Cant Connect To Wifi Raspberry Pi 4B

xXALPHAWOLF420Xx

Imaged the os for raspberry pi 4. I've tried changing /etc/wpa_supplicant/wpa_supplicant.conf described here:

https://www.raspberrypi.org/forums/viewtopic.php?t=247982

Changed the resolution as well as trying to connect to a router with 5hz.

Checked for MAC blocking there wasnt any (can connect fine with raspbian no problems only fails on retropie)

Like seemingly everyone who has had this problem Im out of idea.

Why doesn't wifi just work like on raspbian? Why is this so stupidly hard?

@xXALPHAWOLF420Xx Did you set-up the Country for WLAN from raspi-config ?

@mitu As previously stated I followed the advice in the thread I posted. I have it set up basically the same way besides the ssid and the password. Not sure how to screen shot, doesn't really matter since I copied that thread anyway.

Same problem for me, impossible to connect to my network, tried both 2.4 and 5 ghz.

Can you post the output of the following commands ?

iw reg get 
sudo wpa_cli -p /var/run/wpa_supplicant.conf -i wlan0 status

You can try adding more log info to the WiFi service with

wpa_cli -p /var/run/wpa_supplicant.conf -i wlan0 log_level debug

and then re-configure the WiFi by running

sudo raspi-config

Look for any error messages in /var/log/daemon.log.

This is too complicated... connecting to wifi should be very simple.
Sorry but I give up for now, I am done trying to make retropie working for the last 2 hours, no wifi, black screen, it is not a friendly user system and too many problems...

@redfirebrooks Sorry, the reply was not addressed to you, but to the original poster.

@redfirebrooks ethernet cable works out of the box so thats a work around for now if the commands dont work, that way you can samba the roms over.

Cant seem to see any available wifi networks when I go to the settings page with the UI.

Let me know your thoughts.

@xxalphawolf420xx From the 2nd screenshot, I see that the WLAN Country hasn't been set. It shows as DFS-UNSET, while on a working system it should show:

root@pie4:/home/pi# iw reg get
global
country UK: DFS-ETSI
	(5250 - 5330 @ 80), (N/A, 20), (0 ms), DFS, AUTO-BW
	(5490 - 5710 @ 160), (N/A, 27), (0 ms), DFS
	(57000 - 66000 @ 2160), (N/A, 40), (N/A)

The other command screenshot looks like the command's been miss-typed (wlan instead of wlan0).
Check again your wpa_supplicant.conf and make sure it's correct - no extraneous characters, proper newlines, no funny quotes, un-balanced parantheses {/}. Post it here to take a look.
