Having managed to fish the CAT6 cable fro the loft (second floor?) to the g/f office space, I need a 3m length to connect form the wall socket to the router (when Openreach finally manage to install the fibre; at the moment, this year, next year sometime, never!!)

The cable is a factory made, 50m with male at each end. I wonder about cutting a 3m length off, and fitting a male plug to each cut end, then I will have the necessary extension. But.... how do I know which wiring standard the factory fitted plugs? Either T568A or T568B? Is there a way to determine? Or is it just a case of wire one way and if it does not work, try the other?

Although I hardly need an RJ45 network tester, by chance, my favorite Lidl has them on sale today so bought one for the mega sum of £4.99.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18477&Focus=311387#Comment_311387 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18477&Focus=311387#Comment_311387 Tue, 08 Sep 2026 11:43:14 +0100 WillInAberdeen
But, £5 should buy you a factory-made 3m extension cable with no need to fit plugs yourself, or buy the necessary crimping tool, or learn how to do it.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18477&Focus=311391#Comment_311391 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18477&Focus=311391#Comment_311391 Tue, 08 Sep 2026 12:05:07 +0100 Rex https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18477&Focus=311392#Comment_311392 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18477&Focus=311392#Comment_311392 Tue, 08 Sep 2026 12:21:46 +0100 WillInAberdeen
If you want it to emerge neatly from the plasterboard, you can have it come out from a flex outlet plate

RJ11 is for phone extensions, 4 cores all twisted round each other. Better chance of connecting this one by hand successfully!

Iirc!]]>
