I've loaded up backtrack 3 on my Gateway laptop.
Intel 4965 -- iwl4965 driver

Once I stop the driver, change the mac address, then try to start it, I get this error

ERROR: Neither the sysfs interface links nor the iw command is available.

I've searched for forums and found most answers for iwl3945 but not iwl4965. Although I DID try to solution for 3945 to no avail. I've uninstalled the iwl4965 driver through spoonDRV as well as modprobe -r iwl4965, Try installed the raw driver, but that didn't work either. I tried to go ahead even with this error, although once I get to the ARP, I get no ARP's, even when I connect another computer to my router and download a large GB file through wireless. Here's a little bit of data from my session.

wlan0 IEEE 802.11g ESSID:"" Nickname:""
Mode:Monitor Freq:2.412

bt ~ # modprobe -r iwl4965
bt~ # iwconfig
lo no wireless extensions.
eth0 no wireless extensions.

bt~ # modprobe ipwraw
bt~ # iwconfig
lo no wireless extensions
eth0 no wireless extensions

--- Loading the ipwraw didn't seem to load the driver.
Any suggestions. Is my wireless card supported or should I be buying a new card for this laptop to do this? Let me know anything else to try. Thanks!
