Banging my head accessing my wifi

[malat]

Hi there,

  I am trying -yet again- to access wifi from my debian/stable box. I
gave up on using NetworkManager  since it does not even scan or list
available networks.

  I added the following line to  /etc/network/interfaces:

# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp

+ iface wlan0 inet dhcp
+        wpa-ssid NEUF_XXXX
+        wpa-psk thepassword

Which should be started using:

$ sudo ifup wlan0

I am using a default debian installation with GNOME, what tool can use
to actually get anywhere (at least get informative debug info).

Thanks,

Does this mean the radio switch is in the "off" position? ^^^^^^^^^^^^^^

I do not understand what you mean. How do I turn this thing on ?

You don't say what kind of computer you have, but many laptops have an
actual switch on the edge of the computer that is used to turn on/off wifi
and Bluetooth.  I know my Thinkpad does.

It's a physical switch on the laptop. Everyone does it differently. On
my T61 it's on the left front. Somewhat looks like a lid latch release.
On a Toshiba I had it was also on the left front, but much smaller. What
is the make/model of the laptop in question?

Failing that, my "HW RF Kill switch" on this Inspiron E1505 is Fn+F2; F2 has a
blue picture of a tower with "radio waves" coming out of it.  I think it is
odd that my HW (hardware) switch only works when my computer is on, and
probably involves SMM (system management mode) part of my BIOS software.

The first thing to make sure is that your router's MAC filtering isn't
on (and filtering your WiFi card out). The next thing is to disable all
security settings in yor router and your card (there'll be plenty of
time to set wpa keys later on, if and when you get the thing working).
Then, put the right commands in your e/n/i. Let me give you the
relevant snippet from my e/n/i which WORKS:

<snip>

# This was added by me to override DHCP and set a static IP
allow-hotplug wlan0
iface wlan0 inet static
        address 192.168.2.123
        netmask 255.255.255.0
        gateway 192.168.2.1
        wireless-essid Type_your_ESSID_here

</snip>

Of course, this is a static configuration; if you want DHCP, then you
just leave out *any reference* to your wirelles interface in e/n/i.
That way, NetworkManager will take over and hopefully configure your
wireless on-the-fly.

use iwconfig to see what status your card is in

/sbin/iwconfig
lo        no wireless extensions.

eth1      no wireless extensions.

wmaster0  no wireless extensions.

 Tx-Power=off means power is disabled (kill switch is off)

you can activate this by the Fn+F<x> combination or hardware switch and with
iwconfig wlan0 txpower 15

At least this means the hardware thingy is ON. Now I cannnot switch it
off using the Fn+F<x> comb, I am guessing I am not using the right
keyboard map...

Long story short, I was trying to access a sfr/neuf box. It comes with
two network: NEUF_wifi & NEUF_XXX
I was able to access the NEUF_wifi (public) without problem, this
means hardware was ok. But then I could not access NEUF_XXX.
On the back of the hardware device the WPA-PSK is written in clear
(don't ask). From the begining I thought I could use that...until I
actually connect to the interface (192.168.1.1) and discover that it
was setup to be WEP (with a substring of the password written on the
back of the hardware).
Changing to WPA-PSK, made everything work as expected.

Sorry for the noise, but I discover hal-info the in the process :)
