I thought I'd offer a follow-up to spartrekus' hint to enable wireless on the Pi3:

There are examples in /usr/share/doc/wpasupplicant/examples .  I copied wpa-psk-tkip.conf to /etc/network/homewifi.txt and edited for SSID and passphrase.
So my /etc/network/interfaces includes:

auto wlan0
iface wlan0 inet dhcp
wpa-conf /etc/network/homewifi.txt

Although ifconfig would show wlan0, I couldn't get wicd-curses to recognize the interface.  The edit to /etc/network/interfaces was the only way I could get wireless to work.  I even tried disabling networking and replacing with the wicd daemon to no avail.  But this method gives me wireless.
