Weak wifi signal/range

[Nicodomo]

Hello, 

Glad to join the forum, there are a lot of interesting things here.

I just received my Kincony A16v3 board equipped with the display. I planned to run it directly under ESPHome. 
I flashed my YAML file, but upon reboot, it wouldn't get an IP address. I finally found the issue: it worked when I placed it right next to the Wi-Fi router. 

At best, I get a signal at 2.4 meters away. It's as if the built-in antenna isn't working. Is this normal? 

What kind of performance/behavior are you experiencing?

Thanks for your answers!

do you have connect a IPEX wifi antenna?
another way, you can download KCS v3 firmware for a testing.
