can u completely not send any traffic or is this a random drop. If random there could be interference causing replay counter mismatch. This may force AP to drop the packet, the ap may de authenticate client if it sees continuous stream of such packets in a short interval and force client to drop existing sessions like ftp. Please try changing the channel. If the client and AP are both A capable please try using the A band as there are more non overlapping channels and u may be able to find a channel with low interference.
