无法连接到互联网,但可以连接到路由器

我使用的是 Ubuntu 17.10,在顶部主栏中看到一个问号代替了无线符号。我无法连接到互联网,但是我可以连接到路由器。我的 Windows 笔记本电脑上的互联网连接正常。

我试过了:

sudo service network-manager restart
sudo rfkill unblock all

这是 lshw:

sudo lshw -class network

可能是您没有将默认网关设置为路由器。尝试查看 的输出route -n并查看目标 列出的内容0.0.0.0

也可能是您没有获取 DNS。您可以尝试nslookup对某个已知 URL 执行此操作,看看是否能获取任何信息。
