    Default Aircrack Breaks Wireless

    After running Aircrack-ng all of my wireless interfaces are not found. In the past to resolve this issue I would boot into my Windows partition, but that isn't a solution because I don't run Windows anymore. This issue also effects my other Linux partition. My PCMCIA card works fine when I plug it into another laptop, but does not work in the laptop with Backtrack. This makes me think it is something on the firmware level and something in the Windows boot process fixes it.

    ifconfig eth1 up
    ERROR while getting interface flags: No such device
    lspci
    Network controller: Intel Corporation PRO/Wireless LAN 2100 Mini PCI Adapter (rev 04)
    /var/log/dmesg
    ipw2100: eth1: Firmware 'ipw2100-1/3.fw' not available or load failed
    ipw2100: eth1: ipw2100_get_firmware failed -2
    ipw2100: eth1: Failed to power on the adapter.
    ipw2100: eth1: Failed to start the firmware.
    lsmod grep ipw
    ipw2100 69768 0
    libipw 26712 1
    lob80211 5176 1
    Things I have tried.

    1. Rebooted
    2. Shut down
    3. Booted into different partition of Linux (same problem there)
    4. Turned off wireless in the BIOS, halted, booted, turned on in the BIOS and booted
    5. Ran ifconfig up and down
    6. Ran /etc/init.d/networking restart, stop, start and force-reload
    7. Removed the battery and power
    8. Ran iwconfig eth1 mode managed, monitor and master
    9. Used modprobe to remove then add the wireless module
    10. Checked the wireless on/off button on the laptop

    Any ideas?

    This problem happened right after you installed backtrack, or after you updated backtrack from the repos?

    Thanks for the reply. This issue happens after I run Airoscript. Before that everything works perfect. The strange thing is that it effects my other Linux partition and that is why I think it causes an issue on the lower levels.

    Do you have any other trouble shooting ideas? I have tried a bunch of things and spent hours searching for a solution. It would be great if I could find a solution, so in the future I don't have to reinstall if I run into it again.
