Today I bought a new PCI wireless card, TP-Link WN851ND, with Atheros AR9227 chipset.

It has 2 antennas and is compatible with Wifi N so I thought it would improve the quality of the signal. But after install it on my computer the result is the opposite to expected. It doesn't connect to my network, while my old Wifi BG card connect without problems, I created an access point from my smartphone to try the card, and work, but is very slow loading pages. In Windows 7 works perfectly, so I think the problem is the driver.

I have Ubuntu 12.04 LTS with kernel 3.2.0.31, is there a way to update the driver or I can apply a patch to improve the performance of the card?

Otherwise, anyone know if there is a work in progress to improve compatibility with this chipset, or is it better to change the card and buy one with better driver compatibility.

And finally, which wireless N compatible chipsets have good support under Linux/Ubuntu?

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version.
