So, having connected my Ford Focus stalk, I've decided to get ambitious. I thought that while I've got the dashboard in pieces this afternoon, I might fit my car with Ethernet. I've got a funky adapter thingummy that Mark made up (see attached) -- it slots into the back of the cage, and positions the Ethernet jack properly for docking.

My question: my laptop's not auto-sensing for cross-over/straight-through, so I'll need a hub or switch or something in the car. Something that hands out DHCP addresses would be good, too.

So: any recommendations? I'm thinking that installing a WAP so I can use my laptop would be cool, but I'd also like, in future to be able to bridge to the flat, provided I'm within range.

Moreover, how should I power the thing?

Sorry about the non-specific nature of the questions, but I've not thought too much about this yet.
