected with network cable), though phone is wifi so I don't know if any data was flowing to/from that then.
I have PMd thatadamwalker as he suggested.

I often find if router synchs at a lower speed, the speed test is then a higher percentage than this test.

you are getting a lot of errors, which is what slows it down.
the snr of just 2.8 does not help this.
what you should have is a lower sync, without errors, (also interleave might help !)
if it were my line I would turn the router off and on a few times to force the line management to look at it.
I bet you get quite a lot of dropouts/resyncs too

I do get a lot of dropouts and resynchs. Dropouts (if that's what it is) was happening whilst the router stays connected (internet activity just stops). It seems to have improved and getting no activity stops since I put specific DNS addresses in as per the Plusnet advice re manually assigning these. Maybe coincidence i.e.

Preferred DNS server: 212.159.13.49
Alternate DNS server: 212.159.13.50

Today the stats are:
Uptime: 1 day, 0:13:52

and speed test http://www.thinkbroadband.com/speedtest/results.html...

So a better percentage and less wandering about!

Sorry to drag this thread up again, but I had a fault fixed on the phone line two days ago. A new vdsl2 socket was also fitted.

Problem is Synch speed is gradually coming up and was virtually unchanged on router restart at 4544kbps today. But the actual speed is only 2.53 Mbps see http://www.thinkbroadband.com/speedtest/results.html...

Any ideas? Should I go back to Plusnet now or wait a bit?

https://portal.plus.net/my.html?action=data_transfer... is probably the reason
Either wait for it to sort itself or phone up

Thanks. Err I know you are on the Plusnet forums (assuming you are the same Oldjim), but how do you know how to get information about my connection?

What he means is, "Check it" .

I don't - that was the link for you to check
Every Plusnet user clicking on that link will get to their own information after logging in

Oh OK
So it's this:

Telephone number:
XXX....
Phone exchange:
SANDERSTEAD
Estimated line speed:
6Mb (This may vary between 5.5Mb and 7.5Mb) - Checked on 2014-07-13 01:46:51
Current line speed:
2.7 Mb

Yup
and the current line speed is what you need fixing - it should be 5.5Mb

The Current line speed is used by Plusnet to limit your download speed. It is supposed to be the IP Profile in kbps rounded down to the 100Mbps below the actual.

You find the IP Profile by running the BT Performance Test and continuing to the Further Diagnostics.

The PN figure should adjust within hours of a profile change. If it doesn't the best thing to do is ring them and get it set correctly.

Overlapping posts .

But you've missed a sync drop to 4544kbps. So IP Profile I expect is 4Mbps, and Current line speed should be 4 or 3.9Mbps, depending on how they handle a 4007kbps detailed IP Profile.

In reply to a post by Oldjim:

Yup

That is about what it was before the problem of noisy line was fixed (see my first post in the thread). I will have to contact PN again. Maybe the Openreach guy did something of course Seemed on the ball I thought.

That gives
Download speedachieved during the test was - 2.58 Mbps
For your connection, the acceptable range of speeds is 1.2 Mbps-4 Mbps.
IP Profile for your line is - 4.01 Mbps



Edit:I didn't restart the router or disable security like it said do

All those red instructions are rubbish. Following them can change the situation, making diagnosis of any real problem even harder. So don't worry about that.

We could do with the full router stats again please . IIRC your last lot showed you on ADSL2 instead of ADSL2+ for instance.

Red instructions? Anyway - stats:

Edited by rob54 (Sun 13-Jul-14 22:54:38)

There probably wouldn't be much difference, as the attenuation may go up by about 3dB on ADSL2+. In either case you will get much more once the SNR Margin comes down to a more normal figure.

You can either wait, or see if they will reset the line for you. Seeing as it could be 10-14 days for 3dB, then the same for the next three, I think I would get onto them.

Hi there,

Sorry I've not been able to get back to you before now.

It looks like we've just been waiting to hear back from you re 87906949 as to if the phone fault was fixed.

Re your connection speeds I've just submitted an SNR reset which should hopefully lead to some improvement within the next few hours.

Adam,

Have replied to ticket thus:

Hi Adam,

Thanks for getting back (via TBB forum)

Sad to report though that although the line (synch) speed is up to where it ought to be with its lower SNR, the speeds as tested is unchanged (see http://www.thinkbroadband.com/speedtest/results.html... It surely can't be to do with Openreach and the new VDSL2 socket they fitted (apparently they are doing this to everyone they go to) or the router would not see 6429kbps.

This is tested at the PC with an ethernet connection only. I get a similar result still using speedtest.net on a mobile.

What do you suggest?

Don't forget the Plusnet Current line speed only updates two or three times a day.

Seems you were right Bob. Router now at 5867kbps, speed test 4790
http://www.thinkbroadband.com/speedtest/results.html...

Judging by the drop in sync speed you rebooted the router. That may have triggered things. IP Profile will be 5.2Mbps I expect, with Current line speed 5.1Mbps.

No I didn't reboot it. Must have happened sometime yesterday evening. Speed test currently 4760.
