UBUNTU 14.04 ile Wifi Düşüyor ve Yeniden Bağlanıyor (Realtek RTL8188)

13

Toshiba Satellite C655D'ye UBUNTU 14.04 LTS'yi yeni yükledim. Benim wifi bazen düşer ve yeniden bağlanmak için tek yapmam gereken benim wifi devre dışı bırakmak ve wifi sağ üstteki kablosuz simgesinden etkinleştirmek. Sadece sinir bozucu.

Herhangi bir yardım mutluluk duyacağız, UBUNTU için yeniyim, ancak linux komutlarını öğrenmekle ilgileniyorum. Neyse ki bazı komutlar DOS ve toplu iş koduna benzer.

Bir yönlendirici kullanıyorum ve şu anda 14.04 çalışan başka bir dizüstü bilgisayar da dahil olmak üzere diğer kablosuz cihazlarla ilgili hiçbir sorunum yok, ancak daha eski bir Aspire One.

Forumda bulduğum wireless_script'ten bilgiler:

Kablosuz 'n' neden bir sorundur ??
— user2160518

Yanıtlar:

Önce yönlendirici değişiklik 802.11bgniçin 802.11bg.

İkincisi, wep şifrelemeyi (TKIP) değil sadece wpa2 (CCMP) (AES) olarak değiştirin.

Üçüncü olarak yönlendiricideki kablosuz kanalınızı 1 veya 11 olarak ayarlayın, ardından yönlendirici yapılandırmasını kaydedin ve yeniden başlatın.

Dördüncü olarak, ekranın sağ üst köşesindeki ağ yöneticisine gidin ve bağlantıları düzenle> kablosuz sekmesine tıklayın ve IPV6'yı yok sayacak şekilde ayarlayın.

Şimdi CTRL + ALT + _T terminalini açın, ardından doğruluk için aşağıdaki kodu bir kerede bir satır kopyalayıp yapıştırın:

echo "options rtl8192ce swenc=1 ips=0" | sudo tee /etc/modprobe.d/rtl8192ce.conf
sudo modprobe -rfv rtl8192ce
sudo modprobe -v rtl8192ce

Teşekkürler, sadece Ubuntu 15.04 çalıştıran dizüstü bilgisayarımda yaptım ve çalışıyor gibi görünüyor.

Harika! Bir haftadır mücadele ediyor, şimdi Ubuntu 14.04 üzerinde çalışıyor. Çok teşekkür ederim.

Aynı sorunu yaşadım - tembeltim, bu yüzden sadece 4 yaptım.

"ekranın sağ üst köşesindeki ağ yöneticisine gidin ve bağlantıları düzenle> kablosuz sekmesine tıklayın ve IPV6'yı yok sayacak şekilde ayarlayın"

... ve işe yaradı! Teşekkürler

Kabul ediyorum, bu kartı yıllardır kablosuz n'yi yalnızca birden fazla dizüstü bilgisayarda kullanıyorum ve ipv6'yı devre dışı bırakmak, gerekli olan tek şey, belki de ekstra mesafe için iwconfig'de daha büyük bir sayıya yeniden denemek dışında.
