无线连接但无法访问互联网
我正在使用ubuntu 15.04生动，我已连接到wifi，但当我打开Firefox时，它说“服务器未找到”，我打开软件更新程序，它说无法下载，基本上没有互联网访问。 但我之前使用过ubuntu 14，我可以正常使用wifi而不会出现任何错误。 我的Windows和我的手机也没有任何错误。 我有几次清理重新安装，我有同样的问题。
以下是有关我的情况的一些信息：
我的wifi设备是：华为HG8045A

我不明白，但有时我在Firefox中刷新页面，它工作但非常短，约一分钟，它再次说“服务器未找到”。
好吧，我在ubuntu论坛上问他们答案非常快，而且很有效。
Click on Network Manager> Click 'Edit' Edit the wireless connection> Click the IPv6 tab> Set IPv6 to ignore> click OK> Reboot.
如果您有Android手机，您也可以将其用作Wi-Fi适配器……我必须这样做几次并且它的效果非常好。
- 关闭手机上的移动数据。
- 打开USB网络共享（不要打开个人热点，因为它会关闭手机的wifi）。
- 这应该桥接手机和PC之间的连接。
