Help for Devices

1. How do I connect to the Internet?

1.1  How can I use the App to set up the router?

Step 1:  Log into the Mercku App and connect your phone to the Mercku Wi-Fi

Step 2:  If there are already bounded routers with your account, click “Add a router” in the router list located in the top of the App homepage. Otherwise, the app will show you the page to add a new router. Then, click on “Connected already” and set up the router Wi-Fi details (Wi-Fi name, Wi-Fi password and router admin password) and internet information.

Step 3:  After the router is setup successfully, please reconnect to the Wi-Fi and return to the App.

Step 4:  Click “Connected already” on “Connect to Wi-Fi” page, enter the admin password and click “Bind”.


Potential Issue:

If, when clicking on “Connected already”, the following pop-up message arises:  “Please connect to Mercku Wi-Fi and try again”, select “Go to connect” and find Mercku Wi-Fi in the Wi-Fi list. Connect, return to the APP, and try again.

The cause behind this is because there are too many other Wi-Fi, sometimes you haven't connect to our Wi-Fi so the situation will occur. Our App is designed exclusively for Mercku Wi-Fi and can only be used under Mercku Wi-Fi.

1.2  Can I use the router without using the APP?

Step 1:  Connect your computer to the router either with Ethernet cable or Wi-Fi, access in your browser. 

Step 2:  You can set up admin password, Wi-Fi name, Wi-Fi password as well as other configurations for the router on the webpage. 

Step 3:  After configured successfully, the router indicator light will flash in green. Now you can reconnect to the Wi-Fi to get access to the internet and manage the router with Mercku  App. 


1.3  How do I set up a Hive System (router with Bee nodes)?

Step 1:  Set up the Mercku main router and connect to the Internet. 

Step 2:  Place the Bee in a suitable location and power it on, then wait for the mesh network to form automatically. The Bee indicator light will be green once the network is connected.


  • If the indicator light of Bee is blinking in green, this indicates its position is not suitable. Move the Bee to another location to gain better performance.
  • To ensure that the mesh network works properly, please place the router in an open location. The upper limit of the distance between nodes is 2 rooms or 10 meters. 

2. What is Mercku Wi-Fi

2.1  What is the master router (gateway)?

Master router is the Wi-Fi router that connects to the Internet with the ethernet cable to its WAN port. There could be only one master router in a mesh network. 

2.2  Can M2 act as a Bee?

Yes. An M2 can be used as a master router or as a mesh node. In the latter, please refer to 2.3 for the steps to add an M2 to a mesh network. 

2.3  How do I add a new M2/Bee to an existing mesh network?

Step 1: Open the Mercku APP and click “+” on the “My Wi-Fi” page.

Step 2: Power on the M2/Bee and click the M2/Bee reset button. When the indicator light blinks red, click “next” on the APP. Select the proper device in the list, click "next" and wait until it has been added to the mesh network.

Step 3: If the new M2/Bee is added to the mesh successfully, its indicator light will be green.

7. My speed test from the internet to the router is low

Step 1: Please confirm your ISP’s speed

  • It’s normal for 40% speed loss between the speed of ISP’s and the speed tested’s due to multiple interferences in the real environment 
  • If there is a huge difference between the two, please continue to step 2

Step 2: Please test your speed at and compare the result with our App result

  • If the speed test result is close to ours: please check if the results close to the speed you pay for with your ISP, if the speeds are low, you should try calling your ISP to make sure you’re receiving the right speed package or making sure they’re not experiencing an issue on their end.
  • If the speed test result is really different to ours: the speed test servers of ours are currently located in North America and China, the location of yours is too far to get great speed test result, please tell us your location, we will consider adding servers in the future.
