Ubuntu 20.04 LTS problem z WiFi

Question

Hej, zainstalowałem na swojego starego laptopa Sony Vaio SVF152A29M Ubuntu 20.04 LTS. Niestety nie mam możliwości połączenia się ze swoim WiFi (nie mam ikonki w prawym górnym rogu, ani zakładki w ustawieniach nazwanej Wi-Fi - jedynie sieć i połączenie przewodowe).

Próbowałem samemu rozwiązać ten problem, ale jest to mój pierwszy linux więc moja znajomość komend w terminalu jest znikoma. Próbowałem postępować tak jak na filmikach na yt doszedłem do etapu widocznego niżej, ale to nic nie pomogło. Oczywiście system zrestartowałem i dalej nic.

sudo lshw -class network

Answer 1

sudo apt install bcmwl-kernel-source

Hmm, czyli sterownik jest...

Wyłącz w BIOS-ie Secure boot.

---

wyłączyłem i teraz:

jk@jk-HP-ENVY-15:~$ sudo modprobe wl
modprobe: ERROR: could not insert 'wl': Invalid argument

---

Pokaż, co zwraca journalctl -b0 -p3

Spróbuj też:

sudo modprobe -r b43
sudo modprobe wl

 

---

Tak to wygląda:

jk@jk-HP-ENVY-15:~$ journalctl -b0 -p3

Nie widzę niczego w logach, co dotyczyłoby Wifi.

Internety mówią, by jeszcze sterownik ssb wyładować. Zrestartuj system i:

sudo modprobe -r b43 
sudo modprobe -r ssb
sudo modprobe wl
