[SOLVED] Wireless Not Showing in nm-applet

amhainen · 2024-09-07 15:43:48

Background: I couldn't get nm-applet to show/appear in the tray this morning. I reinstalled and then it started reappearing reliably in the tray.

Now I cannot find any listing or checkbox for my wireless networking in nm-applet. If I "Edit Connections", then I can see that the wireless hasn't been used in 2 months (I keep this laptop plugged in with a wired network connection). The laptop is dual-booted with Windows 10. The WiFi is working fine in Windows. The switch for the wireless adapter is "ON".

Any ideas how to get nm-applet to recognize or list the wireless? Thanks!

The laptop is dual-booted with Windows 10. The WiFi is working fine in Windows.

3rd link below. Mandatory.
Disable it (it's NOT the BIOS setting!) and reboot windows and linux twice for voodo reasons.

If that's not it, please post the outputs of

ip a
rfkill
lspci
sudo journalctl -b | curl -F 'file=@-' 0x0.st

(The last one uploads the system journal to 0x0.st and prints a link, you obviously need internet connection for that)

I stumbled on your post on nearly the same topic a year ago: https://bbs.archlinux.org/viewtopic.php?id=288547

When I checked "ip a", there was nothing regarding the WiFi...

I have a few different kernels installed. I was using "LTS" (old laptop, didn't think much of it) and that was where the issues were. I rebooted with the normal kernel (currently 6.10.8-arch1-1) and the WiFi was there and had no issues and I think showed up as "wlp3s0". Forgive me if I am explaining my kernel notes incorrectly.

Do you know if there should have been an issue with the LTS kernel?

Thank you for your help! Double thanks since your old post helped me!

You're probably relying on an OOT module (broacom? realtek?) and only have a prebuilt module for the main kernel installed or use a dkms module and don't have linux-lts-headers installed?
Or there's a bug in the LTS kernel module and the driver crashes - hard to tell from here
What's the output of

lspci -k

on the regular kernel?

Edit: emphasis based on the linked thread.

Wow! It's amazing how much you nailed in that last post.

I installed

sudo pacman -S linux-lts-headers

since it was not installed. Rebooted, selected the LTS kernel, and the WiFi was right there.

Just to try to be a better newbie, I Googled "linux headers" and see that the headers "ship separately". Why? I'm not sure I follow even after reading http://linuxmafia.com/faq/Kernel/usr-sr … mlink.html.

I only switched to EFI machines about five years ago. I started installing a bunch of kernels and learned you can fill up the /boot or /efi if you use the default recommended 500MB (or 128MB?) size. On this laptop, it's an older BIOS machine and I installed a bunch of kernels wihtout any size worries (LTS, Zen, RT, hardened, etc.). Do I need to install linux-headers for each of these? I'm assuming so based on this thread.

Thanks for helping me to learn!

Would you believe I have been using Linux since U***tu Breezy Badger in 2006? (And I still don't have a handle on these basics!).

I did check

find /boot/vmli*

and installed the headers for each kernel that was installed.

Lesson learned: install the headers for each kernel!

Size¹ - and they're completely pointelss for regular users unless (for the most part) you're using dkms (or otherwise want to build OOT modules) and even in that case you might not require/want them for every kernel installed (because eg. you already have a pre-built module)

¹ Otherwise arch gets accused of being bloated, https://bbs.archlinux.org/viewtopic.php?id=247863 - nice to see McBloatface is still up
