Wifi broken, Network Manager interface and icon missing after 2009-09-24 update

[Rob Hamm]

Binary package hint: update-manager

After the Karmic update on Sep 24, 2009, wifi fails to connect, Network Manager icon is missing from panel, and clicking on Network Connections in the System >> Preferences menu does nothing at all. I have tried reinstalling network-manager-gnome to no avail. This problem occurs as both user and root. Ethernet works just fine.

Update: I just tried

$ network-admin

and got the following:

The program 'network-admin' is currently not installed. You can install it by typing:
sudo apt-get install gnome-network-admin

So I reinstalled, this time from the command line, as per instrsuctions, then tried to run again with this result:

(network-admin:2014): Liboobs-WARNING **: There was an unknown error communicating with the backends: Launch helper exited with unknown return code 0

(network-admin:2014): GLib-CRITICAL **: g_hash_table_lookup: assertion `hash_table != NULL' failed

Also, an error message appeared that said, "The configuration could not be loaded. An unknown error occurred.
