Wifi suddenly stopped working

[debianuse121212]

Hello everyone, I am a very new user in debian and so far my experience using it has been a blast! until.. suddenly my wifi just stopped working. I am using the gnome desktop environment and usually the wifi icon is there but now it's gone. I have no idea what i did and what happened because there was no error, glitch or anything that I am aware of at the time. Now i am connecting my laptop to my wifi router via ethernet in hope of finding a solution. Thank you so much in advance.

Does it work if you load up a live ISO image?

Hello, Does your computer have a airplane mode? For example, on mine, "Fn + F6" will toggle airplane mode, turning off both WiFi and Bluetooth.

I don't know, i haven't tried yet. But when i was installing debian the wifi works fine and it did until now. I've been using debian for 2 weeks ish

Yes, it does. I'm using a lenovo ideapada 330 14 igm. I have tried enabling and disabling airplane mode but nothing happened

Load up a live ISO image to test for hardware failure.

Load up a live ISO image to test for hardware failure.

Okay. I've downloaded the debian live iso and booted on a live usb. Not surprisingly, it worked. I know it's not a hardware issue because it was working before. So, what's the next step?

[Head_on_a_Stick]

Check the journal.

[debianuse121212]

Check the journal.

What journal?

[Head_on_a_Stick]

The systemd journal. Use the `journalctl` command to read the entries or the gnome-logs package if you prefer a GUI.

[lospala]

on a terminal type

Code: Select all

sudo journalctl  -b  -p3

to see in red what error have been detected on boot
