Thanks Jirka, I used the command "nmcli -f all con list" to list all the saved connections. I used nm-applet to connect to network A and then to network B. I get the following.
NAME UUID TYPE TIMESTAMP TIMESTAMP-REAL AUTOCONNECT READONLY DBUS-PATH Auto A d***2 802-11-wireless 1291058354 Mon 29 Nov 2010 11:19:14 AM PST yes no /org/freedesktop/NetworkManagerSettings/0 Auto B 3***9 802-11-wireless 1291058380 Mon 29 Nov 2010 11:19:40 AM PST yes no /org/freedesktop/NetworkManagerSettings/1 The next time I restart nm-applet it automatically reconnects to network A and not to network B eventhough network B has latest timestamp. At first I though it was issue with my application, but nm-applet also behaves the same way. Is this a known issue?
