Wifi not available working on booting manjaro. Multple restart needed

[priyank-mungra]

hello, I recently installed gnome manjaro (dual booted with windows 10 Home). At first I didn’t find any issues but after some days I required to reboot to get my wifi working. In current scenario I powered off and started again many times but what happens is initially my wifi gets connected to the router but gets disconnected after 30-40 secs. Then after it completely stops working. It is not able to find any nearby devices.

I have read some posts but none of them helped. Some were in very abstract manner for a noob person to understand.

below is the output of my “inxi -Fazy” command

Debian Manjaro does not exist. Debian is a distribution, Manjaro is a distribution (as Ubuntu is a distribution, Fedora is a distribution, and so on).

What you have installed is Manjaro GNOME, GNOME is the desktop environment.

Do you have some WIFI drivers available in Manajro Settings → Hardware ?

Also please EDIT your post, select all the terminal output you posted, and click the </> button, this is currently horrible to read.

[priyank-mungra]

There is no option like “Hardware” in manjaro settings as I am looking. But I guess I have hardware as it can be seen in output.
output of inxi -N
inxi -N 
Network:
Device-1: Realtek RTL8822BE 802.11a/b/g/n/ac WiFi adapter
driver: rtw_8822be

Yes I am changing it. Sorry for poor presentation.I am a newbie.

[omano]

OK now I can read it, thank.

Yes there is a Hardware section in Manjaro Settings. Maybe you’re not talking about the same tool (or GNOME doesn’t have this Manjaro tool)

I think my parents have the same WIFI controller on their computer, and it works with kernel 5.10 out of the box.

Do you think you can try this kernel? In Manjaro Settings → Kernel select Linux 5.10 and click INSTALL, then reboot, it should reboot on this kernel. If you want to reboot on the other installed kernel it should be simple to access the GRUB menu but for now, let see if it works good on kernel 5.10.

I don’t use GNOME so if what I’m talking about doesn’t exist for you, try to find where you change kernels in GNOME but I would be surprised this tool doesn’t exist in GNOME edition.

//EDIT: the tool I’m talking about, could be started from a terminal with manjaro-settings-manager

[priyank-mungra]

Ohhh there is another app “manjaro settings” I didn’t knew that only.
So there is hardware option. I am attaching its SS.

[priyank-mungra]

Should I install these drivers and try again?
Auto install Proprietary Driver & Auto install Open source driver?

this ^

and this ^

[priyank-mungra]

No i guess there is no WIFI driver section there.

[priyank-mungra]

current installed kernel : 5.9.16-1
I am trying to install 5.10.18-1. It is taking a bit to download once it is completed I will inform here.

[priyank-mungra]

okay kernel 5.10.18-1 is installed and running but same problem occurred. My Wi-fi agained gets disconnected and cannot find any nearby devices.

[priyank-mungra]

also I want to say that kernel 5.11.1-1 is also available if you want me to install latest one.

[omano]

Nope 5.10 is good, other kernels will disappear as 5.9 for example which is already End Of Life and will be removed soon. Only LTS kernels should be used if you’re a noob as you said, don’t add too much layer of things to look after and maintain by yourself later on.

If YOU want to try go ahead, but I don’t think it is the solution for you.

[priyank-mungra]

Actually there is wifi driver. I was not understanding what to do. I got some driver under Manjaro settings->hardware configurations->Network controller

[omano]

Can you not crop application window and show it in its entirety? I see nothing relevant, at least can’t see what I need to see.

[priyank-mungra]

No I just want my system to be stable. Talking about LTS it is showing latest LTS as 5.4.100-1. no other newer version is shown as LTS.

[omano]

5.10 is LTS it is just not marked currently but it is LTS trust me. Also read my previous post.

[priyank-mungra]

Yes I trust you and I have updated the full screen picture of Manjaro Settings->hardware configurations->Network Controller

[omano]

So it doesn’t seem to me you have possibility of installing an alternative driver for this WIFI controller from here. What I would recommend is to get to the basics, and search the forum. Example search:

https://forum.manjaro.org/search?q=RTL8822BE

Read the various threads and see if a recent one has a solution to have it work.

On a side note about what you were talking about

@priyank-mungra

Should I install these drivers and try again?
Auto install Proprietary Driver & Auto install Open source driver?

I would right click the video-hybrid-intel-nvidia-prime driver and click INSTALL to have proper support for your dual GPU system, but this is another topic that I would recommend to open a new thread for if you need help about this. But this has nothing to do with your WIFI issue.

[priyank-mungra]

Thank you @omano for your help. I will try searching from the suggested link.

Also can you help me understand why the same wifi adapter works fine for windows but not for manjaro linux. I want to mention that it was working fine on ubuntu which I had previously installed before I tried manjaro.

[omano]

It’s a driver thing I guess, you need proper software to control the hardware properly, if the system has proper software built in, it will work properly, if it doesn’t have proper software built in, it will not work properly.

//EDIT this thread seem similar to your issue and his solution was kernel 5.11 Wifi misbehaving and this other thread has another solution RTL8822BE Wi-Fi not showing - #4 by Wollie. Try simple solution first, install kernel 5.11 and see. If it doesn’t work then try maybe the other one.
