I do not know why, but when I unplug my ethernet cable, I have no more wifi connection. I use /etc/network/interfaces for configure my static IP
auto lo
iface lo inet loopback
allow-hotplug eth0
iface eth0 inet static
address 192.168.XXX.XX0
netmask 255.255.255.0
gateway 192.168.XXX.XXX
allow-hotplug wlan0
iface wlan0 inet static
address 192.168.XXX.XX1
netmask 255.255.255.0
gateway 192.168.XXX.XXX
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
And my wpa_supllicant.conf is correct
Does anyone know why? Thanks
