In order to acivate wireless in Rasp Pi 400 I have used the following terminal commands
Start raspi-config with: sudo raspi-config.
Go into System Options > Wireless LAN.
Type SSID and password.
Having done that the system is now asking me for a pre-shared key.
Where do I find that key?
Thanks

Hi @Brenton472
Using SSH with pre-shared keys requires a setup process before you attempt to use a secure SSH connection.
It requires you to setup a pair of key files - one public, and one private - and then copying the public key to the remote host. As you then try to initiate the connection, the remote and local machines authenticate each other by analysing the key values exchanged during the connection cycle.
This is a link to a detailed article from the FreeBSD forums about doing this setup - it also has links to further explanations.
And this is a link specific to setting up SSH keys on Raspberry PI’s
Using shared keys has two benefits
- security - as the remote is authenticated, stops the average Joe acessing your PI
- quick login - as you no longer need to remember and use a password.
And drawbacks
- you need to know how to / remember how to setup the keys
- you need to be able to safely transport and install the public key on the remote

Hi Brenton,
With everything enabled you should be able to connect by clicking the globe icon in the top right of the taskbar.
Are you using the default Raspberry Pi OS? Once you setup your localisation, WiFi should be enabled by default (unless you might have disabled it somewhere).
I’d try a fresh install of Pi OS and checking out these tips: https://support.thepihut.com/hc/en-us/articles/360014695877-Raspberry-Pi-won-t-connect-to-WiFi
