It sounds backward, but a large buffer setting can make buffering worse, not better, because it makes the app wait longer to accumulate video before it starts or resumes playback. Apps like TiviMate let you set buffer length manually, and setting it to none or the smallest available option is one of the two settings that reliably helps across different connections. This isn't a universal fix for every cause of buffering, but it's cheap to test, takes seconds to change, and rules out one specific cause immediately. Test it before you touch anything on the network side, since it costs nothing and takes less time than a router restart.

Your DNS resolver translates the server address your app needs into something your device can actually connect to, and a slow or overloaded resolver adds delay before a stream even starts loading, which can look identical to buffering. Switching to a public DNS resolver is the second setting that reliably helps, alongside a minimal buffer setting. It's a five-minute change in your device or router settings, and it costs nothing to test even if it turns out not to be your specific cause. Pair it with the buffer change and you've covered the two settings most worth trying first.

Player apps keep your entire channel list in memory while they run, and performance commonly degrades once that list grows past roughly 18,000 visible channels. If your service carries tens of thousands of channels and you've never trimmed what's visible, the app is working harder than it needs to just to stay responsive, and that strain shows up as buffering that seems to happen everywhere, not on any one channel. Hiding groups you don't watch in your app's settings directly addresses this and is one of the few fixes for buffering that isn't about your connection at all.

If you've set the buffer low, switched DNS, and trimmed your channel list, and it's still buffering too much across multiple channels and multiple days, the remaining cause is usually either your actual bandwidth falling short of what your stream quality needs, or server capacity on the provider's side that no setting touches. At that point, dropping from 4K to 1080p to cut your bitrate need roughly in half, or checking a provider's uptime number, are the two moves left that are still in your control. Anything beyond that is the provider's servers to fix, not your device's settings.
