[Madwifi-users] Framing Errors

[Kevin D. <kde...@ya...>]

Hi All,

I have an IBM Thinkpad T41p with the madwifi driver using CVS as of Feb=20

I seem to be getting lots of framing errors

My access point has a beacon rate of 100ms and is a DLink DWL-900AP+

The signal strength is good and I am only about 5 feet from the AP.

Is there something wrong with the CRC code perhaps? Should I try the other=
=20
rate manager?
