Over the past few days I've noticed that the speed of my fibre connection isn't what it used to be. I noticed that apps on my mobile such as Facebook have started to take a lot longer to load content; sometimes content loads instantly and at other times there can be a bit of a wait. I've run a few speed tests over an Ethernet connection and my download and upload speeds have dropped to about 50Mb and 6Mb, respectively, and haven't really gone back to 'normal' since where they used to be about 63.5Mb for download and 12Mb for upload. Would be grateful for any support you can provided.

Hi @champ388,
I'm sorry to hear that your speed has dropped. I've tested your line and the test indicates that the line is currently syncing at 59.5mbps down, which is within the estimates of 42.7-61.9mbps. However, the upload speed is 6.3mbps, which is below the estimates of 10.5 - 16.3mbps.

The test hasn't picked up the cause of the low upload speed, so we'll need to do some troubleshooting to try and narrow this down.
I'd recommend starting with basic checks here. If these checks don't resolve the problem, the next step would be to connect your router directly to the test socket, which is under the faceplate of your master socket and seeing if the connection stabilises This rules out internal wiring, face plates and extension sockets as being the cause. Please see the guide here for instructions on how to connect to the test socket.

Thanks for getting in touch. I've tried the basic checks and connecting the router (BT Smart Hub) directly to the test socket but unfortunately this didn't provide any improvement. I also tried connecting the Plusnet router (provided when I joined) directly to the test socket but that didn't provide any improvement, either.
As my upload speed has dropped below the estimate, surely this coincides with the drop in download speed?
Out of curiosity, is my issue the same as the one reported on this thread? https://community.plus.net/t5/Fibre-Broadband/Large-drop-in-speed-on-80-20-Fibre-in-past-week-or-so/...

Just running speed tests won't show immediate improvements due to the BTW/PN profiles. However if you log into the router and take note of the sync speeds and max attainable speeds that will give you a better idea if it's an internal wiring issue. But even before that, how is your phone line, dial 17070 option 2 - from a corded phone - does it give your number - is the line quiet?
I wasn't aware but thanks for pointing that out. I've tried connecting to the test socket again and took a note of the stats you suggested looking for, and a few more just in case they help:
- Data rate: 6.75 Mbps / 63.70 Mbps
- Maximum data rate: 6751 / 65571
- Noise margin: 6.1 dB / 3.2 dB
- Line attenuation: 19.5 dB

How do they compare when you are in the normal position?
Comparing them to the GEA test there is a definite improvement.

Stats with router plugged into normal socket:
- Data rate: 6.45 Mbps / 63.96 Mbps
- Maximum data rate: 6460 / 66390
- Noise margin: 6.2 dB / 3.3 dB
- Line attenuation: 19.5 dB
No changes have been made to the internal wiring and I've not had any issues with speed drops until recently.

Thanks for getting back to us.

It's possible though our tests aren't showing the cause for that, so we'd need to book an engineer visit for further investigation. I'd recommend raising a fault to us at http://faults.plus.net so we can arrange this. Feel free to let us know over here once you've reported the fault and we'll be happy to pick it up as soon as we can from over here.

Data rate: 12.99 Mbps / 70.83 Mbps
Maximum data rate: 13008 / 71790
Noise margin: 6 dB / 2.9 dB
Line attenuation: 19.4 dB
Happy to raise a fault if you think it's still necessary but also happy to monitor things over the next few days.

Hi @champ388
Thanks for the update.
Completely up to you regarding engineer VS monitor.
What do you want to do?
Thanks,
MoR

Hi folks. I've monitored things over the past few days and my download speeds haven't returned to normal. Any chance this issue could be looked into?

Sorry to hear this @champ388,
I've ran a GEA test on your circuit and can see that your DL is currently sat at 66.2Mbps.
Can you let us know what you are getting throughput wise on a wired connection?
Thanks,
MoR
