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

HH5 Helpdesk:

6. Data rate: 20000 / 79995
7. Maximum data rate: 30850 / 108537
8. Noise margin: 12.9 / 13.8
9. Line attenuation: 0.0 / 6.1

HH5 Advanced Settings, Broadband, Connection:

Downstream: 78.12 Mbps
Upstream: 19.53 Mbps

BT Wholesale test:

Download speed 75.13Mbps
IP Profile 77.43Mbps

Upload speed 8.81Mbps
IP Profile 20Mbps

TBB Speedtest:

Avg Down 38.32Mbps
Avg Up 9.58Mbps

Speednet (a number of tests run to find the best result):

Down 38.57Mbit
Up 9.30Mbit

BBMax:

Down 38566kbps
Up 9382kbps

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)
