Bea,
The problem you have is buffering. A bit like a traffic jam. Picture and sound data is coming over your wi-fi but something in the Firestick is causing a jam. There are several reasons why this could be happening:
1. Slow internet connection: It is recommended that you have at least 10 Mbps for HD and 20 Mbps for 4K streaming. If your internet connection is slow, you will experience buffering issues
2. ISP Throttling: Your ISP might slow down your connection speed from time to time if they detect too much streaming activities
3. Router far from FireStick: If your FireStick is placed too far from your router, your signal strength will be weaker and will cause buffering issues
4. Running low on RAM: It is not uncommon for FireStick to run out of RAM. There may be many unnecessary apps running in the background
4. Running low on storage: Again, it is common among FireStick users. The device has only 8GB of space, a lot of which is already used up by the OS
5. FireStick overheating: If your FireStick is overheating, it is likely to cause buffering issues
6. Outdated FireStick OS: You may experience buffering issues on FireStick if it is running on an outdated OS
I am unaware of any compatibility issues with Sky Q and Amazon Firestick.
If you don’t usually use the Firestick and haven’t used it in a long time and you say that other streaming services: Netflix and iPlayer are working fine then my best guess would be that the Firestick’s operating system (OS) is out of date.
Go to your Settings (the little wheel)
Choose My Fire, About, Check for Updates and download any that are available.
Does that fix it?
