Not all services associated with Apple TVs, Roku devices, or Chromecast devices will work on the Harvard wireless network.
These devices were designed to work in home network environments, and therefore do not fully function on a campus network environment.
Specifically, these devices do not work across IP subnets, and require multicast services that are unavailable on the campus network. Many universities are experiencing the same issue with these devices.
Services that will work on campus:
Internet streaming from providers such as Netflix, YouTube, Hulu, Vimeo, Amazon, and others will work on the Harvard wireless network.
Services that will NOT work on campus:
Apple Airplay services will not work, including gaming, screen mirroring, and streaming content from a local device. Remote channel control of the Chromecast via phone or tablet will not work on the Harvard wireless network.
