Could you be a bit more specific about the hang up? Do you get any error messages? Does the kernel hang completely (i.e., does it need hard reset / Ctrl-Alt-Del / something)? If you run in text console mode, do you get any kernel messages when the hang happens?

Depends on what kind of problems that is.. I need some more information to give more guesses about the reason. The driver uses 11 Mbps even though iwconfig reports 2 Mbps in Master mode (this has been changed in latest CVS version).
