Please fix the functionality of the code - to check connections

In the old TOS 6, I used this function to check connections. It checked the gateway, DNS servers and selected IP addresses on the internet.

It indicated the start of the check and if there was a connection error, the type of connection.

After changing the syntax it is not functional.

I will ask a willing and knowledgeable person, who will not cost too much time, to make the necessary modifications fiel to make it work on the current version, please
