    Default bt4 wireless problem

    While this is my 1st post, i would like, first, to say a big HELLO to everyone here and a big THANKS for all of you that share your knowledge.

    I have a common problem but with no common solution - i suppose...

    I just install bt4 pre-final on my Toshiba Satellite L40 laptop, but the wireless does not work

    I have already try the following w/o success:
    1. sudo /etc/init.d/networking start
    2. I checked (by turning on and off) the wireless switch on my laptop. The result was that the led stays always ON...

    I should say that this is a triple boot laptop. I already have Vista and Fedora 10 and they both communicate with wireless perfect!

    In addition, I had try bt3 (based on slack) wireless setup with success: I had to use windows ndiswrapper drivers. I would like to avoid to install this drivers now.

    According to my small review on the problem, i found that bt4 is based on Ubuntu 8.XX which has problems to "see" my wireless (at least w/o mod). On the other had, Ubuntu 9.XX works fine with my wirless...
    by running lspci, I get the following:

    Which wireless card you have built-in laptop?

    Isnt wlan0 your wireless interface or its from usb wireless?

    If wlan0 is your wireless then:

    iwconfig wlan0 essid [your essid here] key [your key in hex]
    dhclient wlan0

    and it should you connect to internet!

    Handsome-geek thank you very much, you actually "push" me to the correct direction...
    My problem was the encryption type of my router, that was WPA2 and the ubuntu does not support it by default. In order to use WPA2 encryption i had to follow [sorry!! I cannot place a URL because of # of post restrictions]


    Just for the shake of the test, i change to WPA encryption and i install (from synaptic) the wireless lan manager (KWiFi manager).
    Thus, I connect to my router (with wap) using the KWiFi.
    The only problem is that i have to set the connection every time i logged in the my system by following the steps:

    Step 1.
    Activate my network using KWiFi: System | KWiFiManager | Settings | Configuration Editor: Enter Network name (SSID), check User Encryption and press Configure, then set the key1 with your hex password, check "Load preset.... at startup" and then press Activate!

    Step 2.
    Run
    # /etc/init.d/networking restart
