I suppose it's possible you might not, but I don't recall seeing any user interface allowing you to do this on any commercial gear. > Also, one might want to set the psk before the nwid (for any reason).

Just a bit of head-scratching when you try and connect to an open network after having used a WPA network for a while and forgotten to do -wpapsk. Usually one works out the mistake within a minute or two though (at least in my experience :)
