Annoying Wireless - Suggestions?



My new laptop has a Realtek 8172 wireless card in it.  It seems to
work fine out-of-the-box with 802.11g and I am able to make it
intermittently connect to my 802.11n network.  It likes to drop off
the network and then fail to reconnect with a "bad password" error.
The access point is an Apple Airport Extreme (yea, yea, I know) and
the lspci information for this card is:

I'm running Ubuntu 10.04 AMD64.  I'm not opposed to ndiswrapper or
whatever to make it work, I just haven't had any luck so far.

Any ideas would be GREATLY appreciated!
