Networking 局域网连接不稳定,WIFI正常工作

Networking 局域网连接不稳定,WIFI正常工作,networking,ip,wifi,ethernet,dhcp,Networking,Ip,Wifi,Ethernet,Dhcp,我刚买了一个cubox-i4,但局域网连接有一个大问题。它建立并再次崩溃。问题是,如果我通过局域网将其连接到机场快线(通过wifi连接),连接是稳定的(=>没有硬件问题)。与路由器的直接连接不起作用。以下是连接到路由器时的日志: May 8 23:45:29 linaro-ubuntu-desktop kernel: PHY: 1:04 - Link is Down May 8 23:45:30 linaro-ubuntu-desktop NetworkManager[2552]: <
