After recently getting a second wireless access point, I was finally able to set up my preferred home network configuration. This topology consists of both an open access point and a closed (password-protected) access point. I wanted to have our network fileserver and PCs on a closed network, but I wanted to have an open access point to make it easier to connect smartphones and other network devices (printers, netflix device), as well as to allow guests to our home to connect to the network, and to serve as an emergency backup internet connection for neighbors.

It was easy to set up, and the only cost was for a second access point, which I was purchasing anyway because I needed gigabit ethernet between my PC and network fileserver.
