I had the same problem with the DWA-547 that I bought yesterday. The system freezes deterministically everytime when I enter the WPA2 password in nm-applet. The next time booting, nm-applet had the password saved and tries to connect right away, hence it freezes before the Desktop is fully up. It is a 64bit Linux installation of Ubuntu 9.10, updated yesterday. I just booted from a 32bit Ubuntu 9.10 CD; then it works and doesn't freeze. So I assume it's a problem with the ath9k driver specifically in the 64bit kernel. Now I'll replace my 64bit installation with the 32bit one, as I have no reason to run 64bit Linux anyway. If yours is a 64bit kernel: could you try the same (boot from 32bit CD) to see if things get better?
