I have several clients that conect up on 802.11n that are running at 7mbps. Cisco seems to think that it is because the clients are running a single spatial. Why would a client connect to N if it has only one antenna when it could be faster with just 802.11 a/b/g?
Its what the client and the AP negotiates as. Clients will always try to connect to 802.11n rather than a/g. Thats just how client devices seem to work. You can disable 802.11n, but if your client isn't negotiating properly or is negotiating at a lower data rate, you will still be running low.
