[gentoo-user] wireless software config problem

[allan gottlieb]

My system runs gnome3/systemd.  I use NetworkManager, which is mostly
working fine.

At work the desired network is named "nyu".  The sysadmins say I need to
change at least one security parameter.  When I open the gui it shows
the network configuration parameters (by clicking the gear) and lets me
select different values.  However the "Apply" button never becomes
active so I can only "Cancel".

If I try to select the "nyu" network it asks for the password, which I
know and enter. I then click the appropriate button (something like
"apply" or "ok").  As expected the window goes away but I am not
connected and the window reappears.

A "tip" from the sys admins at work is to somehow tell my system to
forget all it knows about the network "nyu", but neither I nor they know
how to do it (they don't "fully support" linux).

Any help would be appreciated.

thanks,
allan
