Cannot connect pi 4 to wifi for headless set up

Hi! I am rather new to raspberry pi and I am very excited for it. However I am not able to connect it to the WIFI for a headless set up. I tried following the online forums and added the ssh file to the sd card as well as wpa_supplicant.conf which looks like this in mine:

Code: Select all

country=US
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
scan_ssid=1
ssid="***"
psk="***"
}
I have tried re-downloading and reformatting the sd card as suggested by user guide and still no luck. Once I try these and put sd into raspberry pi it appears to boot with lots of flashing of act green led and then when I look at my router there is no connection for raspberry pi so I do not know if it is connecting. There are some connections that are un-named but every forum I check has it popping up with a name. Maybe this was erased when I reformatted? Any help would be much appreciated and I would be happy to share any additional information!

For raspios the documentation is here: https://www.raspberrypi.org/documentati ... eadless.md

ssid_scan=1 should not be needed unless you're hiding your SSID, which is a useless nuisance.

If that doesn't work check your router/AP settings.
