[SOLVED] No WiFi. No WiFi devices in Connman.

_mAL_4_th3_fl00r · 2025-09-27 02:01:04

Two days ago I installed zsh and ohmyzsh. After all current configurations were done I ran:

apt-get autoclean; cmac; .z; apt-get dist-upgrade; apt-get upgrade; apt-get update; reset

Now:
No power to usb WiFi dongle (PAU0B AC600), yet it's ID'd in lsusb and was working prior.
Connman doesn't show it even existing.

Directions to getting WiFi back up are appreciated.

What does rfkill say?

_mAL_4_th3_fl00r · 2025-09-27 17:05:07

rfkill

outputs nothing.

Kinda hard to help, not knowing what version of Devuan you are using, compounded by the fact that this question has been posted in Derivatives instead of the apropos tech area, are you using Devuan or one of the derivatives? Daedalus, Excalibur or other version of Devuan?

Just off the top of my head, I see the Mediatek wifi device, and there have been some changes to where Mediatek firmware is located, previously it was part of firmware-misc-nonfree but in Excalbur (and Daedalus backports) it's been split off and is now in firmware-mediatek and the new package conflicts with older versions of firmware-misc-nonfree. So maybe something got removed or held back during your upgrade depending on what you have.

_mAL_4_th3_fl00r · 2025-09-27 21:19:56

Distro is Refracta 11(Chimaera). Please scroll down on the code text for system info(neofetch).

delgado · 2025-09-27 21:25:26

@_mAL_4_th3_fl00r #1 : beside that the commands are to execute from right to left ... what is "cmac; .z" doing?

_mAL_4_th3_fl00r · 2025-09-27 22:05:26

@delgado
alias cmac = 'macchanger -A eth0'
alias .z = 'source ~/zshrc'

ralph.ronnquist · 2025-09-28 06:52:20

Not sure it'll make a difference, but the normal sequence is:
to run "apt-get update" first, because that updates the local meta information to be current.
thereafter you run "apt-get upgrade" to bring existing packages up-to-date as much as possible.
finally you run "apt-get dist-upgrade" to also handle changing dependencies of new package versions, which may involve both removing and installing packages.

Does udev detect the device and install associated modules? What's in /sys/class/net/
What's in your latest boot dmesg?

My bad, sorry. Yeah, my guess is you're missing the mediatek firmware package I mentioned, the misc firmware package got updated and the new one no longer has the mediatek and ralink firmware in it that it used to have.

_mAL_4_th3_fl00r · 2025-09-28 17:22:39

@ralph.ronnquis
I've changed the apt-get sequence as proposed.

/sys/class/net only contains eth0 lo

Couple dmesg lines I noticed:

@greenjeans
You may be correct on the missing firmware.
/etc/Wireless/RT2860STA only contains only RT2860STA.dat

I tried adding RT2870STA.dat from https://github.com/pauledd/mt7610u then a reboot, to no avail. Not sure if I even did it right .

The firmware that is loaded by the kernel is located in /usr/lib/firmware/mediatek. Check what you got in there. The dat file is something else but firmware.

_mAL_4_th3_fl00r · 2025-09-28 19:53:10

@rolfie
The directory usr/lib/firmware does not exist on my system. Will creating it and adding https://github.com/pauledd/mt7610u suffice?

No need just install the proper package and it will be created with needed firmware put there.

zeus@9600k:~$ apt-file search mediatek/mt7610e.bin
firmware-mediatek: /usr/lib/firmware/mediatek/mt7610e.bin

You want the firmware-mediatek package.

Ok. Ran this manualinstall_wififix.sh and got WiFi back up. Thank you everyone.
