I am using the LinkSys router/ap/switch that you questioned about. It works great! I have two laptops (XP Pro/Mandrake and XP Home), both using linksys instant wireless PC cards, one desktop using a linksys wireless bridge, and one mandrake system wired connection. This in addition to my Z with a Netgear MA701 card. I also use the Z at work where it connects to an orinco or enterasys or something like that AP. I reccommend linksys products to people for home use. They support linux so I try to steer a few sales their way. I am pretty sure that the Z supports the linksys card you are looking at.
