Why is my Kodi buffering?
There are a few reasons why you might experience find your Kodi lagging.The main ones are:
- Slow connection speed
- Network connectivity problems
- Limited bandwidth from the streaming source
- Network congestion at the source
- Unsuitable Kodi cache settings
- Internet service provider (ISP) throttling connection speeds

Slow connection speed
Streaming content requires a sturdy internet connection. Netflix makes the following recommendations for streaming their content:
- Minimum required speed – 0.5 Megabits per second
- Recommended broadband connection speed – 1.5 Megabits per second
- Speed recommended for SD quality content – 3.0 Megabits per second
- Speed recommended for HD quality content – 5.0 Megabits per second
- Speed recommended for Ultra HD quality content – 25 Megabits per second
This can be used as a general guideline for streaming content from other sources as well. Please note that if large numbers of people are accessing a single streaming source at the same time, this will create a bottleneck. This will result in increased buffering regardless of what you do.
With that being said, it’s probably a good idea to have at least a 5.0Mb/s connection to stream content through Kodi. Going a little higher wouldn’t hurt either, as this would give you a little leeway in case of any fluctuations in connection speed.
If you have a connection speed lower than this, then it is fair to expect some interruptions when streaming HD content.
Network connectivity problems
If your connection speed matches or exceeds 5.0Mbps second and you are still experiencing issues, then your first step should be running an internet speed test to see what your numbers look like. If the speed reported by the linked testing service above reports a value lower than what is expected, then consider these solutions:
- You may need to move your device closer to your wireless router if you are using a wireless internet connection. The further away you are, the more likely you are to lose signal integrity.
- You might also want to consider using a wired connection instead. A wired connection will eliminate any issues with low signal integrity due to being too far away from your router. The connection will also be faster. However, your setup will be tethered to one location with this option.
- Verify that you don’t have any other devices connected to your network that are eating up your bandwidth. If this is the case, disconnect these so that Kodi isn’t hindered.
Assuming that your buffering issues aren’t simply because of shoddy service from your internet provider, the information below might help.
Fix 1: How to change Kodi video cache settings
Instead of downloading an entire video file, when streaming, a portion of the video you want to watch is stored in an intermediate storage location called a cache. If your internet connection were to drop out for some reason, a streaming video will only freeze after the portion of video stored in the cache is played from beginning to end. If you’ve ever paused a video to let it buffer, only to realize that only a few seconds of video will load at a time, then your cache might be too small.
In order to play a video from beginning to end without buffering, the portion of video stored in the cache must always stay ahead of the portion of video played back already. By increasing the size of the cache, the maximum size of which is determined by your device’s RAM, you can buffer more video ahead of time.
Luckily, with Kodi, you can optimize your cache settings in an effort to rectify any buffering issues.
However, it should be noted that:
- Too large of a buffer file may put a strain on your device resources.
- Too small of a buffer file may make it difficult to load enough video for smooth playback, especially with slower or unstable internet connections.
We will explore how you can optimize your cache settings with an add-on called Ares Wizard.
Optimize cache settings with Ares Wizard or Supreme Builds Wizard
Ares Wizard installation
Before getting started, Ares Wizard needs to be installed. Check out our longer guide and walkthrough on Ares Wizard, or follow these installation instructions:
- Add “http://ares-repo.eu/” to sources in File Manager. Name the source whatever you want.
- Navigate to Add-ons>Add-on browser>Install from zip file and open the folder named after the source.
- Open repository.aresproject.
- Select repository.aresproject.zip and wait for the “Add-on installed” notification before continuing.
- Now, in Add-ons>Install from repository, select Ares Project, followed by Program add-ons.
- Select Ares Wizard and then Install. Wait for the “Add-on installed” notification before continuing.
- In Add-ons>Program add-ons, open Ares Wizard to get started.
How to Optimize Settings
In order to tweak your cache settings with Ares Wizard, within the program select Tweaks, followed by Advanced Settings Wizard and follow the prompts and advice provided. The Ares Wizard informs users of the following points:
- Ideal cache settings depend on the device Kodi is running on.
- Most of the time, the ideal cache location is your device’s RAM.
- Kodi uses 60MB of RAM by default.
- If your device has a lot more RAM available than this, the size can be increased. Increase the setpoint too high, however, and you run the risk of making Kodi crash.
Clicking Next in Advanced Settings Wizard will guide you through the generation of custom settings for your device.
In my case, the recommended cache size is 500MB. This will of course vary depending on the amount of available RAM your device has. Hit Generate Settings in order to review the recommended settings.
Select Apply these settings and restart Kodi in order to implement the changes.
Supreme Builds Wizard
Fixing your video cache XML file follows mostly the same process when using the Supreme Builds Wizard. The Supreme Builds Wizard requires different installation instructions, however.
To install the Wizard, follow these instructions:
- Go to your File Manager. Add the following as a source: http://repo.supremebuilds.com/ . Name it “Supreme Builds”.
