This isn't normal... Are you sure that it is what is eating the processor?

WEP is on the card not in the driver. There is no performance impact to speak of in enabling WEP. > Has anyone seen this issue ? Is it normal ? Could a better CPU (e.g. > 700Mh Duron) handle the whole 11Mbps bandwidth ? Something is amiss. I can get 4-5Mb/s through a ISA carrier without even thinking. That is on a 486/66, and the load is basically nothing... - Forrest W.
