[SOLVED] No wifi in Q4OS Plasma

naranja · 2023-11-01 20:16

Hi.
I just installed Q4OS Plasma in hp ProBook4310s in fifth laptop, and it doesn't have wifi, the system says error. But I accidentally deleted the wifi section looking for a way to connect to wifi. I can only connect to the internet via cable.

1. How to get the wifi module back in "System Preferences".
2. How I have wifi.

Help me please, thank you in advance.

PD: Attached image.

There are 3-4 buttons above the "Reinitiar" button, but they are barely visible with your dark theme. Among them there is a "+" button to add a connexion; there you can choose to add a WiFi connexion.
I also notice there is an exclamation mark on the network icon in the tray...
Is your WiFi enabled? What is the output of

$ sudo rfkill

Hi HChiper.
Thank you to try to help me. It tells me that the wifi is disconnected, but the wifi is on. By cable I have internet, not by wifi.

This is using the link of the another member that get the same problem with me in the new thread above than mine:

The step with no info is because the screen doesn't show me wifi ESSD.

It seems your WiFi is set off ("blocked') by a hardware ("HARD") switch. Is there a (small) switch somewhere on (the side of) your laptop? Or maybe disabled in the BIOS?

Thank you very mucho Hchiper. I get wifi now but it was on, only I turned off and on and it appeared the ESSIDs and I wrote the password. Thank you very much.
