    Re: wireless problems(iwlwifi)

    Let's see if we can figure out exactly which Intel device you have and if we can get the correct driver and firmware to load manually with modprobe

    Code:
    sudo lshw -C network
    Personally I wouldn't jump into compat modules or source builds until I'd explored all other avenues - it will make your system harder to maintain if you go that route

    Re: wireless problems(iwlwifi)

    I suggest you try going back to the compat-wireless package and do:
    Code:
    cd /media/B0008017007FE330/
    cp compat* Desktop
    I don't know if 'media' is a CD or a USB key or what, but it's generally preferable to work on a location on your harddrive rather than removable media. Now do:
    Code:
    cd ~/Desktop/compat-wireless-2.6.32.16/
    sudo su
    make clean
    ./scripts/driver-select restore
    ./scripts/driver-select
    You will want either iwlagn or iwlwifi, whichever it's called.
    Code:
    ./scripts/driver-select iwlwifi <--or whichever you saw above
    make
    make install
    Any errors? If so, I then suggest you try the later compat here: http://linuxwireless.org/download/co...reless.tar.bz2

    I will be traveling for the next 24 hours or so. I'll look for your report then.

    Let's be sure the version you compiled covers your device:
    Intel Corporation Device [8086:0888]
    Code:
    modinfo iwlwifi | grep 0888
    Also please post:
    Code:
    iwconfig
    rfkill list all
    dmesg | grep iwl
