content: Like the previous reviewer, I am finding lots of incompabilities between vendors. My D-L 624 works just peachy with the built-in in my wife's Dell, and likes my Proxim Orinoco. It hates my son's Linksys when any form of encryption is enabled, but with WEP off handles it fairly well. For work I coupled the D-Link 624 with the 650 card and it works just fine. I had my son buy a Linksys card because the router that he's sharing at school is a Linksys, but which refused to recognize the Proxim card that works with my D-Link. I think all of this indicates just how imature this technology is. It probably ain't you if it doesn't work.Also, DLink does a pretty good job of updating their firmware, and you probably want to take the time to update the BIOS (easy, just follow the fairly clear instructions) before you start loading MACs and enabling things (you can't import your old settings after you flash the bios - you start over from the beginning).
