It was agreed we'd run a 24-hour line test with no devices connected. This ran from 4pm on 14th January to 4pm on 15th January. Some updated speed test results up to and just after this disconnection are below:-

I'm hoping to find out the results of the 24-hour line test tomorrow. In the meantime test results from speedtest.net are consistent with the problem upload speeds. This morning started optimistically with a decent upload but reverted to the norm:-

18/01/2021

8:40am - Ping 25, d/l 36.31, u/l 0.09 on wireless connection

8.45am - Ping 15, d/l 37.00, u/l 0.12 on wireless connection

10.32am - Ping 26, d/l 37.35, u/l 0.07 on wireless connection

2.43pm - Ping 26, d/l 35.23, u/l 0.05 on wireless connection

2.47pm Router restarted

2.48pm - Ping 26, d/l 35.40, u/ 0.06 on wireless connection

19/01/2021

8.35am - Ping 26, d/l 33.33, u/l 2.32 on wireless connection

9.40am - Ping 26, d/l 32.14, u/l 0.38 on wireless connection

2.20pm - Ping 25, d/l 35.34, u/l 0.55 on wireless connection

4.45pm - Ping 26, d/l 33.85, u/l 0.67 on wireless connection

So, the 24-hour line test proved no fault. The upload speed came back at around 2.7Mbps through this test. This is 1/3rd of what the line speed is at the router. I'm told there is nothing that can be done but that I can leave my contract penatly free. I'm told the issue is internal congestion caused by having 30 devices connected. These devices are:-

6 Amazon Alexa devices

5 Smart plugs

3 Laptops, only ever 2 used at any one time and not at the same time as phones or tablets

3 Sky Q boxes, not used at the same time as the other devices save for maybe one mobile phone or tablet

3 Smart TVs that aren't used at the same time, or with other devices and are mainly disconnected from the network

2 Mobile phones, not used at the same time as the laptops or tablets

2 Tablet devices, not used at the same time as phones or laptops

2 Printers - 1 3d and one normal

1 Smart lighting hub control

1 Smart heating control hub

1 CCTV system that doesn't upload to the web but does have remote viewing access

1 Ring doorbell with constant monitoring disabled

With the exception of the laptops, most of these devices have uploaded in a 10 day period between 0.9 and 68mb of data.

Does this really constitute an unreasonable level of use that can't be maintained by a modern router? If this was the cause of the problem then surely disconnecting all devices bar one would provide an improvement to the service being provided (which doesn't happen)?
