Apparently, after talking to a good friend, you can use the BEF11S4 (I think, it's the wireless, 4 port switch, NAT, firewall, broadband router) as an access point from another of the same.

With them going for $99 on compusa.com, why get the WET11? Size? Lack of complexity? For less $$$ I could have a superior product with more flexibility.
