Buffering can occur when the Internet connection is slow or unstable.
Try:
- Restarting your router and STB.
- Checking whether other devices are using heavy Internet bandwidth.
- Checking the connection between your router and STB.
- Using an Ethernet/LAN cable instead of Wi-Fi where possible.
- Checking your Internet speed.

What does Error 5221 mean?
Error 5221 may occur when ViaTV content is taking longer than expected to load and may be related to slow or unstable Internet connectivity.
What should I check?
1. Check how your STB is connected
Is your STB connected through:
- Ethernet/LAN cable?

Try switching between several channels.
- If only one channel is affected, note the channel name/number.

- Restart your router and STB.
- Move the router/STB closer where possible.
- Try Ethernet/LAN if available.
4. If connected through Ethernet
Restart your router and STB and check whether the error continues on all channels.
