Kablosuz bağlantı sorunu

9

Bu 13.04 bir sorun ve wifi ile ilgili bir sorun. Ubuntu asla ağa bağlanmaz. Diğer tüm aygıtlarım iyi çalışıyor.

Bilgisayar ağı algılar ve wifi parolası iletişim kutusunu açar. Doğru şifreyi giriyorum, ok'u tıklıyorum ve birkaç saniye boyunca bağlanmaya çalışıyor ve sonra tekrar şifre istiyor. Aynı ağa bağlanmak için pencerelerin altında iyi çalışan yeni bir D-Link Kablosuz N 150 Pico USB adaptörü kullanıyorum.

Google'da birkaç saat aradım ve bir yanıt bulamadım, belki burada biri yardım edebilir mi?

Inspiron N4010'umda sudo tail -f /var/log/sysloggörüntüler: Bir yoruma dahil edilemeyecek kadar uzun
— PHP Öğrenen
Biri Inspiron N4010, diğeri Latitude D630 olan iki farklı DELL Dizüstü Bilgisayar ile Ubuntu 13.10'umda da benzer bir sorun var. Sorunun her iki dizüstü bilgisayarda da aynı olduğundan eminim, ancak sorun WiFi'nin her ikisinde de ağlara bağlanma ile ilgili. <br/> Dizüstü bilgisayarlarımın 13.10'a yükseltmeden önce kablosuz ağlarla ilgili bir sorunu olmadı. Ubuntu 13.10'un tüm WiFi sorunlarına son bir çözüm var mı?

Kartı çok erken çıkarmaya meyilli olan kablosuz güç tasarrufunu kapatmayı deneyebilirsiniz:

sudo iw wlan0 set power_save off

Düzenleme: Bazı öneriler ...

Gönderdiğiniz çıkıştan ipv6'nın bağlanamaması olabilir

Bağlantıları düzenle> ağınızı seçip düzenle> IPV6 sekmesi> yöntemi "yoksay" olarak ayarla'yı tıklayın

Sertifikalarla sorun yaşayan diğer konuları gördüm: Kablosuz ağda kimlik doğrulama

  sudo nano /etc/NetworkManager/system-connections/YOUR-NETWORK-NAME

ve satırı (önüne bir # işareti koyun) yazın system-ca-cert = true

USB adaptörünüz için bir ürün yazılımı sorunu olabilir mi? Ethernet kablosuyla bağlanmayı deneyebilir ve yazılım güncelleyici ile güncelleme yapabilirsiniz.

Akla gelen son şey, sadece mevcut bağlantıyı silin ve baştan başlayın ...

Nasıl gittiğini bize bildirin

IPv6'yı ağda devre dışı bırakmak benim için sorunu çözdü, harika! Bunun neden böyle başarısız olacağına dair oldukça gizemli ...

Gördüğüm gibi dhclient IP'yi yönlendiriciden alamıyor. En az IPv6. Bu yüzden IPv6'yı "yoksay" olarak ayarlamaya çalışın ve / veya IPv6 / IPv4 kullanımını etkinleştirin / devre dışı bırakın. Bütün bunlar bana yardımcı olmadı (aynı günlüğüm var). IPv4'ü manuel olarak ayarladım. İlk olarak rastgele IP ayarladım ve yönlendiriciye bağlanıyorum. Burada internetim yok ama yönlendiriciye bağlıyım. Sonra yönlendirici IP bulmak için ağ nmap'ed: nmap 192.168.0.0/23 Ve sonra yönlendirici IP ağ geçidi olarak ayarlayın.

Bu tüm durumlar için bir çözüm değil ama bana bu gece otel ücretsiz wi-fi bağlanmak için yardımcı oldu. Ayrıca DNS ayarlamam gerekiyordu. Google herkese açık dns kullandım, ancak başka birini ayarlayabilirsiniz.
