Yes tested and swapped out. Having got 1000/1000 and screwed it back on the wall, its dropped back to 100/100 so I'm pretty sure I just have to do better at the terminating and with luck the new euromods and new punchdown tool will help when they arrive.Have you replaced the patch leads at each end? (Or at least tested them with your tester?)
What?A final piece was two interconnects between socket and PC that gave only 100/100 and a third swap that gave 1000/1000.
