    Default Intel Wifi Link Drivers not working

    I have a lenovo x200 and have installed BT4 final and I can get everything working except for the wireless card. If I check the hardware that is being picked up it shows that my card is there. When i check the available drivers that are pre-installed the correct driver is there, but when I do a '/etc/init.d./networking start' the card just kinda hangs out and I get a "No DHCPOFFERS received"

    Any thoughts on this would be great.

    Maybe I am missing something simple but I just installed BT4 on my Lenovo x200 and have gotten everything else working except for the wireless card. If I look at the hardware the card shows up properly, but when I perform a '/etc/init.d/networking start' I get my ethernet connection to work but the wireless hangs and I get an error

    'no DHCPOFFERS reveived'
    No working leases in persistent database - sleeping
    if-up.d/mountnnfs[wlan0]: waiting for interface eth1 before doing NFS mounts

    I then check the network interfaces and I only have eth0 (working) and lo

    I also perform a ifconfig wlan0

    Link encap:Ethernet HWaddr xx:xx:xx:xx:xx:xx (shows up correctly)
    UP BROADCAST MULTICAST MTU:1500 Metric:1
    RX packets:0 errors:0 dropped:0 overruncs:0 frame:0
    TX packets:0 errors:0 dropped:0 overruncs:0 carrier:0
    collisions:0 txqueuelen:1000
    RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

    any thoughts

    Hi mate,

    I am having the exact same problem as you, I have been pulling my hair out for the last few hours about this so I am glad to see it is not just me.

    Hopefully someone will come along and point us in the right way!

    Have you established a connection via Menu > Internet > Wicd?

    Hey,

    It always comes up saying that there is no connections available, even though I am sitting practically right next to 2 AP's.

    Its not the gear as I have 3 computers accessing the AP's at the moment and they are fine, so the problem has to lie with backtrack, somewhere.

    You're not getting an IP address via DHCP. That's all your output messages are telling you.
    First once you've /etc/init.d/networking start then /etc/init.d/wicd start
    Once wicd starts you need to open its GUI. Go to Backtrack > Internet > Wicd
    If you have a hidden essid then you must go to the upper left hand corner and click the little arrow next to "Network". Click hidden network and enter your essid. You may need to refresh it a few times aswell.
    Also make sure to setup proper settings for your network and you have the option to set it to automatically connect.
    Then click connect.

    If all this still doesn't work try handing yourself a static IP and see if that resolves your issue. It can also be configured in wicd

    Hey guys,

    It appears Jeeves has changed what his original error message that was appearing was, although I am still having the issue hopefully someone might be able to help me out, saves me starting a new thread.

    This is the error i get when I try to run /etc/init.d/networking start:

    SIOCSIFFLAGS: No such file or directory
    SIOCSIFFLAGS: No such file or directory
    Listening on LPF/wlan0/00:1e:64:**:**:**
    Sending on LPF/wlan0/00:1e:64:**:**:**
    Sending on Socket/fallback


    Now I have a Wifi link 1000 series WIFI card, As far as I can tell it should be in the iwlagn driver set, but when I try and run airmon-ng start wlan0 it comes up with:

    Interface Chipset Driver

    wlan0 Intel 4965/5xxx iwlagn - [phy0]SIOCSIFFLAGS: No such file or directory


    Could this be a possible driver/firmware issue?

    Thanks

    Take a look at your logs, and any relevant messages in dmesg.

    So, I am assuming the you have done
    /etc/init.d/networking start

    Oh wait yes you have. When I did this I got the same thing. Just hit ctrl-c

    You can run iwconfig to verify that wireless drivers are in place.

    As trellis mentioned, start wicd, then you can run wicd-client. Nice interface. Lets you select which wireless interface to use (if more than one) configure wep, wpa, wpa2 whatever.

    The default setup is no networking started.
