Speed loss after upgrade.


[link to this post]
 
On the 28th of this month my line was upgraded, and I quote.


"At BT, we are committed to giving our customers the best levels of service and that includes the speed of your broadband connection. We have invested in a new broadband network that will help us offer faster speeds and we will be transferring your BT Business Total Broadband service on 016********8 over to the new network on 28/08/2012"


On the morning of the 29th speeds did increase from a rock steady 6megs up to around 12megs. but during the afternoon the speed decreased to a miserable 2 megs and settled down to 5\6 megs since. I use a Billion Bipac 2300N router which is ADSL2+ capable.


Is there an explanation as to why this might be?

Some stats from the router might be a start, sync rate, attenuation, snr and the like.
If you could copy and paste these in a reply.

Switching to ADSL2+ means the start of a new 10 day stabilisation period, so your connection may fluctuate for a few more days, although in practice the new MSR (Maximum Stable Rate) and FTR (Fault Threshold Rate) are usually set well within the 10 day period.

However, you won't be able to raise a fault on your line until the 10 days is up.

Thanks for replies fellas, I'll wait out the 10 day period as suggested Jaggies and if still low I'll post router stats as you suggest Zarjaz

And worth pointing out the setting of MSR and FTR do nothing to actually limit the sync speeds at all

The line remains in noise margin training state until you cease it

Well those show a 16Mbps connection. Please can you copy and paste the results from a BT Performance Test. (Not the beta version). The stuff in the text boxes will do, we don't need the graphics.

My broadband basic info/help site - www.robertos.me.uk
Domains,website and mail hosting - Tsohost. Connection - Plusnet Extra Fibre (FTTC). Sync ~ 56.0/13.9Mbps @ 600m.

RobertoS, hope this is what's required, thanks for response.


Download speedachieved during the test was - 2.27 Mbps
For your connection, the acceptable range of speeds is 4 Mbps-21 Mbps.
IP Profile for your line is - 15.82 Mbps

Your Sync Speed of 16 Meg is reasonable (could be about 3 Meg faster).

Your IP Profile is good. Indeed it implies a faster Sync Speed of 18 Meg since your earlier stats. So it looks like it re-synced in meantime.

It's your throughput of 2 Meg that is the issue. Most likely due to contention at exchange or in network.

I'll persevere for a while longer, the other issue I have is losing sync with the exchange, hopefully it'll all settle down given time.

Thank you all for your replies, comforting to know that I can at least get decent speeds.
