Leave it to the professionals
This reminds me of an incident that happened to me some years ago now. We were setting up a new regional office in a building the company had leased several floors. One of the tasks we had was to setup networked printers. We had configured the IP on several of the printers when my manager decided to show us how it should be done. He opened up the web GUI and proudly showed us how to remotely set an IP. Suddenly we started getting alarms that network communication had been lost to main office and nothing external was pingable. He had set the the printer IP to the router gateway IP. Worse, he did know which physical printer he had set. So we had go to printers on several floors to find the offending printer. Later I left the company because I didn’t get along with the manager. He was fired from the company 2 days after I left.