- Return to your Kodi home screen go to Addons
- From there, click on the box/package symbol on the top left of the screen
- Go to Install from zip
- Locate your Supreme Builds HTTP connection and click on it
- Click on the repository.supremebuilds zip file
- Return to the screen where you found Install from zip and click on Install from repository
- Locate and click on Supreme Builds Repository
- Click on Program Addons
- Click on Supreme Builds Wizard, then click on Install
With Supreme Builds installed, do the following:
- Open Supreme Builds Wizard
- Ignore the popups by hitting Esc on your computer or canceling out of them
- Click on Supreme Builds Maintenance
- From there, click on System Tweaks/Fixes
- Next, click on Advanced Settings
- Then, click on Quick Configure AdvancedSettings.xml
- Accept all of the recommendations and click on Write File
- If you already have an AdvancedSettings.xml file, it will ask if you want to overwrite it. Otherwise, the file will be automatically created for you
Fix 3: Adjust your HQ scaler
This is a fix, not so much for buffering, but for something that can appear to be buffering: video stuttering and frame dropping.
In Kodi, you may experience video stuttering and frame dropping due to the way Kodi automatically scales up lower quality video streams into higher-quality video. This is done through a process known as video scaling.
To change your HQ scaling, do the following:
- In the main Kodi menu, click on the Settings gear symbol (top left)
- Click on Player Settings
- At the bottom gear symbol, make sure your your settings option is set to Expert
- On the right, under Processing, find “Enable HQ scalers for scaling above”. By default, this is set to 20%. However, you can lower this down to reduce the amount of scaling that occurs. We recommend reducing to 10% first and checking for how that impacts stuttering and frame dropping. If you notice no fix, reduce it lower to 0%
It’s important to remember that video upscaling improves video quality for lower quality streams. If you want your 720p or lower video streams to appear in higher quality, you’ll need to have the HQ scaler set to a certain percentage, with 20% being the optimal setting.
You may also want to try to turn off Hardware Acceleration, which you’ll find just below the HQ scalers option in the settings screen. The Direct X accelerator will push the some of the video decoding process from the CPU to the GPU. Toggling this on and off may make a positive impact on your stuttering or frame rate drops.
Note also that adjusting this downward is only important for those with lower-powered systems. Those with higher powered systems may not need to worry about this adjustment, as you may not notice any stuttering or frame rate drops at all.
Fix 3: Use a VPN to prevent ISP throttling
VPNs encrypt your internet traffic and reroute it through a server in a location of your choice. Streaming sources from Kodi add-ons may not be sanctioned by your internet service provider. If this is the case, your ISP might try to throttle your connection when you stream through an application such as Kodi. They may even go as far as disabling your connection or may send a threatening legal letter!
In order to prevent this, most Kodi users will use a suitable VPN service. Tunneling traffic through a VPN will only allow your ISP to see that some amount of data is being downloaded from a server, but not the contents of that data or source of that traffic. Note that VPNs also allow you to access geo-restricted content and protect your online privacy.
Unfortunately, many VPNs don’t meet all of the requirements Kodi users will be looking for so choose carefully. Streaming requires a large amount of bandwidth in most cases, so a reliable, fast and secure VPN provider is essential. Free VPNs have data caps or insufficient speeds as do a number of paid services. Some VPNs keep logs of user activity and should be avoided, others don’t allow torrenting. We recommend IPVanish, which provides the necessary sturdy connection, plentiful capacity, and a high level of privacy protection. It keeps no logs, is one of the fastest VPNs we have tested and works with all Kodi add-ons. It is also a relatively easy VPN to install on streaming devices like the Fire Stick and is very popular with the Kodi community.
DEAL ALERT: You can save 60% on an IPVanish annual plan here, there is a 7 day money-back guarantee so you can try it risk free and cancel if you don’t want to keep it or if it doesn’t fix your buffering nightmare. We’ve rounded up a wider selection of recommended Kodi VPNs here if you want to try a different option.

Additional Option: Kodi lagging issues may require new equipment
If you’re seeing significant buffering and generally slow speeds when using Kodi, you might be dealing with hardware issues. If you’re running Kodi on some devices with a build or a load of addons, all of those could be slowing down your experience running Kodi and even causing your Kodi streams to load up and play slower.
One solution is to invest in new and/or better equipment that you use solely for Kodi streaming. Additionally, you may want to consider Kodi forks, such as OSMC or LibreELEC, which often work better on certain devices.
For example, a Raspberry Pi 3 running OSMC is often said to offer the best streaming experience for Kodi, with less lagging and buffering issues. Others point to the Nvidia Shield as the best Kodi streaming device, as it runs solidly on the Android operating system and has a massive amount of processing power as its built to handle hardcore online gaming and graphics rendering.
In the U.S.? Expect more Kodi buffering issues in the future
If you’re in the United States, your Kodi buffering woes may only get worse in the future. The current FCC repealed 2015 Net Neutrality rules, making it possible for ISPs to discriminate against different sites based on the type of content passing through their network. Given streaming data is more bandwidth intensive, ISPs are eager to either limit these services or charge those sites for more access to their bandwidth.
Additionally, the FCC is considering lowering the definition of broadband in the U.S. to 10 Mbps, down from 25 Mbps. What does this mean for you? That your ISP may see little incentive to improve its network and provide more bandwidth.
The only effective way to keep your ISP from throttling data is to utilize a VPN.
