![从 17.04 升级到 17.10 后,Open wifi DNS 不起作用](https://linux22.com/image/896940/%E4%BB%8E%2017.04%20%E5%8D%87%E7%BA%A7%E5%88%B0%2017.10%20%E5%90%8E%EF%BC%8COpen%20wifi%20DNS%20%E4%B8%8D%E8%B5%B7%E4%BD%9C%E7%94%A8.png)
我的房间有这个开放的 wifi 热点,您可以公开连接,然后询问密码(由大楼管理部门提供)。
升级到 17.10 后,我可以连接到 wifi 网络,但加载一段时间后(我可以从建筑物中看到这个“正在加载”的站点),出现 DNS 错误,我无法登录或加载任何其他站点:
昨天添加了 google DNS 并在某个时候开始工作(需要多次重新加载和尝试),但今天我无法让它再次工作(没有改变任何东西)。
我一直在尝试找到解决此问题的不同方法,但直到现在还没有解决方案。
从我的手机(通过 wifi)创建和共享网络似乎可行,但这个热点却无济于事。
我注意到的一件事是,每次我启动计算机或重新启动网络管理器时,ubuntu 都会创建一个热点,因此每次我都需要停止它并选择我的网络。
