Ok, Firstly, I'm gonna apolgize for the length of this, but i'll be damned if i'm gonna miss something out.
As you can see, my connection speed is pants. Always has been. Hopefully we can fix this together.
I am also a member of the tweakxp forum, as well as a few others, and have tried a few things to no avail, so all got set back to the original settings awaiting (expert) advice from here. (p.s. I have tried VB's updated cablenut settings and no joy)
I have basically read through all this forum follwing all the tips, and losing more and more hair, until i figured that i really don't have a clue what else to do, so I just followed the instruction given by VanBuren (as you can see below).
