I've tried three types of connection: Wireless 2G, Wireless 5G and Wired connection. So far, the fastest speed I got was on Wireless 2G connection (upload around 0.5 Mbps). The speed test history is below:

I'm using a late 27" 2015 iMac, so the network card is not an issue
However, There are quite a few T3 errors in your logs suggesting an upstream impairment such as noise on your local segment.
You will need to contact VM for resolution, either by waiting here about a week until a VM Forum Team Member picks up the thread, or give them a call on 150 from a VM line or 0345 454 1111 for a quicker response.
This problem (or area wide upgrade as the CS call it) has been going on for weeks now. It first started about 3-4 weeks ago with constant service disruption and for the last 2 weeks with upload speed being nowhere near to what they should be. Download speed is ok, getting 54mbits a sec but upload doesn't go above 0.35mbits/s.
I spoke to CS about this on the 7th Dec (not to mention 4-5 calls in the weeks leading up to this), and I was being assured that the upgrade will be complete by the 9th and upload speeds should return to normal. Its now 15th and still no improvement.
I attach speed report for the last few days and would love to know if this is at all going to get fixed. I am unable to upload things, have video calls, etc..anything that requires decent (reasonable) upload speed.
