AFAIK WM Recorder doesn't work with wireless adapters in the ADA mode (I'll ask the developer to make sure).

It must be caused by the fact that WinPCap doesn't work with wireless adapters. But WinPCap didn't work with dial-up adapters either and now I can even use WM Recorder in the ADA mode on a dial-up!

Please try PRO mode instead. The latter is a little bit less reliable compared to ADA mode, but still gives very good results.
