Ok, I've moved my mac mini down a floor so it's directly above the access point. Full strength signal down here, and apart from failing to connect automatically I don't seem to have the same problems at all. There are still some fluctuations, but no odd disconnects and fits and starts. It seems a bit cr*p that the mini's reception is so poor compared to my ibook, but under the circumstances I don't think I should complain! I'll keep it down here for a while to get a longer sample/test period.
