    Default Wireless Connection Problems

    In short, this is the message after running dhclient.
    ...
    No DHCPOFFERS received.
    No working leases in persistent database - sleeping

    What I have done:
    cat /etc/network/interfaces // to get interface
    auto lo
    iface lo inet loopback

    auto eth0
    iface eth0 inet dhcp

    auto ath0
    iface ath0 inet dhcp

    auto wlan0
    iface wlan0 inet dhcp

    I used wicd manager and it tells me "This network requires encryption to be enable.d" Is the encryption sshd?

    Questions:
    How am I supposed to get my Internet connection up?

    Where am I supposed to enter the password for my access point?

    What is the difference between ath0 and wlan0? Are they both wireless?

    How am I supposed to know what the nameserver is supposed to be?

    Default Wireless Connection Problems

    I am actually using backtrack but I got no ubuntu experience.

    In short, this is the message after running dhclient.
    ...
    No DHCPOFFERS received.
    No working leases in persistent database - sleeping

    What I have done:
    cat /etc/network/interfaces // to get interface
    auto lo
    iface lo inet loopback

    auto eth0
    iface eth0 inet dhcp

    auto ath0
    iface ath0 inet dhcp

    auto wlan0
    iface wlan0 inet dhcp

    I used wicd manager and it tells me "This network requires encryption to be enable.d"

    iwconfig reveals that my network is IEEE802.11bg ESSID "MSHOME" meaning network is detected.

    Questions:
    How am I supposed to get my Internet connection up?


    Where am I supposed to enter the password for my access point?
    (I am using a MiO box. Singaporeans will know what I mean)

    What is the difference between ath0 and wlan0? Are they both wireless?

    How am I supposed to know what the nameserver is supposed to be?

    You might to read http://www.backtrack-linux.org/forum...backtrack.html
    And not just the first page.
    "The difference between RAID1 and RAID0 is that the zero stands for how many files you're gonna have after a harddisk failure."

    I'm fairly new to backtrack but I'll try to help.

    when backtrack starts up type the following:

    /usr/bin/start-network
    startx

    That will start "Wicd" network manager.

    When the GUI starts up, you'll see a little network icon in the taskbar, click on it. In the window that opens up, you can hit "refresh" if needed to scan for your AP. When it finds it, you can click the little arrow below it to get to prefrences. From there you can select encryption type such as wep or wpa, ect and enter your key there. That should fix you up. If not you might have to play around with the preferences in wicd a bit. Hopefully this helps.

    What wireless card/chipset are you using.

    What type of encryption are you using on your network?
    For WEP use iwconfig 'insert interface here' enc ********** or iwconfig 'insert interface here' key **********
    For WPA you will need to use WPA_supplicant

    I'm a compulsive post editor, you might wanna wait until my post has been online for 5-10 mins before quoting it as it will likely change.

    I know I seem harsh in some of my replies. SORRY! But if you're doing something illegal or posting something that seems to be obvious BS I'm going to call you on it.
