Wi-Fi interference is unwanted radio activity or overlapping use that makes wireless communication harder. It can involve neighbouring networks or other equipment using relevant frequencies. Its effects vary with location and time, and it is one possible source of poor wireless delivery rather than proof that the internet connection or a media account is failing.
A practical example
Playback may become less reliable when nearby radio activity increases, even though the television and router have not moved. A controlled wired comparison or measurements at different locations can help distinguish a wireless contribution from a programme-specific problem.
A common misunderstanding
Repeatedly changing channels without recording results can make diagnosis harder. Use settings supported by the router and local rules, and compare a consistent test rather than judging only one short playback attempt.
