Yep. I recently renewed my "experimental" station using new software on a new PI 3 and I got Wifi working almost immediately, no problems.
I edited the /etc/wpa_supplicant/wpa_supplicant.conf file for which you have to unlock the read/write and then edit the permanent one which is /etc_org/wpa_supplicant/wpa_supplicant.conf. So something like:
sudo /root/mount_rw.bash
sudo nano /etc_org/wpa_supplicant/wpa_supplicant.conf
Then add in lines with your SSID and password:
network={
ssid="<ssid>"
psk="<password>"
}
Then set read-only again:
sudo /root/mount_ro.bash
and reboot.
I've set up a static IP address as well on mine so I can easily find it and log on using SSH, but that's not necessary just for it to run.
I *think* this time around that's all I did and it connected to my Wifi. I'm not in Guildford at the moment so I don't know if this is exactly correct but if it doesn't work, come back and I'll check.
