@TrisM Though it is an old thread and I haven't asked/wondered aloud back over nearly 2 years ago, was considering it to be just a SEP. But as you revoked revived the thread I am doing it now, because now I am really puzzled/curious and doubting again: I have Windows 10 Pro on 2 desktop + 1 laptop machines since the EOL of Window 7 and a third desktop setup in 2020. None of them had this behaviour and on all four (3 on 22H2, my laptop still on 21H2) this Group Policy is still defaulting to "Not configured" [edit: besides Mitus remark in the early posts that it is disabled as default on some mints of win10 and that's not including home/pro] . And as Win10 is using "Language Packs" (as it was on xp x64) instead of regional versions of the os itself, I somehow doubt that updates are meddling with those settings differently for different regions and I am still unsure why this was changed on some user systems and whether it truly was done by the M$ Update or by other means and if yes under what circumstances this would have happened.

I didn't it, because i won't dissamble the GPi to connect the keyboard. So i have restored the SD-Card from Backup-File to save time. Now the WiFi works fine. It's a pity that I still don't know what the cause is. I've opened the wpa_supplicant.conf file to see any difference.

country=DE^M ctrl_interface=DIR=/var/run/wpa_supplicantGROUP=netdev^M update_config=1^M network={^M ssid="NETWORK"^M psk="PASSWORD"^M key_mgmt=WPA-PSK^M priority=1^M # RETROPIE CONFIG START network={ ssid="NETWORK" psk="PASSWORD" } # RETROPIE CONFIG END

It seems the same. But, it works. There must be another error.

I remember a topic a month ago with a similar problem - the pairing of Xbox controllers worked, but they acted as a single controller. The solution was to install an alternate driver for the controller - xpadneo (https://github.com/atar-axis/xpadneo).
If you want to give it a try, the installation is quite easy:

Remove any Bluetooth controller from the RetroPie script Bluetooth configuration. Remove the xpad driver from the RetroPie setup script, from the drivers package section. Install xpadneo (run this from the SSH session): git clone https://github.com/atar-axis/xpadneo.git cd xpadneo sudo ./install Reboot and then redo the Bluetooth pairing for the controllers.

See if you get 3 devices (/dev/input/event[0-2]) and Emulationstation detects all your controllers after the installation.

Use ssh and filezilla, you'll do 99% of what you need with these tools...
Configure wifi on the pi, activate ssh and that's all you need.

@WDW plug in a working controller and press start then exit emulationstation(takes you to command line).
type: sudo /home/pi/RetroPie-Setup/retropie_setup.sh (setup menu)
then go to config, then find bluetooth. (while youre here check 8bitdo hack is off). Next forget devices and reconnect one gamepad.
If it stays connected then:
run: jstest /dev/input/js0 (checks input of first controller device- press buttons)
If the previous works then you might have a problem with emulationstation or something thus i dont know how to fix.

If not then try the following:

sudo hciconfig hci0 reset

(resets bluetooth adapter)

sudo invoke-rc.d bluetooth restart

(then restart it)

sudo bluetoothctl

(open bluetooth commandline)

scan on

( start scanning)

output looks like this:

(pair your mac address)
will output like this
