Wireless TCP aborts

Using ssh and rsync to copy a lot of stuff from my
old desktop to my new laptop.  The old desktop is using
a wired connection to an (admittedly crappy) D-Link router,
the new one is using an Atheros wireless connection to the
same router.  I periodically see the transfer fail with
the following messages on the wireless side:

   Corrupted MAC on input.
   Disconnecting: Packet corrupt
   rsync: connection unexpectedly closed ... [receiver]

and then the rsync session is dead.

It seems odd that a single corrupt packet would terminate
the TCP connection.
