    本来是上传也是 800M 左右然后搜了一番。好像是驱动有问题 然后我把 openwrt 里面 R8169 和 R8125 驱动删掉了就剩一个 R8168 就现在这样了= = 是不是 RTL 就是这样。。。 win 还没试等有时间机子装个 win 试一下。看看是不是驱动问题。 机子处理器是 N5105 俩个 RTL8111 硬盘是 m2 的 sata 固态 内存两根 2g 的 ddr4 .

    感觉贼奇怪 笔记本直接连软路由，上传也变成 800M 。连交换机上上传变成 940M

    一般来说，先考虑换个驱动

    网络重置下看看。。。
    netsh winsock reset
    netsh int ip reset
    netsh int tcp reset

    笔记本插上电了吗，CPU 单核性能不够也跑不满

    软路由不带 NAT 芯片，交换机带有 NAT 芯片，所以内网传输速度不一样。
    可以参考这个帖子：
