Our team has not investigated the issue further yet but I suspect that the bus' speed of PCMCIA is the issue. Have you faced this? (express cards or USB2.0 don't have this issue) Philippe On Apr 27, 2009, at 8:42 AM, Barber, Matt wrote: > Hi Bruce, > > We went with two different Linksys dual-band adapters, one PCMCIA and > one USB.
