Robust but complex solution:
Set up an encrypted VPN at the router level. Any encryption will work, even weak dumb encryption is fine. Any attempts to decrypt it would be mad illegal.
Turn off your SSID.
It is now functionally impossible to detect anything about the traffic or the Wi-Fi router without some serious or illegal methods.
You should really spend some time learning about WiFi signals. Tracking down rogue Access Points is a pretty common thing and having the SSID turned off does fuck all to prevent it. On the easy end, many enterprise wireless network controllers have rogue AP detection built right in and will show you a map of the location of the rogue AP. Harder, but still entirely possible, is running around with a setup just detecting the signal and triangulating it.
Yeah, I mistyped part of the sentence. Should have been "without some serious effort or illegal methods." Serious effort is well beyond most ISP's. They aren't sniffing wireless AP's then busting down doors to find out if its a 5g AP or an AP using their network. I actually know quite a bit about WiFi signals. I happen to be certified in Meraki (CMSS). If the uni said "no wireless signals" that would be a completely different story.
