Whenever there is live sport the connection keeps dropping in and out. There is nothing wrong with the router if wifi however having checked upload speed it is was only 2kb/s

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

Also, try a restart of your Sky Stream box

Go to Settings>Systems Management>Resets & Updates
Select Restart device
Your Sky Stream puck will perform a reboot. It will take a few minutes to complete
