虚拟机下8156 USB网卡速率不正常

ycljojo

昨天尝试了把爱快装在飞牛nas虚拟机里，硬件直通可以正确识别USB网卡（RTL 8156，2.5G），在爱快里lan口也正常识别2500M速率全双工，但是实测网速只有100M的带宽，请问这是什么问题，怎么解决？

把你爱快里网卡界面截图看看。你都直通了两个网卡还用虚拟网卡吗？

那个ETH0是什么情况，把ETH0删掉。

大佬你好，eth0是nas自带的PCI i226的有线网卡

显示-1M半双工是没工作吗？

玉尺书生

你LAN1只绑定2.5G网卡测试看看。

PCI的有线网卡是正常工作的，只是显示不正常，我看到有网友一样的情况也是正常使用

你LAN口绑定两个直通网卡？那你拨号怎么拨的？

拨号是用爱快的wan口（PCI 225V有线网卡）拨号的啊，我的nas是2.5G双网口的，又插了一个USB的网卡，USB网卡实际速率不正常

更严重的来了，飞牛nas访问不了了，但是虚拟机里的爱快可以正常访问，我猜测是实体网卡地址被虚拟机挟持了导致的，唉

爱快就直通那个双口的就行一个做WAN一个做LAN，没必要加个USB的
