wifi driver not working

linuarchufan · 2024-09-09 18:12:04

Environment : arch kde
when i put my laptop to sleep and when i resume it then wifi whole module is gone. so i restarted it but still isnt fixed. I hard rebooted still no luck.
I can confirm that this is not hardware issue bcz its working on live boot

Ways i tried to fix it
- troublehsooting way : pressing power button for 20s when laptop is closed. while doing this step make sure all peripheral is disconnected too. then finally power on laptop normally
- if above didnt solve issue then simply install wifi driver from `yay -Ss rtw` . for mine it is `yay -S rtw88-dkms-git` so install that package and reboot and it would work.
- using modprobe way (reloading modules)
`lsmod | grep rtw` to get wifi module name
`sudo modinfo rtw88-8723de`
and
`sudo modprobe -r rtw88_8723de && sudo modprobe rtw88_8723de`

this is log in dmesg when i m trying to reload module

proof that no wifi module

update : when i installed other package called `rtw88-fixed-dkms.git` it messed up at something so now i cant even use wifi through live boot and windows. when i restart the module rtw88-8723de is gone through and i have to manually load it(though it still dont fix it)

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

Hey seth, Thanks for the response. Fast startup is already disabled and i have wayland. I have disabled sleep but problem is my wifi driver isnt working. What else I can do to fix it?

The screenshot indicating a taint means nothing, the kernel gets "tainted" because you're loading an out of tree driver, that's completely normal.

Please post your complete system journal for a boot covering a sleep and subsequent device loss, eg.

sudo journalctl -b -3 | curl -F 'file=@-' 0x0.st

for 3 boots ago
Or, assuming the deviceconstantly no longer shows up, the journal of the current boot ("… -b | curl …", no offset)

Also

rfkill
lsusb
lspci -k
ip a

Edit: please don't post screenshots, post the text.
If you don't have any internet connection, simply redirect the journal into a file instead of curl and likewise the outputs of the other commands - then usb-walk that to a system w/ network support.
Maybe https://wiki.archlinux.org/title/Tethering helps you.
