Connecting to wifi

ajatashatru · 2020-10-01 14:11:57

Greetings!
Trying to connect to wifi with SSID and passphrase. Created a config file for this router at /etc/wpa_supplicant/mywifirouter.conf
and added the folowing
ctrl_interface=DIR=/run/wpa_supplicant GROUP=wheel
update_config=1
Then I tried to connect via:
$sudo wpa_supplicant -B -i <wifi iface name goes here> -c /etc/wpa_supplucant/mywifirouter.conf

And I got errornl89211: kernel reports : Match already configired:
ctrl_iface exists and seems to be in use - cannot override it
There's a file /run/wpa_supplicant/<iface name>
---
Don't have internet on my laptop now. Can I delete this and run wpa_supplicant again? How to connect with SSID and passphrase? Don't have networkmanager/wifi-menu. Any tutorial for doing this?
Stay safe!
Thanks in advance.

I suspect you have a conflicting network service already running - perhaps even just another instance of wpa_supplicant. You can check with tools like ps / pstree.

Yes. /usr/bin/wpa_supplicant -u -s -O as root. Tried killing the process, didn't work. How should I stop this, so wifi iface is available? Thanks in advance.

What do you mean by "didn't work"? Did you fail to kill the process or did killing the process not yield the desired results?
Please post/upload a complete system journal (sudo journalctl -b), if there's no usable NIC on the problematic system, you can use https://wiki.archlinux.org/index.php/Tethering (assuming you're posting from some phone right now) or usb-walk it to an online device.

That comman is from the wpa_supplicant service. You can just stop that service:

# systemctl stop wpa_supplicant
