no wireless interface when clicking on dhcpcd icon in top

[Quantu]

when i click the dhcpcd's "Wireless & Wired network" icon i get "No wireless interfaces found"


this is my interfaces file:

interface wlan0

interface eth0

i have no clue what is going on i have hostapd installed and i tried to make an AP but i think i screwed up real bad
as you can see i also removed some private stuff
update before post: i removed hostapd

update2:

lo no wireless extensions.

eth0 no wireless extensions.

its very weird how dmesg | tail shows that brcmfmac doesnt have power management on while iwconfig shows its on

Your addenda to dhcpcd.conf make me ask, if your were not better off without them. What's your rationale to put them there?
So I would try to do without them, then toggle rfkill, then sudo ifdown wlan0 sudo ifup wlan0 and again toggle rfkill for good measure. Then reboot, back in the GUI turn off wifi and on again. This worked for me when wifi suddenly diappeared for no known reason. To be honest, I have no clue what happens EXACTLY behind dhcpc5 and the GUI. When everything else fails I even had to uninstall/purge dhcpcd5 and setup my wifi from the CLI old school as described here https://www.raspberrypi.org/documentati ... ess-cli.md

can i configure with oldschool method before i remove dhcpcd5? (without activating wlan0 yet)

update:
root@RaspPi:/home/pi# ifup wlan0 & ifdown wlan0

Hi Quantu,
I made mixed experiences. So you might be able to configure your wlan from the CLI with dhcpcd5 present, but it is as likely that you might not succed. So what hinders you to uninstall dhcpcd5? You can reinstall it any time later should you want to.

If it were my Pi I'd have a closer look at /etc/network/interfaces and /etc/wpa_supplicant/wpa.supplicant.conf These files I would strip to the bare minimum e.g.

Code: Select all

auto lo
iface lo inet loopback

allow-hotplug wlan0
iface wlan0 inet dhcp
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

and for the wpa_supplicant.conf

Code: Select all

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

network={
        ssid="my AP"
        psk="my passwd"
        key_mgmt=WPA-PSK
}

With these I'd do a reboot and have a look at the output of dmesg, ifconfig.
You might want give it a try and post the outcome.
Greetings

well i tried to de-install dhcpcd5 and it worked but for some reason no connection works anymore :/. when a new raspbian distro update comes out ill wipe my sd card (all my important files are on my usb ) and install that one.
