I added 'iface wlan0 inet dhcp' while there was a static ip configuration
in place.

With the dhcp line before the static configuration or with the dhcp line
in a separate file under interfaces.d, boot hangs for a short time while
it's trying dhcp, then boot completes, and it's connected with the static
ip number. I assume it hangs while trying to connect without the wpa
passphrase.

With the dhcp line at the end of /etc/network/interfaces, there's no delay
at boot, and it connects using the static ip number.

In all cases, if I run netman, it shows that I'm connected, it can
disconnect, and if I reconnect, I get an ip address in the dhcp range.

I didn't test it with wireless encryption turned off.
