[Solved] Can't get wifi to Work on pi5

[Rabie]

Installed extensions:

Code: [Select]

wireless-KERNEL.tcz (wireless-6.12.25-piCore-v8)
wifi.tcz
firmware-rpi-wifi.tcz
wpa_supplicant.tcz

Code: [Select]

ifconfig:
wlan0     Link encap:Ethernet  HWaddr 88:A2:9E:30:AD:A2
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0

Code: [Select]

sudo wifi.sh
Found wifi device wlan0
Standby for scan of available networks...
wlan0     Interface doesn't support scanning : Connection timed out

When I create the file /etc/wpa_supplicant/wpa_supplicant.conf with the following content:

Code: [Select]

ctrl_interface=DIR=/var/run/wpa_supplicant
update_config=1
country=DE

network={
        ssid="my ssid"
        scan_ssid=1
        proto=RSN WPA
        key_mgmt=WPA-PSK
        pairwise=CCMP TKIP
        group=CCMP TKIP
        psk="my password"
}

and then run the following command:

Code: [Select]

sudo wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf

I get this output:

Code: [Select]

Successfully initialized wpa_supplicant
wlan0: CTRL-EVENT-REGDOM-CHANGE init=USER type=COUNTRY alpha2=DE
wlan0: Failed to initiate sched scan
wlan0: Failed to initiate sched scan
Any Help?
Thank you

[Juanito]

I'm using this:

Code: [Select]

ctrl_interface=/var/run/wpa_supplicant
country=FR

network={
        ssid="Livebox-62BC"
proto=WPA2
psk="password"
}
..and things work fine on an RPi5.

Do the last twenty or so lines in dmesg give any hints as to the problem?

[Rabie]

if i try with your configs i get:

Code: [Select]

sudo wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf
Successfully initialized wpa_supplicant
nl80211: kernel reports: Registration to specific type not supported
wlan0: CTRL-EVENT-REGDOM-CHANGE init=USER type=COUNTRY alpha2=DE
wlan0: CTRL-EVENT-SCAN-FAILED ret=-110 retry=1
i suppose it has something to do with the power save mode for wlan0 ?

If you using a router with the correct country code, the country code will be sent to the client.
You don't need to set the country_code anymore in the client.
Here some examples of commands i use, to set and get the country code if the router not send the correct one. The standard being used is https://en.wikipedia.org/wiki/IEEE_802.11d-2001
You can check this if you want, just set the country code to 00(not set), and then connect to the router
and then show what country code being used by iw reg get command, and then disconnect and see that it comeback to unset.

I have to "deal" with this long time now, with my Asus router.
That not send the correct one and not set the correct one itself.

Code: [Select]

iw reg set SE
iw reg get

Happy hacking, please don't break the law, by using wrong country code.

[Rabie]

no matter if with country or not, its not working

Code: [Select]

cat /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant

network={
        ssid="my ssid"
        proto=WPA2
        psk="my password"

Code: [Select]

sudo wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf
Successfully initialized wpa_supplicant
wlan0: CTRL-EVENT-SCAN-FAILED ret=-110 retry=1
wlan0: CTRL-EVENT-SCAN-FAILED ret=-110 retry=1

[patrikg]

And are you pasting not the hole file, you are missing the last "}"
And do it more simpler and just this between the lines.
----------------------------------------------------------
ctrl_interface=/var/run/wpa_supplicant

network={
        ssid="my ssid"
        psk="my password"
}
----------------------------------------------------------

Are you using a hidden ssid ?
You also have to add

Code: [Select]

scan_ssid=1

[Rabie]

no i am not using a hidden ssid.

ist was the hole file but maybe didnt copy the last "}"

Code: [Select]

ctrl_interface=/var/run/wpa_supplicant

network={
        ssid="my ssid"
        psk="my password"
}
also with the simple conf i still get:

Code: [Select]

sudo wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf
Successfully initialized wpa_supplicant
wlan0: CTRL-EVENT-SCAN-FAILED ret=-84 retry=1
wlan0: CTRL-EVENT-SCAN-FAILED ret=-84 retry=1


does this logs help?

Do you get it working with another distro ?
Like Raspberry Pi OS Lite or the light weight Alpine Linux.
https://downloads.raspberrypi.com/raspios_lite_arm64/images/raspios_lite_arm64-2025-10-02/2025-10-01-raspios-trixie-arm64-lite.img.xz

https://wiki.alpinelinux.org/wiki/Raspberry_Pi

And what router are you using ? 2.4GHZ 5GHZ
You can try to connect to your mobile phone internet sharing ?

[gadget42]

iirc, i seem to remember inadequate power supply being an issue with some types of deficiencies?

[Rabie]

i took a guess and added the command for wpa_supplicant to /opt/bootlocal.sh so it maybe associate while booting

Code: [Select]

wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf&
and guess what it worked!

After booting is over i ran:

Code: [Select]

sudo udhcpc -i wlan0
and i got the ip configs i was expecting.

I dont really unterstand why, but it worked like this

[Rabie]

this topic can be marked as solved i think.

Thank you for helping

Hi Rabie

i took a guess and added the command for wpa_supplicant to /opt/bootlocal.sh so it maybe associate while booting ...

 ... I dont really unterstand why, but it worked like this

If you want to try to pinpoint where the problem is occurring, you can try a couple of simple tests.

bootlocal.sh runs as root. Instead of:

Code: [Select]

sudo wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conftry running it as root like this:

Code: [Select]

sudo su
wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.confand see if the command now succeeds.

To see if it's something later in the boot process causing this, change bootlocal.sh to this:

Code: [Select]

sleep 30
wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf&and see if the problem returned.

Hi Rabie

this topic can be marked as solved i think. ...

Done.

[Rabie]

Hi Rich, i will look into that.

i am still haven some problems with the wifi.

After rebooting its sometime work and sometime i get errors that the driver isn’t right.

If you can provide me a little guide how to set up the wifi from start, that would be great.
Maybe i am doing something wrong

[patrikg]

There also some notes in the wiki:
https://wiki.tinycorelinux.net/doku.php?id=picore:wifi

Maybe @Rich can add some more text to it.
