Hey,I know that one. It slows down because it has to resend the damaged packets. There is a lot of data checking going on in a network connection, especially over the air. When a checksum fails the packet is requested again (nak - negative acknowledgment). If a received-packet-acknowledgment fails, the sender times out and starts again with the one that wasn't ack'ed. It can take up to about 5 times as long in interference situations, but the data arrives intact or not at all (but you'll know it). I have a Airport 1 about 50 feet from my Mac, and I have these problems when it rains.
