iwconfig
sudo iwlist wlan0 scan

Thanks.

dmesg | grep wlan0

Have you done:

sudo apt-get install linux-backports-modules-hardy-generic

What are your specific issues? Just unable to connect?

[sander demeester]

output command :

sudo apt-get install linux-backports-modules-hardy-generic

well, i cant see me wifi network (wpa protecetd) i cant configure me wireless network card, and i cant connect to it. i cant do anything with me wifi card. ive read about a bug in the kernel that iwl3945 module cant load, i tought it had something do to with that.

[chili555]

that iwl3945 module cant load

I doubt it, but I guess anything is possible. Let's check to be sure:

lsmod | grep iwl3945

If a lot of text comes back, like this:

iwl3945                93940  0 
iwlwifi_mac80211      219108  1 iwl3945
led_class               6020  1 iwl3945

Then it's loaded.

Do you have an active wired ethernet connection? Network Manager will not activate wireless, if wired is available: https://help.ubuntu.com/community/Wi...NetworkManager If you reboot with the wire detached, is your wireless available to be configured?

May we please see:

sudo cat /var/log/messages | grep switch

i have some problems with me wifi card for 2 mounth now

Please do not wait two months before you consult us. We are here to help.

i just notice that

sudo apt-get install linux-backports-modules-hardy-generic

made the kill switch led work as was promised somewhere, but that was all.

sudo iwlist wlan0 scan

lists all networks and infos, but i cant find a way to see any network in the network manager or anywhere else so i could connect to them

[chili555]

Do you see your wireless interface in System -> Administration -> Network after you unlock? Is the Enable this connection box checked? It needs to be unchecked for Network Manager to manage your connection.

i noticed that. i've tried with roaming mode (wireless interface unchecked) and with configuring my wlan by checking the interface and giving ssid/password there. neither works..
