Answer 1

The problem you must be trying to address is

Why your network connection is breaking after sometime

and not

How to repair your network connection every now and then

because if you are able to identify the root cause for first problem then you are done.

Answer 2

You could try and ping a widely used service in your country (or ping google like crazy) to detect internet connectivity. it's not bullet proof, but will let you know when your internet is down (probably).

The result of pinging could be checked by batch/script and according to the result, decide whether you want to ipconfig /renew or not.
