How to Stop Kodi Buffering Issues: We all love uninterrupted entertainment—nothing is more frustrating than constant interruptions. Kodi, a popular entertainment platform used by millions worldwide, offers high-quality, on-demand streaming content, mostly for free. While Kodi connects millions of users to thousands of streaming sources, buffering issues are unfortunately quite common. As more streams are added without proper oversight, buffering problems tend to increase. Thankfully, there are simple fixes to reduce or even eliminate buffering on Kodi versions 20 and 21. Keep reading to learn how!

How to Fix Kodi Buffering 2025

Kodi is a widely-used media player among cord-cutters around the globe. Created by XBMC, this app transforms your device into a full-fledged media center. It allows you to play and cast locally stored media using various add-ons and builds, as well as stream freely available content from the internet. Even better, Kodi supports a wide range of platforms, including Fire TV Stick, FireStick 4K, FireStick 4K Max Android, iOS, Windows Mobile, Windows PC, Mac OS, and Linux.

Kodi is undoubtedly a powerful media platform, but it’s not without its challenges. Some users may find it a bit more complex to set up compared to alternatives like Plex. However, once you get the hang of it, Kodi often becomes the go-to media player for many. But setup complexity isn’t the only concern. The most persistent issue with Kodi is buffering. Few things are more frustrating than constant pauses while you’re trying to enjoy a movie or TV show. The good news? There are effective ways to fix or significantly reduce buffering on both Kodi Omega 21 and Kodi Nexus 20. In this guide, we’ll walk you through the best methods to solve Kodi buffering problems—so stay tuned!

Enable Unknown Sources on Kodi

Before moving forward, there’s a small but important step to take care of. Kodi is built with security in mind to ensure a safe entertainment experience. As part of this, it restricts installations from unknown third-party sources by default to prevent potentially unsafe builds or add-ons from being installed. However, not all third-party add-ons are harmful—especially the ones we’ll cover in this guide.

To install these add-ons, you’ll need to temporarily enable Unknown Sources. Here’s how to do it:

• Step 1: From the Kodi home screen, click the Settings icon (the cog) at the top right.
• Step 2: Select System.
• Step 3: On the left menu, click Add-ons, then toggle Unknown Sources to the right to enable it.

That’s it! Just remember to disable Unknown Sources again after you’ve installed all the add-ons you need to keep your device secure.

Which Platforms Do These Methods Work On?

Kodi’s interface is largely consistent across all platforms, with only minor variations for some devices. So whether you’re troubleshooting buffering on Windows, Android, iOS, or Amazon FireStick, these steps and fixes will work the same way.

Kodi Buffering Fix: Optimize Cache Size

Cache memory plays a crucial role in video streaming performance. It acts as temporary storage, helping your device retrieve data quickly. While caching is common in computing, video cache is especially important for smooth playback during streaming. When you stream a video online, the entire file isn’t downloaded at once. Instead, Kodi (like most apps) temporarily stores small chunks of the video in your device’s RAM. This is why a video may continue to play briefly even after your internet disconnects—the segment playing has already been cached.

To reduce Kodi buffering issues, two key steps are necessary:

1. Increase the amount of RAM allocated to Kodi’s video cache to allow more data to load ahead of time.
2. Clear out the old cache regularly so previously played videos don’t continue to take up memory space unnecessarily.

In the next sections, we’ll walk through how to adjust Kodi’s buffering settings for better cache usage and how to clear the cache properly. We’ll cover five different methods to fix Kodi buffering. Methods 1 to 4 work across all platforms, including Amazon Fire TV and FireStick. However, method 5 is not compatible with FireStick devices.

Method 1: Fix Kodi Buffering with Ares Wizard

Ares Wizard is a popular Kodi maintenance and optimization tool. One of its key features is the ability to tweak cache settings to reduce or eliminate buffering issues. Before continuing, make sure you have Ares Wizard installed on your Kodi device.

Once Ares Wizard is set up, follow these steps to optimize cache settings and improve streaming performance:

Step 1: Open Ares Wizard and select the “Tweaks” tab at the top.

Step 2: Click on “Advanced Settings Wizard.”

Before proceeding, be sure to read the caution note from the developers. Here’s a quick summary of what you need to know:

• There’s no universal cache size that works for everyone—it depends on your device’s specifications, especially available RAM.
• You can choose to store the cache in your device’s storage or RAM (RAM is strongly recommended).
• By default, Kodi uses around 60MB of RAM for video caching. If you have more available memory, you can increase this limit.

Step 3: After reviewing the info, click “Next.”

Kodi will now analyze your device’s available memory and suggest an optimal cache size—typically around one-third of your total RAM, minus a 10% buffer to leave room for background apps.

Example: If you have 900MB of free memory, one-third is 300MB. Deducting 10% (30MB) leaves 270MB for video cache—this is your ideal allocation.

Step 4: Click “Generate Settings” in the bottom-left corner.

