I know WIFI networks can be detected by their signal, but I was told that through some kind of network analysis on a wired network you could detect a WIFI router.
I'm on a network with around 500 computers. We have ethernet ports to connect to this networks. I was told not to connect a WIFI router because it was forbidden. I was told that a WIFI router would be detected by an automated tool that analyses the data that goes through the network. I have a friend who already has a router and has a computer without an ethernet port.
How is the traffic of a computer through the router different from the traffic of the computer plugged using the ethernet port?
