Re: [SOLVED] Network after update and reboot, not working

Check rfkill and please post your complete system journal (sudo journalctl -b  | curl -F 'f:1=<-' ix.io) and the outputs of "uname -a" and "pacman -Qs linux"

Re: [SOLVED] Network after update and reboot, not working

Kernel matches, device isn't rfkilled and the journal really has only those brcmfmac calls.
But you don't seem to have linux-firmware installed? (What matches the error, -2 is ENOENT)

Re: [SOLVED] Network after update and reboot, not working

You mean you can't fetch the package because you've no internet access?
Do you have a smartphone, https://wiki.archlinux.org/title/Tethering?
How are you online right now? You could download the package, usb-walk it onto the dead system and "pacman -U" it.

Re: [SOLVED] Network after update and reboot, not working

This journal doesn't have the chip at all - does it still show up in "lspci"?
You could try the LTS kernel.

Ceterum ceseo: do you have a parallel windows installation?

Re: [SOLVED] Network after update and reboot, not working

If you run an parallel windows, the 3rd link below is a mandatory read.
You install the lts kernel the way you installed the main kernel, it's just "linux-lts" (you can have both installed together and select them at your bootloader)

Re: [SOLVED] Network after update and reboot, not working

You're supposed to read the 3rd link below and deacitvate windows fast start (hibernation in disguise) because there's a huge chance that this is what causes the chip to be absent on linux…

Re: [SOLVED] Network after update and reboot, not working

good morning....

I have Win10 on a external USB SSD and boot from there... the internal ssd is only for arch....


is there a chance to build the kernel new ?

Re: [SOLVED] Network after update and reboot, not working

ook what we have:

- the device is still there and works under win 10 (externalSSD booting from BIOS)
- lspci --> the device is already here
- kernel modules are loaded
- rfkill doesn't show the device?

a "ip addr" doesn't show the device :-(

Re: [SOLVED] Network after update and reboot, not working

It does not matter where windows is installed. The problem is what its hibernation state does to the bios and the rest of the hardware.
Follow the 3rd link below and make sure windows fast-start is disabled and it's not hibernating otherwise. Then reboot windows and linux a couple of times (borderline voodo, once should™ be enough, but anecdotally, two rebbots can be required) and see whether the device shows up again.

Re: [SOLVED] Network after update and reboot, not working

Windows fast start, not explicit hibernation (hybrid sleep)
Windows does not really shut down by default - it just hibernates to create the illusion that it can boot really fast now.

Please read the link I've directed you towards about a dozen times now.

Re: [SOLVED] Network after update and reboot, not working

If it's now consistently up: yes.
Otherwise it might be a temperature problem (but that would not match the previous situation where it would always work w/ windows - and: this is a classical pattern for the hibernating windows…)
