Tried rebooting it? 

Check your broadband - it needs to be fast and stable for Glass to function. 30Mbps minimum preferably, and try connecting via ethernet if WiFi is getting interference. 

Run the speed test on the Netflix app on the TV - navigate to the get help menu and run a network check.

@Mainy  I suspect your broadband is struggling.  One of the main reasons for freezing or buffering is the quality and speed of the WiFi signal being received at your Glass TV and not that being received at the router.  This can be checked with the Netflix App (Get help > Check network).  The minimum speeds recommended by Sky are as follows:

HD = 25mbps

UHD = 30mbps

HD + 1 puck = 30mbps

UHD + 1 puck = 35mbps

The important thing with Wi-Fi is to have a stable signal as both Glass and Stream are susceptible to problems if there is any signal fluctuation or interference.  For this reason an Ethernet connection is usually better than WiFi as it maintains better stability. If you try an Ethernet connection don't forget to turn off WiFi in Settings / Network / Advance settings.

If this is not practical (as in my own home) then you could consider Powerline Adapters which are about £35 on Amazon.  Don’t waste money on a Gb model as Glass and Stream Ethernet ports only support 100mbps.

"UHD + 1 puck = 35mbps"

Does that mean Sky claim it is possible to watch UHD content on two Sky Stream devices simultaneously with a stable router sync speed of 36 Mbps?

@Exiled-in-HH it greatly depends on what the usage is by the customer. 36Mb/s is ample for most people but if you are going to watch two UHD Sports streams at once you would probably hit issues. Watch two UHD movies would probably be just about OK but most peopke watch one or the other or in HD. 

When I first got my set up there were some stupid posts claiming you needed a gigabitfull fibre service for more than a single Glass TV. I had a FTTC connection at that time deliveing roughly 73Mb/s in speed tests. I ran as a test a F1 UHD broadcast on my Glass TV and main puck and the same broadcast on the other 2 pucks in HD. I could still run a speedtest at 20Mb/s while the streams were active.

Bandwidth Streaming requires varies which is why I used the same broadcast and UHD sport is fimed at true 50fps, is compressed in realtime and a fast moving sport like F1 with much camera panning is likely to maximise bandwidth requirement. A drama played at 25fps is likely to require miuch less and will have been compressed off line leading to more efficent data usage.

Isn't it strange that a single puck needs 30 Mbps to run UHD, but TWO pucks can run UHD with 35 Mbps🤔
