No Wi-Fi connection during and after installation

English Network/Internet

Hello,

First of all I must admit that I’m a beginner user. Secondly, as I mentioned in the title, I’ve got a huge problem with Wi-Fi configuration.

Here’s a screenshot of Network settings during installation process:

It’s a pity, because on KDE Live CD Tumbleweed version Wi-Fi worked flawlessly and openSUSE didn’t ask me how to configure internet.

What should I do to configure these devices properly? Please keep in mind, that I’m not familiar with hardware configuration.

Best regards,
Ron

Welcome to openSUSE Forums. Don’t worry, we were all Linux beginners once, and one never stops learning - it can be exciting and scary when starting out on the Linux journey. Anyway, that’s what the forums exist for - to share and help with all things openSUSE!

The first entry pertains to your wifi device, the second entry pertains to the wired ethernet NIC.

The first thing to know is that the YaST network config utility is good for those with fixed network environments, where the configuration is made once and does not change frequently. Otherwise, there is another way to manage your network configuration, and that is via NetworkManager (which includes a graphical front-end for configuration and network profile selection). This is typically used with laptops which need to connect to different network environments frequently. It is possible to switch from the first option (Wicked Serivce) to the second (NetworkManager Serivce), via the ‘Global Options’ tab in the Network settings utility. If using NetworkManager, the configuration is usually done via the graphical front-end running in your desktop.

This openSUSE guide is worth reading

BTW, do you know which desktop environment you are using?

Thank you very much for your warm welcome!

So I somehow managed to install openSUSE. I’ve configured Intel Centrino device with DHCP and WPA-PSK. I did it with trial and error method, but I’m not sure whether it’s correct?

After the installation, when I tried to open YaST2 Network Setting, I received a message: *“Warning, Network is currently handled by NetworkManager or completely disabled. YaST is unable to configure some options”. *So I opened Network Manager.

In “Connections” (aka Network Manager) there are many tabs. I’ve made a few screenshots, just to be sure that I didn’t mess things up.

Is everything ok (and secure of course)?

Currently I’m using KDE Plasma enviroment, which is just beautiful. I’m impressed how openSUSE work on my laptop (ThinkPad E330). Previously I was using Gnome 3 in Debian, but I was quite dissapointed how this distro worked (e.g RAM usage: about 1.3-1.5 GB compared to ~ 500 MB with openSUSE, slow boot time)

Thank you again for your help!

Well done! As you’ve now found if using NetworkManager to control your networking, the YaST networking utility is not required. It’s all done via the NM front-end. If you’re now connected, that’s all there is to it. NetworkManager can cope with multiple network environments, both wired and wireless. (Very convenient for users like myself working with different networks in the course of my work, and at home as well.

I’m a KDE Plasma 5 user as well. Enjoy the journey! :slight_smile:
