Mango connection problem

I have just purchased and installed a GL-MT200N-v2 mini router. I can connect, but the connection continually drops. It drops approximately 10-15 seconds after connecting. It stays dropped and tries to reconnect for about the same amount of time. After re-connecting, it then repeats the process.
This mini router is being used to wirelessly connect my laptop to a mini computer in areas with no internet connection. I have my mini computer plugged in via ethernet cable to the LAN port.

Hi,

  1. Does the connection problem of MT300Nv2 mean that the repeater is disconnected?

  2. Let's clarify the topology again, is it right?
    Laptop (hotspot) --- (repeater) MT300Nv2 (LAN) --- MiniPC

  3. Please share the issue syslog with us.

This is all fairly new to me, but I'll try to explain. Nothing is connected to the internet. I am trying to control my mini computer using my laptop and RDP. The Mango is connected directly to the mini computer via an ethernet cable. I connect my laptop wirelessly to the Mango and log into my mini computer. I can perform a few tasks using the laptop through RDP accessing software on the mini computer. Then the software freezes for about 10 seconds and then I get the message that the connection is lost. After about 5 seconds, it reconnects. I perform a few more tasks and the process repeats
I bought a GL-AR300M-16 last year for a different mini computer using the same configuration, and it worked right away so I'm unfamiliar with the mini router's setup process. Making things difficult is the fact that I don't have any internet connected (I'm guessing to the WAN port on the Mango). Also, when I'm connected to the Mango with the laptop, I lose my wireless internet connection for the laptop.
My next step was going to be to add in a wired connection from my home router to the laptop so that Ican access the internet while still being connected to the Mango. I might also need to connect the Mango to my home router via the WAN port. I still, however need to understand the setup process better.

Picked up a GL-AR300M (with the antenna), and it works perfectly for my application.
I will save the Mango for something else.