Step 5: On the next screen, use the slider to adjust the Video Cache Size as recommended.

At the bottom of the screen, you’ll also see Buffer Modes:

• Mode 1: Buffers all online streams, including FTP and cloud sources.

• Mode 2 (Recommended): Buffers most sources, including local files.

• Mode 3: Buffers only streams from websites.

• Mode 4: Disables buffering altogether.

If you still experience buffering and have ample RAM, make sure Mode 2 is selected for the smoothest performance.

Clear Temporary Files via Ares Wizard Maintenance

If Kodi crashes frequently or slows down, it might be running out of storage—especially on low-capacity devices like older Android models.

To clean up space:

Step 1: Go to the “Maintenance” tab at the top of Ares Wizard.

You’ll see several cleaning options.

Step 2: Click the following:

• Delete Thumbnails
• Delete Packages

These two folders often consume a lot of space. In some cases, they can take up over 1GB combined. If cached files are also stored, clear them to free up additional storage. Don’t worry—this won’t erase the settings you’ve just applied in the advanced settings section.

Method 2: Fix Kodi Buffering by Using a VPN

Many Internet Service Providers (ISPs) promise fast, unlimited internet, but heavy users—especially those who stream a lot—often face bandwidth throttling. This means your ISP may slow down your internet speed after you reach a certain data limit. Depending on your country, throttling may or may not be legal, and it’s often hidden in the fine print of your service agreement, which most people overlook. If you frequently stream movies or shows on Kodi, you could be targeted as a heavy user and experience throttling. Since the repeal of net neutrality regulations in the United States, the legality and transparency of throttling have become even murkier.

Using a reliable VPN is one of the best ways to avoid ISP throttling and significantly reduce Kodi buffering problems. A VPN does more than hide your identity online—it also encrypts your data usage, so your ISP cannot see what you’re streaming or downloading, only the total amount of data transferred. Many users worldwide have reported that streaming, torrenting, and heavy file sharing often trigger ISP throttling. With a VPN, you won’t have to worry about this anymore.

Top 5 VPNs for Kodi Streaming

Here’s a list of the top VPN providers trusted by many Kodi users. Personally, I use ExpressVPN, known for its speed and reliability.

• Most VPNs offer dedicated apps that can be installed directly on your FireStick, Android TV, or other devices.
• After installation, simply connect to a server location of your choice.
• Launch Kodi with the VPN active to enjoy faster, buffer-free streaming without ISP interference.

Using a VPN not only improves your Kodi experience by preventing throttling but also enhances your privacy and security online.

Method 3: Stop Kodi Buffering Using Supreme Builds Wizard

Another effective tool for fixing Kodi buffering issues is the Supreme Builds Wizard. This popular maintenance utility helps optimize performance by tweaking Kodi’s system settings.

If you haven’t already installed Supreme Builds Wizard, start by doing that first. Then follow these steps:

1. Step 1: Launch Supreme Builds Wizard from the home screen or go to Add-ons > Program Add-ons.
2. Step 2: Click Supreme Builds Maintenance.
3. Step 3: On the next screen, select (Supreme Builds) System Tweaks/Fixes.
4. Step 4: Choose Advanced Settings.
5. Step 5: Select Quick Configure AdvancedSettings.xml.
6. Step 6: We recommend not changing the suggested settings. Just review them briefly, then click ‘Write File’ in the bottom-left corner.
7. Step 7: If a message pops up asking whether to remove an existing AdvancedSettings.xml file, click ‘Remove Settings’ to continue. This typically appears only if you’ve previously configured advanced settings.

Method 4: Use Real-Debrid to Eliminate Kodi Buffering

Even with a fast internet connection, Kodi can still suffer from buffering issues. That’s because it often struggles to utilize your full bandwidth when accessing free or overloaded streams. Real-Debrid solves this problem by providing access to a premium network of high-quality streaming links, including numerous 1080p Full HD and fast-loading sources.

What is Real-Debrid?

• It’s not an add-on itself, but rather a multihoster that works alongside Kodi add-ons like Exodus Redux, Seren, Yoda, Gaia, and many others.
• It boosts streaming performance by tapping into high-speed servers that are often underused by public add-ons.
• As an unrestricted downloader, Real-Debrid can utilize up to 80–90% of your available internet speed, supporting connections up to 300 Mbps.

Is It Free?

• Real-Debrid does offer a free tier, but it has limited stream availability and reduced speed, often only active during certain hours of the day.
• For a better experience, a premium subscription is highly recommended. It starts at around $5 per month, with discounted rates available for longer-term plans.

To unlock its full potential, consider subscribing to the premium version. Once active, Real-Debrid can virtually eliminate buffering issues by providing faster, more reliable, and higher-quality streams.

Method 5: Fix Kodi Buffering Issues Using a Custom Configuration File

If you’re still facing Kodi buffering problems after trying the previous methods, this advanced technique may help. In this method, you’ll manually create a configuration file and place it inside Kodi’s user data directory. Don’t worry—it’s easier than it sounds, and you don’t even need to open Kodi to do it.

