Good morning!
Today i ve done an update/upgrade on my raspi.
After restarting no wlan-connection is established.
I ve checked /etc/network/interfaces but all is like
it was. Any ideas?
Thats my /etc/network/interfaces:
Code: Select all
iface lo inet loopback
iface eth0 inet dhcp
auto wlan0
allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-ssid "xxxxx"
wpa-psk "xxxxx"
Regards
Oliver

Hello Oliver,
here's the content of my /etc/network/interfaces (I never changed it, it's the default), but instead of modifying /etc/network/interfaces, I modify /etc/wpa_supplicant/wpa_supplicant.conf (second file below) - I followed explanations found on Internet.
pi@raspberrypi:~ $ cat /etc/network/interfaces
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
auto lo
iface lo inet loopback
iface eth0 inet manual
allow-hotplug wlan0
iface wlan0 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
allow-hotplug wlan1
iface wlan1 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
pi@raspberrypi:~ $ sudo cat /etc/wpa_supplicant/wpa_supplicant.conf
Code: Select all
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=FR
network={
ssid="put your ssid here"
scan_ssid=1
key_mgmt=WPA-PSK
psk="put your password here"
}
NB : country=FR has been added automatically by sudo raspi-config (Internationalization options / Wifi country).
Regards,
GD

Hello and thx for your answer.
I will give it try and report the result.
I also did it like explained in the internet but i think there are a few way to setup the WLAN.
Are you using DHCP or a static IP?
If static, configured via your router or raspi?
Regards
Oliver

Hi OCB73,
I use DHCP, but I configured my box (box administration, option DHCP or DHCP serveur) so that the same IP adress is always attributed to the 'MAC Adress' of the wifi card of the raspberry).
Usually the box shows the mac adress of any equipment connected to it, you may see it also on the raspberry as the HWaddr given by the command :
See you,
