Buggy wifi in Manjaro KDE

Hello guys,

To be honest, it is my first question here.
I’ve tried to solve the problem by myself, but I wasn’t enough for it.

I have an Asus X571gt with Manjaro KDE installed on it. At my workplace, I am not allowed to use the wifi on my home laptop, and having no better idea, I shared the internet via cable through my phone. After this brilliant idea, the wifi in my laptop became a “zombie”: it randomly dies, and after a restart, sometimes it resets and works, and sometimes remains the same. Absolutely random if I have wireless network or not.
I’ve tried to make it work with systemctl and networkctl, tried to reinstall, but neither did help.

What should I try, why the wifi card dies all the time? I did not have this kind of issue when I used W*ndows.

Thank you for your answers!

Hi @S0R0S, and welcome!

In order for us, or anyone for that matter, to be able to provide assistance, more information is necessary. To that end, please see:

Hope you manage!


Tip:

To provide terminal output, copy the text you wish to share, and paste it here, surrounded by three (3) backticks, a.k.a grave accents. Like this:

```
pasted text
```

This will just cause it to be rendered like this:

Portaest sed
elementum
cursus nisl nisi
hendrerit ac quis
sit
adipiscing
tortor sit leo commodo.

Instead of like this:

Portaest sed elementum cursus nisl nisi hendrerit ac quis sit adipiscing tortor sit leo commodo.

Alternatively, paste the text you wish to format as terminal output, select all pasted text, and click the </> button on the taskbar. This will indent the whole pasted section with one TAB, causing it to render the same way as described above.

Thereby improving legibility and making it much easier for those trying to be of assistance.

Please edit your post accordingly.

Moderator edit: Formatting.

It’s `, not '. :wink:

Okay, I will use ` next time!

Do you know what could be the problem?
