Multiple names for Network

My house is wired with 15 plug-in points. The router (a Cisco RV016) is connected to the cable modem. Most everything is working fine.

However, I recently noted that different plugged-in computers use different names for the Network (e.g., Network, Network3, etc.). Being OCD, I'd like to make these uniform. Any advice on how I can do this? Perhaps I can remove all network data from the computers and start from scratch. Advice welcomed.

 

Suppress your OCD, it isn't significant. You will be familiar with 'if it ain't broke ....'
