BT Infinity Option 2 Upgrade - Fail, or impatience?


[link to this post]
 
So I had BT Infinity Option 2 installed in January which has been flippin' brilliant I must say.

Been getting full throughput morning noon and night, can't fault it. Even good with P2P with the right settings.

Upgraded to the 80/20 yesterday, which is great. Except that it isn't.

Whilst I am now getting 17Mbit upstream throughput my downstream throughput has halved frown

Weird thing is BT Speedtester reports an IP Profile of 77.43 Mbit/sec. So my sync rate must be around the full 80 meg mark to be given an IP profile of 77.43 surely?

Is this normal and can I expect it to settle during the magical 10 day stabilisation period or just BT reverting to their usual selves?

If anyone can share their experience of upgrading to 80/20 infinity I'd appreciate it smile

Thanks

Can you show the results of BT, TBB and speedtest.net tests?

Also, take a screenshot of TaskManager (Network Tab) to give a graphical representation host the image and post a link.

That will give an overall picture of what is happening.

Reboot both the modem and router. (It may not be necessary to do the modem, just might as well).

To add its only worth doing any of the testing when using ethernet, as even 802.11n is going to struggle with 80 Meg connections

Maybe give it a few days.
I had exactly the same thing when I switched from 40/10 to 80/20. Download speeds on everything (except multi-thread downloads & Usenet) were below 16Mbps.
It was so bad it appeared (and I'm still not sure it wasn't) BT were throttling each download thread.

It seemed to recover 4-5 days after the upgrade.
Now only the TBB speedtester gives rubbish speeds (but I've yet to be convinced that's not just broken).
Most speedtests (regardless of time of day) hit around 76/16.

Single http downloads are still a little on the slow side with speeds bouncing all over the place (the 1GB test file from TBB is all over the place (literally one second it's hitting 45Mbps, then 18Mbps a second later).
Either BT are still throttling single download threads or TBB not only have an issue with their speedtester, they also have an issue with their upload ability (of their test files).

Whatever it is, the speeds are a lot better than they were a week ago (when my shiny new 80Mbps download was lucky to hit 5Mbps).

Try a TBB test file using a download manager (so you get get more than one thread/segment going at a time) and see if your line is actually able to hit the maximum speed of around 76Mbps.
My guess is it will and you're just seeing the same as I (a limit/cap on each download thread, but the line still able to acheive maximum speed by setting multiple downloads/threads)...i.e. It's being throttled!

Update!

Ignore TBB downloads (test files or their speedtester). Both are most definitely broken (or their links to BT are not performing well).

The TBB 1GB test file averages around 32Mbps (single thread download), never gets more than around 45Mbps and spends most of its time below 30Mbps, and their speedtester is still giving little more than half the upload & download speeds as others.

Just tried a 1GB test file (source recommended by Croftie) and it's hitting max speed (around 76Mbps). Still bounces around all over the place (indicating some throttling or capacity issues at BT) but the download spends most of its time above 55Mbps and is averaging at least twice the speed available from the TBB test file.

If you're using TBB tests as a basis for noting your download speed is rubbish, check elsewhere because it really seems like the TBB test files and speedtester are not helping (by giving rubbish results themselves).

Many others are also reporting issues with the TBB tests.

My brother went through the same experience although his download was still about 39Mbps... it was his AV/Firewall software Kaspersky, it either couldn't process the data as fast as needed or was throttling it somehow.

He uninstalled it and used ESET instead and now gets the full download speed

Doing some tests a few months back I was able to get 80 -90 Mbps from the TBB tester on a consistent basis. I did not have full control of the circuit so there was other traffic but the tester was easily able to provide those speeds.

Indeed; it was OK, now it's not (and this also goes for the TBB test files).

Agreed. Last time I did a test, TBB's tester was reporting ~45 down and 6 up. A test transfer of a single file to/from my own dedicated server in France easily maxed out at 75mbps down at 19.5 up. Speedtest.net which is reasonable but not excellent for upload was reporting 74.5/17.5

Testing done!


[re: izools] [link to this post]
 
OK so just for good measure I've:

Rebooted the HH3 and Openreach modem (is a newer ECI modem, installed this year)
Disconnected all and sundry from the router, disabled the router WiFi
Connected to my laptop via Ethernet
Disabled AV / Firewall / Etc (use Comodo free internet security suite usually)
Disabled Wifi card on laptop
Ran CCleaner
IPConfig /release
IPConfig /renew
IPConfig /flushdns
Closed any tray apps

Unfortunately this hasn't made any difference:

So definately a BT issue. Hopefully it clears up during the stabilization period smile

Can you get a screen shot showing Task manager during the downloads? It should show the speeds being seen every 1/4 second or so. That will show whether the maximum of 70+ is being reached or something is throttling the traffic at a lower level.

I had task manager open throughout the tests but because the laptop was connecting to the router at 1GBps the paltry throughput I was getting was barely registering. I.e. a couple of pixels barely registering tongue

Yes. IP Profile is approximately 96.79% of sync. 77.43/0.9679 = 77998 79998.

Have you set the Task Manager Option to Auto Scale - ON ?

I too have a 1Gbps network but the scale is at 5% when downloading on a 40Mbps connection and the trace get to about 3/4 of the maximum.

OK, done one.

http://i.imgur.com/dtCTa.png

The first bit of traffic on the graph is the speedtest which seems to tie up accurately with the reported throughput. There is a brief flatline followed by the traffic generated by my copying a 700MB file from my local hard drive to the hard drive of another computer on the network.

I have done this to demonstrate that the wireless conneciton is not limiting throughput - I am able to obtain 11MByte/sec+ (Yes, MB) over my Wireless connection when copying to a wired client on the network.

I am using a 5.0GHz Netgear Wireless Access Point - the 2.4GHz band causes serious bandwidth issues with rates as high as we're dealing with here as you all know. Seems to work well, eh? smile

That suggests you are peaking at 120Mbps across the wireless ... so your local network is not slowing things down.

Have you checked that the MTU setting are correct? VDSL/Infinity requires 1492 or less.

Strange that it's showing you're only on 10mbps for your upstream profile. My line sync's at 16993 right now (banded profile [censored]) but upstream IP profile is listed at 20mbps.

Something's weird/stuck/not right
