A Comcast tech added a new wifi network on my router
I recently upgraded to a new router. The tech that installed it said that because I am using a Google Mesh that he had to add a new wifi network on my router. He promised it would not be visible. Now I see that it is visible. Why is the new wifi network needed? And if actually needed, can I make it invisible without affecting any other features on my home network? There is currently nothing logged onto that new network.
