我在北京见到的有 4G+的地方，最高的一次跑到了 220Mbps 。

看来现在只有北京电信通还是纯正的鹏博士线路

下载速度 564.68 Mbps 上传速度 357.84 Mbps 延迟 47.00 ms 抖动 4.38 ms

@ttvast 网上的大神有很多都是这么搞笑的。

校园网 (电信联通移动教育网鹏博士多出口)
N3710 软路由
H3C Mini S5G-U 交换机
2*K3 AP

买个 H3C 那个 99 的交换机就足够用了。

只有一级的话，难道电信的 cn2 都是靠代理出去的？

@azhangbing 好内涵的回答。

很简单，下载一个 Minecraft 服务端，运行，让你喜爱 Minecraft 的小伙伴们连接一下就知道了。

这本质上体现的是一个人的语文素养，不应以此判定一个人的技术水平。
换言之，一个人的技术水平，和语文素养无关。

@seesea82 检查路由器防火墙设置

可以在路由器上使用 smartdns 作为科学工具出国部分 DNS，
smartdns 启用 force-AAAA-SOA yes 参数。
这样国内网站可以解析到 v4/v6 双栈，出国网站仅有 v4 。

我觉得楼上有几楼说的不对，可能是没用过这种网络。

这种有透传线路的运营商，只有传出时有透传。例如访问联通 IP，走联通透传出口，你查询到的 IP 也就变成了透传出口的 IP 。

但传入时是没有透传的。例如一个联通 IP 访问你本身的 IP，会正常走联通到鹏博士的路由，这之间没有透传。

这样的连接方式在校园网里常见，不会影响公网 IP 本身的性质以及作用，更不是“假公网 IP”。

光猫为什么要恢复出厂设置。。

第一个节点能测到 300Mbps，换了一个变成 50Mbps，又换一个变成 3Mbps 。。。
