Just running a cable through some walls, I know I should probably use solid core but want to keep it cheap, got a few cables to use and trying to decide which basically. 1) Ebay special, apparently is Cat 6E (yup, really), 26 AWG (I thought cat6 had to be 22awg), 20 metres 2) Old Microsoft xbox Cat 5E cross over cable, 24 AWG (decent build quality), 10 metres 3) Belkin Cat 5E crossover cable, 24AWG, 6 metres 4) No markings on cable at all (strange?), only thing is the word "Net-x" on the connector, relatively stiff so could this be solid core? Length 10-20 metres (coiled atm). It's going to be used to run between two gigabit switches (daisy chained from router so that all traffic is gigabit).
