I'd agree that I have probably had issues forever with my inet - they are certainly worse on this particular connection, but yes. as I said at the start I have kinda come to expect that I wont ever get a fast connection here. My ping in fps games has always been pretty stable though, but ms in my current game is intermittently great and horrendous. Streaming has only really become a serious problem the past few months.
I did a series of speed tests yesterday:

Not an awful lot of difference there - same went for the router, which gave exactly the same results apart from the Downstream Noise Margin, this was 6.3 that I posted her previously and it changed to 5.1 and 4.9 at 22.53 and 01.54 respectively. At some point between around 7pm and 10.30pm my ms shot up to around 300-400 and I had lag issues in game, the rest of the time it was comfortably between 27 and 51.
My set-up here is wired from this pc to the router. I do have a second pc with a wired and wireless connection, I game on both of them - but I don't use wireless at all, and I only use one pc at a time. There is no-one else using my line, not in the house, or outside. I have no neighbors for at least a mile, so someone would have to park a car outside to leach and ofc it is pw protected anyway.
The router, phone socket etc are all in the same room, very close to each other. I have previously changed all leads and the splitter (?) at the phone socket and had no change.
At some point I had problems when they first switched me over to this connection with my inet stuttering if I had a phone call, but they changed something and this is fine now. When I first switched to them from AOL, as I said previously, the switched interleaving off for me - I was playing fps at the time and ping was everything

However, when I check my profile now, it says Interleaving N/A - not sure if that means it is still off or it N/A on the LLU.
I do kinda hope that part of the problem is my set-up because I can control that, whereas at the moment is all seems at the mercy of whatever Daisy do or don't do. They are saying that there is a problem there - this is the latest from ADSL24:
It seems (despite work having allegedly been completed) the network providers are still acknowledging problems with latency at the exchange, My fear is that the whole thing with the upgrading the back end from the exchange (which is an expensive solution) was not the best solution here; that there was some other fault (possibly with a router) that was not detected & this is still manifesting and needs to be addressed. This, of course is just my hypothesising & may not be the problem at all, but they are acknowledging that there's a problem, so this should be addressed.
Hope that all helps somehow! Tried to include everything I could think of, but let me know if there's anything else I can tell you. Really appreciate the help here
