Xiaomi MI Box (MDZ-16-AB) doesn't have an antenna. You can add one easily.

I have two Mi Boxes. Both have lousy WiFi reception. I finally decided to open one up and see if I could re-position the antenna or replace it. To my surprise, there was no antenna. I opened my other Mi Box and it didn't have an antenna either. There is a little plug for the antenna, but the antenna itself is missing.

The antenna plug is the same one found in most laptops and WiFi cards, variously called an IPX, IPEX, or U.FL plug. You can buy antennas with this plug on ebay or Amazon for about $2. They come as little flags you can stick down or little pcb boards which can have 5dbi or more gain.

I got a couple of 8dbi gain pcb antennas. The can be positioned inside the Mi Box case, but I drilled a small hole and ran them outside where they are clear of the electronics and big steel heatsink and can be aimed at the router. No soldering, just open the Mi Box, take out the four screws that hold the motherboard. Slowly pull off the motherboard which is stuck to the heatsink, and then plug in the antenna. Simple.

My WiFi download speed has almost tripled from less than 10mbs to almost 30mbs. I get 20mbs even through my VPN. I now can stream 1080 HD movies on Netflix without stuttering or buffering.

Spend $2 and 15 minutes work and you won't hate your Mi Box anymore.

Make sure the antenna will do 5ghz
I almost forgot, make sure you get an antenna that will work for both 2.4ghz and 5ghz.

Yeah, it can be tough to open. There're no screws or anything, just the clips all around the edge. I started with a sharp knife to open a crack and then slid in a credit card and ran that around the edge to release the clips. One of those plastic thingies to open cell phones works even better than a credit card.

Hi.
I have two MiBox and the connector is not the standard that is used for antennas. It is a Hirose MS-156C, usually used as a test point, so it is not possible to connect antennas with an IPEX connector.
Can you detail how you did it?
Thank you.
