# Then disable the aggressive roaming if need be i.e. if client stationary etc. (be careful if roaming required!):

sudo defaults write /Library/Preferences/com.apple.airport.opproam disabled -bool true
sudo defaults read /Library/Preferences/com.apple.airport.opproam
{
    deltaRSSI = 10;
    disabled = 1;
    useBonjour = 0;
    useBroadcastBSSID = 1;
}

# And/or change the delta RSSI (after re-enabling opportunistic roaming):

sudo defaults write /Library/Preferences/com.apple.airport.opproam disabled -bool false
sudo defaults write /Library/Preferences/com.apple.airport.opproam deltaRSSI -integer 15
sudo defaults read /Library/Preferences/com.apple.airport.opproam
