Wifi not showing up after install

veneristas · 2023-09-11 18:26:33

Hello!

Yes, I know, typical subject, and yes I followed the wiki. Worked fine during the installation, iwctl picked the wifi up, and when the installation was done, iwctl was gone and wpa_supplicant wouldn't pick up anything either.

Went on ubuntu, picked up the lspci stuff, no network card (or maybe it's in there but no clue what it is): https://pastebin.com/svfMQJSB

Also found that randomly on the internet: lshw -C network. Which does give me a driver name: rtw_8723du. Apparently that's an obsolute driver for a realtek wifi card, but seeing that it doesn't appear on the list from above, yeah... Bit lost there, I admit my defeat lol.

Thanks in advancce!

Make sure linux-firmware is installed first and foremost, then post

lsusb #in usbutils
sudo journalctl -b

Linux firmware is indeed installed

Bus 001 Device 004: ID 0bdc:03a6 Y Media Corp. USB Camera

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I've tried a few drivers I could find with that RealTek thingy, these two in particular:

https://github.com/lwfinger/rtl8723du
https://github.com/lwfinger/rtw88

Both [makefile:XXX:modules] error 2 when trying to "make" them.

That would be more interesting from the Arch system that fails. If you wanted to test these drivers, you'd rather use: https://aur.archlinux.org/packages/rtw88-dkms-git read up on the AUR: https://wiki.archlinux.org/title/Arch_User_Repository

Sorry, here you go: https://pastebin.com/ng7Zhk1S

https://aur.archlinux.org/packages/rtl8723du-dkms-git
Or try the non-lts kernel for rtw88 support of the device.

Just the snake that bites its tail; it needs to grab something from a repo, so it needs internet.

I actually just ended up manually downloading that repo and putting it in that package. Ran makepkg -i. Went fine, but Module 8723du not found in directory /lib/modules/6.1.52-1-lts.

Installing that package hardly does anything but putting some source code onto your disk.

nb. that you'll need the linux-lts-headers package as well.

Can you tell me what wifi daemon ur using
example: networkmanager (i forgot the rest)

seth · 2023-09-13 04:06:48

The OP posted a journal, it shows that they're using NM and dhcpcd (which is a secondary problem) but the immediate problem is that nothing drives the WiFi chip
Mostly (likely) because they're running the LTS kernel and rtw88 doesn't pick up the chip and now they're trying to get the chip to work w/ the 8723du module.

chrooted back into the whole thing, got linux-lts-headers. I'm guessing that some sort of conflict happened because I already had some linux-headers installed, and well... It all went downhill lol.

I used to be able to start iwd nicely (with sudo systemctl start iwd), but once I got linux-lts-headers, pretty much everything broke. Iwd wouldn't start (and pretty much spamming of error I'm guessing), and even poweroff would fail.

I think I'll just leave it here and chroot back into the whole thing whenever I need a package from now on. Thanks for the help though.

No, you can and must have the header packages for all installed kernels installed. They don't conflict.

No. Just having some headers on your disk doesn't do anything.

OOORRR: we just fix this.
Post a current system journal (and ideally the iwd errors) so we can see where we're at.
