    Default wifi connection how to?

    I have OpenSUSE Leap 15.1 installed on my PC. I would like to use my wifi network. I tried to use YAST2 but could not achieve internet access. Then I found a tip on the net to use Network Manager. Where do I find it and how to use it?

    What Desktop Environment are you using? You should have an applet in the desktop to manage network connections, that is an interface to NetworkManager.
    Should you prefer a text interface, open a terminal and try:
    Code:
    nmtui
    Check "man nmtui" for details. You might also check "man NetworkManager" or "man nmcli" for a command line interface.
    The following pages might also be useful (but maybe some content is not up to date):

    You may be suffering from a well-known bug in the Leap 15.1 ISO. It tells you that it is installing network manager and then installs wicked.

    Go to YaST>System>Network settings (ignore any error messages). Make sure the Network Setup Method is NetworkManager Service.

    Go to YaST>Servces Manager and make sure that NetworkManager is set to On boot and Wicked is set to Manually. Save any necessary changes.

    Close YaST; open a terminal, enter su followed by your root password and enter:
    Code:
    rm /etc/resolv.conf
    init 6
    When you reboot, all should be fine.

    The details of setting and using NetworkManager are here: <https://doc.opensuse.org/documentati...ce/cha-nm.html>.
    As far as openSUSE is concerned, there is some basic information regarding NetworkManager here: <https://doc.opensuse.org/documentati...sec-network-nm>.

    If your Desktop is GNOME then, the information which references the above Reference manual entry is here: <https://doc.opensuse.org/documentati...se-connections>.
    Once again for GNOME, the information regarding the “Password Wallet” «a “Key-Ring”» you'll need to store the WLAN “secrets” is here: <https://doc.opensuse.org/documentati...prefs-keyrings>.

    If your Desktop is KDE Plasma then, the information mentioned above is also relevant for the NetworkManager Plasmoid.
    Information regarding that KDE Plasma Password Wallet is here: <https://docs.kde.org/stable5/en/kdeu...et5/index.html>.
    You'll need this information to automatically unlock the Wallet on login: <https://wiki.archlinux.org/index.php/KDE_Wallet>.
    This is also useful: <https://wiki.archlinux.org/index.php...i-Fi_passwords>.

    Thanks for all of you! I have somehow fiddled with Yast2 and eventually managed to get my wifi connection working. But here comes the rub, occasionally I lose my connection. I found that unplugging my tp-link usb wifi adapter and then replugging it solves the problem, it starts blinking and wifi works again. I have a dual boot PC (win7/OpenSUSE...) and this very rarely happens in windows but is almost regularly happening in Linux. It cannot be a simple contact problem as then it would also regularly happen in Windows. But as I said I only have this phenomenon in Linux. Do you have an explanation?

    I have tried once again to plug in the adapter and run lsusb and uname -a, for lsusb I got the same answer as before but this time also:

    Realtek Semiconductor Corp RTL 8188EUS 802.11n wireless Network Adapter ........... so it is now there

    uname -a: Linux linux-ticm 4.12.14-lp 151.27- default # 1 SMP Fri

    May 10 141:13:15 UTC 2019 (8

    The problem remains sometimes I get the wifi working and then the adapter blinks, at other times I have to unplug and replug the usb adapter to get the wireless connection. When the usb adapter blinks thewifi is on!

    This does not happen when the use the windows 7 boot on the SAME PC!!!!!
