We do NOT guarantee that our VPN will work with your specific router.

Each router is different. The same model may be flashed with a different version of the OS, and some routers may only support older OS versions which don't work with our App.

This guide is provided on a best-effort basis. There are too many variables to write an exhaustive guide that will work with all routers.

We provide you with links to external documentation and resources. Please refer to them if you get stuck. Most likely the issue you are facing has been addressed in those guides.

We do NOT provide extensive customer support for routers.

We only support routers listed in this guide below.

We only provide support for the configuration of the Merlin Clash app:

  • Where to put the API link and how to update it.

  • How to setup DNS to prevent DNS poisoning.

  • How to connect to a specific server.

We do NOT provide ticket support for:

  • Flashing your router

  • Installing the Merlin Clash app on the router

  • Exception: If links in this guide are no longer working, you can open a ticket with us to get working links.

However, we do provide this guide in English, as well as links to other resources you can read should you need more info.

We only support Merlin-Koolshare NOT Vanilla Merlin

You'll need to flash your router with one of the firmwares in the links in this guide below.

Alright! With that out of the way, let's get started!

Buying Your Router

The Merlin Clash app for Merlin is part of the fancyss app package. It can only be run on a customized version of Merlin, Merlin-Koolshare.

Therefore, you'll need to get a router that can be flashed with Merlin-Koolshare (or that comes with it pre-installed).


  1. Purchase a router that can run Merlin-koolshare

  2. Flash it with Merlin-Koolshare

  3. Download and install the FancySS app package


Please only purchase routers listed below

Please find the supported routers list here:

If the link above doesn't work, go to and click on the highest version of "Koolcenter" (i.e. KoolCenter_梅林改版固件_386【新】)

If you don't have a router listed in the links above, please do NOT continue with the guide. It will not work.

Flashing your router

Once you've bought your router, you'll need to flash it with Merlin-Koolshare.


  1. Make sure you already have Merlin flashed on your device

  2. It is recommended to first update your Merlin firmware to the latest version from your router's manufacturer website or merlin's website before installing KoolShare.

Download the KoolShare firmware

Find which version of Fancyss your router supports from the router list above.

  1. Find your router in the list and click on it:

  2. Download the latest version of the firmware

Flash your router with KoolShare

  1. Login to your Merlin router

  2. Go to Administration > Firmware upgrade

  3. Click on "Choose file"

  4. Find your downloaded firmware and click "Upload"

Enable JFFS

Next, we need to enable JFFS to be able to upload MerlinClash to our router.

  1. Go to Administration > System

  2. Enable "Enable JFFS partition", "Format JFFS partition at next boot", and "Enable JFFS custom scripts and configs"

  3. Click "Apply" at the bottom of the page

  4. Reboot your router

Install the APP (MerlinClash)

First, you need to download the correct version of MerlinClash for your router.

You will need a telegram account to access the telegram group where the files are posted.

Join the group:

Then find the latest file for your router. You will need to know the CPU type of your router.
