====== Trucs WiFi et Raspberry pi ======
===== Configuration a la main =====

  * en premier lieu : apt remove network-manager

On part de l'idée que la passerelle est 192.168.1.254

/etc/network/interface
<code>
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
#iface lo inet interface

allow-hotplug eth0
iface eth0 inet static
address 192.168.1.19

auto wlan0
iface wlan0 inet manual

wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
#hwaddress ether 00:13:ef:f3:01:99

iface default inet static
address 192.168.1.37
netmask 255.255.255.0
gateway 192.168.1.254

#source-directory /etc/network/interfaces.d
</code>

  * on peut faire un dhclient eth0 pour recupérer resolv.conf 
    * sinon y coller nameserver 192.168.1.254
  * ajout sur rc.local puisque il n'y a plus de network-manager

<code>
ifconfig wlan0 192.168.1.137
route add default gw 192.168.1.254 wlan0
</code>

  * wpa/supplicant/wpa_supplicant.conf
<code>
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=FR

network={
	ssid="SSID"
	#psk="0000000000"
	psk=ed1b74aaa1e8132bac8dcac8aaaaaaaaaaa9d1548d9caaaaaaaa4ddba
}
</code>
  de wpa_passphrase MYSSID passphrase
