No wireless interfaces found

Wed Jan 24, 2018 5:26 pm

Hi guys
I just installed the newest rasbian on my PI 3 and I'm facing some issues with WLAN. The WLAN itself works and connects to my home network, but the icon on the systembar is two red X's and I can't see my signal, nor scan for other networks.

Here's my /etc/network/interfaces file

Code: Select all

auto lo

iface lo inet loopback
iface eth0 inet dhcp

auto wlan0

allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp
And here's my wpa_suplicant.conf file

Code: Select all

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



network={
        ssid="xxxxxxxx	"
        psk="xxxxxxxxxx"
        proto=RSN
        key_mgmt=WPA-PSK
        pairwise=CCMP
        auth_alg=OPEN
}
Like I said..i got internet/wlan connection it's just this icon on the bar that seems to be broken. As soon as I get my mouse over it a balloon tip appears "Connection to dhcpcd lost" and when I actually click on it it says "No Wireless interfaces found"
Any ideas on that ?

With the latest versions of Raspbian, Raspbian Stretch, you should not edit file /etc/network/interfaces to configure your wifi. You only need to set up the wifi using /etc/wpa_supplicant/wpa_supplicant.conf.

The problem with the wifi icon is probably down to that.

Put file /etc/network/interfaces back to its default state.

Code: Select all

# interfaces(5) file used by ifup(8) and ifdown(8)

# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'

# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d
and reboot. You should get a wifi connection and maybe your wifi icon will now work as expected.

Good to hear your problem is now sorted.

Wasn't sure my suggestion would work but nice to find out it fixed your problem.

Hi, I have the same exact problem. I open the /etc/network/interfaces file and it says

Code: Select all

# This file is auto-generated by openmediavault (https://www.openmediavault.org)
# WARNING: Do not edit this file, your changes will get lost.

# interfaces(5) file used by ifup(8) and ifdown(8)
# Better use netplan.io or systemd-networkd to configure additional interface stanzas.

# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d
Of course I use the Pi4 as a NAS, and I installed OMV and set an static IP. Should I edit the file? THere is also another file calle "interfaces.bak"
I don`t know if I should edit the file, I can´t even edit it with Mousepad.

I´m a noob, thanks for your understanding and patience.
