Networking – D-Link router WiFi and LAN segment

There's some good suggestions here: How can I get the same SSID for multiple access points? Personally, I use three routers with a hard-wired backbone, all with different SSIDs and passphrases and on non-overlapping channels. Only the router connected to the internet is used for DHCP though. It's a more complicated setup but it works for me.

            | Wifi |
