1. sudo lshw -numeric -class network
2. sudo ifconfig -a
3. sudo route -nv
4. sudo dhclient -v
5. sudo cat /etc/resolv.conf
6. sudo ls -al /etc/resolv.conf

这就是这几条对应的指令执行后的结果 求分析没法上网的原因

分析没法上网的原因

猜測 無法上網的原因 只是 無法解析 網域名稱 變成 IPv4 網址
1. 證明 猜測 對不對
1-1. sudo ping -c 3 198.71.86.201
1-2. sudo ping -c 3 forum.ubuntu.org.cn

2. 如果 1-1 是通的 1-2 不通
表示 無法上網的原因 是 無法解析 網域名稱 變成 IPv4 網址
