It turned out that, as a client, I don't have to bother with roaming stuff, it simply works out of the box.
Roaming has 2 types:
1) based on the disconnection (beacon loss)
2) based on the RSSI
Is it really roaming doing background scanning and preauth #2 (or) a
connect and disconnect (assuming same ssid and security) #1?
Though, I have a couple of questions regarding this OOBX (new buzz word seen here and there for "out of the box experience" :) ).
- At which level the roaming is done? Is it at the WiFi kernel stack (cfg/mac 80211), at driver level, or at chipset/firmware level or a mix of them?
- Can I change my setup, so that I have control over the roaming?
- Is it a good idea to try to manage that myself from userspace?
wpa_supplicant (userspace) takes care of the roaming for you, i belive
it has support for both types #1 and #2 (along with background scan)
Some proprietary version which implement at driver/fw level, this
reduces the roam delay as it need not involve any context switches.
Thanks Krishna for your answer.

Chris
