只能找到 wireless 的，就是没有 ethernet 的，求助求助，该如何是好。

世界上最好的解决方式就是恰好不需要解决，换 mac 吧，工友

lspci 如果都看不到，那就是没有了
lspci 看设备，并不需要设备被驱动作为前提 |

zizhoutong OP @julyclyde omg 我想是不是因为内核的缘故 无法识别。因为我这个机子是四年前的，之前是 win 系统可以有线连接，最近换成 ubuntu 了。

@zizhoutong 这事跟内核没多大关系。既然能认出总线上其他设备，说明内核对总线的访问是正常的

记得很早之前有个 bug 是：windows 下休眠，linux 下就再也看不到网卡了。bios 里面禁用网卡再启用事实。如果 bios 不支持禁用板载网卡声卡等，记得今后不要买该品牌的产品了。
