Hi everybody, Following the instructions reported on the Debian unofficial port home-site [1] I successful installed Debian on raspberrypi 3B 2016 all works fine for my needs but configuring the built-in wi-fi interface apparently it works but reporting errors:
~# ip addr show dev wlan0 3: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000 link/ether b8:27:eb:8b:10:67 brd ff:ff:ff:ff:ff:ff ~# ifup wlan0 RTNETLINK answers: File exists ifup: failed to bring up wlan0 the ifup command reports that it fails to bring up but the interface is configured: ~# ip addr show dev wlan0 3: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state DORMANT group default qlen 1000 link/ether b8:27:eb:8b:10:67 brd ff:ff:ff:ff:ff:ff inet 192.168.0.9/24 brd 192.168.0.255 scope global wlan0 valid_lft forever preferred_lft forever if I try to de-configure the interface it fails: ~# ifdown wlan0 ifdown: interface wlan0 not configured How can I de-configure wlan0 and why do I get errors when I bring up with ifup command? Some useful information about my configuration: ~# cat /etc/network/interfaces.d/wlan0 # allow-hotplug wlan0 iface wlan0 inet static address 192.168.0.9 netmask 255.255.255.0 network 192.168.0.0 broadcast 192.168.0.255 gateway 192.168.0.1 wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf ~# cat /etc/wpa_supplicant/wpa_supplicant.conf ctrl_interface=/var/run/wpa_supplicant update_config=1 network={ ssid="myessid" psk=dfd452fedacd69d6d54582770dc93acebfb6f2ec2aac7d2e3f24e6ecacafc487 } ~# systemctl is-enabled wpa_supplicant disabled Thanks for any answer, best regards.
