quick question, anyone know where to buy one from that is pretty easy to solder wires onto? Am I best to canibilise a wall socket?
Never used a solder version, but the push on style are easy enough to use. The wires are laid in a channel and then pressed in with a tool (can't remember the actual name). You can also find tool-less version that use a cap to press the wires.
Do you have all the right magnetics? If not, try and get a MagJack one, apparently they're pretty good. Alternatively just look here for a normal connector. Though if it's not PCB mounting and you don't need the magnetics, a wall socket might be cheapest.
I kinda doubt he's building his own network adapter. Unless you are, you don't want one with integrated transformers ("Magnetics").
