I can't connect to internet

Hi.

I installed arch recently and I can't make my wiki network works..

I scan with wpa_cli and the output is CTRL-EVENT-NETWORK-NOT-FOUND

And scan_result gives no results.

I install this driver: https://aur.archlinux.org/packages/rtl8821ce-dkms-git/  from the aur that I guess is the correct one.
Thanks for your help

$ lspci -k

Re: I can't connect to internet

You'd need to provide that same information again as the general state of the HW is the same as in your earlier thread.

Re: I can't connect to internet

I know. But the problem is not the same. If I didn't post my system information someone would ask for it.

Re: I can't connect to internet

I mean: post your system journal.

But the problem is not the same.

Maybe, but the presented symptoms don't support that theory.

Re: I can't connect to internet

Here is the output of sudo journalctl -b

The main problem I think I have is that I cannot scan for wireless networks, I tried a lot of differens programs and no one could scan a network

Re: I can't connect to internet

The first and foremost problem is that you're trying to start a second wpa_supplicant service and the first one, invoked by networkmanager, is still running and NM is also scanning around.
So to get to a deterministic baseline, stop networkmanager and wpa_supplicant, then try a manual w/ wpa_supplicant or iwd alone.

Also post the output of

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

to ensure there're not other NIC controlling services lingering around.

Re: I can't connect to internet

I stopped the NetworkManager and scan with iw

$ iw dev device scan

But it couldn't find any network.

$ find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

Re: I can't connect to internet

I stopped the NetworkManager

Also the second wpa_supplicant service?

But it couldn't find any network.

Were there any error messages?

Please post a "clean" journal (ie. disable NM, reboot, scan, then dump the journal - then start NM - iirc there's a wired device you probably use to be online) and post the journal you previously dumped.
