Can I add WiFi config to SD card pre-install? (headless setup) azeam January 11, 2018 at 5:07 PM Yes, it's possible. Mount the SD card on your computer and create (as root): Code nano /where_sd_card_is_mounted/storage/.cache/connman/mywifi.config Add the following (change "mywifi" after "Name" to your SSID and "passphrase" to your passphrase), save the file and boot your pi: Code [service_wifi_mywifi] Type = wifi Name = mywifi Passphrase = passphrase
