Unable to bring intel network interface up

Ubuntu server doesn't want to enable my wifi network interface: wlp0s12f0 on my laptop (Lenovo 300e 2nd gen): State DOWN

I tried ifup, iwconfig and ifconfig. I wanted to connect my laptop to wifi, but It doesn't seem to work, also when I try to scan for ESSID's (wifi networks) there are no results, Im very new to linux and this is my biggest problem yet.

I have acces to the internet via ethernet, but I want to use wifi. I also tried downloading the Intel drivers (Intel® Wireless-AC 9560) https://www.intel.com/content/www/us/en/support/articles/000005511/wireless.html and followed the instructions in the README file, but it doesn't seem to work. maybe I installed the firmware incorrectly?

Btw rfkill shows that everything is unblocked, for either hard and soft block.

I can’t even bring the interface up. And when I scan for nearby networks with iwlist the result is: ‘’’ interface doesn’t support scanning’’’. While I’ve used WiFi on that laptop before when I had windows on it (and it worked perfectly).

Any help would be appreciated! I'll try to follow the explanation as best as I can.

Edit: Bump.

I think the problem has to do with non-functioning drivers or firmware, But how do I know what software/firmware I need? Again, Any help would be appreciated!

Vă sugerez să editați fișierele netplan:

sudo nano /etc/netplan/00-installer-config-wifi.yaml 

Modificați fișierul la:

reţea:
  versiunea: 2
  redator: în rețea
  wifi-uri:
    wlp0s12f0:
      dhcp4: da
      puncte de acces:    
        "********":
          parola: "********"
    

Bineînțeles, menționați-vă detaliile exacte aici. Netplan este strict în ceea ce privește indentarea, spațierea etc., așa că verificați cu atenție de două ori.

Salvați (Ctrl+o) și ieșiți (Ctrl+x) din editorul de text nano.

Urmărește cu:

sudo netplan generate
se aplică sudo netplan  

Wireless-ul ar trebui să funcționeze acum, totuși, ar putea fi nevoie de o repornire.

Dacă doriți o adresă IP statică, vă rugăm să vedeți șablonul:

cat /usr/share/doc/netplan/examples/static.yaml

De asemenea, vă sugerez să modificați celălalt fișier pentru a citi:

reţea:
  ethernet:
    enx60a4b7714185:
      dhcp4: adevărat
      opțional: adevărat
  versiunea: 2 
  

Presupun că, odată ce wireless-ul funcționează, doar rar vei folosi ethernet-ul. Interfețele care nu sunt necesare pentru pornire sau care nu trebuie așteptate în timpul pornirii ar trebui să aibă opțional: adevărat cheie adăugată acestora. Acest lucru va preveni întârzierile mari la pornire pentru interfețele care ar putea să nu apară. (1)

Din nou, salvați, ieșiți și:

sudo netplan generate
se aplică sudo netplan

EDITAȚI | ×: Observăm acest lucru în mod repetat în jurnalul dvs.:

Conexiunea la AP b4:fb:e4:78:75:cd s-a pierdut

Vă sugerez să abordați setările din router folosind sugestiile mele aici: wifi-ul nu mai funcționează după un timp în timp ce este conectat în ubuntu 18.04
