I've several laptops and phones which seem to report the "same" RSSI levels by 
running "wpa_cli scan && wpa_cli scan_result" but in the end the wpa_s trusts 
the data coming from the wlan-driver.

To be honest this setting does not affect devices in which the wlan-driver is 
responsible for roaming as then wpa_s will not do bgscan with those (you will 
see wpa_s reporting "nl80211: Using driver-based roaming" then).

The main point is that the -45dBm is considered very good RSSI-value and we 
should not be scanning unnecessarily as scanning will block other operations. 
Can't say if -65dBm is the _correct_ value but it's better than -45dBm.

Pasi
