Question How to connect to my wireless WPA-PSK home network?
Hi. I have a WPA-PSK secured wireless home network. I can connect to it in Windows, but I did not get it working in Debian. I have wpasupplicant installed and I don't know what the problem is. Maybe you can help me with the information below.

Thanks!

That line sets a WEP key, not a WPA key. To connect to a WPA secured network requires you to use something like wpa supplicant. You don't mention which distribution you use, but it's a fair bet that it would be included if it's something reasonably modern.

Some judicious web searching should give you everything you need, and if you run into problems you can always ask us here.

Let us know how you get on,

Chris...

P.S. Kudos for providing lots of info about what you have tried already, it makes for a great question.

Hi Chris,

Thanks for helping out. I'm using Debian Etch (as I've mentioned!).

I did some googling and this is as far as I got.

Below you can see I used wpa_cli. In the example below scan did not find any network, but a reboot or two before this, it actually did find some SpeedTouch network which is not mine. But my network is not found.

What am I doing wrong?

First, my interfaces file:
Code:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# This is a list of hotpluggable network interfaces.
# They will be activated automatically by the hotplug subsystem.
#mapping eth1
#	script grep
#	map eth1

# The primary network interface
#allow-hotplug eth1
#iface eth1 inet dhcp

#iface eth0 inet dhcp

iface wlan1 inet static
address 192.168.1.66
netmask 255.255.255.0
gateway 192.168.1.254
wpa-driver ndiswrapper
wpa-conf /etc/wpa_supplicant.conf

auto wlan1
And my wpa_supplicant.conf:
Code:
# allow frontend (e.g., wpa_cli) to be used by all users in 'users' group
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=users
#
# home network; allow all valid ciphers
network={
	ssid="CasaNova"
	scan_ssid=1
	key_mgmt=WPA-PSK
	psk="my_password"
}
Here's what I've tried:
Code:
schmauck:/home/daan# iwconfig

eth0      no wireless extensions.

eth1      no wireless extensions.

Oops, -1 for reading comprehension.

Can I get you to try the following as root:

Code:
killall wpa_supplicant
wpa_supplicant -i wlan1 -c /etc/wpa_supplicant/wpa_supplicant.conf -D ndiswrapper -d
That should kill off any running instances of wpa_supplicant and then start a new one that prints out lots of debug messages. You'll hopefully get something like this

Quote:
EAPOL: SUPP_PAE entering state AUTHENTICATING
EAPOL: SUPP_BE entering state SUCCESS
EAP: EAP entering state DISABLED
EAPOL: SUPP_PAE entering state AUTHENTICATED
EAPOL: SUPP_BE entering state IDLE
If there are errors then post them here so we can take a look.

Also, can you run these commands so we can see the active network settings.

Code:
route -n
cat /etc/resolv.conf
iptables -L
This should let us see what the problem is.

Let us know how you get on,

Chris...

As you can see, I hit Ctrl-C after the wpa_supplicant command, because I thought it would not stop by itself.

It works now
I have a connection now.

I followed these instructions for my specific Wireless adapter (NETGEAR WG111v2) with Ndiswrapper. They are for Ubuntu Feisty Fawn, but they work on my Debian Etch. It involved using the WIN98 drivers. Also my interfaces file now has a line "wpa-driver wext" in stead of "wpa-driver ndiswrapper". I also have my key now in hex and not ascii and there are some other changes.

[SOLVED] problem with NETGEAR WG111v2 - Ubuntu Forums

I have not yet rebooted, but the guy who wrote the instructions says he has to manually

Code:
/etc/init.d/networking restart
after each boot. Should be fixable, right?

Anyways, thanks for your help, Chris!
