Wireless is new to me. These two things initially appear to be the same thing, but the products advertised as access points don't mention the ability to hook up to a DSL or Cable Modem, nor do they advertise any kind of firewall capability. On the other hand, they don't seem to cost any less, either.
So what's the deal? Is there an actual difference, or is it just a matter of vendor preference in terms of naming and feature preference?
