Was on 55/10 now on 40/10

I was on 55/10 speed profile, however yesterday (18/03/19) I noticed the line re-connected and I was re-synced on Down 40000Kbps / Up Stream : 9997Kbps.   I re-contracted back in around October 2018 and was told I would stay in 55/10 speed profile.

 

I have also noticed I've lost G.IMP on both far and near ends, and my ping has increased from normally around 12ms to 22ms, this happened exactly the same time my speed profile changed above.

 

Can a member of the Plusnet team please look into this.

 

Many thanks

Jason

Thanks for getting in touch.

I'm sorry to hear that this has happened.

I've placed an order to move you back onto 55/10 which will complete tomorrow.

With regards to G.INP, unfortunately, each order placed causes DLM to reset your line. You may get it back eventually but I'm afraid I can't give an exact timescale.

Re: Was on 55/10 now on 40/10

Thanks for your help on this.  I have a related question however.

 

Now i'm on 40/10 I notice in my Draytek that sync speed is Down Stream : 40000Kbps / Up Stream : 9997Kbps.   Previous when I was on 55/10 the sync speed was whatever the line would take, this would normally show as around 65000Kbps down and 16000Kbps up stream,  to be clear again i'm referring to modem sync speed and not transfer limits on actual data.

 

Is there something that's very recently charged so customers modems will sync at the exact speed necessary,  for example now i'm going back to 55/10 will my download re-sync to 55000Kbps, or will my modem re-sync at it's fastest possible as it did previous on the 55/10?

 

There were some advantages to having the modem only sync as fast as necessary as it increased SNR on the line, also the QOS on my Draytek works better as it's calculated from line sync speed and not bandwidth.

Hi @JasonMassey,

 

To be honest I'm not 100% sure on this, however I believe that the down stream on your router should re-sync to 55000Kbps once the modify has completed, rather than back to the 65000Kbps that it was at previously.

 

@Gandalf has made me aware that your router was previously showing a higher sync speed as you were incorrectly provisioned on 80/20 fibre rather than 55/10. Once the modify order completes, your router should re sync at 55000Kbps down.

Re: Was on 55/10 now on 40/10

@JasonMassey I assume you were at some point on the legacy 40/20 product, which was actually a BT 80/20 provision but throttled to 40 downstream by a PN profile. When these accounts were changed to 55/10 some like yours remained on a 80/20 provision and throttled to 55 down. Hence your sync speeds. The recent change will actually change the provision to a BT 55/10 provision and will limit your sync speeds accordingly as @EmilyD  says.

As you mention, this will likely increase your noise margin and thus give a more stable and error free connection.

Re: Was on 55/10 now on 40/10

MisterW,  thanks for your response.

 

I have had Plusnet fibre since 2013 and use to have a legacy 40/20 that was changed to 55/10, so you are correct.

 

I'm so pleased you have confirmed BT will provision line speed at 55/10, as previous my SNR was unnecessary high and as also mentioned it was messing with my Draytek QOS settings.    So again if the line (sync speed) is being provisioned at 55/10 this is perfect.

 

Many thanks

Jason

Re: Was on 55/10 now on 40/10

Cool. Fingers crossed things go smoothly tomorrow when your service is moved to 55/10.

Feel free to let us know how it goes or if you need any further assistance.

Re: Was on 55/10 now on 40/10

My line sync speed has changed since yesterday, it's currently showing Down Stream : 46674Kbps / Up Stream : 9997Kbps.    I use to sync at over 60000Kbps down, i'm not to bothered about this however as I've noticed my SNR ratio has significantly increased and value what should be increased stability.

 

However there is still an issue.    When doing a speed test my download is maxing out around 36Mbps, this is just as it did when syncing at 40000Kbps yesterday.   It looks like there is still some speed profile restriction in place despite todays increase in sync speed can you please look into this.

 

I have also attached a couple of screen shots showing bandwidth history results, on the end of those results is a test today showing download speed is still what is was when syncing at 40000Kbps down.   As mentioned i'm not to worried about getting the peak 55MBps back (as I value the increased SNR), however if you could please removed the speed profile restricting me around 36MBps.

 

Many thanks

Jason

Hi Jason.

It looks like your account is restricting your speeds at a previous IP profile.

I've updated this for you now, can you reboot your router letting us know how your speeds look afterwards?

Re: Was on 55/10 now on 40/10

Gandalf,

 

I have just restarted my router/modem and Speedtest.net is reporting around 43Mbps down, so this is now in line with my sync-speed.

 

Regarding my drop in sync speed, as mentioned i'm not overly concerned as I've had a large increase in SNR margin.   I'm hoping G.INP comes back mainly for ping times, however I expect G.INP would increase my sync speed again.

 

Many thanks

Jason

Hey Jason, I'm glad to see your speeds have increased now.

Hopefully they increase even more with time. Let us know if you need any further assistance.

Re: Was on 55/10 now on 40/10

An update on this.

 

My line speed is on Down Stream : 54997Kbps / Up Stream : 9997Kbps, I also have my G.INP back so ping times are back to normal.   So this is fine and i'm very with this.

 

However there is still a cap on my line,   I'm getting around 48MBps down, obviously I won't get 55MBps due to overheads, however it should still be around 51/52MBps range.

 

Testing has been done with network cable, I have also disabled QOS on my Draytek to ensure QOS was not effecting anything. 

 

Is it possible someone can look into, and make sure there is no speed cap in place?

Hi there @JasonMassey,

Thanks for getting back to us.

 

I have tested your circuit today and it is showing a throughput speed of 52.5mbps and there are no outstanding faults. There are also no speed caps in place to stop your speed from achieving the above speeds.

If there is anything else we can help you with please let us know.

 

Thank you.

Re: Was on 55/10 now on 40/10

fwiw, when I recontracted 9 months ago, my line was re-provisioned from 55/10 to 40/10.  It was later corrected and 55/10 was restored, but like yourself, I have noticed speedtests now only return around 49 Mbps instead of 51/52 Mbps even though the router is synced at 54,933/9,999 kbps and ping times are around 9ms.  I thought it would eventually return to 51/52 Mbps, but there has been no improvement.

I can only speculate the loss of 2-3 Mbps may be due to how the 55/10 was re-provisioned.  eg. perhaps 'best stability' instead of 'best speed' ?

Re: Was on 55/10 now on 40/10

Bill888,

 

What you describe is exactly what I have,   i'm getting around the 48-49 MBps so i'm loosing in range of 3-4MBps on the downstream.

 

Briefly I was provisioned onto 40000Kps, at that speed I was getting 38MBps down, that's a 5% loss due to overhead that is about correct.    However on 55000Kps sync peak download of 49MBps is a 12% loss and is higher than it should be.

 

I'm running a Draytek 2860n with latest firmware,  yesterday disabling QOS and firewall and investigated other settings,  I'm pretty certain the restriction is not inside my Draytek.  

 

Bill888, what router / modem are you using?
