DNS 只能设置 192.168.1.1,其他的都不能上网。

win10 现在是不管设什么都忽略，只用 192.168.1.1，访问 ipleak.net 发现的

你是不是设置的网关…

既然都知道 dns 这玩意了你就不能先自测一下吗

nslookup 指定 DNS 服务器查一下

路由器设置了 DNS 劫持，可能劫持没做完整。

关 win10 什么事？

换其他 DNS 也是 DNS request timed out.

手机连接，DNS 自动获取 192.168.1.1 可以用，也可以自己指 114.114.114.114 ，就只有电脑是这个样子

感觉是防火墙或者什么软件阻止了？

移动宽带？
192.168.1.1 本质上还是使用运营商的 DNS。

上回在 apple store 遇到了类似的情况，只有设置了他们家的 DNS 才能上网，并且干掉了所有 22 端口的访问。
本质上就是 iptables 之类的东西配出来的吧

运营商 192.168.1.1 路由 nat 到家里面？或者你路由器是开了酸～，DNS 劫持到酸～的话也需要这样设置

你的 ISP 屏蔽了公网 53 端口，只允许拨号 DHCP 分配的 DNS 服务器，然后你的路由器获取 DHCP 后成为 DNS 代理。
于是你只能用 192.168.1.1，你进去路由器看看获取的 DNS 地址，也只能用那两个。

可以用 DOH 之类的技术配置本地代理服务器来解决

其实很奇怪。无线网络可以自定义 dns,有线网络就不行。只能自动获取，由路由器分配 IP 和 DNS 才可以上网。但是无线和有线连接的是同一个路由器啊。
