Kablosuz bağlı, ancak internet erişimi yok


18

Ubuntu 15.04 canlı kullanıyorum, wifi'ye bağlıyım, ancak Firefox'u açtığımda "Sunucu bulunamadı" dedi, Yazılım Güncelleyicisini açtım İndirilemedi, temelde internet erişimi yok. Ama daha önce ubuntu 14 kullandım ve wifi normalde herhangi bir hata olmadan kullanabilirsiniz. Ayrıca Windows ve telefonum da hatasız çalışıyor. Birkaç kez temiz yeniden yükledim ve aynı sorun var.

Durumum hakkında bazı bilgiler:

Wifi cihazım: Huawei HG8045A

/Etc/resolve.conf içinde belirttiğiniz üç DNS sunucusu için ping sonucu ekleyebilir misiniz?

Anlamıyorum, hangi adrese ping atmamı istiyorsun? @mgor

Ubuntu forumlarına soruyorum ve çok hızlı cevap veriyorlardı ve işe yaradı.

Click on Network Manager> 
Click 'Edit' 
Edit the wireless connection>
Click the IPv6 tab>
Set IPv6 to ignore>
click OK>
Reboot.

Bir cazibe gibi çalıştı!

Cevap için teşekkürler. Benim için Ubuntu 15.10 işletim sistemimde çalışıyor.

Bu yöntem çalışıyor ama bazen wifi hala bırakarak / bağlan ama çalışmıyor. Ne truongnm durumu yapmak dışında, yapılacak başka bir şey modemi bağlı olabilir veya olmayabilir modem yönlendirici ayarları ipv6 devre dışı olduğunu bulmak.

Bir Android telefonunuz varsa, Wi-Fi adaptörü olarak da kullanabilirsiniz ... Bunu birkaç kez yapmak zorunda kaldım ve çok iyi çalışıyor.

  • telefonunuzdaki mobil verileri kapatın.
  • USB internet paylaşımını açın (telefonunuzun wifi özelliğini kapattığı için sadece kişisel etkin noktayı açmayın).
  • telefonunuzla PC arasındaki bağlantıyı köprülemelidir.

Bu, sorunu çözmek için iyi bir örnektir, ancak sorunu değil. Umarım bu gerçekten neyin yanlış olduğunu bulana kadar geçici bir düzeltme olacaktır.
