Compare the connection on the same device with a second authorised video source. If only one source freezes, record the time and app version.
Test rather than assume
Check other apps, measure the connection near the television and compare Wi-Fi with Ethernet. Test the same source on another device only if you are authorised to use it.
Change one setting at a time
Close background apps, update software and improve router placement. Avoid changing several advanced settings at once.
When to contact support
If only one specific source has problems, record the time and error and report it to the provider. The fix may be outside your home network.
