Saya mendapatkan kesalahan ini sebagai bagian dari masalah ini di sini tetapi karena masalah ini adalah masalah yang sama sekali berbeda, saya pikir lebih baik untuk mempertimbangkan masalah ini secara terpisah. Wlan0 saya turun. Ketika saya mencoba untuk menyalakannya
$ sudo ifconfig wlan0 up
SIOCSIFFLAGS: Operation not possible due to RF-kill
lalu
$ sudo rfkill list all

Apa artinya pesan kesalahan? Apa itu RF-kill?

. Kernel karena suatu alasan menolak kartu, seperti yang ditunjukkan oleh FF.

"SIOCSIFFLAGS: No such device"
. Saya menambahkan output dari lshow -command ke pertanyaan.Periksa apakah bluetooth dan nirkabel tidak beralih dengan buruk; verifikasi bahwa Anda harus memiliki situasi ini:
Saya memecahkan masalah saya dengan:
sumber
ifconfig wlan0 up
setelah perintah Anda untuk membuatnya berfungsi.Saya mengkonfirmasi masalah ini dengan laptop Asus X75VD menggunakan driver rt2600pci. Tidak ada saran di atas yang membantu saya, tetapi di forum Perancis (1), ada solusi yang berhasil. Cukup tangguhkan sesi (tutup penutup) dan aktifkan kembali dan wifi berfungsi.
Saya memposting ini karena utas lainnya khusus untuk Asus X75VD ditandai sebagai duplikat, dan model ini tidak memiliki tombol on / off fisik untuk wifi, dan urutan tombol fn tidak berfungsi dalam kasus ini.
Tampaknya juga merupakan regresi yang diperkenalkan oleh bot (2)?
Semoga akan ada tambalan yang segera hadir.

rfkill
dll. Tetapi tidak mungkin bagi saya untuk mendapatkan pemblokiran yang lunak dan keras pada saat yang bersamaan. Cukup aneh ini memecahkannya untukku! Terima kasih.Penanganan masalah tanpa harus menunda sesi
Memiliki laptop Asus yang serupa, saya memiliki masalah yang sama dengan wifi dan menggunakan solusi sesi penangguhan ini dan itu cukup merepotkan harus ditangguhkan setiap kali.
Namun, saya telah menemukan solusi di forum Fedora yang juga berfungsi di Ubuntu (mungkin berfungsi untuk semua distro):
Sebagai root, buat file dengan nama seperti
asus-wifi.conf
di/etc/modprobe.d/
mengandung:Setelah mem-boot ulang, wifi seharusnya menyala.
sumber
Saya memiliki masalah yang persis sama dengan Fujitsu Celsius H250:
Ini memberi saya:
Di laptop ada 2 slot mini-PCI-e. Satu PCI-e (yang kanan) diisi dengan kartu WiFi dan yang lainnya kosong, saya hanya memindahkan kartu WiFi ke slot lainnya (ke kiri) dan semuanya menjadi baik-baik saja.
Salam LAZA
