Hi. I have an R300 & R500 WAP installed at a site to stream audio. Both have the same SSID. Does anyone know how I can set them up so that the customers mobile devices will connect automatically to the WAP with the best signal? (Roaming?)
In addition, you can also increase the minimum communication rates the AP's will provide before they force a disconnect. This can be useful for "sticky" clients roaming between APs. It will push disconnects to them when the signal gets very low so they will connect to a better AP. The detriment is that your total area of coverage (the fringe) is reduced because you're not supporting the lowest communication rate allowed. This is commonly not a problem in office environments with awesome coverage where the wifi blows out the side of the 18th floor (you're not going to ever see the fringe 18 floors up 50 yards out).
However, my experience is that clients don't like to be kicked off a wireless network in this manner. If you are streaming video or making a VOIP / wifi call, it stops the video or drops the call, and the client may wait quite a while before attempting to reconnect to the network.
I wouldn't turn on SmartRoam for modern clients unless roaming is really really a problem.
