If you ever want to set up a Raspberry Pi with wireless, without having to connect to it first, theres three steps you should perform.
Firstly, use Balena Etcher or another imaging program to copy the Pi image you intend to use (i've tried this with several, including the LiveATC image, and it works fine) onto the SD card. Once the imaging is done, you should see a 'Boot' drive in your computers, drive list.
Next, create a file called wpa_supplicant.conf on the boot drive in notepad and put the following into the file. This file configures the WiFi access for the Pi.
country=au
update_config=1
ctrl_interface=/var/run/wpa_supplicant
network={
scan_ssid=1
ssid="YourWIFISSID"
psk="YourWIFIPassword"
}
Change the country code to your country code. au = Australia, us=USA, gb=United Kingdom, fr=France, de=Germany, se=Sweden etc.
Update the SSID to your Wifi SSID and change the PSK to your Wifi Password (Pre Shared Key).
Finally, create a file called "ssh" (without an extension) on the boot drive.
Remove your SD card and reinsert it into your Pi. When it boots up, this will automatically configure your Wifi Settings, and the SSH file will tell the Pi to enable SSH access.
Voila. No need to connect Keyboard/Monitor etc to your Pi to get it going.
