Koneksi Wifi Tidak Stabil Ubuntu 14.04

9

Saya sudah membaca pertanyaan lain di askUbuntu, tetapi tidak bisa menyelesaikan masalah karena saya baru mengenal Linux.

Masalahnya adalah koneksi Wifi di Ubuntu 14.04 tidak stabil. Memang terhubung ke wifi untuk sementara waktu, tetapi setelah 5 menit tidak dapat menemukan sebagian besar jaringan (itu memang menemukan beberapa dari mereka).

Saya baru saja membelinya dari Mouse Computer. Tapi itu stabil di Windows 8.1 (dual boot) jadi sepertinya bukan masalah perangkat keras.

Saya sudah mencoba solusi di bawah ini.

  1. Tambahkan "opsi iwlwifi 11n_disabled = 1" di /etc/modprobe.d/iwlwifi.conf

  2. Abaikan IPv6

  3. Mulai kembali NetworkManager

Tak satu pun dari mereka memecahkan masalah.

Berikut ini informasi dari Ubuntu saya.

    ======== Done ========

Terima kasih sebelumnya.

btw, saya sedang belajar Ubuntu karena saya merasa lebih menyenangkan daripada mencoba mengatasi Windows. Saya dapat memutuskan untuk beralih platform utama saya ke Ubuntu karena komunitas Tanya Ubuntu. Terima kasih semua Geeks Ubuntu.

Saya perhatikan ini ketika saya menggunakan WPA untuk terhubung ke router. Coba gunakan WPA2 - itu berfungsi dengan baik untuk saya sekarang.

Saya sarankan Anda mencoba parameter driver. Silakan buka terminal dan lakukan:

sudo -i
echo "options rtl8723be fwlps=0"  >  /etc/modprobe.d/rtl8723be.conf
modprobe -r rtl8723be
modprobe rtl8723be
exit

Mungkin perlu reboot. Adakah perbaikan?

Terima kasih banyak! Ini berhasil dan sekarang saya memiliki koneksi yang stabil! Tapi sepertinya lebih lambat dari yang seharusnya (atau dibandingkan dengan windows).
— Yuu Jinnai
Yah, sepertinya itu karena saya menonaktifkan IPv6. Saya akan mengujinya besok.

Itu memecahkan semua masalah! Terima kasih banyak atas bantuan Anda. Apakah Anda akan dengan baik hati menjelaskan kepada saya apa penyebab masalahnya? Saya mencoba mencari tahu sendiri tetapi tidak dapat menemukan informasi.

@ SalathielGenèse Saran ini sekarang sudah hampir tiga tahun. Saya sarankan Anda mulai dengan pertanyaan baru dan mari mulai dengan yang baru.

Saya menambahkan baris berikut di /etc/modprobe.d/iwlwifi.conf:

options iwlwifi 11n_disable=1

options iwlwifi swcrypto=1

dan bug hilang!

Anda memiliki adaptor nirkabel yang berbeda. Jawaban ini sama sekali tidak relevan.
— Pilot6
Saya tidak pernah memposting apa adaptor jaringan saya. Jangan berasumsi sebelumnya. Mungkin ada lebih banyak solusi untuk masalah ini. Saya melakukan perintah "lshw -C network" dan adaptor jaringan saya adalah "RTL8723BE PCIe Wireless Network Adapter". Ini sama seperti dalam pertanyaan Sebelum berkomentar dulu "pikirkan".

Tetapi perintah yang Anda poskan sebagai iwlwifimodul pengaturan jawaban , yaitu driver untuk adapter nirkabel Intel. Ini tidak mempengaruhi adaptor Realtek dengan cara apa pun.
