Just a reminder: don't forget the A1200's PCMCIA-slot has a reseterror... Nothing big if you know how to handle a soldering iron (I don't) to solve it, but it can be annoying. It is always temporarily solve by re-inserting your networkcard when the A1200 is switched on.
BTW: my networkcard came with an adapter for one of the A1200's chips which solved the reseterror. Open up your A1200, look for the chip, click the adapter in place and that's it.