Fixing Buffering in the Exodus Addon

Exodus is a widely used Kodi addon known for its massive content library. If you use Exodus (or similar addons), here’s how to fix buffering within the addon itself:

Clear Addon Cache

• Step 1: Go to Kodi Home Screen > Add-ons > Video Add-ons and open Exodus.
• Step 2: Scroll down and select Tools.
• Step 3: Click Clear Cache.
• Step 4: Confirm by selecting Yes.

If your addon doesn’t include a cache clearing option, use the Ares Wizard method covered earlier.

Common Reasons Kodi Streams Slowly or Buffers Frequently

Even with the best settings, buffering can occur due to:

• ISP throttling
• Limited RAM or storage space
• Overloaded or broken streaming links
• Improper cache configuration
• Slow internet speeds
• Unoptimized Kodi add-ons

By using the five methods above—especially in combination—you can significantly improve Kodi’s performance and minimize buffering on almost any platform.

Common Causes of Slow Streaming and Buffering on Kodi

Buffering during streaming can ruin your viewing experience. Kodi, while powerful and versatile, isn’t immune to these issues. Let’s explore the most common reasons behind Kodi buffering and what you can do about them.

Reason #1: Slow Internet Connection

Streaming high-quality content (like 720p or higher) requires a stable and fast internet connection. The higher the video resolution, the more data it needs to stream smoothly.

• Netflix’s minimum requirement is just 0.5 Mbps, but in practice, that’s too low for most streaming needs.
• For a better experience, especially with standard-definition content, aim for at least 5 Mbps.
• For high-definition or Ultra HD streaming, 20–30 Mbps or more is recommended.

Most ISPs now offer fast enough internet for high-quality streaming. Still, some throttle speeds based on usage. A reliable VPN can help bypass ISP throttling, giving you smoother playback on Kodi. You can test your internet speed using websites like Speedtest.net or similar services. The download speed has the biggest impact on streaming.

Tips to Boost Internet Speed for Kodi:

• Stay close to your Wi-Fi router or modem.
• Whenever possible, use a wired Ethernet connection for more stability.
• Pause or stop background downloads while streaming.
• Limit the number of devices connected to your network.

If you’ve optimized your connection and still experience issues, try one of the advanced Kodi buffering fixes mentioned earlier. Also, check with your ISP if you’re consistently receiving lower speeds than promised in your plan.

Reason #2: Overloaded Streaming Sources

Sometimes, the issue isn’t on your end. Popular streaming sources can become overcrowded when too many users try to access them simultaneously. When a server is overloaded, it may slow down, causing buffering. Many Kodi add-ons offer multiple streaming sources for the same content. If one stream is lagging, simply switch to another link—it could instantly improve your playback experience.

Final Thoughts on Kodi Buffering Fixes

Buffering remains one of the biggest challenges for Kodi users, but it’s far from unbeatable.

Key takeaways:

• Use a VPN to bypass ISP throttling and secure your connection.
• Optimize cache settings and regularly clear temporary files.
• Choose less congested streaming links when available.
• If all else fails, consider resetting Kodi to factory settings for a fresh start.

With these steps, you can significantly improve streaming performance and enjoy Kodi without annoying interruptions.

FAQs

How can I check if my Kodi buffering issue is due to overcrowded servers?

Overcrowded servers are a common but often overlooked reason for Kodi buffering. If multiple users are accessing the same streaming source simultaneously, it may struggle to deliver smooth playback. Try switching to an alternative source provided within the Kodi addon to see if the buffering improves.

Why does Kodi buffer even with a fast internet connection?

Even with high-speed internet, Kodi can buffer due to other factors like ISP throttling, underutilized bandwidth, or overloaded streaming servers. Using a VPN and optimizing your buffer settings can help ensure Kodi uses your internet speed efficiently.

Does using Ethernet instead of Wi-Fi improve Kodi streaming?

Yes, using a wired Ethernet connection can significantly improve Kodi performance. Unlike Wi-Fi, Ethernet offers a more stable and consistent internet connection, reducing the chances of lag and buffering during streaming.

What cache size should I use to reduce Kodi buffering?

The ideal cache size depends on your device’s available RAM. Typically, allocating one-third of your free RAM for cache—while leaving a 10% margin—is a safe approach. Tools like Ares Wizard or Supreme Builds Wizard can help you adjust this easily.

Can too many devices on the same network affect Kodi performance?

Yes, having multiple devices connected to the same network can slow down your internet speed, especially if they’re downloading or streaming. Disconnect unused devices or pause heavy downloads to ensure Kodi gets the bandwidth it needs.

Is Kodi buffering more common during peak internet hours?

Absolutely. Internet congestion during peak hours—when many users are online—can impact streaming quality. This is especially true if your ISP limits bandwidth during high-traffic times. Using a VPN can help avoid some of these slowdowns.
