/etc/netowrk/interfaces issue.

[lilzz]

I use wpa-roam to setup my connection

case 1
iface wlan0 inet dhcp
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf

No IP has been assigned.

case 2
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf

Still no IP has been assigned

case 3
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp

now it works. why need to face default inet dhcp yet wlan0 has to be manual for wpa-roam to work?

Try this:
/etc/network/interfaces

Code: Select all

auto lo
#auto eth0
iface lo inet loopback
iface eth0 inet dhcp

allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet static
address 10.0.0.7
gateway 10.0.0.1
netmask 255.255.255.0

/etc/wpa_supplicant/wpa_supplicant.conf

Code: Select all

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

network={
        ssid="mySSID"
        scan_ssid=1
        psk="myRedactedPassword"
}

iface xxxx inet manual means that something external to Network Manager will be configuring the network. It's just the way it's designed to work.
