Windows – How to connect to wireless network via WPS with hidden SSID in Windows

You should be able to connect to a wireless network manually if you know the SSID and key. There's some option in the left pane of the "Wireless Network Connection" window that does this.

Here you go: How to manually connect to Wireless network not broadcasting SSID

Looks like you found it, but the lecture is still needed here because this is dangerous.

Hidden SSIDs are actually WORSE than security through obscurity. Not only is there the obvious problem, that someone with wireless sniffing software will still get the SSID, there's also the not so obvious problem - in turning off the SSID broadcast on the router, the client has to do a form of SSID broadcast instead, and this happens no matter where the computer is being used - any time the computer isn't connected to a more preferred network, it will be broadcasting looking for the hidden SSID.

This gives an attacker a tool that they can leverage to trick your computer into connecting to a hostile network. Now not only is your wireless network not safe at home, your computer isn't safe anywhere either.

Use the strongest possible encryption (sorry, WEP doesn't count anymore), and don't make the problem worse by shifting the SSID broadcast from the AP to the client.
