Re: ipw2200 low performance

Hi!

Sorry for this. The mouse went faster than me :-)

The problem you get with the bandwidth discrepancy between Linux and windoes 
is quite odd. Theoretically it should be the same. But the driver 
architecture for Linux developed by the Intel's team is quite different from 
the one embedded in windoes systems. There are hundreds of reasons for the 
phenomenon you currently encounter.
I may be wrong and other more qualified people on this mailing list may give 
you another reason. It may come from the type of encryption you use. A very 
high level of encryption may reduce the bandwidth. You may have a low 
encryption on windoes, i.e. WEP, and a better and more secure encryption on 
Linux, i.e. WPA2 with AES. This may be one the reasons.
You can try to set up the same encryption for both systems and check the 
bandwidth results are.
Did you install the latest stable version of IPW2200 driver and firmware on 
Linux?
Sorry if my explanation is of any help but the information you provide about 
your settings is vague.

Cheers,
