“SIOCSIFFLAGS: Operasi tidak mungkin karena RF-kill”?

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

0: phy0: Wireless LAN 

     Soft blocked: yes

     Hard blocked: no

1: tpacpi_bluetooth_sw: Bluetooth

     Soft blocked: yes

     Hard blocked: yes

Apa artinya pesan kesalahan? Apa itu RF-kill?

Ketika saya menerapkan saran Fossfreedom, saya mengerti "SIOCSIFFLAGS: No such device". Kernel karena suatu alasan menolak kartu, seperti yang ditunjukkan oleh FF.

Pemblokiran lunak

Output ke sudo rfkill listmenunjukkan bahwa kartu jaringan Anda "diblokir dengan lembut".

Ini bisa terjadi ketika kartu nirkabel telah diberi tanda untuk mematikan melalui kernel.

Coba langkah-langkah berikut:

1. berjalan di terminal:

   sudo rfkill unblock wifi; sudo rfkill unblock all

2. jalankan kembali sudo rfkill listuntuk mengkonfirmasi bahwa kartu telah diblokir.

3. reboot

4. jalankan sudo rfkill listkembali untuk mengonfirmasi pemblokiran yang telah dipertahankan.

5. jalankan kembali sudo lshw -class network- Anda seharusnya sekarang melihat bahwa kernel telah mengenali (atau tidak) kartu nirkabel.

Jika modul kernel nirkabel telah dikenali (seharusnya tidak mengatakan "tidak diklaim"), Network Manager sekarang seharusnya dapat melihat jaringan nirkabel yang tersedia di vitasitas Anda.

Diagnosis masalah kernel

Jika kartu jaringan tidak dikenali - dan Anda telah mengonfirmasi sudo rfkill listbahwa tidak ada pemblokiran (yaitu, baik yang diblokir maupun yang diblokir adalah "tidak"), maka tambahkan yang berikut ke pertanyaan Anda:

sudo modprobe -r iwl3945
sudo modprobe iwl3945
dmesg | tail -n 50

Semoga ini akan menunjukkan kesalahan - misalnya masalah firmware tidak memuat.

Memuat firmware baru

Jika ini masalah firmware, Anda dapat mencoba salah satu dari yang berikut ini:

• instal driver nirkabel backports:

yaitu

sudo apt-get install linux-backports-modules-cw-2.6.39-generic

Kemudian reboot - tes untuk pemblokiran perangkat lunak dll.

• dapatkan firmware terbaru sebagai berikut:

yaitu

wget http://intellinuxwireless.org/iwlwifi/downloads/iwlwifi-3945-ucode-15.32.2.9.tgz

tar xzf iwlwifi-3945-ucode-15.32.2.9.tgz

cd iwlwifi-3945-ucode-15.32.2.9

sudo cp iwlwifi-3945-2.ucode /lib/firmware

Kemudian reboot - tes untuk pemblokiran perangkat lunak dll.

NB jejak dmesg Anda harus menunjukkan apa nama firmware yang bermasalah. Mungkin Anda perlu mengganti nama "iwlwifi-3945-2.ucode" menjadi apa pun nama firmware yang diharapkan.

Periksa apakah bluetooth dan nirkabel tidak beralih dengan buruk; verifikasi bahwa Anda harus memiliki situasi ini:

$ sudo rfkill list all
0: hci0: Bluetooth
    Soft blocked: yes
    Hard blocked: no
1: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no

Saya memecahkan masalah saya dengan:

$sudo rfkill block bluetooth
$sudo rfkill unblock wifi

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.

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.confdi /etc/modprobe.d/mengandung:

options asus_nb_wmi wapf=1

Setelah mem-boot ulang, wifi seharusnya menyala.

Saya memiliki masalah yang persis sama dengan Fujitsu Celsius H250:

14:00.0 Ethernet controller: Atheros Communications Inc. AR242x / AR542x Wireless Network Adapter (PCI-Express) (rev 04)
Subsystem: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01)
Kernel driver in use: ath5k

Ini memberi saya:

# rfkill list all
1: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes <--------- !!!
3: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no

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

Ini mungkin atau mungkin tidak membantu Anda, tetapi saya menggunakan komputer hp dan mengatakan hal yang sama, jadi apa yang saya lakukan adalah keyboard saya memiliki tombol WiFi di atasnya dan saya hanya menekannya sebentar dan ikon naik di bagian atas menghilang dan saya mengetik ifconfig wlan0 up Dan itu berhasil

nonaktifkan koneksi hardwire Anda dan tekan tombol keyboard yang memungkinkan perangkat nirkabel Anda. Inilah yang memecahkan kesalahan yang sama bagi saya.

Untuk ASUS R704V saya yang menjalankan Ubuntu 13.10 tidak ada proposal di atas yang berfungsi. Rupanya driver kernel dan perangkat keras tidak setuju tentang arti level logis "0" dan "1" sebagai "diblokir" dan "tidak diblokir".

Tapi saya menemukan solusi aneh yang masih berfungsi dengan andal:

• menangguhkan sistem ke RAM (baik dengan menekan tombol SUSPEND atau dengan menggunakan entri Tangguhkan di menu Logout di sebelah kanan panel atas)
• tunggu beberapa detik
• tekan tombol daya untuk memulai kembali sistem

Seluruh proses akan memakan waktu kurang dari 5 detik.

Output ke 'rfkill list all' akhirnya muncul

0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: asus-wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no

NetworkManager akan mengaktifkan WIFI dan harus menawarkan titik akses untuk terhubung.

Cara mengatasinya adalah yang sederhana seperti menekan Fn+ F2untuk mengaktifkan kartu nirkabel untuk laptop Dell saya.
