Sky Glass / Sky Stream — smart-home gadget keeps going offline

Why does my Sky Glass / Sky Stream smart device keeps going offline?

The short answer

Picture freezes or drops quality during live TV in the evening. On the WiFiXpert Compatibility Index the Sky Glass / Sky Stream scores 62/100, and its weakest check is "Works on a guest network" — which is exactly where this problem comes from. Not designed to run on a guest network.

Free fixes, in order

  • Run a speed test standing where the TV is, not next to the router.
  • Ask Sky for a booster — they'll usually send one when you report the room.
  • Move the hub out of the cupboard under the stairs.

Before you spend anything

  • Sky's own boosters are free with the service, so ask before buying anything.
