Unable to find any wifi connections

I have a Pinebook with Manjaro-ARM, KDE-Plasma desktop. I use it with a wireless router (PlusNet) . Yesterday I updated to 2020-08-25. All went well. However, today it seems unable to find any wifi connections. I am using a temporary wired connection at the moment. Of course, this may be a coincidence. My Raspbian Rpi4 connects by wifi, so the problem is not at the router end, though I have restarted the router just in case. Are there any commands with which I can test the wifi hardware in the Pinebook? Have patience, I am very much a beginner with Linux.

:+1: Welcome to Manjaro! :+1:

Please read this:


and post some more information so we can see what’s really going on. Now we know the symptom of the disease, but we need some more probing to know where the origin lies…

An inxi --admin --verbosity=7 --filter --no-host would be the minimum required information… (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)

:innocent:

I did: inxi --admin --verbosity=7 --filter --no-boot > Public/mydata
then copied and pasted Public/mydata into this post, only to get a warning saying I couldn’t post links. What links? What do I do now? Sorry, this is rather new to me.

Does the network applet simply not show any wireless networks?
Have you tried toggling the Wifi checkbox in the applet on/off again?

That’s because you tried to link to a file on your local hard disk (which we cannot access) so just:

  • open that file,
  • copy the text,
  • respond to this message
  • type 3 backticks: ```
  • paste the file contents
  • type 3 more backtick.
  • hit Reply

and then your inxi output will look like this:

Like this

All of the above is described in the article I originally linked to, so please help us help you!

:innocent:

@Strit. No wireless networks shown, despite fact that I am using it on a different machine right now. There is no wifi checkbox. I presume by ‘applet’ you mean whatever is putting the network icon on the taskbar?

No wifi checkbox…?

It should be there. What image did you install from?

And what’s the output of:
pacman -Qi ap6256-firmware

And does sudo systemctl restart NetworkManager bring it back?
(the command is case sensitive)

Sorry, forgot the backticks.

Ah, this is the original Pinebook.

What kernel are you on?

5.8.3-2-MANJARO-ARM aarch64

Hm. did you get any errors when updating? Like DKMS errors?

Try reinstalling the wifi driver with:
sudo pacman -S dkms-rtl8723cs

If that produces something that might look like errors, please post them.

The image was reinstalled on June 24 by the company, RComp, that I bought it from.
Currently the kernel is 5.8.3-2-MANJARO-ARM. It was working well until a few days ago.

Output from ‘pacman -Qi ap6256 -firmware’:
error: invalid option ‘-f’

Output from ‘sudo systemctl restart NetworkManager’:
Failed to restart NetworkManager.service: Unit Network.Manager .service not found.

That’s a huge issue. That service file should be there on all our Pinebook images.

If I was you, I would try:
sudo pacman -S dkms-rtl8723cs networkmanager

If any errors, please post them.

If successful, reboot and see if you have wifi.

(1/1) reinstalling dkms-rtl8723cs
Error! Could not find module source directory.

Okay.

Try this command instead:
sudo pacman-mirrors -f5 && sudo pacman -Syyu dkms-rtl8723cs networkmanager

Rebooted after reload of networkmanager but no change. No wireless access points shown. In configuring the Wi-Fi connection should the mode be

Access Point, Infrastructure or Ad-hoc?

Though I suspect that this is a superficial detail by comparison.

Strit, Jeg sku’ alligevel tilsaet mange tak for Deres tryllekunstlige svarer. Jeg gaetter at problemet stemmer fra hardware mere end software.

Does this mean we have to close this topic as “Hardware error”?

If not: You are connected through Ethernet while trying to solve the WiFi issue, right?

(Sorry! Just checking! Don’t kill the messenger! :scream: )

Yes. I have Raspbian on an Rpi4 that talks to my router by wifi, and a Pinebook with Manjaro-ARM that used to do that, but now can be connected by ethernet2usb cable. I use Chrome on the former, Firefox on the latter.
