ITS understands that our students and residential employees expect the same network experience as they would have in a private residence. However, certain consumer-grade technologies do not meet the security requirements of the university network.
Why can't I use my Chromecast on the university network?
Devices such as Chromecasts, wireless speakers, or smart bulbs "multicast" - broadcast their identity to all other devices connected to the network. This does not prevent unauthorized users from connecting to these devices and interacting with them. This works in a private residence where all the users connected to the network are authorized to interact with devices that multicast. With multicasting, the identity of devices would be broadcast across the entire network, and anyone attempting to connect to one of these devices would be able to do so without the consent of the device owner.
Why can't I play certain games online?
The Fairfield University network uses a strict Network Address Translation (NAT) type to provide over a thousand external IP addresses for the university network. Many gaming consoles will perform poorly in this type of network environment. ITS is constantly working to maintain its infrastructure to meet the needs of students, faculty, and staff. At this time however, the network cannot be adjusted to accommodate this need of gaming consoles.
