Let me start off by saying that I am HUMILIATED to ask this as I am VERY computer savvy and am the neighborhood/work "go-to" guy for PC/Mac/iPhone/anything type stuff. I have been all Mac for about a year now so I am still learning. I currently have the LOUSY WRT160N Linksys router. I hate it. I am very confused about Extreme/Express base station... All the mess about music and portability is confusing to me. Does it serve as a fully functional router? Thanks.
