Good point. I did not take into consideration the wireless encryption
being done. Using ttcp I got these results:

11M  =  4.48 Mbit/sec +++
54M  =  8.68 Mbit/sec +++

On a regular 10/100 NIC I get 87.03 Mbit/sec +++

With or with encryption overhead that is significantly faster than the
wireless connection. 

Any ideas?

Thanks,
James
