If you're using a recent wpa_supplicant (1.0 or later), the supplicant's
'nl80211' driver, and a kernel wifi driver that supports nl80211, NM
0.9.2 and later should be using the background scanning functionality to
make the roaming experience a lot better.  In this configuration the
supplicant will trigger a scan whenever the connection with the
associated AP drops below a specific threshold, and it will also perform
an optimized background scan periodically.  So given all that, what
version of the supplicant, what version of NM, what kernel, what wifi
driver, etc?
