    wireless driver problems

    so i was following this guide trying to setup my wireless driver
    http://www.aircrack-ng.org/doku.php?id=compat-wireless

    and at the end i type sudo modprobe "driver-name"... i tried inserting iwl3945,mac80211, and other drivers instead of driver -name but with no success...

    when i do and iwconfig i see no listing of wlan0 anymore... i think i messed up badly can anyone help me fix this ??

    Re: wireless driver problems

    If the built-in iwl3945 is not working, something else is wrong. Check to see your wireless device:
    Code:
    lspci -nn | grep 0280
    For example:
    Intel Corporation Centrino Advanced-N 6200 [8086:4239]
    Search for the pci.id and see what driver is needed. Is it iwl3945? Check the message logs for clues:
    Code:
    dmesg | grep iwl <--or your driver if not iwl3945
    See if the hardware switch is set to enable wireless:
    Code:
    rfkill list all
    I will be in and out today, so I may not answer immediately.

    You have an unhappy driver there. You need to remove the compat package:
    so i was following this guide trying to setup my wireless driver
    http://www.aircrack-ng.org/doku.php?id=compat-wireless
    I know nothing about aircrack but compat and the built-in iwl3945 often don't play well together.
