Usb Wifi Adaptör Sorunu

[Xgibi]

Laptopumda Lubuntu 18.04 yüklü. Laptopumun wifi alıcısı kötü o yüzden usb wifi adaptör aldım ama kuramıyorum. Windows da otomatik kuruluyor ve görüyor, yani bozuk değil.

2 wifi cihazı görünüyor, ikisi USB arabirimli. PPA deposunu ekleyip, ardından ek sürücüleri açıp gerekli sürücüyü  kurmayı deneyin. Depoda ikisi için de sürücü paketi mevcut.

https://forum.ubuntu-tr.net/index.php?topic=61308.0

Kurulumdan sonra sistemi yeniden başlatın ve secureboot varsa kapatmayı unutmayın.

Hangisini yükleyeceğimi anlamadığımdan rastgele yüklemeye başladım. İkinci denemede doğruyu buldum, rtl8822bu işe yaradı. Teşekkürler.
