Hello, After install Garuda and restart him system notification show me notification that cannot configure wlp2s0 and I can't connect with my Wi-Fi. I try dr46agonized Garuda and KDE Plasma, that problem is on both Garuda's. In the pictures below I show that notification and logs from systemctl NetworkManager. My network card is Qualcomm Atheros QCA9377
How can I fix this problem?
logout then login see if you can connect to wifi
I try 10 times. Unfortunately, it's still the same. Once connect, but if I restart this error still appears
Try running this command in the terminal:
bash -c "nmcli networking off; sudo systemctl stop NetworkManager; sudo ip link set wlp2s0 down; sudo rmmod -vf ath10k_pci; sudo rmmod -vf ath10k_core; sleep 5; sudo modprobe -v ath10k_core; sudo modprobe -v ath10k_pci; sudo ip link set wlp2s0 up; sudo systemctl start NetworkManager; nmcli networking on"
See if that improves things. Please post the output of those commands as text.
If that does not help then I would try one of the live ISO's that use connman instead of network manager to narrow the issue down somewhat. Try LX QT-Kwin from a live boot environment and report if you can connect properly using connman as a troubleshooting measure.
I quite like the LX QT-Kwin edition. If it works properly for you then you might even want to install that version (especially if your hardware is low spec).
It also would be nice to know the following output (as text not pics):
inxi -SMa; hwinfo --netcard --bluetooth | grep -Ei "(hotplug|speed|model|status|cmd|file|detected|driver:)" | grep -v "Config S"
Welcome to the forum.
Ok. This commands I execute on dr46agonized Garuda.
First thing I do is execute systemctl NetworkManager log:

Now I didn't try LX QT-Kwin. If I try I write that is the problem is solved.
Well the problem will be solved if you like LXQT and want to install it. Lxqt is rather minimalist and is more suitable for older hardware. As your hardware is not that old that may not be a desktop that intests you.
If it works on Lxqt it tells us through a process of elimination which networking components are more likely to be causing your issue. It is more of a troubleshooting step than a solution. However, I guess if you like Lxqt and don't mind installing and using that desktop then your problem would be solved as far as your networking issue goes. 
Please post:
rfkill list
lsmod | sort
I just checked the LX QT-Kwin, unfortunately the problem with this version is the same. Only after installation I could log into my Wi-Fi network, after rebooting I couldn't.
Below I place a window from connman, after rebooting.
After the first reboot I had a bug, unfortunately I don't have it saved, but something was related to the bus, I solved it by systemctl enable connman. Unfortunately, with subsequent reboots you still can't see the network.
To execute rfkill list lsmod | sort I must recover dr46agonized Garuda
I'm surprised because I tried Manjaro and Endeavouros, which are also archives and there the internet worked for me without any problems, so this is rather a software problem.
Before restoring the dr46agonized, I will save systemctl status connman from LX QT-Kwin with rfkill list and lsmod | sort.
I post rfkill list lsmod | sort from dr46agonized

Now if I restore Garuda from my backup my computer connect with Wi-Fi 4 or 5 times in row, but after next reboot problem still appear. I don't know what is this. Maybe sequence of run services.
Are you sure you haven't set restrictions in your router as to which IP addresses (or ranges) or MAC addresses are permitted on your network. This seems doubtful from the intermittent nature of your problem.
Just to be sure I'd check that you have the most recent firmware installed for your router. I would also consider resetting your router to the factory default configuration. Also, be sure you reboot your router whenever you have connectivity issues.
Another thing you might want to test is that MAC Address randomization is disabled. It is simply a matter of creating a configuration file to do this.
See:
Be sure to reboot your computer and your router after creating the required conf file.
Another thing you could test is in Network managers wifi properties try setting a "static IP address" for your connection. This sometimes helps.
Once you have MAC Address randomization disabled in Network Manager you could also try setting your device to be whitelisted in your router via its MAC Address. This is usually called "MAC Address association" or some similar term in your routers configuration.
You could also test disabling your routers wifi security feature very briefly to see if you can connect properly with it disabled. Be sure to reboot the router after making this change. Never leave your wifi network unprotected for any length of time, this is simply a very short term trouble shooting measure.
Please do not disregard these suggestions because Windows or some other distro works properly with your router. It can still be your router settings affecting this issue because Garuda's networking components may be configured in a different manner than others.
Garuda tends to use more cutting edge network components than other distros which could be causing your issue.
This may take a while to work through the possibilities of what may be causing this. I will need more outputs (which I will post later).
Record all the changes you make and report in detail on the results please.
I try to turn off MAC randomization and this didn't help. Once I connect with Wi-Fi and when I check status of connection I have "no connection". When I disconnect with my router I have checked syatus of NetworkManager and it shows me:

