Experiencing slow upload speeds

Go to solution

Hi BT Team,

I'm on BT Super Fast Fibre Unlimited, I get around 50Mb download but my Upload has dropped from around 8Mb to now 1.6Mb. I've tried several restarts of the Hub etc to no avail. It seemed to have triggered on the 29th of March as the upload speed halved to 4Mb and then 1.6Mb on the 3rd April. Can anyone please help?

Relevant info from the Home hub after a fresh restart:

Product Name:  HomeHub5

  1. Serial number: +076286+1529001440
  2. Firmware version: v0.07.08.11237-BT (Type B) Last updated 12/4/2019
  3. Board version: 01
  4. VDSL uptime: 0 days, 00:54:41
  5. Data Rate: 1605 / 49342
  6. Maximum Data Rate: 1605 / 49188
  7. Noise Margin: 6.4 / 3.3
  8. Line Attenuation: 26.3 / 23.6
  9. Signal Attenuation: 0.0 / 0.0

Welcome to this user forum. @moose82 

Is there any noise on your phone calls? Dial 17070 and select option 2, there should be no noise between the announcements.

Its possible that the cabinet port configuration has changed, as the total VDSL bandwidth is shared between download and upload.

Its a good idea to check at the test socket anyway, if you have not already done it.

Hi Keith,

Ok I will have to try that later as the connection is "in use" at the moment and I won't get a chance to tinker until later.

I'll report back with the output from the test socket as soon as possible.

Thanks for the advice so far!

I suspect that if its the same, then the only solution is going to be a visit from Openreach, and a reset of the port.

This does seem to be reported quite a few times on this forum, where the port settings get stuck and allocate the incorrect bandwidth to the upload path.

I finally managed to test the connection via the TEST port under the BT plate.

Interesting finding... I'm getting exceptionally fast download 62Mbps (faster than contract?) and upload is back at 8.5Mbps?

As soon as I put the plate back on the front and plug it into that again the connection drops right back down to 40Mbps/2Mbps.

Does that indicate a fault with the socket or internal wiring or something else? As I understand it, when you pull that front plate out it disconnects the rest of the house from the line so I guess it indicates a fault internally somewhere?

Any idea how I can request an engineer attend? I don't care if it costs money, I need connection for work so can charge back to the company if need be... backing up to Cloud and uploading documents is dire!

@moose82 

Its most likely an internal wiring issue.

What does your master phone socket look like?

Master socket with one socket

Or

Master socket with two sockets

Hey Keith,

Single socket Openreach label (top row, second in from left)

My next test is to start disconnecting extension wiring from that plate and see if I can find what is causing the problem.

Then check the extension sockets around the house for some kind of issue... A lot of homework for me I guess! Thankfully I do have a punchdown tool to tinker with the internal wires.

So its the one with the clip on front cover, is that correct?

As far as as extensions are concerned, unless you actually need them, they are best disconnected at that master socket, as you are unlikely to fix the issue without a filtered faceplate.

If it is the clip on one, then you can simply replace the front part with the MK4 filtered faceplate.
