I would try this:

1. Select the system menu (top right corner)
2. Select settings (lower left corner of the menu)
3. Select Network
4. Click the gears icon for the wireless network
5. Select the "Reset" option (last option available)
6. Click the "Forget" button

This should allow you to start from the beginning. You should not need to
muck around  around with permissions, it should Just Work™.

I run gentoo stable and networkmanager-1.4.4-r1 doesn't have a policykit
use flag (version ~1.8.0 does have a that use flag).

I will try changing the settings tomorrow as root (the network in
question is at work)

This sounds like an OS user permissions problem.  Do you have sys-auth/polkit 
installed and is USE="policykit" enabled for networkmanager?

Also have a read here in case you need to create this rule:

I must not have been clear.  They told me about peap etc.
I can't make network manager change to the desired configuration.
When I change the settings, the gui doesn't let me apply the change.

I interpreted the slow zeroing as a performance decrease. If you can
benchmark to check you may want to.

If that situation doesn't correspond to a general decrease in performance I
will be very surprised.

Typically a closed source Windows program which may bundle the firmware in
it.

Your sysadmins are talking shit. What they need to do is tell you what
the security settings are for that SSID. If it's a corporate firm it's
likely something along the lines of "Protected EAP (PEAP)" and they must
tell you what it requires. Or, find a working Windows machine and check
it's wireless network property for that SSID. Usually, one can figure it
out relatively easily.

That your sysadmins don't know this is a rather brutal indictement of
your sysadmins...

In connman one often has delete and re-create connections as it often
happens there isn't an Edit button in connman applets! But not in
NetworkManager:
right click -> Config -> Edit -> Save
always does the trick if you click the right buttons in the Edit step

[gentoo-user] wireless software config problem

2017-09-06 Thread 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

I mentioned the same in an earlier post, but unfortunately it seems
Samsung's Magician software is required to do this (Windows application.)

I haven't noticed any degradation of performance, though I haven't run any 
tests.

Do you mean the firmware of the NVMe drive? How would I go about that? I 
don't see any mention of firmware on Samsung's site.
