Stream freeze

[Formaldehyde]

My first sky stream puck was replaced as it was freezing, stuttering, refusing to play TV and apps and eventually totally froze whilst on the call with sky help. The new puck is heading down the same road, it works fine for a while but everyday it stutters and today refused to play, totally locked out and the online help bot just cycles through a reboot - I am so tired of this puck. It is hard wired - no wifi and tried most things to fix it that have popped up on forums.

Expect you went through some of this with Sky.

Having a good local network broadband reach is key to Sky Stream.
Not just broadband speed to your house and router, but for your local network supply via wifi or ethernet, that can be affected in a busy household.

Best way to test is via a network speed test on each of your Pucks.
Launch Netflix on your pucks (you do not need to be logged into it, if you do not use netflix) and scroll down on the left menu to Get help.
Choose Check Network.
Would suggest running the test a few times, over say a half hour period during tests.
What is your speed for each puck?

Also, it may be suffering from interference,, the puck much like a Sky Q box can for some customers suffer from this at times. More often seen as an intermittent blip.
Not always a cure, but the following may help to resolve;
Make sure you have a good 6-8 inches free on all sides of the puck.
Do not stack the puck on top of any other device.
Best not to sit it on a glass shelf. Wood is generally the best.
Make sure the puck is in the open, not tucked away in a cabinet or sat directly behind the TV.
Make sure you have no other devices that can cause interference closeby, like cordless phones, radiators, baby monitors, smart meter in home displays, microwaves and the like.
You should be using the Sky supplied hdmi cable or a high speed equivalent one.

Plus, change both your pucks to following recommended settings set in Settings>
Turn wifi OFF under Network if connected via ethernet.
Set Network standby mode to ON and Overnight power saving to OFF.
