how i can cut the internet connection for 1 min by cmd or something else?

I’m testing a remote computer having an access to our server, some of the tests require to cut the internet in order to see a specific behavior for our tests.

I’m using TeamViewer for this tests, I can disconnect the internet using TeamViewer, but i can't reconnect (TeamViewer connection will be lost).

how can I use TeamViewer to cut the internet 1 min and automatically the remote computer reconnect it self (If there a command for that?) ?
