[SOLVED] Can't initialise wpa_supplicant (wifi) during boot

dongon104 · 2019-07-15 11:24:13

I usually run the following code after booting to initialise wpa_supplicant and connect to my saved wifi in the .conf file.

 wpa_supplicant -i wlo1 -c /etc/wpa_supplicant/wpa_supplicant.conf -B

I searched for some way to do this in the startup. I already enabled wpa_supplicant.service using systemctl but still its not even showing up in my pgrep output upon boot.
Please someone suggest a solution ?

Edited : I solved the problem. Thanks for everyone's contribution in guiding me to this solution.
Just rename and change path of the .conf file created as /etc/wpa_supplicant/wpa_supplicant-wlo1.conf. Then enable wpa_supplicant@wlo1.service. The service will identify the configuration file without us specifying. (try reading /usr/lib/systemd/system/wpa_supplicant@.service).

 mv ".conf file path"  /etc/wpa_supplicant/wpa_supplicant-wlo1.conf
 systemctl enable wpa_supplicant@wlo1.service

Post the status of the service you've enabled

systemctl status wpa_supplicant.service
systemctl list-unit-files --state=enabled
journalctl -b -u wpa_supplicant

Thanks V1del. This is the output.

I'm not sure whether wpa_supplicant.service will work for you, you should use wpa_supplicant@.service, or - better yet in my opinion, enable the wpa_supplicant hook for dhcpcd as you have that enabled already.

Thanks Trilby. But I had already tried enabling wpa_supplicant@wlo1.service but its not working.

>> systemctl enable wpa_supplicant@wlo1.service

Failed to enable unit: File /etc/systemd/system/multi-user.target.wants/wpa_supplicant@wlo1.service already exists and is a symlink to /etc/systemd/system/wpa_supplicant@wlo1.service.

There's no file such as wpa_supplicant@wlo1.sevice in /etc/systemd/system presently, although I did make one and deleted it while following some forum that didn't solve the problem.

The status report is :

>> systemctl status wpa_supplicant@wlo1.service

And I am sorry to say this, but I have no idea what a hook is or what I should do.

There should not be a wpa_supplicant@wlo.service file, that's not how the @.services work. But the @.service clearly failed due to not having an associated config file. I suspect the regular service failed due to it not being provided the correct interface name.
