Ubuntu 22.04 geen wifi-adapter "Powermanagement on"

[Nassara]

Ik heb een Lenovo Yoga en gebruik Ubuntu 22.04. Bij de herinstallatie heb ik opnieuw geen wifi-adapter en dus geen wifi-verbinding. Ik had dit probleem al in het verleden, de tip van Pjtor leidde me toen naar deze pagina:
https://makkelijkelinuxtips.blogspot.com/p/internet.html#ID3.1

Waar ik de "powermanagement" kon uitschakelen, en nadien had ik telkens wifi-verbinding. Maar sinds de herinstallatie lukt het niet meer; als ik in de terminal het commando
sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
uitvoer, en ik herstart de laptop, dan is er geen wifi en staat powermanagement nog steeds op 'on'.

Wat kan ik doen? Heel erg bedankt voor de hulp!

Wat zegt:

Code: [Selecteer]

cat /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

[Nassara]

cat /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf geeft

owersave-on.conf
[connection]
wifi.powersave = 2

[Pjotr]

Dat is goed. Wat zegt:

Code: [Selecteer]

iwconfig

[Nassara]

iwconfig:

lo        no wireless extensions.

Ik heb intussen Ubuntu 22.10 geïnstalleerd, en daar werkt de wifi (voorlopig) wel. Geen idee wat er fout ging. Bedankt voor de hulp, alleszins!!
