    Default no ath0 in iwconfig

    I installed the Edimax EW-7318USg USB wireless dongle (into a Dell lattitude running BT3), compiled and installed the rt73 driver, but no ath0 is showing up in iwconfig (only eth0 & lo with no wireless extensions).

    Did I miss a step?

    Code:
    # lsmod | grep rt73
    rt73                  219264  0

    Try:
    ifconfig -a
    If it shows ath0, then type
    ifconfig atho up
    If it was eth1 instead of ath0, you should replace ath0 in the 2nd command with eth1.

    ifconfig -a only lists eth0 and lo.

    How does ath0 get created? Is ath0 supposed to be created when I type "modprobe rt73"?

    EDIT: also should mention, here is the output of lsusb:

    sometime simple unplugging & replugging the device solve the problem (while the machine id on). Try it..
    And, just in case, give us the output of
    iwconfig eth0
    &
    ifconfig eth0

    I'm logged in remotely from work, so I can't unplug the usb dongle until I get home tonight.

    But here is the output as requested (eth0 is hardwired to my router):

    # iwconfig eth0
    eth0 no wireless extensions.

    # ifconfig eth0
    eth0 Link encap:Ethernet HWaddr 00:06:5B:36:89:AC

    Back home now--- unplugging and plugging the usb dongle didn't make a difference, still nothing but eth0 and lo shows up with ifconfig/iwconfig.

    What would I need to do in addition to installing the driver with modprobe?

    if ifconfig ath0 up doesn't work, which it probably won't cause the kernel usually autoloads a wireless nic if it detects it, then you probably have the wrong drivers installed.

    I think bt4 comes standard with the rt73 driver why not give that a go?
    Using backtrack for the first time is like being 10 years old again with the keys to a Ferrari.

    2 reasons I can't try backtrack 4 right now:

    1) it's dvd only and the laptop has a CD drive that won't read dvds.

    2) backtrack 3 also apparently includes the rt73 driver (in /lib/modules/2.6.21.5/extra/). I tried that and also the rt73 driver that I compiled.

    What else can I try?

    You could also install BT4 on a USB stick and use that with the laptop. It should have a free USB port doesn't it?
