原来用 wireguard 回家，使用 rdp 远程桌面流畅丝滑，上个月就出现卡顿，内网应用也是一样，大家帮看看什么原因，困扰多日，万分感谢！！！

测试速度符合家庭宽带上传的速度，无论使用 wireguard 还是 openvpn ，用联通手机做热点或者联通宽带回家，远程桌面卡成 ppt ，不可用，用移动手机做热点回家，远程桌面有卡顿，但是可以接收。

疑问：

使用 wireguard 建立连接

1. 联通是否限速了，如果限速，wireguard 建立之后的 iperf3 的测试也正常。
2. 为什么移动热点回家，网速正常，联通网络回家，非常卡。联通对自己内部网络进行限速吗？
3. rdp 卡是因为 wireguard 丢包严重吗？如何解决，使用 udp2raw ，还是什么方案。
