[SOLVED] Wifi problems in chimaera in raspberry pi 4

I had to reinstall devuan chimaera in a ssd for my raspberry pi 4. Now I'm not able to see wifi connections.

I installed wicd, in the wireless section it says something like "the device is not ready" (translation, it's in spanish). Trying with nmcli dev it says:

DEVICE  TYPE      STATE          CONNECTION      
eth0    ethernet  connected      Ifupdown (eth0) 
wlan0   wifi         unavailable  --  

With [iw]iw[/iw] sometimes I even see the SSID of the nearest wifi connections available, some other times it says

command failed: Device or resource busy (-16)

.

I've tried changing the configuration in wpa_suplicant configuration, but there is no difference.

Does anyone had have this same problem? When I installed on a sd card didn't have this trouble.

Is wlan0 listed in /etc/network/interfaces? If so then NetworkManager will ignore it.


To obtain a root shell use su -. Using just su will result in "command not found" messages.

Yes, it's listed in /etc/network/interfaces:

### Wifi
allow-hotplug wlan0
iface wlan0 inet dhcp
	wireless-power off
	#address 10.0.0.10
	#netmask 255.255.255.0
	#gateway 10.0.0.1
	#dns-nameservers 8.8.8.8 8.8.4.4
	wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

wpa_suplicant.conf contents the next lines:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
p2p_disabled=1
country=US

network={
	ssid="ssid_private_network"
	scan_ssid=1
	key_mgmt=WPA-PSK
	psk="passphrase"
}

Should I comment wlan0 in the /etc/network/interfaces?

Re: [SOLVED] Wifi problems in chimaera in raspberry pi 4

I found it, thanks for the advice. Yes, I just commented the lines about wifi in /etc/network/interfaces.

So I make a small summary about this. I installed chimaera in an ssd via the raspberry pi imager. Follow the instructions to install xfce given in:
https://www.devuan.org/os/documentation … stall.html (there's a spanish version https://www.devuan.org/os/documentation … stall.html).

In my case I needed to install xinit too, but everything else is complete.

After that installed network-manager with some extras to make it more comfortable. And just commented the line before mentioned. And it works.

Thanks

Re: [SOLVED] Wifi problems in chimaera in raspberry pi 4

I think dumping NetworkManager and using /etc/network/interfaces would make more sense on a Raspberry Pi. Or anything else for that matter.
