All,
[.. big snippage..]
Just a quick follow-up to say that your comments haven't been ignored, I just wanted to test them before replying but haven't had the opportunity. Sorry I didn't reply sooner to say so.
I have some new RJ45 plugs (Kenable ones, arrived in the post this morning - I don't think a couple of pounds for 10 is particularly expensive for small quantities Brett, did you miss that there were 10 in the pack?) Hopefully this weekend I'll get to try a few things out.
PS: My main router is now a TP-Link OpenWRT router, I can't recall off the top of my head which model though.
