PN Current Line Speed

As far as I am aware that plusnet up to 38/2 get current line speed set at 40 Mb but why is plusnet up to 76/19 get current line speed set at 78 Mb. Doesn't make any sense at all. Should be set at 80 Mb.

My current line speed was set at 80 Mb for the last 6 months and now Plusnet set it at 78 Mb. What is going on? Why can't they just leave it alone. I have rang up tech support but they refused set at 80 Mb because it won't allow it. That's loads of rubbish, I seen my other friend's Plusnet current line speed at 80 Mb for a year now!

Getting fed up with this silly current line speed.

Before: BT IP: 77.35 Mb & PN set at 80 Mb throughput speed 75.45 Mb Smiley
Now: BT IP: 77.35 Mb & PN set at 78 Mb throughput speed 73.45 Mb Angry

Tragic.

If my throughput dropped to 97.35% of what it should be (and always was) I think I'd call my ISP and ask if they could apply a 2.65% discount (53p/month) off the full price for the next 2 years.

My heart bleeds for you.

Estimated line speed:
69Mb (This may vary between 49.9Mb and 69.8Mb) - Checked on 2015-12-28 09:41:18
Current line speed:
29 Mb

Opening this OLD can of worms again!

Oh dear, now you know what it's like to be shafted of 2 Mbps or more , I recall you arguing that their secondary IP profile didn't throttle their customers connections when the sad reality of it is that it does , just because you where lucky enough to have escaped this until now shouldn't really mean you go into i must defend my isp mode

Aren't the changes down to Wholesale changing the product portfolio? Due to fibre uptake getting faster and wider, they speeds will gradually slow down that they can offer as a maximum.

Same happened with ADSL2+ it was originally upto 24mb, and now it's upto 17mb. Was only a matter of time with fibre.

That's an advertising regulation thing and doesn't affect the real-world performance at all. I agree crosstalk does, but not in the way the OP is complaining about.

Crosstalk mainly affects the sync speed, not the throughput in relation to it, unless horrendous error rates are caused. Whereupon DLM drops the sync rate to reduce them.

What a shame, be thankful you can get anywhere near that speed, I know people who are still using dial-up.

The faster we get the faster we want.

Nope, not at all related.

ADSL2+ connections are largely sold at lower "best case" speeds as a result of some Ofcom rules on advertising (the advertised up to has to be achievable in so many 5 of cases) and companies making regular broadband seem less attractive now than Fibre.

Fibre speed advertising has nothing to do with changes on wholesale - they're still offering the same products (and will add one soon), and it is still entirely possible to achieve full 80/20 sync (I still do, always have).

Don't be silly, it makes absolutely no difference as your IP profile is 77.35Mbps.

Not for the first time IIRC, you are mixing up allowed advertised throughput speeds with actual product sync speeds.
For the 80/20 product a 78Mbps Profile is correct if you are syncing at 79,999.
On the 40/20 product, it used to be that you'd only get a profile between 38 and 40Mbps if your sync speed is sufficiently high above 40Mbps. On 40/10 and 40/2 products I'm seeing evidence that the sync speed is limited to 40000kbps even if the line would go faster, so the max.profile will be 38Mbps.
Has it not occurred to you that perhaps Delta reports have eventually come through the system and automatically set your Current Line Speed to the correct value?

It does the use of Pn's profile and traffic management results in a 2mbps loss in throughput if you sync at the full rate, it's only those who have a 80mbps sync that this affects,more noticeably, my speed was less when with PN and the changing of their profile from 78mbps to 77.2 or 77.3mbps also impacted throughput further, they claim only a reduction of 200kbps, but in reality it's 2mbps ,than it is has been since moving to Zen

I thought the suggestion was that everyone lost 2Mbps, not just those who sync at the maximum? I don't think anything was ever proven anyway. The OP should count himself lucky that it's set at 78Mbps then, because I would have expected it to be 77.3.

In reply to a post by tommy45:

........... they claim only a reduction of 200kbps...........

No they don't. The IP Profile is rounded down to the nearest 200kbps to set the Current Line Speed (on FTTC and also FTTP IIRC - on ADSL it's to the nearest 100kbps). That is not a claim about any reduction in throughput speed. But the net effect of having a Current Line Speed and good traffic management on FTTC may well result in reductions in throughput speed of circa 2Mbps, however

Oh dear, I feel so sad for these people that lose 2Mbps throughput on an 80Mbps connection when there are poor individuals around on 20CN connections (even 21CN) who struggle to 2Mbps sync speed
In any case unless you are actually maxing out the connection all the time I wonder who would actually notice this in practise. If you had a house full of students then the connection could perhaps get maxed out, but I'd say that in those situations good traffic management would be essential to protect the real time applications otherwise everyone would be moaning.

I might be selfish person, but I don't want to lose 2Mb on the throughput speed if PN set the current line speed at 77.2 Mb as if it was set at 78 Mb I would get 73.5Meg throughput but if it was set at 77.2 Mb I would get around 72.5Meg throughput. Massive loss!

PN Current Line Speed: 80 Mb = throughput 75.5Mb
PN Current Line Speed: 78 Mb = throughput 73.5Mb
PN Current Line Speed: 77.2 Mb = throughput 72.5Mb

Sarcasm I hope. Tiny, inconsequential loss that would never be noticed in practice.

Would your browsing and emails appear on your monitor any quicker with an extra 2mbps?

At the end of the day they are shafting their customers those who can get the max available sync speeds loose the most

(lose)
And it is the least important loss.

It was explained long ago anyway.

Basically they have their their traffic management system devised years before FTTC speeds were dreamt of and mass streaming didn't happen. This necessarily involves some buffering while priorities are assigned.

This doesn't basically affect latency much at all, though must do to a slight degree, but with FTTC speeds allied to hugely increased throughput volumes inevitably results in a top-end throughput limitation.

I might be consider switch to AAISP Home::1 80/20 because soon they will become unlimited usage!

Give it a few months and you will moan about them, you have been through so many providers, I am surprised there is any left for you to try.

Errr - no they don't?

Or have I missed something?

The new unlimited at £60pm is TalkTalk Business with no PSTN phone service. Only VOIP at extra cost - but I think that can be taken from other VOIP suppliers.

Unless an upgrade to Home::1 has been announced since then and I've missed it.

I think I better off buying leased line 1:1 fibre 300/30 from Openreach! My own provider!

That might not be quite correct .

For instance, see these prices.

2MBps/2Mbps at £152pm, (I expect plus VAT), might be slightly above your budget. Never mind 300Mbps/nnn Mbps.

is a 1TB usage limit, capped to 3mbit/sec if the user goes over.

Well out of max's price range tho, he will stay on his retention plusnet deal.
