Questions about "network"

Hello everyone,
This may be an old problem.
I know that to execute the “network” command, you need to arrange the lines in order.
I also used this instruction many times, but sometimes it was really speechless,it just didn’t respond.
do you have ever encountered such a situation? Or am I lucky to always encounter this situation ~ " (40 KB)

Sorry to retract this question, I know where it went wrong
