Any one got any pointers on improving the roaming between aps? In my situation it geld like my stations are hanging on a little too long to an AP and maybe they could encourage the station onto a AP that has stronger signal? Any thoughts? Feeling like a leave the defaults alone answer coming on! ;-)
The wifi client driver software determines when it roams between one device or another. That logic is usually specfic to the manufacturer of the card or driver software. The behavior can also change between driver software versions, depending. It usually uses a range of metrics like signal strength, signal quality, how low the signal has to be when it roams, etc.
The local-probe-response-threshold paramater in the SSID profile can change roaming behavior, but it does not completely eliminate individual client behavior. Clients that are already aggressive become more aggressive and you might not want that, so it is important to determine if the issue is more on the client side, infrastructure side or if you have an issue, at all.
Putting access points on two different floors directly over one another instead of staggering them can make a client prefer an access point on the floor above, rather than one that is on the same floor. The Validated Reference Design on Roaming goes into great detail about all the arguments surounding mobile devices and how to optimize for them. I would just be cutting and pasting from that document into my answer....
The big question is, do you have an issue and it is worth changing the roaming behavior of all your clients for it..
