UCB Wireless - Known Issues

Last Updated: 04/03/2017

Apple TV and Google Chromecast

  • Impact: Apple TV and Google Chromecast devices cannot be used on the UCB Wireless network. Apple TV and Google Chromecast rely on a network protocol that requires multicasting to stream content over a network. While multicasting works well over small networks, it causes performance issues for large networks such as UCB Wireless and therefore it is not enabled at CU Boulder.
  • Workarounds: At this time there are no workarounds.

A Weak or Spotty Wireless Signal

  • Impact: Wireless signals can be affected by environmental issues such as bookcases, desks, and other large furniture, as well as interference from 2.4 and 5 GHz phones, microwave ovens, Bluetooth devices, and wireless game controllers.
  • Workarounds: Use a wired connection whenever available.

Security Issues With Wireless

  • Impact: Wireless service is shared with other users and is inherently less secure than wired connections.
  • Resolution: Whenever sensitive data is transmitted on wireless, a VPN should be used for secure data transmission.
