it appears that restarting nm-applet solves the problem (at least, temporarily). this, however, has to be done from the shell prompt (killall nm-applet && nm-applet &) and cannot be done via the gui.

Specifically, when I click on the NM menu in the top menu bar (between bluetooth and sound volume), I see the usual items (wired network/disconnect/wireless network/disconnected/hot spot 1/hot spot 2/.../connecto to hidden/create new/vpn/enable/info/edit); and the list of the available wifi hot spots changes with time and they become (un)available. when I plug in a wired connection, I become connected to the internet and this is reflected in the menu too. however, nothing I do with the menu has any effect: I cannot disable/enable wireless/networking; I cannot select the hot spot to connect to &c &c &c. The only thing I can do it kill the NM process which is then auto- restarted. I tried reinstalling all the network-manager-* packages to no effect.
