（为了高效，请按如下格式提问）硬件主板型号：yy3568
固件名称/系统版本：Debian10

Log日志: (可以导出，用TXT附件上传)
问题描述及复现步骤:修改resov.conf文件后仍无法连接互联网，下面是/etc/network/interface文件内容 你好！两个网口都有尝试过吗？
可以先做回环测试：
cd /sys/devices/platform/
find -name "*ethernet*" // 找到网卡目录
cd XXX.ethernet // 进入网卡目录
echo 1000 > phy_lb // 出现PASS为通过（如果是100Mbps网线，请将1000改为100） 何浩钧 发表于 2024-11-4 18:00
