WiFi Network Configuration Finalized

I'm finally satisfied with the WiFi network configuration that I started over two weeks ago.  I learned a few things from this exercise.  Multiple access points can interfere with each other and result in slower connections.  To reduce interference, where possible, use different wifi channels or lower the transmission power of the wifi antenna.

Roaming is smoother if you use a single SSID for all your access points.  Tomato firmware is very useful but saving settings is flaky.  Virtual access points are helpful in organizing access security.  You can now buy a USB WiFi adapter for much less than the cheapest WiFi router.  You can change the SSID for both the primary and virtual access points on a WiFi PLDT MyDSL.

I'm lucky with the WiFi routers I bought.  They all allow virtual access points.  Some of them have both repeater and WDS capability.  Others have at least WDS and a DNS proxy or very configurable DHCP server settings.  Onto my next project!
