That one worked for me for a couple of days as well, before it crashed again and became unable to keep a stable connection even for five good minutes!
Since a couple weeks I am now running an Atheros AR5B195 Wifi+bluetooth combo card bought for $3 on E-bay from China.
100% smooth operation, zero drops, 30-50 megabit speeds most of the time. Just what Wifi-N is supposed to be in an environment without too many disturbance sources. So life is now good. I am going to return the Intel 2230 card to the store right now. Not much money, but certainly enough to buy a fine bottle of Cabernet to celebrate the fact that I have now gotten rid of the little absurdly problem-ridden silicon brick.
