BT Infinity Speed


[link to this post]
 
I had BT Infinity 2 for a few days now, do you think the following speeds are good (average speeds shown, performed a few tests at different days/times)?

Speeedtest.net: Download 45-46Mbps, Upload 9-10Mpbs, Ping 16-19ms
BT Speedtest: Download 45-46Mbps, Upload 9-10Mbps, Ping 20-25ms

BT Speedtest reports IP Profiles of 47.41 downstream and 20Mbps upstream.

Using a Draytek Vigor 2850vn instead of the BT supplied modem and HH3.

I did get download speeds of 51Mpbs on the first day when I performed the first couple of tests.

They are pretty reasonable for an ok line.
What was your estimate (at http://www.productsandservices.bt.com/products/broad... )?
What do you see as a profile ( http://speedtester.bt.com/ then go on to 'Further Diagnostics')?

If those more or less agree with the speeds you are seeing, then probably all about right. It the estimate and/or profile are much higher than the speeds you are seeing, then it will be worth looking further.

Also try http://myspeed.visualware.com/index.php for upload speed tests. It has been rubbish for download speed tests recently, but seems to give the most reliable upload tests (eg in keeping with real speeds to a good upload site).

--
Moved (with trepidation turned relief) to BT Infinity 2 for upload speed. Happy BE user for several years.

What package ore you on? 80/20 or 80/10 or to use the marketing terminology 76/19 or 76/9 ?

I would guess from your BT test it is an 80/20 connection.

If so, the downstream seems fine, but the upstream is way under performing. And may have a problem that others have had.

Can you run a series of speed tests, first of all a BT test and then 4 or5 on TBB with Task Manager running on the Networking tab. Take a ScreenPrint of Task manager and then host the image. If I can see that along with your test results, it will tell me if you have an upstream issue.

If he is on any of those packages his result is terrible! It looks more like a 50Mb connection. My connection is 100/10. This is the result I always get.

I wonder if that's just the line characteristics, the OP is getting pretty similar performance to myself , 45 download and 8.9 upload. BT Infinity unlimited is always the openreach 80/20 product. The BT Infinity option 1 with 40gb usage is the 40/10 product.

I think your line might be like mine, about 500 to 550 metres from the cabinet. I'm using an older Draytek 2820Vn with the Openreach modem but the HH3 went into the cupboard the evening the engineer left.

I did get download speeds of 51Mpbs on the first day when I performed the first couple of tests.

I saw 56 once but that was the first day, and after that DLM kicked in and I stabilised.

Try the speedtest on this site (as long as you're not using a Mac) its pretty good now:

If the Max Attainable was around 10Mbps then there would be an upstream sync of a similar figure - anywhere from 9 to 11 Mbps. However as the OP has an upstream sync of 20 Mbps - according to the BBC tester then his max attainable will be in the 19 to 20+++ Mbps range.

If we can see the OPs router stats and a plot it can be easy to determine.

I think you should look again the OP posted he has a 20meg PROFILE (which I also have) but speed testers have reported 10 meg upload. The OP hasn't used a BBC tester !!

I thought all upload profiles are set at the max ??

Infinity does have a better upload, I always get 15Mbps+, plus my connection is not over subscribed or over saturated.....and its totally unlimited, don't even get throttled when I download X amount, which Virgin Medium does. (I use to be a customer of VM, was on cable since the beginning, then they butchered it.) Looks like all online gamers have gone to BT whilst the heavy down-loaders have decimated the cable companies.

Confirm, but for me with my around 9meg upload sync, it also reports a 20meg upload profile. Which is what the OP posted. The OP doesn't have a 20meg upload sync.

Agree - he only told us his profile. He also told us what other speed test sites report.

Given that old Java tester had major problems with showing upload on FTTC services (always under-reported dramatically) I have no idea.

I stated that mine is almost identical and giving the same results on these other speed test sites. So I can guess his sync is similar to mine.

There might have been some issues with Java tester but there were tests on the old tbb flash tester, speedtest.net and visualware.com at the same time which gave near identical results.

There were a large number of tests with the new Flash tester but not logged in so most results are not recorded but immediately prior to the testing these were seen:

http://www.thinkbroadband.com/speedtest/button/13609...

Are four flash tester results which show the 9Mbps upload - And the line has a 20Mbps sync, max achievable of over 24Mbps

So, downstream is a little low, but nothing to really complain about.

Upstream - significantly lower than estimate. Is the result consistent - that is near identical everytime? And what about on other speedtesters?

Which modem do you have ? ECI or Huawei? If a Huawei - is it unlocked so you can see the stats?


You mention 1 mile from the exchange - but what is the distance from the cabinet that feeds you?

The upstream result is very consistent, between 9-10Mbps since day 1, using different speed tests.

I am using the Draytek Vigor 2850vn both as modem and router (i.e. I have put away the white box that BT supplied, and HH3).

Not sure about the distance to actual cabinet.

Based on those figures:

DS Attainable rate: 46360 and Actual (sync) 46360 >>>> Suggests that your speedtests are reasonable for the 46Mbps sync. Yes they are under the estimate but estimates really are just an educated guess and if there is more noise or lighter gauge wires it is easy to come in slightly under.

US Attainable rate: 13701 and Actual (sync) 13935 with previous Actual of 15023 >>>> Suggests that the speedtest readings of 9.x Mbps are well under what you should be achieving. A 13.7 sync should give somewhere in the 12 to 12.5 Mbps region which is over 30% greater than you are seeing.

You need to confirm by doing tests at various times on TBB, sppedtest.net and Visualware.com and recording the EXACT values to 2 decimal places. then when you have a 20 sets of results start to compare all of those from the same test. Are they almost exactly the same? And if you could borrow a PC and run Task Manager to look at the UPstream graph - is it almost flat or is the a good amount of ripple. Generally; flat suggests a cap somewhere, but ripple indicates that it is the line characteristics.
