Stuck profile?

Could someone please chack ticket: 50709544

Seems as my ADSL2+ upgrade is complete as sync'd at 16,164 but my line speed in plusnet panel still says 6.5mb. Is the profile stuck?

Many thanks

Thats been sorted for you now.

Shout if you need us.

Hi M

Thanks for that - It's now updated in the Control Panel to 20mb but still download speeds are 6.5mb. Also, the Bt Speedtester says it is unable to do a test on my line at this time.

would it be beneficial turning the Router off and then back on again? I heard that during the training period this helps but not to do it too often as it could cause a lower sync rate. Do you think this may help?

Thanks

He said he is getting 16Mbps plus, which means the router has picker up on the ADSL2+. The IP Profile does not affect the router.

There should be no reason to re-sync. But! Stranger things have helped .

Restarted router and now sync'd at 14,904 and Speedtest.net reports 12.6 download so something must have worked!!

Everyting seems ok now - BT Speedtester now working and I'm getting 12.5meg down which is double what I received before today so I'm happy!!

Cheers all

Could just be the Plusnet reset hadn't filtered through to where it matters. There is a bit of confusion about how their system works, as they often refer to "an imbalance" in the system, but haven't said where the rogue setting is.

I thought BT only held it at the BRAS, from sync information received there from the MSAN. Then there is the PLusnet Current line speed. Then according to what has been said by PN reps, even though those two may agree, there is a third point. Hmmm .

Not long ago it seemed that was the MSAN, but I have grave doubts about that.

From what you have just experienced, and from the fact PN always warn of some delay between their fixing the Current line speed and that fix having any effect, it begins to look as though that is (normally) set from the BT info feed to them, and then at some stage updates the PN mechanism that actually throttles to the Profile value the speed from them to the MSAN.

Whatever, as the youff used to say, try a reconnection during daylight, and with luck you will get the 16Mbps sync back, and a profile to go with it.

hi roberto

I'll try another router reset before I goto bed. Would u recommend another in the morning if the 16meg isn't back?

thanks

I think basically we are in agreement that a resync could help, even though it shouldn't. He did one, but I'm not convinced that is where the improvement came from, because of the strange info that comes out of PN.

Night-time sync's are almost always slower than daytime. That's why I said do a daytime one .

No point in one tonight. You may get a bit more than now, probably a bit less. Unless there was a lot of noise when you got the 14.

haha - my tired eyes must have read 'during daylight' as 'during night'!! I thought it wasn't good to restart at night.

I'll try another restart mid-morning tomorrow then and report back.

Thanks again for your help

They can help, as it creates a new trigger event that will wander through the various backhaul systems, and may flush out an out of date setting.

If a router lets you drop the PPP session and reauthenticate, rather than a resync that should do it.

But where is/are that/those other setting(s) Andrew? No-one seems to know. There is the BRAS, there is the PN copy. They were both OK and sync was 16Mbps, but still slow until he did the re-sync.

Unless my latest theory about the PN system is correct, and the gain in speed was just a coincidence and had already occurred.

In the past PN have said that when this happens they have to trigger some sort of correction of an "imbalance in the systems", implying within BTW not themselves. But as this phenomenon doesn't seem to occur with any other ISP, .

Hi RobertoS,

There's two bits of kit on BTs side that seem to hold line profiles independently (BRAS and MSAN) plus the profile on ours, so mismatches can occur across both. From what I've seen one of either the BRAS and MSAN report their profile to wcr which is the reporting system we use to get our profiles from, I think that's the BRAS that does that. Then the MSAN is (I think) what reports the line profile on a BT speed test result.

It's easy enough to sort when both bits of BT kit are reporting the same and our profile hasn't updated, which if I'm honest is the case most often when there is a mismatch. However sometimes the BRAS and MSAN don't match up and that's when things get fun.

Sometimes an SNR reset will sort it, but if not it means raising a fault unfortunately.

It'd be interesting to know if any other ISPs are noticing this happening, but even if not I assure you I've personally seen and dealt with several mismatches across the exchange kit... I think there's even been one or two on these boards?

Hi Orbrey,

I don't wish to hijack this thread, so just a quick query:-

Should Plusnet's Current Line Speed also regularly adjust for FTTC connections to match BT's IP Profile/BRAS rate?

My Current Line Speed is always reported as 37Mb in the Plusnet Portal, but I have not synced over 30Mb since July.

I have seen a few other Plusnet users reporting some slight glitches with the FTTC profiling system.

My IP Profile is currently 25485 k.


Paul.

Thanks for that Orbrey . Ties in with what you or one of your colleagues said a while back.

When I have a bit of spare time from being a pain here I'll see what more I can find out. Your explanation makes sense, but I'm not convinced. Even you are only saying "that seem to", and several "I think"s.

But something up somewhere there definitely is - we agree on that.

As for the PN line speed occasionally not getting updated, that is a long-standing problem. A nuisance but easy once spotted, as you say. My gut feel is that is something at BTW not yourselves that isn't quite right.

Quick update on this. Did a reboot of the router about and hr ago and it connected at a slightly higher rate of

Stats are below. Quite a few errors but line seems stable enough and I'm more than hapy with thr speed as it's practically double whta I had before the upgrade ysterday.

Attenuation seems to have dropped slightly since the upgrade - used to be 30-31. Was told it would probably go up 3-4 but I'm not complaning! Just did a speedtest and got this:

Hi there,

It should do, but the equipment that generates the profiles is in the green box rather than the exchange and we don't have any sort of control. I'm not sure why the profiles aren't updating in some cases but we're feeding back on it and expect as the technology matures things will get better.

If you could advise of a ticket ID or PM me your username I'll take a look at your account and see if there's anything we can do?

Fair point, that was badly phrased. I'll try and split out what I know for sure.

The BRAS and the MSAN both hold a line profile, and both are based in the exchange. I've seen speed test results that don't tally with the profile seen reported in WCR, so I know that those bits of kit are (or can be) independent. The only bit I'm unsure of there is which kit reports to which system.

There's also the fact that the diagnostic systems we have access to allow us to run a consistency check test that reports on the profiles on the BRAS and MSAN, and will advise if a mismatch is found.

Those things I do know for definite