I don't think so it is something with my router. I think is a software problem, because when I try to connect after some hours I can connect with Wi-Fi and I have the internet, but if I reset I don't have and show me some problems when I try to check status of NetworkManager. I think the NetworkManager can't hold stable connection with the router.
systemctl status NetworkManager can show me

I have checked last status of NetworkManager after that when it try long connect to WiFi, and show me system notification that wlp2s0 couldn't be configured.
you can try disabling autologin
i think your issue is related to it
I don't think so, I can't connect with WiFi. I don't have problems with popup to write my password.
Edit: I have disable autologin by default I installed
I try tethering and the internet is working, but I haven't always could connect with internet by ethernet, so that is temporary solution
No offense, but your intuition isn’t really important here. If your networking knowledge and prowess was superior to others advising you then you wouldn’t need to ask for assistance.
Why bother asking for help if you simply are going to disregard the advice offered to you. I went to great lengths to write up steps that would be able to eliminate the router from the equation.
I asked you to try setting up a static IP address, did you?
Please confirm the extistance of the conf file to disable MAC Address randomization by using:
cat /path/to/conf/file
Again, your intuition is not that relevant here, working through the steps I ask you to perform in the correct order is the important thing. If it was a Network Manager specific issue then your connection would have been working correctly when you tested the Garuda version using Connman (replacement for NM).
You also did not reset the router to factory or test the router without authentication. If you have a replacement router you could swap in, then these steps could be skipped.
Testing a static IP is rather important as well as knowing your default name servers.
Please provide a written summation when you have performed the steps I have outlined previously.
Thank you.
I'm sorry, I didn't mean to attack you, I wanted to tell you what I think about it, because I'm afraid I could do something wrong and expose the computer and the network to danger from outside. I didn't mean anything wrong with it. I would prefer to test the software solutions first and then, if that doesn't help, then do some other steps to solve the problem.
First I installed again the latest version of Garuda Dr46agonized (from 05.12.2020) and then I set the static IP, at first everything worked, but after about 10 reboots back there was a problem with connecting to my network, but also as before there was no Wi-FI network, then I turned off the MAC address draw and after finding my Wi-Fi network it did not want to connect, and when the connection time was exceeded, suddenly all networks in my area were no longer visible.
I turned off the MAC address draw as follows:
[device]
wifi.scan-rand-mac-address=no
In which file location did you place those settings. That is not a command, but the contents of a configuration file.
Have you at least performed a reboot of your router?
A reset to the factory default settings on the router would be preferable.
Just because other machines are connecting properly through the router does not mean it can not be the router.
I have experienced situations where other machines were connecting normally through the router, but one Linux machine was not. Rebooting the router made no difference, but resetting it to the factory default fixed things up. That would not seem logical, but it happens.
Exactly the same way when I ask people to replace their Ethernet cable and they insist it can’t be the cable because it works fine in Windows. Seems logical, but that assumption is often wrong. Windows and Linux are not the same.
Please post:
cat /etc/resolv.conf
I format Garuda (I don't set static IP and set off MAC randomization) after reset my router to default settings. I think it helps me. I try about 10-15 times restart and shut down system and the result is 2 or 3 times show the problem with wlp2s0, but if I reset computer problem disappear, so it's much better than before, because before even reset did not help when there was a problem with wlp2s0. I must reset many times to show me networks, now all it takes is one reset or two. And then if I disconnect with my network I lost all networks in my surroundings, now it takes about 5 seconds and show me find networks. I'm curious to see how it will be in the future if this problem with networks will notoriously appear, or how it will be like now sporadic cases, and how it will be enough to reset the computer.
I had almost the same problem today (banging my head for finding the reason...). After an update... of course!
My wifi was successfully connected, but no DNS lookup was ever possible.
I was lucky I had found an old Arch bug report, which pointed me to the proper direction.
Long story short, it was solved (properly I suppose) enabling systemd-resolved.service
sudo systemctl enable --now systemd-resolved.service
I don't know why the update AI failed to fix this properly, as claimed by dev's answer in the bug report. But we still have a lot to add to our knowledge... @tbg
It seems also strange how I could successfully connect to DNS/internet before, since I find the same relevant error messages in previous boots.
