Query: Good idea, but...

I was really psyched to get a reasonably priced NAS system but have had quite a few problems with it on my home network. Main problem is speed. It is attached by ethernet cable to my linksys router, as well as one of my laptops (XP). Even from that PC, access to files on the EFG80 is quite slow. And it becomes basically unusable when I try to access files from other laptops that are on my wireless LAN. Which of course completely defeats the purpose of a network-attached storage system.Not sure what the problem is. I have two drives installed, with one drive mirroring the other. Maybe that's causing the unacceptable performance.
