Speed Issues and PN Reply

About 2 weeks ago was upgraded to 8mb. Speed varied during the 10 days but then generally settled at about 4.6mb - 5.4mb. Over the last two days speed was down to 1.8mb using PN Speed tester, Speedtester.net and the new BT Performanace tester. Raised a fault this morning and the reply was that 1.8mb is within accesptable BT limits. Surely after getting 5.4mb there must be a fault somewhere and yet PN dismiss it as acceptable, without offering any further assistance. Was this an automated reply and further tests will be carried out or what.

I'm afraid that's the way it is.

With sync rates such as you mention, your stable rate will be 4 or 4.5Mb, and that will limit you anyway, so on a good day you should download at 3.5 or thereabouts. You will never get the full theoretical speed due to overheads, system congestion and a range of other factors.

The Pn network is overcrowded, so at busy times you will get a much slower rate than, say early morning. Add to that the overcrowding situation on the BT network, and you will see that quite a few things are stacked against good speeds.

My stable rate is set at 5Mb. About now (10 am) I can get 3.5 to 4Mb, but in the evening, this comes down to below 1Mb.

Look around on the forums - this question is quite a common one.

Good of you to respond.
My stable rate is 7000
Does this affect you answer in any way
Thank you

No.. It is not acceptable..

The MSR value is solely used to determine when a drop in sync speed would be considered a fault*. It is important to understand it is not a guarantee of speeds that you should expect for your 'up to 8Mb' connection and that Max is rate-adaptive, meaning your speeds will vary throughout the lifetime of your connection. We do not publish your MSR value as part of your Max service.. think of it as for administrative purposes only. If you would like to see what data transfer speed you are receiving on your connection please see your BRAS Profile.

*BT will accept a fault report if the line rate drops by 30% or more from your established MSR, this is said to be below the Fault Threshold Rate. e.g. if the MSR during the first 10 days is determined as 5000kbps, a fault can be reported when your sync speed drops to 3500kbps or less..]

Therefore do not accept the fobbing off.... Mind you be prepared to wait.... and wait and wait..... and enjoy a game of tennis in the meantime

I now see I'd misunderstood the speeds you gave. I'd assumed the higher ones were sync rates, but now see that they are all the results of speed tests.

If you're getting up to 5.5Mb on a 7Mb stable rate, that's about what you could expect - possibly another .5Mb or so with the wind behind you if you picked you time right..

And this will certainly come down to 1Mb or less when the network is really busy, regardless of your stable rate.

I don't know for sure, but would think that you'd get something similar with other ISPs as they are nearly all doing the same as Pn and shoving too many people on to too little capacity.

And on top of that, the creaking BT network can't take all these people trying to get up to 8Mb either.

So in summary, I think you're getting about what you could expect.

ps I've just run a speedtest at 10.58 am and got 4242.

I dont think he is gpattison...

He had a higher rate, which has dropped.... presumably due to disconnection, etc and therefore the MSR has dropped. However this should return to around the original within 3 days if the network sees the disconnection/slowdown as a blip. If it doesnt then BT need a nudge via PN.

Similar has happened to me .... rocksolid 1.5mb for months with snych 2.3 to 3.3mb, now dropped since week ago last sunday ticket open, wading through the inevitable responses from PN and awaiting their action.

OP should look to reboot router once a day to help nudge his speed back to the orig stable rate....

The above all relates to sync speeds, not throughput. The OP's comments seem to relate to throughput, since they refer to speedtests not the sync rate being reported by the connection.

The OP needs to clarify exactly what they're refering to but, if it is as I read it, what they are seeing is exactly what is to be expected.

BT xhanged the BRAS setting at midday yesterday to 2272kbps. The BRAS is BT's speed restriction on your line, which can drop within 75 minutes if they notice your equipment resyncing at a lower rate.

Whilst, if you maintain a higher level of sync, your speeds should return to the level they were at with the next 3 days. This is not a problem. It is BT's Dynamic Line Management erforming as it is designed to.

He said earlier his stable rate was 7Mb.

If it's dropped and is not now 7, then that will obviously limit his speed, and as James says should work its way back up if he goes without line drops for a few days.

His stable rate has also dropped to 2000, in line with the BRAS decrewase to 2272.

Yes it has dropped from 7000 to this

Your current broadband speed is 2000 Kbps
