WiFi stops working semi-randomly

yclept · July 10, 2023, 4:27am

For preface, this problem persisted through my install of Endeavour until I decided to get an Ethernet to USB adapter for my laptop. The issue goes like this, I start up the laptop, I am already connected to Wifi as I set it up to auto-connect. The wifi works from a range of 3-10 mins. Randomly, wlan0’s status is set to DOWN and DORMANT and when I try to start it again using sudo ip link set wlan0 up it gives me the error RTNETLINK answers: Connection timed out.

The problem persists even after; turning off sleep mode, rebooting, and adding rules to my modprobe.

Here are the results of dmesg

Here is my ip link

If someone could help me out, you’d be a lifesaver, also let me know it i need to my topic to kernal and hardware.

What does this show

inxi -Na

yclept · July 10, 2023, 10:05pm

This is what it shows

Network:

ricklinux · July 10, 2023, 10:15pm

I guess you could try the git version rtw89-dkms-git
Not sure if you installed any package or it’s running on a kernel module?

yclept · July 10, 2023, 10:39pm

It was running on kernal module. I installed what you gave me but it still does not work even after reloading using modprobe. Interestingly when I was reloading the driver I got this error,

thomas@thomas-laptop ~/rtw89-dkms-git (master)> sudo modprobe -rv rtw_8852be
thomas@thomas-laptop ~/rtw89-dkms-git (master)> sudo modprobe -v rtw_8852be
insmod /lib/modules/6.4.2-arch1-1/updates/dkms/rtw_8852be.ko.zst 
modprobe: ERROR: could not insert 'rtw_8852be': Device or resource busy

Not sure if this is helpful but its something

yclept · July 10, 2023, 10:44pm

Ok so I rebooted the system, now wlan0 doesn’t show up at all. Im going to check the internet on how to solve this but just thought I’d update.

ricklinux · July 10, 2023, 10:48pm

Try removing the package then and hopefully it comes back on boot.

Edit: This is the other package recommended for that chip.

Edit2: As far as i know the 8852 should work out of the box on these newer kernels.

yclept · July 10, 2023, 11:01pm

Yeah uninstalling and reinstalling didnt work, now my wlan0 doesnt even show up on anything. inxi -Na just shows No PCI device data found. Im going to reboot again without my ethernet plugged in just incase its getting confused.

ricklinux · July 10, 2023, 11:03pm

Didn’t you just leave the git package uninstalled and then reboot?

yclept · July 10, 2023, 11:04pm

Yes I did that, it still didn’t show up

ricklinux · July 10, 2023, 11:06pm

Did you try using modprobe rtw_8852be

yclept · July 10, 2023, 11:09pm

Just tried it, it gave me this message in my dmesg

ricklinux · July 10, 2023, 11:11pm

The only thing i know is this is a newer WiFi 6 chip

ricklinux · July 10, 2023, 11:16pm

Did you try

sudo modprobe -r rtw_8852be

sudo modprobe rtw_8852be

yclept · July 10, 2023, 11:19pm

Yes, the device still isnt found

ricklinux · July 10, 2023, 11:20pm

Darn , sorry i got you messed up worse than it was.

yclept · July 10, 2023, 11:21pm

Don’t worry about it man lol, this is a clean install im not super attached to it. Plus atleast you could help

ricklinux · July 10, 2023, 11:24pm

According to this post #6 the dkms package should work.

yclept · July 10, 2023, 11:31pm

Still not working, I think I’ll reinstall so I can be back at square one. Be back in ab 20-30 mins.

yclept · July 11, 2023, 12:00am

Alright im reinstalled, this time in the cinnamon enviroment. The issue is still that I am able to connect and use wifi when I boot, but after a minute or so the wireless wifi turns itself off and im forced to use ethernet or to reboot.

Edit: Im going to see if I can open my laptop up to see if the Wifi module is intact and not burnt out as this might also be a possibility
