() One thing to keep in mind is that since I started using geli+ZFS (installed with PC-BSD 9.1 cd), I always got "Cannot reset interface wlan0 - exit status 1" with "wifimgr" whichever action i did (ex: reconect, rescan, up/down,etc). I would appreciate some help in debugging this. -- Best regards, Claudiu Vasadi
