• Browser: Google Chrome, Mozilla Firefox, Apple Safari or Microsoft Edge.

• Internet: Use a strong internet connection, 5 Mbps minimum but 15+ Mbps recommended, to avoid buffering or slowdowns.

• Audio: The speakers that come built into most computers are adequate, but headphones or a separate speaker will create the best audio quality and experience.

You can watch sessions from a mobile device, laptop or desktop. Most computers/phones purchased within the past few years will meet the minimum requirements.

Please note that if you pause the livestream on your computer for more than 15 minutes, you will need to log out and log back in to ASTRO.org.

If you are experiencing technical difficulty with the livestream, please try these troubleshooting steps:

• If the livestream video won’t play, then please note:
  • Some institutions have robust security measures that will block some virtual features.
    • Disconnect from a VPN (virtual private network).
    • If you are at a work institution, try another network like a mobile device or home network.
  • Clear your web browser history and cache or try another browser.
  • Completely log out of ASTRO.org and log back in.
• If the livestream is slow to load or buffers frequently:
  • Check your internet connection. A minimum of 5 Mbps is required, but 15+ Mbps is recommended. You can check this at www.speedtest.net.
  • Use a hard-wired internet connection, if possible. If you have to use Wi-Fi, make sure you are close to the Wi-Fi device.
    • If you are at the Symposium in Palm Desert, the attendee public Wi-Fi may not support streaming.
  • Close any other windows/tabs that may be using a lot of bandwidth.
  • If you are at home, make sure you are not also using streaming services like Netflix, etc., that could impact your available bandwidth.

If the steps above do not resolve the issue, please contact ASTRO eLearning by email or at 703-502-1550, option 2.
