Bug#347468: ipw2200 in linux-image-2.6.15-1-686 lacks monitor mode
I upgraded to linux-image-2.6.15-1-686 and found that kismet no longer
worked. Neither could I set the card into monitor mode via iwconfig or
airmon. It's an ipw2915, which has worked more or less with various
ipw2200 drivers until today.
A quick check revealed that the ipw2200 driver had not been compiled
with Monitor mode support...it looks like this is set as an option in
the config file. No idea why it didn't result in a module with monitor
mode support ...but I was able to get monitor mode by installing the
ipw2200-source package, editing ipw2200.c and putting
at the top and using module-assistant to make a new module. Which is
probably not the brightest thing in the world but it works again.
