It seems you don't quite understand what netctl-auto is. It uses wpa_actiond to automatically connect to ANY of the wireless profiles on an interface it's enabled on. For example:
$ sudo systemctl start firstname.lastname@example.org
If it's connected to the wrong network, then either use wifi-menu or the command you tried:
$ sudo netctl-auto switch-to correctNetwork
But if this is a computer that doesn't ever move, consider just
enableing the profile.
netctl-auto uses extra memory (albeit not too much) but it also adds extra complexity. If you run:
$ sudo netctl enable tq84-wifi
then it will attempt to connect to
tq84-wifi on boot and will not try anything else. You can also
$ sudo netctl start tq84-wifi
to attempt to connect immediately.
netctl-auto is for mobile computers such as laptops that should connect to and switch between any of multiple predefined networks automatically (this is what most OSes do by default). If the computer is not mobile, just
sudo netctl enable [profile] to have it connect on boot.
