Saya baru saja memperbarui Boot pra-Aman saya, pra-UEFI* Toshiba 2012 Satellite P755-S5390 laptop dari 15.10 hingga 16.04. Di 15.10, adaptor nirkabel berfungsi dengan baik. Sekarang, Ubuntu menolak untuk mengakui laptop saya memiliki antarmuka nirkabel. Saya telah mem-boot ulang berkali-kali, melakukan hal berikut:
apt install flashrom librtlsdr* nictools* r8168-dkms rtl-sdr rtl8812*
Yang tampaknya berhasil, dan banyak hal lain yang saya temukan di 'net semua sia-sia. Additional Drivers layar Software and Updates memiliki satu entri, yang diklaim sebagai unknown atau not working correctly .
Network Settings adalah entri singkat (di sebelah kiri, dulu ada perangkat "Wifi" atau lebih):
(Sebelum Anda bertanya, tidak, tanda tambah kecil tidak membantu.)
Saya menemukan postingan ini di mana pengguna mengalami masalah serupa, dan mereka memposting banyak data dari sejumlah besar perintah, jadi saya akan melakukan hal yang sama di sini.

Namun adaptor wifi tetap tidak berfungsi setelah reboot.
*Laptop saya tidak pernah memiliki UEFI dan masih memiliki BIOS; akibatnya masalah saya tidak sama dengan driver Realtek RTL8723BE yang tidak berfungsi di Ubuntu 16.04 (kernel 4.4).
Jawaban yang Diterima:
Saya tidak tahu apakah Anda sudah melihat posting ini atau belum, tetapi begini. Tautan
Menurut jawaban dalam pertanyaan itu, tampaknya ada driver yang lebih baik yang tersedia oleh pengembang pihak ketiga yang memeliharanya di GitHub.
Terkait:DevOps berarti pengembang sekarang bertanggung jawab atas infrastruktur dan rilis – tetapi apa pendorong di balik perubahan ini?Jadi buka terminal (Ctrl+Alt+T) dan ikuti langkah berikut:
sudo apt-get install build-essential linux-headers-generic git dkms
git clone http://github.com/lwfinger/rtlwifi_new.git
cd /path/to/rtlwifi_new
make
sudo modprobe -rv rtl8188ee
sudo make install
sudo modprobe -v rtl8188ee
Semoga membantu
