SWMBO's PC is up & running, not sorted the e mail out yet, but never mind.
Bought a 5 metre Cat 6 cable with male/male ends to connect the new PC to the router. Not piggin long enough! Went to Staples yesterday & they don't do a cable with male/female ends so I can extend it, nor do they do a 'joiner'.
Their only suggestion was to buy a new 10m cable.
I'm sure Maplins or someone online sells these things, prolly much cheaper than Staples, but being a numpty I don't know what to ask for - visions of "fork handles" .
Could some kind person point me at what to order please?
