You're absolutely right @dub_nerd , must have been having a "senior moment"<snip> DO NOT BUY THE CABLE that SparkRite linked above (sorry SparkRite). That's a phone/modem cable with RJ11 connectors. You need an Ethernet cable, with RJ45 connectors. <snip>
However in my defence I was on the Screwfix site at the time and just did a search for "Ethernet cable", this was the first that popped up and looked in the spec. and this is what it said:-
- Brand : Philex
- Cable Code : 76702HS
- Product Length : 3000 mm
- Cable Product Type : Ethernet
- Cable Length : 3 m
Well spotted !
