此時能夠看到輸出了DNS的IP，此時如果ping這個DNS的IP應該是可以ping通的，如果不能ping通是有問題的，對于4G，可以通過route -n查看網關的IP，此時可以看到網關的IP

root@myimx6ek140p:~# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 10.89.175.114 0.0.0.0 UG 10 0 0 eth2 10.89.175.112 0.0.0.0 255.255.255.252 U 0 0 0 eth2 192.168.18.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0

此時，ping網關IP：10.89.175.114,是無法ping通的，但是此時ping DNS的IP是能夠通的

但是今天遇到一個問題：ping quectel指定的DNS地址也是不通，這就很成問題了，有待解決
