Windows Batch: Automatic check of network connectivity

Detecting network Connectivity I'm using the Cong approach, which is " External Network -- Gateway -- Intranet -- This machine " , the implementation of the script is also based on this order Ping to detect, in order to improve the detection speed, here I only Ping the 2 times, you can make changes according to your own needs.

How to use the great gods will ...  copy code, save as . Bat after the file is executed.
