The RetroPie Configuration Page. The WiFi option is the one at the bottom
You will need to first set your country in the Raspberry Pi Configuration tool.
The Raspberry Pi Software Configuration Tool. Set your WiFi country in Localisation Options.
Go down to
Option 4, which is called
Localisation Options. Tip: It’s easier using the keyboard on this config menu than the controller.
Then on the next page, again choose
Option 4, which is
Change Wi-fi Country. (If you’re in the UK, then it’s in the G section between Gabon and Grenada.)
If you’re ever likely to interact with your Pi using SSH, then we may as well do that now. Go down to
Option 5: Interfacing Options, then enable
Option 2 to enable SSH. (If none of that made sense to you, it is unlikely you will want to use SSH, so skip this bit – you can always come back later)
Now go down to
Finish, and you’ll be thrown to the following page.
Option 1 to add your WiFi credentials. Once connected, the screen will display your IP address – make a note of it, or snap a picture of the screen with your phone. (This is handy if you’re going to be using SSH)
If you need to find your IP address at a later stage, you can always view it in the RetroPie setting page within EmulationStation.
Now go to
Exit, and you’ll get back to the main RetroPie Interface.
