Issues with connecting to Wifi at my Community College

Hi, I’m very new to Manjaro, and this is the first Linux distro I’ve really enjoyed, something weird is going on with how the wifi works though. I had no problems connecting to my work wifi and my home wifi, but the problem stemmed from my School’s wifi. I did a log of what was causing the issue when it first happened and tried to show it to one of the IT folks on site but they didn’t know anything about Arch and probably nothing about Linux. So I made an account here to ask for some help as a new guy.

heres the dump that I got when I put the “net” out for the issue.

[Aug22 08:30] audit: type=1111 audit(1661175036.035:100): pid=339 uid=0 auid=4294967295 ses=4294967295 msg='op=connection-add-activate pid=633 uid=1000 result=fail exe="/usr/bin/NetworkManager" hostname=? addr=? terminal=? res=failed'

Also I’ve seen a lot of stuff about issues with my particular Network Controller its an RTL8821CE

When I tried to connect it said something about “Does not support PSK but the setting requires it” My work uses PSK so I don’t think its an issue on my side, so I guess it could be a problem on the IT folk’s side, but then again I don’t know I’m pretty new to this stuff. :stuck_out_tongue:

I’d like to thank y’all for your time. Sorry for the rambly mess.

and for “mhwd-kernal -li”

The following kernels are installed in your system:
   * linux515

try it with a differen kernel - you should have anyway 2 kernels installed, one main, and one backup …
install the 5.10 via comand:
sudo mhwd-kernel -i linux510
or via gui:
open system settings/kernel

then edit grub conf to be shown a grub menu during boot:
kate /etc/default/grub
and edit this line to look like this:
GRUB_TIMEOUT_STYLE=menu - its on the 3 line
save it, and update grub with:
sudo update-grub
reboot and in advanced options select the 5.10 (not the fallback one, the normal one), and test wifi with it

Okay trying this, I’m not gonna be back to school until tomorrow. So I’ll see if this Kernel version works. What should I do if this doesn’t work?

if it doesnt work with the 5.10 kernel, try changing dns in system settings/connections under ipv4 section, try quad:

if it also doesnt work install dkms drivers:
create this file with this command:
kate /etc/modprobe.d/blacklist.conf
and inside it put these lines:
blacklist rtw88_8821ce
blacklist rtw_8821ce
save the file with
install headers:
pamac install linux515-headers linux510-headers
install driver:
pamac build rtl8821ce-dkms-git
reboot and test

I’m at school right now so I can test this, but the dkms drivers didn’t work.

I also couldn’t do the quad ipv4 thing. Problem is when I try to connect to the wifi it doesn’t actually save the info to the Network Manager. All it does is kick this to my “notifications” when I try to connect.

802-11-wireless-security key-mgmt: access point does not support psk but setting requires it

But never actually saves the actual network to my Manager. So I wouldn’t be able to do the Quad9 stuff.

I fear this might be a problem that I’d need to go to IT again and see if they can’t give the network info to me so I can manually put it in. Though I doubt they’d do that.

check these posts:

So I found out the issue was around the certificates from the IT guys. I tried the Public WiFi, I tried the Eduroam and finally on a whim after just going “Eh why not?” tried to connect to the Encrypted WiFi version and I actually got through. So that’s the answer to my problem at the moment. I appreciate your patience and work you’ve put towards this Brahma. Thanks for your time.

so if it works, you can remove the headers and the dkms drivers:

pamac remove linux515-headers linux510-headers rtl8821ce-dkms-git

then remove the config:
sudo rm /etc/modprobe.d/blacklist.conf
then reboot
