Why does TiviMate only buffer at night?

Evenings are peak hours, when many people in your area use the internet at once. Your ISP and the stream server both get crowded, so your stream gets less speed.

What is the best buffer size for TiviMate?

About 5,000 ms (5 seconds) works well for most homes that buffer in the evening. You'll find it under Settings → Playback → Buffer size in TiviMate 5.x.

Does a bigger buffer slow down channel switching?

Yes, a little. A larger buffer saves more video before playing, so channels take a moment longer to start. In return, playback stays steadier.

Does changing DNS stop TiviMate buffering?

It can help if your ISP's DNS is slow at busy times. Setting Cloudflare DNS (1.1.1.1 and 1.0.0.1) on your router is a quick step worth trying with the other fixes.

Is Ethernet better than Wi-Fi for TiviMate?

Yes. A wired connection avoids crowded Wi-Fi and gives a steadier speed. If you can't use a cable, connect to the 5 GHz band.

How do I know if my IPTV provider causes the buffering?

Buffering on every device at the same time each evening, while other apps run fine, points to the server. In that case, a provider with a stable server cluster is the real fix.

Will clearing the cache delete my TiviMate playlists?

No. "Clear cache" only removes temporary files. Just avoid "Clear data", because that resets the app and removes your playlists.

TiviMate Buffering During Peak Hours? Buffer Size Tweaks 2026

TiviMate usually buffers in the evening because more people are online, so your stream gets less speed. Raise the buffer to about 5,000 ms, switch to Cloudflare DNS (1.1.1.1), and use a wired connection. If it still stalls, the provider's servers are the likely cause.

Why TiviMate Buffers More During Peak Hours

Peak hours are the busy evening hours. That is when most people in your area stream, game, and browse at the same time. Your home line shares the same roads as everyone else's.

Media research sites like eMarketer and The Information often cover how fast streaming keeps growing. More viewers means more crowded networks at night.

When TiviMate shows a spinning circle, one of these things is usually going on:

Your internet provider (ISP) is crowded. Speed drops when the whole area is online.
The stream server is overloaded. Too many users pull from the same server.
Your buffer is too small. A buffer is a short saved chunk of video. A small one runs out fast.
Your home setup is weak. This includes poor Wi-Fi, a full app cache, or a slow device.

Fixes Ordered From Fastest to Hardest

Start at the top. Each fix takes a little longer than the one before it. After each step, test a live stream during the evening.

Full App Cache → Clear the Cache

The cache is temporary data the app stores to load faster. Over time it fills up and can slow playback.

On Android TV or a TV box, open Settings → Apps → TiviMate.
On Fire TV, open Settings → Applications → Manage Installed Applications → TiviMate.
Pick Clear cache. Do not pick "Clear data", because that wipes your playlists.
Reopen TiviMate and test a stream.

Overloaded Device → Restart and Close Background Apps

Streaming boxes have limited memory. Apps left running in the background compete with TiviMate.

Close every app you are not using.
Unplug the device for 30 seconds, then plug it back in.
Restart your router the same way.
Open only TiviMate and test again.

Buffer Too Small → Raise It to 5,000 ms

This is the main tweak for evening buffering. A bigger buffer saves more video ahead of time. Short speed drops then don't freeze the picture.

The unit "ms" means milliseconds. 5,000 ms equals 5 seconds of saved video.

In TiviMate 5.x, open Settings → Playback.
Find Buffer size.
Pick a larger option than the default. Aim for about 5,000 ms.
Restart the app so the change takes effect.

The trade-off is a slightly slower start when you switch channels. Most people find that worth it in the evening.

Slow DNS → Switch to Cloudflare DNS (1.1.1.1)

DNS works like a phone book for the internet. It turns web addresses into numbers your device can reach. Some ISP DNS servers get slow at busy times, which delays how fast streams connect.

Cloudflare DNS is part of the recommended setup to deal with ISP slowdowns. The easiest way is to change it on your router so every device uses it:

Log in to your router's admin page. The address is usually printed on the router.
Find the DNS settings, often under Internet or WAN.
Set the primary DNS to 1.1.1.1 and the secondary to 1.0.0.1.
Save, restart the router, and test TiviMate.

Weak Wi-Fi → Use Ethernet or 5 GHz

Wi-Fi gets crowded in the evening too, since neighbors' networks fight for the same airwaves. A cable avoids that problem completely.

Best: Connect an Ethernet cable from the router to your TV box or TV.
Fire TV Stick 4K Max: Use a USB Ethernet adapter made for Fire TV.
No cable possible: Join the 5 GHz Wi-Fi band. It is faster at short range.
Placement: Move the router closer. Keep it out of cabinets and away from metal.

Quality Too High for Your Line → Pick a Lower Stream at Night

4K streams at 60 fps (frames per second) need a strong, steady line. If your speed drops at night, a 4K stream may not keep up.

Run a speed test in the morning, then again during the evening.
If the evening number is much lower, choose an HD version of the channel at night.
Keep 4K for times when your line is calm.

Many 4K streams use HEVC. HEVC is a video format that packs high quality into a smaller file. It still needs a device that can decode it smoothly.

Overloaded Provider Servers → Move to a Stable Service

This is the hardest fix, but it is often the real cause. If everything in your home is fine, the problem is the server. When too many users share one overloaded server, no buffer setting can fully save you.

Here is how to spot it:

Buffering happens on every device in your home, not just one.
Other streaming apps work fine while TiviMate stalls.
The problem shows up at the same time every evening.

Buffer Size Compared: Which Setting Fits You?

Use this table to pick a buffer size based on how you watch.

Buffer Setting	Channel Start Speed	Handles Evening Speed Drops	Best For
Small / default	Fastest	Poor	Strong wired lines with quiet evenings
Medium	Fast	Fair	Stable Wi-Fi with small dips
About 5,000 ms (recommended)	Slight delay	Good	Most homes that buffer at peak hours
Very large	Slowest	Strong, but more delay	Weak lines where stability matters most

A bigger buffer is not always better. It covers short drops, but it cannot fix a line that stays too slow all evening.

Devices and Players That Work With These Tweaks

The same steps apply across popular devices. Only the menu names change a little.

Devices: Fire TV Stick 4K Max, Samsung Smart TV (Tizen), LG webOS, Android TV Box, Xiaomi Mi Box S, and Apple TV.
Players: TiviMate 5.x, IBO Player Pro, IPTV Smarters Pro, Kodi 21, and Flex IPTV.

In other players, look for a setting called "buffer" or "cache" in the player or playback menu. Use the same 5,000 ms target.

What to Do If Nothing Worked

If you tried every fix and TiviMate still buffers each evening, your home setup is probably not the problem. The weak link is the server that sends the stream.

A service built for busy hours makes a real difference. SubTV IP offers a premium subscription with:

99.9% uptime and an anti-freeze server cluster that spreads the load.
4K / 60 fps HEVC streams for sharp, smooth video.
Instant activation right after your order.
Plans of 1, 3, or 12 months, paid securely with PayPal or credit card.
WhatsApp support to help you set up TiviMate, DNS, and buffer settings.
