How to Stop Kodi Buffering – a Step-by-Step Guide


If videos taking forever to buffer when you watch them on Kodi, there are two main root causes that you should investigate first.  The biggest reason for video loading problems is Kodi’s default cache settings.  If you optimize your cache settings and you’re still having issues, then Internet Service Provider (ISP) throttling may be to blame.

Recently, the FCC fined T-Mobile for illegally throttling customers that stream videos.  Experts believe that smaller ISPs could also be targeting video streamers and slowing down their connections.

Want to learn how to stop Kodi buffering problems?  If so, read on to discover the two best ways for improving video performance on Kodi and fixing Kodi issues that cause buffering.

Fix #1: Adjust your cache settings and clear your temp files

When you stream videos with Kodi, a few seconds of the video are saved either to your device’s hard drive or to its RAM.  If something happens to your internet connection, your video cache allows Kodi to keep playing the video while your device tries to reconnect to the stream.

How does cache affect Kodi video performance?

The way that Kodi stores and manages cache files can have a big impact on streaming video quality and performance.  If you have a small cache file and an unstable internet connection, you’ll definitely run into buffering issues when you try to watch streaming video.

On the other hand, an overly big cache file can also cause issues and result in Kodi not working properly.   If your cache file grows too large for your device to handle, you’ll experience sudden crashes and other erratic problems.

By default, Kodi only stores 60MB of cache.  If you have system resources to spare, you can drastically improve video performance by increasing your cache file size.

How to adjust your video cache settings on Kodi

The Ares Wizard– a free Kodi addon designed by Project Ares— contains an advanced settings menu that provides the best and easiest way to change Kodi’s default video cache settings.  The wizard automatically detects how much memory your system has available and recommends settings that’ll allow you to maximize video performance when you stream.

Here’s how to install Ares Wizard and get to its advanced settings menu:

  1. Download the latest Ares Wizard zip file to your desktop.
  2. From Kodi’s main menu, navigate to system → settings → addons → install from zip file → desktop.
  3. Select the Ares Wizard zip file, then wait for the installation success popup to appear in the lower right hand corner of the screen.
  4. Open Ares Wizard from the main menu under programs, then click the tweaks button.

Now you should be at a screen that looks like this:


If you click next and then click generate settings, Ares Wizard will automatically generate the optimal cache settings for your device.

The most important setting here is the first one from the top: video cache size.  I’m using Kodi on a Mac with a decent amount of free RAM, so Ares Wizard automatically ramped up my video cache from 60MB to 1987MB.


The second most important setting on this page is the one that’s located above the “apply these settings” button: buffer mode.  Four different buffer modes are available.

  • Mode 1.  In mode 1, Kodi buffers all internet streams including FTP streams and other rare video sources.
  • Mode 2.  In mode 2, Kodi buffers absolutely everything– even local files.
  • Mode 3.  In mode 3, Kodi only buffers streams from websites.
  • Mode 4.  Mode 4 disables buffering altogether.

If you’re using a device that has lots of memory, it makes sense to ramp up your video buffer and use mode 2– aka “buffer everything” mode.  A large buffer file allows you to preload a big section of the video stream, allowing for smoother playback and fewer interruptions.

Use the maintenance button to delete your temp files

If you’re experiencing sudden crashes when you use Kodi, you may be running out of disk space.

If you’re using Kodi with Amazon Fire TV, its 8 GB of hard drive space can fill up fast– especially if you have downloaded lots of addons.  Also, low hard drive space can be a problem for those using Kodi on Raspberry Pi.

To clear your temp files, click Ares Wizard’s maintenance button.  You should see a screen that looks like this:


Just click delete thumbnails and delete packages to finish the job.

An alternate addon you can use to maintain Kodi

In addition to Ares Wizard, there’s a different addon you can use to adjust your video playback settings: the awesome addon installer from known as Indigo.

We recommend that you download and install both Ares Wizard and Indigo.  Both addons are excellent free tools that every Kodi fan should have.

Though Indigo lacks a few of the advanced video playback tools that Ares Wizard has, you can still use it to clear your cache.  To get to Indigo’s configuration screen, open it up and click maintenance tools.

Via Indigo’s maintenance tools menu, you can reduce the size of your cache so that it won’t ever fill up your hard drive again.  Also, you can click auto maintenance to clear your cache, packages and thumbnails in one fell swoop.

Fix #2: Use a VPN to prevent your ISP from Throttling You

Instead of forking up the money to upgrade their infrastructure, some ISPs have resorted to cheap tactics to avoid network slowdowns.  In October of 2016, FCC forced T-Mobile to pay a 48 million dollar fine for throttling customers who bought the so-called “unlimited” plan.

The T-Mobile customers that that were most affected by illegal throttling were the ones that used the internet a lot– video streamers, torrenters and gamers.  Many Kodi users on T-Mobile likely found Kodi not working properly due to that throttling.

If you suspect that your ISP is penalizing you with slowdowns for using Kodi, you can prevent them from monitoring you by logging on to a Virtual Private Network (VPN) before you use the web.

What’s a VPN?

A VPN is like a two-way mirror that allows you to use the web normally, while simultaneously preventing 3rd parties (governments, ISPs, etc.) from monitoring what you’re doing.

Everything you do online leaves behind a digital footprint– unless you access the web through a VPN server.  VPN servers hide your internet activity by funneling your data through an encrypted tunnel.

What’s the best VPN for streaming videos on Kodi?

If you want to use a VPN network to stream, you’re definitely going to want to go with a VPN service that features fast servers.  Low quality VPN services slow down your internet connection.
