My experience of the GUI setup programs was not working so I used the FreeBSD manual page for my wifi setup.
(This is not a criticism, this is to help fellow users get up & running; it should also work for you.)

As the root operator alter these files
(My ethernet is re0, my wifi is rum0; change for your needs.)
Under the wifi part of /etc/rc.conf
ifconfig_wlan0="wpa dhcp ssid hubname"
Comment out or delete this section
# Auto-Enabled NICs from pc-sysinstall
Then as the root operator run
service netif start
& you should, hopefully, be able to browse the internet.
