Enhancing a Wired LAN by Adding a WiFi Router To Create a Second Subnet
WiFi Routers cost less than Wireless Access Points. That may seem a bit odd, because it's obvious that a Wireless Access Point is a fundamentally simpler device; after all, every WiFi Router must contain a Wireless Access Point in addition to its Router and Ethernet Switch logic. The lower price seems to be a result of increased competition among vendors rather than functionality: Every major WiFi vendor makes WiFi Routers, but only a few make WiFi Access Points.
As we explained on the previous page, it's possible to use a WiFi Router as a simple Wireless Access Point, by bypassing the router section.
However, that's not entirely necessary. It's probably more common for users to simply "daisy chain" a WiFi Router directly into their wired LAN. In the beginning, this is an easier way to add WiFi functionality to your wired LAN setup, but it will create a second IP Subnet, which can complicate your life a bit. The video clips below detail this situation. If you have a wired router AND a WiFi Router in your LAN, you should watch all of these clips. Start with the first, and proceed to the last. (You should probably also watch all of the clips on the previous page if you haven't done that already.)
