So sometimes I am a moron.
But in my defence the cable has ‘Orange’ and ‘Browney Orange’ and ‘Sort of White’ and ‘Sort of off white’ as colour combinations. This is probably because it’s cheap-knock-off-not-at-all-convinced-it’s-twisted-twisted-pair-Cat-E cable.
At any rate, I plugged in my cable tester to said socket and determined that 1, 2, 7, & 8 were all mixed up. I’ve no idea why. I’m impressed that it functioned at all, albeit unreliably.
Anyhow, I carefully wrote down what the cable tester said, and carefully swapped the wiring around to match. And lo, plugged in the cable tester again… and err, 1, 2, 7 and 8 were all still wrong.
A bit more fiddling and I realised that 1, 2, 7 and 8 don’t actually correlate to 1, 2, 7 and 8 on the socket. Oh no. That would be easy. (As would the colours in the cable matching the colours in the socket. That would be *way* to easy).
Another carefully considered round of swapping and lo, 1, 2, 7 and 8 now work. Indeed, 1 through 8 now work.
Which means the squeezebox in the kitchen works.
Which means Valve-Radio goodness for BBC Radio 6 and the entirety of the music collection.
Hurrah!
