Q: WiFi Roaming Network Questions

With respect to WiFi roaming as show in the following article:  Wi-Fi base stations: Extending the range of your wireless network by adding additional Wi-Fi base stations - Apple Suppo…

 

The scenario is appealing since it uses the same SSID on multiple connected base stations allowing clients to move between wi-fi base stations without having to select a new wireless network.  However, in my testing, I have found that when multiple base stations are in range with the same SSID, the client is not choosing them necessarily based on signal strength.  I've had scenarios where the client stays with a base station when the signal strength is marginal at best even though it is next to another base station broadcasting the same SSID with a strong signal.  While the topology seems great, how do you configure an intelligent client that can select between multiple signals of the same SSID and pick based on signal strength?

 

thanks

    Macs will usually do a good job of automatically switching between access points when they detect a better quality signal from another wireless access point.

     

    But....iOS devices like the iPhone and iPad, and most other mobile devices, as well as most PCs will not do this very well, if at all. Nature of the beast, as their operating systems and antennas are just not that sophisticated

     

    If you move the iPhone from one area to another, you will need to get in the habit of temporarily turning off the WiFi as you move. When you are in the new area, wait a few seconds, then turn the WiFi back on the iPhone will usually find the new better signal.

     

    Bottom line.....the theory of a roaming network is nice, but unfortunately most connecting devices won't be able to take advantage of it without some help.
