You don't force a scan. NetworkManager will periodically scan with a backoff algorithm; it will start at 20 seconds and back off to 2 minutes. APs are kept in the scan list for a maximum of 6 minutes before being culled. The problem is that wireless is hard, and sometimes cards/drivers miss beacons. Often they will not report all the APs that are known to be around at a given time. So NetworkManager takes a composite of the last few scans as the scan list. 0.6.x also combines APs with the same SSID in the UI. 0.7 splits them out at the NetworkManager layer, while the applet combines APs that are similar based on more than just SSID (SSID, security settings, band, channel). > Perhaps the question may be how many APs can be handled and then those > are turned into the SSID list (when more than one AP per SSID is found > as in the case of some of these SSIDs). Are any of the APs hidden? Dan _______________________________________________ NetworkManager-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/networkmanager-list
