Im not sure if my question here is right and will be answered, but let's give it a try.
I got a IPW2200 Chipset in my Notebook, surely i got problems with packet injection. I found that little guide at the Ubuntu-Board which describes how to patch the drivers for PI.
All in all, something wrent wrong at the patch process and now the interface doesnt show up anywhere anymore
Could somebody please tell me the fastest way to "backup" the old drivers and getting it work again or give me a tut about it ?
thx for help !
