The most common cause of Netflix streaming problems is a weak or unstable Internet connection. This sometimes points to a problem with your Internet rather than Netflix. At times, too many people in one area may be watching Netflix, which can lead to problems with the stream.
If the problem is not with your Internet service provider, streaming problems may be related to your Netflix settings. There could also be an issue with your home configuration that's causing problems while you're trying to stream Netflix. The Netflix help center offers a variety of ideas to troubleshoot whenever you're experiencing problems streaming.
