Ethernet download speed issue in the evenings, Edinburgh.

[Doddie]

I'm in Edinburgh and my Windows 10 PC is connected to the Ultrahub via ethernet cable (it doesn't have wireless capability), the FTTP cabling was laid by Cityfibre.
For around a week now i've had terrible download speeds on my PC from around 17:00 through to midnight, either side of those times there is no issue with regular sustained speeds of around 940Mbps down and 840Mbps up.

Right now i'm seeing again, speeds of between 7-15Mbps down and 840Mbps up.

The odd things is that wireless speeds don't seem to be effected as confirmed on 2 mobile phones and a Microsoft Surface Pro tablet, i don't understand how the Ultrahub is able to maintain it's wireless speed yet the LAN port is somehow slowing to a crawl.
e.g. if it is simply a network demand issue then surely it would effect a wireless connection as well?

All the speed tests above were using Ookla Speedtest.

Below are two tracert's, one to bbc.com, the other to bbc.co.uk

Both tracert's were taken within 15 minutes of each other at about 9pm tonight, any insight into what's happening and why, and if there's anything i can do at my end, would be greatly appreciated.

Quick tracert update now my download speeds are recovering, as they do at around this time of night, (currently i'm seeing 579Mbps down and 823 Mbps up on Speedtest).
The results this time were run concurrently so no 15 minute between them other than changing .com to .co.uk and running tracert.

I have no idea if these trace routes are helpful but given past experience i fully expect my upload speeds to be fully normal again in an hour or less so i'll run the the same tests again so you can maybe see what, if anything, is changing.

[Doddie]

As i said in my previous post, i fully expected my speeds to have returned to normal at this time and they have.
Consistently seeing 939Mbps down and 820Mbps up now.

Results of tracert to bbc.com and bbc.co.uk now show:

I just can't get my head around why it's only the LAN ports that have this issue, yes i've tried both ports and rebooted the Ultrahub many times, yet this keeps happening nightly in a period of between 17:00 and midnight, it's so odd.
Fwiw, when it happens it doesn't just suddenly happen, it's something that slowly gets worse over a period of about 30-60 minutes until the download speed hits rock bottom, that then about 23:00 slowly begins to recover, but it's only on the LAN ports this is happening.
Wireless remains strong for both upload and download, if it were faulty LAN ports i could understand that but it makes no sense that outwith the effected time period the LAN ports transfer data normally... there has to be some other reason that is above my pay grade and i have no idea what it it could be.

This is what I'm experiencing.

BQM

Speed

Latency

It's apparent from the packet loss some switching is going on. When I have high latency to the Manchester Gateway my speed to my London VPN increases during these periods and the packet loss spike at the end of the period would indicate some kind of switching. My Gateway IP remains the same throughout.

VPN

Make of it what you will. 5% download speed at peak time isn't funny, but I'm glad I don't stream or game in the evenings.

[Ripshod]

Additional. The speedtest server I use (Vodafone Manchester ) doesn't return any packet loss figures, so here's the same London VPN

THAT'S A LOT OF LOSS!

[Doddie]

@RipshodThanks for that additional info, i understand some of it but to be honest not that much of it.
Tonight is slightly better but still very poor, speedtest is showing 195Mbps down, 835Mbps up.

Hi @Doddie, I'm sorry to hear you are facing speed drops on our service. From the information you have provided, if the speed doesn't drop using wifi only using the ethernet cable, it's likely not an issue with the speed the router is getting but it may be the router itself. 

Please run our diagnostic tool here - https://vodafone.uk/2Wa6bEU, just to make sure you have no issues with the speeds provided to the router and if you see no issues with the speed or no issues are flagged on the tool, then please contact our dedicated Broadband support teams - 03333 040 191 from any other network/landline. Also, webchat here - https://vodafone.uk/2yfUgNH.

Hi @Tal Thanks for the reply, i ran the test just now and there were no issues but i didn't expect there to be at this time, it isn't until around 6pm that the speed drops off.
I'll run the test again at around 7pm when every night for the last week or so the download speeds have been at their worst.

[Tal]

Thank you for getting back to me @Doddie. Please do run the test later on this evening and if it shows no issues, then I would advice to get in touch with us so we can run a few checks on the service on our side and help get this resolved - 03333 040 191 from any other network/landline. Also, webchat here - https://vodafone.uk/2yfUgNH.

Thanks again @Tal, one quick question if you don't mind, is the Broadband support team available 24/7 or are they only available to call during certain hours?... I can't seem to find a definitive answer to that on the VF website.
I only ask because i will call them if there are no issues reported in the speed test you linked to above.
