Actually my current profile is higher than my sync.

Would you care to post the results of a BT speed test, showing the IP Profile, and also the current connection speed shown by your modem? Not something from a while ago, bang up to date for both please.

The VDSL spec doesnt even require IP profiles its something unique to how BTw have designed their network, once you understand this ...

Thanks for the gratuitous and silly insult - Merry Christmas to you too!

... then you realise they are likely a script added on top of the protocol and then obviously that script could be adjusted.

And that would magically make an Openreach product give a higher sync rate than the product spec?

I am not saying this has happened

That's good to hear

... but I am at least open to saying its possible.

No it isn't.

I am still hearing for your reasoning as to why its happened or maybe you are as silly as batboy and think they setting profiles above the product spec to fix a invisible problem?

?????????????
Would you care to read what I keep trying to drag out of BatBoy, despite your idiotic thread-hijacking suggestions of wildcat ideas about the reasons for higher than 80Mbps IP Profiles that both of you have failed to substantiate as existing?

My original reasoning was either a fault or that these people were possibly syncing above 80mbit and having higher profiles set, probably in preparation for BT allowing higher speeds.

That is about the first sensible thing you have said in the thread. It does at least acknowledge that higher profiles are being set because of higher sync, not as cause of. Or at least, I hope that is what you are acknowledging.

IP profiles are set by a script, that script can be changed at any time, whilst you seem to think its something that is impossible to change.

Which is why I have completely ignored on my website^* and in any post I have ever made on the subject that the 20CN, WBC and FTTC IP Profile setting is different? You seem to have stolen some of BatBoy's myopia - as opposed to your suggestion that I am being as daft as him in this thread.

So its certainly not impossible for a script to even set it higher than a sync speed.

Of course it is possible. What effect do you think that would have, other than for a variety of reasons causing packet loss?

Edit: * - which reminds me my update for FTTC IP Profiling is in fact still in draft and unfinished .

Here is my BT speedtest result 2 minutes ago:

Download speed achieved during the test was - 70.15 Mbps
For your connection, the acceptable range of speeds is 16 Mbps-0 Mbps.
IP Profile for your line is - 87.5 Mbps

The Modem (hg612) gives :

Attainable rate (kbit/s) 86752
Line rate (kbit/s) 79999

Edit: Immediately after posting the attainable rate went up to 86980. It is constantly varying between the two.
The Plusnet current line speed is 78Mb.

The fixed break is still there!

But so far as I can tell from BatBoy's enigmaticism, that isn't the break that has been fixed.

Hi Freddy,

At last a voice of reason .

That is very wierd. What does your Plusnet Current line speed say?

Not only do we have that high IP Profile, but it isn't even what you would get from the Attainable rate. That would be an IP Profile of 83.96 or 83.97, so it is far higher.

The expected IP Profile from your sync looks to be 77.4.

At least we have one other piece of useful information - unless maybe you have re-sync'ed for ages like the rest of us, which is that your sync is not higher than the IP Profile, and isn't even above 80Mbps.

I don't suppose you fancy a re-sync of the modem some time during daylight tomorrow, to see what turns up? Your IP Profile is what would be earned by ~ 90.4Mbps sync.

In reply to a post by RobertoS:

78 Meg, he says.

Indeed he does.

That is also odd, seeing as it is normally rounded down to the 100kbps below the BTW IP Profile.

Hi Season Greetings to All
Sorry don't mean to reply to you personal but the system of the forum seems only option to reply is if i hit the reply button from some post so i did to last poster

TO TOPIC
I have seen members stating profiles ,synch speeds higher whatever etc (which all you right)
But forgotten ONE major detail


I was with TT fibre optic boost (now back to adsl) cos moved house) and they had me at capped 40/2 packet while the line was running faster (17a profile)
Now each isp is advertising up to 78,76 ,72,70 mb etc speeds, which at that point must be capped by the isp

How can get a higher speed no matter profile & synch if the line is capped?????
The case is simple:
At some places they must uncapped speeds

I am with Crysalis what believes

Perhaps they testing what the 17a profile can give uncapped
(Remember VM has 120mb in many areas so may be nice from BT to advertise up to 100mb - that what gives the 17a profi)

EDIT
Do all of you a simple test
Leave it few days to get stable line (all FTTC users know this by now) then after few days do a reboot
Probably It will go up to 90mb
Thanks & Carry on arguing (with respect to all, my last word arguing is like joking & not mean bad way)

I think having a profile higher than sync will have no ill affect as its end to end that dictates things not intermediate routers (unless they congested or throttling). Obviously BTw and isp's will have their own internal reasons for profiles but I dont see them as essential. I think one such reason is it makes bandwidth management easier as profiles as you said are 'typically' auto set based on sync speed and then these can be used like entanet used them years back when they published the % of user's on different profiles.

So whilst I think its possible for the scripts to be configured that way, I do also think its extremely unlikely it has been done so deliberatly, but it is possible its been done accidently aka a bug.

I wont bother with screenie for my profile because i believe mine is higher due to been stuck not the same as these other guys (is still 77.43).
