NetworkManager / Wireless On Latest CentOS7 Installs

Hello All,

on the latest installs I’ve done, on 2 different types of Latitude laptops, with 3 different wireless cars, of CentOS7 and Mate desktop, it looks to me like NetworkManager is nog managing wireless. When clicking the nm icon in the top right corner, I’m not seeing access points.

Wifi seems enabled

[root@localhost ~]# nmcli g STATE CONNECTIVITY WIFI-HW WIFI WWAN-HW WWAN
connected full enabled enabled enabled enabled

but unmanaged
[root@localhost ~]# nmcli d DEVICE TYPE STATE CONNECTION
enp0s25 ethernet connected enp0s25
lo loopback unmanaged

    Dumb question: on my old Latitude, I have to make sure wireless is turned on with the little on the right side of the laptop. (When I bring it into work for conformation conformance, they turn it off, since they plug it in….)

    Hello Mark & Fred,

    thanks for the reply’s.

    See the last part of the my mail:

    The only difference I can think of, is that I now installed from CentOS7.1 minimal install media, and before from CentOS7 DVD. But there I also select minimal install.

    And then I sent another mail saying:

    and that is indeed the case.

    When installing from CentOS7 DVD, I end up with wireless managed by NetworkManager When I install form the more recent 7.1 minimal install media ( not sure of the exact name ) I end up with wireless not managed by NetworkManager.

    Further, for as long as I can remember, I always try to get rid of gnome keyring by renaming:

    mv /usr/bin/gnome-keyring /usr/bin/gnome-keyring.bak mv /usr/bin/gnome-keyring-3 /usr/bin/gnome-keyring-3.bak mv /usr/bin/gnome-keyring-daemon /usr/bin/gnome-keyring-daemon.bak

    but now this is preventing me from connecting to wireless networks.

    Greetings, Johan

    Hello All,

    this problem got bigger for me, and I could realy use some help. I now installed from a CentOS-7-x86_64-DVD-1503-01.iso, selecting minimal install in Anaconda. After the install, the wireless interface shows up unmanaged by NetworkManager.

    Before, I thought this could be due to using the minimal install media.

    [root@localhost ~]# nmcli d DEVICE TYPE STATE CONNECTION
    p4p1 ethernet connected p4p1
    lo loopback unmanaged —
    wlp1s0 wifi unmanaged —

    After installing the same way in CentOS7, the wireless card is automaticaly managed by NetworkManager as far as I
    can tell.

    lspci shows the right kernel module so this is not a driver issue. I use the same wifi cards in all the machines.

    I’m sure there are ways to make this work without NetworkManager, but I would like to have my users just click on the nm icon and select a wireless network.

    Can anyone shed some light on this?

    Many thanks. Johan

    No problem

    Check the other sub packages that got split like Bluetooth and wwan

    If you have mobile users that make use of certain dongles or tethering you may want to include these as well.
