I have been informed that the behavior below evidently is a bug
in NetworkManager. I am using NetworkManager Applet 0.6.4 under
RHEL 5, and NetworkManager and NetworkManagerDispatcher 0.6.5 .
NetworkManager did not offer me any choices in network, nor did it change from
the pre-existing channel 11 under the circumstances
below.
Is this a bug? If so, what is the fix?
I have now tried NetworkManager on the University 802.11g from my office. No
go.
Here is the output from scan (I wrote a small script to run the scan
and remind me that I needed to be root for the scan to work -- output
captured via script in a typescript file):

At home, using /usr/sbin/system-config-network-gui (that does the same thing as
manually editing the files, reloading, etc.), the WLAN is set to channel 11.
NetworkManager only showed one CSUSB WLAN, and refused to connect.
system-config-network-gui showed that the WNIC was still on channel 11. I
manually changed this via
system-config-network-gui to channel 1 (please see the scan above), and
everything worked, including NetworkManager. However, NetworkManager would not
automatically go to channel 1 nor would it allow me to choose channels.
Is this fixable via a NetworkManager post-build configuration file? Is this
fixable via a NetworkManager configuration file that is used during the build
process?
