Hi,Pi3B, Can’t set Country from Raspi-config

erv93

RetroPie image downloaded from RetroPie for Pi3
Regular power 2.5A
7inch screen HDMI

“No wireless interface found” in country set
“No wireless interface found” in Wi-Fi menu trying to scan

Attempt to Set Wi-Fi and Country for Wi-Fi before :
-Via raspi-config
-By wpa_supplicant config in boot/
with manual edit i added Country=US

In IfConfig—-> Wlan0 doesn’t show up
In Ip show address —-> wlan0 is not present
Only Lo and Ech0

I’ve checked also boot/config.txt if there’s some issue in there but nothing .
I have a tenda U3 dongle Wi-fi if someone knows how to install on RetroPie

How can I bypass the problem with the country set?
Could be an Hardware issue?

thank you all

Looks like your issue is the WiFi adapter is not detected/supported out-of-the-box, it may need a driver to be installed in order to show be detected.

Any reason you're using a WiFi dongle instead of the built-in WiFi ?

@mitu Because with the default option I ve tried to set the country to enable the Wi-Fi on board in RetroPie and it gaves me “ no interface found”.

So I tried to avoid the problem using a dongle Wi-Fi and in Lsusb it show up but I think it need driver.

However the problem is still there even if I edit the spa supplicant config

I add one thing : I checked if network. Service is working and it does

Today I will try to install RetroPie image on another Sd card and Raspbian Os in another Sd card to check if the problem is on the sd cards or image corruption

If the LAN cable is plugged in, the WiFi is not started on RaspiOS. Is your Pi connected to the LAN cable when you start the WiFi configuration ?

@mitu no I’m working on raspberry stand-alone with keyboard and the 7inch screen .No ssh connection and No putty

mitu

Can you run

sudo rfkill list all

and post the output ?

erv93

it shows really nothing

pi@retropie:~ $ sudo rfkill list all
pi@retropie:~ $ sudo rfkill list all

@mitu if i put an external bluethoot dongle it show up
like it deserve to be

Bluetooth is a bit different and most likely the adapter on the dongle is supported by RaspiOS out-of-the-box. It's strange that rfkill doesn't show any adapters present, it should print something like:

pi@retropie:~ $ sudo rfkill list all
0: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no

If the WiFi is blocked by the country selection, it would print:

pi@retropie:~ $ sudo rfkill list all
0: phy0: Wireless LAN
	Soft blocked: yes
	Hard blocked: no

Did you modify the boot loader configuration (the config.txt file on the boot partition from the SD card) ? Can you post the contents of config.txt here ?

@mitu
I ve tried with another Sd card with a fresh image of rasp os raccomanded writed with raspberry image maker for rpi3 .
Countyset in settings disabled
Default config.txt
If config —-> no Wlan0
Rfkill list all —-> No wireless adapter showed
Lsusb—-> it’s showed the network wifi adapter

So I suppose it’s not the Sd card or the Image
With both Raspbian and RetroPie there aren’t network interfaces integrated of rp3 On
The Wi-Fi dongle shows up only in Lsusb not in rfkill
The rfkill command isn’t showing soft blocked or hardblocked interfaces on RetroPie and rasp os

Hardware issue ?
