Wifi is making me nuts
Wifi is making me nuts
Forgive me if this has been beaten to death; I did do some digging, to no avail.
I know this ought to be easy, but I'm having trouble w/ wifi.
Specifically, getting NetworkManager-wifi working. Which should make getting wifi up and working easy.
First, release details (upgraded today). I'm using gnome.

Re: Wifi is making me nuts
I am using MATE and there is not much of a nice NetworkManager applet in sight.
But NetworkManager-tui works okay for me and looks clearer than the other options.
So,
And then
Activate a connection
Get a list of Wifi networks
Pick one, put password
There, you should be able to connect.
Just got that done this morning where I needed to connect my CentOS7.3 box, worked.
But NetworkManager-tui works okay for me and looks clearer than the other options.
So,

Re: Wifi is making me nuts
There is a package network-manager-applet-1.4.0-2.el7.x86_64 to provide the icon to allow configuration via the taskbar icon in a GUI. You can also use nmcli or nmtui from the command line.
The future appears to be RHEL or Debian. I think I'm going Debian.

Re: Wifi is making me nuts
OK, I just had an interesting hour.
nmtui? --it was already installed.
The installation of network-manager-applet.x86_64 0:1.4.0-2.el7? It gave me a little icon for *Ethernet* immediately after.
Huh. I figured the wifi icon might appear after a reboot.
The reboot made the Ethernet icon disappear, AND killed the port.
I fought with that a spell. I had a solid green light on the pci nic. Weird. Who fights with Ethernet cards anymore?
Tried a different cable and switchport. No difference.
I was losing hope. ifconfig only showed lo0, and a damnable virbr0 port that doesn't appear in /etc/sysconfig/network-scripts. No p2p1. Anybody have a theory on why virbr0 persists? It has no ifcfg, and I have no config I'm aware of that would create/associate it. I'll google THAT later.

*phew*.
nmcli and nmtui see only virbr0. Maybe this is normal?
I'm not terribly versed in either utility, but they seem straightforward.
Why I even see virbr0 is curious.
And, no wifi still. I *assume* since lsusb sees the usb wifi fob that wifi should work? This fob worked under Mint on a different box.
Maybe Centos hates this usb fob.

Fallacious thinking?? I am fresh out of other spare usb fobs with which to try.
Anybody recommend a garden-variety usb fob Centos likes (I'm aware the chipset matters), easily available on amazon??

*phew*.
nmcli and nmtui see only virbr0. Maybe this is normal?
I'm not terribly versed in either utility, but they seem straightforward.
Why I even see virbr0 is curious.
And, no wifi still. I *assume* since lsusb sees the usb wifi fob that wifi should work? This fob worked under Mint on a different box.
Maybe Centos hates this usb fob.

Fallacious thinking?? I am fresh out of other spare usb fobs with which to try.
Anybody recommend a garden-variety usb fob Centos likes (I'm aware the chipset matters), easily available on amazon??

Re: Wifi is making me nuts
I made it work in MATE.
There is a parameter in /etc for the applet that is hiding it from the panel when it matches 'gnome'.
I guess that is because Gnome3 has another thing and MATE is Gnome2 but matches.
I will post the config once I have access to my box.
This is indeed a pain and I had to use nm tui for my wifi as well without the applet showing.

Re: Wifi is making me nuts
I 've done this over the cli, but it should be in the NetworkManager's applet (click and forget - aka Windows style).
What is the output of:
It should show something like this:
Hint: "bash-completion" is your first friend with 'nmcli'
What is the output of:
Code: Select all

Re: Wifi is making me nuts
SOLVED.
I am a meat popsicle. IT WAS THE DANG WIFI FOB.
I ponied up for a couple of wifi fobs off Amazon; the garden variety Panda 802.11n fired right up. A systemctl stop network.service and a start brought the wifi to life.
*thwack* --sound of head pounding against desk.
