Donna,
I am anything but a tech guy, but a while back Sandeep posted a video showing the difference of speed between hardwired and wireless set ups. After watching that video I hardwired my nurses laptop, and since then the delay in Imported Items vanished. My nurse was having up to 30 second delay of imported items till then. It is her workstation with her laptop that is used for the scansnap scanner. We use all windows 7 64 bit on all our computers. My main computer "server" and my nurses' hardwired and then I just use a laptop wireless with a gigabyte switch. So only have 3 machines in my setup.
