That screen shot is more useful. Does the Tx/Rx B/s update in real time (more or less)? If so, you can monitor the throughput on DSL and see if the connection is hitting saturation in either direction. Something like a stuck email or windows update can really easily do this on slow connections.

The frustration of people not actually believing it could Actually be the connection and not something hardware/software related makes me regret even posting on a forum already.

It could actually be the connection, but it could be a bunch of other things as well. It requires a methodical approach to troubleshooting, and given your ISP has started that and confirmed the problem is outside of their network, the next step is looking at your network as well as verifying the DSL. A screenshot of a speedtest isn't enough technical information to troubleshoot with.

By far the most common issue with increased latency of slower connections (as ADSL is) is saturation, and it doesn't take much at all to saturate 1Mb/s.

How are you actually measuring latency, and to where? Can you set up a ping to the next hop past your own router and see how that changes with traffic on your connection? What does your internal network consist of - what router and all other devices?

Vodafone have outright refused to log a fault, they won't Do anything short of basic script-reading level of help.

I'm going to run WinMTR to the aussie wow server listed on blizz's support page and see if anything comes up over the next hour or so. My internal network is literally the modemrouter and an ethernet cable to my PC right now. Nothing else, everything else is/has been disconnected for two weeks while i've been trying to solve this.

Try testing to a closer server first. Rule out your internal network first, otherwise you will have the variation of the rest of the internet to fudge your test results.

I don't use any email programs, and the built in windows 10 one has no accounts in it, and windows update doesn't seem to be doing anything - I even have the delivery optimisation turned off by habit.

I think that datalog thing will do realtime by not sure if i can access the log.

the chances of it being anything other than upstream contention is extremely low, that's why we all jump to that to troubleshoot first.

the second step is looking at things like CRC error rates, highly unlikely given your stats that there is anything wrong with your rates though.

This is a WinMTR result for the last little while to the wow server in aussie 103.4.115.248

is that testing over wireless or ethernet?

your average would indicate to me that it's definitely something utilization wise to be honest..

Ethernet, and my PC is the *only* thing plugged in - and it's locked down tighter than a nuns proverbial. There is nothing going in or out that I don't know about.

QoS on my router priorities WoW traffic over *everything* else.

I'm locking this as it is going nowhere. We've tried to provide advise and you keep disregarding it... You should listen to the advise given on here especially since the advise you've been given has come from industry professionals.

Figure out what is using your upstream bandwidth. Everything you've posted has pointed to that being the actual problem regardless of if you believe it or not. Also QoS can have a negative impact especially on gaming.

Also consider jumping ship to VDSL.
