Wifi won't connect on CachyOS

Hey, I’m new to CachyOS, but there’s this problem I have.

I followed this tutorial about installing CachyOS pretty good this far, but the problem I always had was that my Wi-Fi won’t connect. It always say “Connection (wifi name) deactivated”, but to continue on, I used my android smartphone to connect to my PC with my wire, used tethering, and managed to complete the other steps before figuring out the wifi issue later, but that later is now, and I would prefer to use the wifi normally without needing my smartphone’s tethering. Unfortunately, I haven’t found much YouTube tutorial videos about fixing the wifi issue, at least not some that I could understand (Yep, I’m dumb. :joy:).

What’s up? Send me your PC specifications and I’ll give you the corresponding solutions, or I’ll try to do it haha.

I kinda feel like youtube tutorials are 90% a uniquely terrible source of info for things like this and 10% good actually.

Videoe are great for showing visuals of how things look and for showing subtle things that are difficult to describe, but less so for deterministic computer troubleshooting (or setup, because the pace is always the presenter’s and going back to check for errors or oversights is a nightmare)

what is your hardware, what is the output of inxi -N and if you try and connect and then run journalctl -e is there anything about your network there?

Right now, I can tell you what my hardware is.

It is almost always a good idea to include a z when asking/sharing inxi .. especially any inxi that includes the networking group .. as that is going to do the filtering of identifiable info, ex;

inxi -Naz

Of course it is included in the normal;

sudo cachyos-bugreport.sh

I don’t think you need to reinstall CachyOS just yet. Since USB tethering from your phone works, that tells me your internet connection itself is fine, and the issue is most likely related to the Wi-Fi adapter or its driver.

Before changing anything major, please run the following commands and share the output:

lspci -nnk | grep -A3 -i network

If that doesn’t show anything Wi-Fi related:

lsusb

Then run:

ip link

nmcli device

And also:

rfkill list

I want to verify whether the Wi-Fi adapter is being detected correctly, which driver it’s using, and whether it’s being blocked by software or hardware.

If rfkill list shows:

Soft blocked: yes

or

Hard blocked: yes

try:

sudo rfkill unblock all

and reboot.

The “Connection (Wi-Fi name) deactivated” message is usually caused by one of the following:

Missing or incorrect driver.

Wi-Fi adapter with incomplete Linux support.

rfkill blocking the device.

WPA/WPA2/WPA3 authentication issues.

Power management conflicts affecting the adapter.

Once I see the output from those commands, I can identify the exact Wi-Fi chipset (Intel, Realtek, MediaTek, Qualcomm, etc.) and give you a much more accurate solution than blindly reinstalling the system.
