Opened the box today, plugged in my DSL cable into it, Plugged the provided cable into the computer, Plugged it into the power and voila! It works great and the range is excellent ( my usual experience with Linksys). Including going to the browser page and enabling Wireless security and setting up a router password the entire process took no more than 3 minutes. I use Macs so the included setup CD was of no use to me but given the ease of setup without it I really don't think it is needed for Mac users. Not sure about reliability yet but my past experience with Linksys products was good so I am quite happy.
