Start wireless network automatically on boot-up - how to?

Question

With the great help in WLAN using Netgear WNA1000M fails - what am I doing wrong? I managed to get my wireless network working on Raspbian running on my RPi.

But - I need to manually run the wpa_supplicant command

wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf -Dwext

in order to connect to the wireless network. Once I run this command, an IP address is automatically received via DHCP and everything is fine.

It's just not working automatically when I boot.

How do I change this?

My /etc/network/interfaces file looks like this:

auto lo

iface lo inet loopback
iface eth0 inet dhcp

auto wlan0
allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf

iface default inet dhcp

Am I missing something in here?

Answer 1

I got it.

I had to replace wpa-roam by wpa-conf.

If anyone could explain why, I'd be happy ;-)

Answer 2

I am not sure why you needed to replace wpa-roam with wpa-conf. I have a wireless lan adapter (as I assume you do too -- wlan0 implies as much).

My setup checks for and connects to a configured network when booting. I am attaching the file below for your consideration.

auto lo

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 dhcp
