BT Wholesale Broadband Performance Test

Following on from the HH5 messing up my line thread i have noticed there is still something wrong.

Using the BT Wholesale Broadband Performance Test site i get 75Mbit without question, every time no problems at all, using every other speedtest site on the planet (including the TBB one) i get 38Mbit. My upload is 10Mbit no matter where i test. I also tried downloading some big files and never got over 38Mbit so whats going on?

Stats are:

6. Data rate: 20000 / 79995
7. Maximum data rate: 30784 / 108023

Downstream: 78.12 Mbps
Upstream: 19.53 Mbps

Somewhere in BT's system it thinks you are on a 40/10 product, and the BT Wholesale download is somehow bypassing that part of the system. The other speed testers can't do that bypass so hit the cap.

What are the last two lines about in your post?

Which Infinity product are you on? Check in "My BT" on bt.com

The cheaper product limits your speeds, but the link from your HH to the cabinet is always at the best it can do, the speed limit is later in the network.

Since when did 40/10s sync at 80/20 on a short line?

It's the IP profile we need to see, clearly syncing at 80/20 on a really short line.

Upstream IP Profile is always the product figure,i.e 2000kbps, 10Mbps, 20Mbps. Mine:_

Upload speed achieved during the test was - 12.57Mbps
Additional Information:
Upstream Rate IP profile on your line is - 20 Mbps

Stats:-
Max: Upstream rate = 14603 Kbps, Downstream rate = 58844 Kbps
Bearer: 0, Upstream rate = 14391 Kbps, Downstream rate = 59418 Kbps

It is the IP profile for my connection.

Infinity 2 hence the problem, i ran at 75/18 for 2 years till i bought the sodding HH5

The IP profile is clear enough to see in the original post.

Downstream: 78.12 Mbps
Upstream: 19.53 Mbps

If that is coming from the HH5 it is very odd.

If it is coming from the Further diagnostics of the BTW Broadband Performance Test, that would be the first ever such reported.

For the two to be different would, to say the least, be interesting.

I suggest that the test would give 77.43Mbps/20Mbps. Unless it gives approximately 40/10 which would explain your problem.

As we have not seen upstream "real" IP Profiles before, I can only work from the downstream 79995kbps. The calculation for that on FTTC is 0.9679 x sync, equalling 77.43Mbps. The downstream one you have given is approximately 0.9769 x sync. Note the central two digits are transposed.

Your upstream figure is exactly 0.9769 x sync.

If you feel like it, please run that test . Don't bother with all the red instructions, we aren't bothered about the speed.

I had the 10Mbps upstream issue for a while ... had three or four long visits from BT Techs who worked with 2nd and 3rd line support. Something finally gave and it went from 9.xx to 19.xx instantaneously. I now get around 18.xx to 19.00 on speedtests except on the TBB one which seems to take time to ramp up.

No one at BT can actually explain what the problem was or what cured it and there are a few cases around that have suffered it.

Right lets clear this up LOL

Is this using an ethernet cable between the Homehub 5 and the PC?

Pretty clear, you're syncd at the max (80/20) but you're only getting 40/10 throughput.
As you're paying for Infinity 2 and its worked before, this is a fault.
For some reason you're on the wrong BTretail product/profile.

Not quite

BT Wholesale test:

Download speed 75.13Mbps
IP Profile 77.43Mbps

Upload speed 8.81Mbps
IP Profile 20Mbps

That's 80/20 throughput

OK. The difference in the IP Profiles is clear. Well done BT, LOL. My feeling is whoever twiddled the HH5 firmware has got something wrong, but that's not really the issue now we know there isn't either a 40 or a 10 floating around in there.

I'm tending again to my thoughts about there being a 40/10 setting somewhere, with the BTW speed test bypassing that on download but not on upload. That possibility doesn't seem at all odd to me.

My "other place" idea about the IP Profile stems from something not many will know about, and I only know a little. That being that (on ADSLx) when Plusnet's copy of the IP Profile gets out of step with the BTW speed test value, (PN lower than BTW), correcting the Plusnet version doesn't always fix the problem.

Plusnet often then run another test which they say "shows an imbalance" in the system. The only two places I can think of holding the BTW value are the BRAS and the DSLAM/MSAN, with the BTW speed test reporting only one of those. Plusnet are then able to sort things out.

This cannot, on the face of it, occur on FTTC as BTW don't control the DSLAM. Maybe I just destroyed my case . Maybe not. I never did get Plusnet to say where this third copy of the IP Profile is held.

We do know that we sometimes get weird low speeds on FTTC, even though the sync and IP Profile looks OK, and only after engineer intervention and getting something reset does it clear.

It would be of interest to see the TBB speedtest graph.

Yes - that's a good idea.

@Alnath - please could you run the tbb speed test and post the link to the graph result?

Results are identical using, Ethernet, Homeplug or WiFi (5Ghz n or ac)

Yes on the BTW test page only, everything else be it a speedtest site or a large download shows 38Mbit

Definitely a hard 40/10Mbps cap somewhere.

Yes, looks like a stuck BRAS profile

Hmmmm the moral of this story is get the lip out and reboot the HH5 3 or 4 times http://www.thinkbroadband.com/speedtest/results.html...

Hang on, give it 10 minutes and its back to what it was, seems to me its the HH5 thats at fault

I've put a spare router on and all seems well, anyone any ideas on how i get the HH5 that i paid for replaced or refunded?

Yes, that's because the wholesale test bypasses the ISP side profile doesn't it? I thought we'd seen that when PlusNet's profile was wrong, the wholesale test showed the capability of the sync, not the throughput to the ISP.

No. If the Plusnet copy IP Profile is low, it affects the BTW speedtest result.

Ok that makes sense.

I think more data has arrived now showing a faulty HomeHub 5. (strange fault !).

Have you done a Factory reset?

You bought it from BT for £45 from here? It should be under a warranty and you have plenty of evidence to back it up.

In reply to a post by RobertoS:

yeah made no difference.

BT have swapped me out a HH5 and this one seems a bit better, the only speed test giving constant results is the BT one all the others are giving results up and down like a yoyo, i have given up TBH ill just wait until a firmware comes out and if there is no improvement im flogging the HH5 and buying HH4 as that was rock solid.

I give up this "new" HH5 has done a couple of random reboots and my speed is a rock solid 40/10 again on everything other than the BT speed test which returns 75/9

I have downloaded a couple of Linux distros just to see and the speeds never exceeded 40Mbit.

BT were massively helpful by saying the speed is fine, its your PC. By that reasoning it is also 4 laptops, 4 smartphones (2 of which are wireless ac) and 4 android tablets that are all bolloxed, cheers BT.

I guess its time to buy your own router - assuming you have and can put up with the separate VDSL modem.

Well despite the HH5 firmware updating and me praying it would fix everything something is still wrong.

BT:

Download speed achieved during the test was - 75.03 Mbps
IP Profile for your line is - 77.43 Mbps

Upload speed achieved during the test was - 12.25Mbps
Upstream Rate IP profile on your line is - 20 Mbps

I downloaded a 1.4GB file from Amazon and the download never exceeded 4.8MB
I downloaded the lastest PS3 firmware from Sony and the download never exceeded 4.8Mbit.

Wired or wireless it makes no difference.

I have put my HH3 and OR modem on and i am getting identical results so its not the equipment its something they have done when they switched me to infinity 1 and back to infinity 2

Well i have spent 6 hours chatting with the OR engineer regarding my problem.

My what a problem we seem to have!

Still no change and despite the engineers findings BT Retail seem to think the entire internet is wrong and their speedtest is right.

Hallelujah
