hi , where should i solder antena to the board?
As far as I know, you can't.
I would recommend buying a board with a connector for an external antenna. Often these boards require you to move a resistor to allow the external antenna to be used instead of the built-in/pcb antenna. For example the Wemos D1 mini Pro:
I would guess that the chip component at the top left corner of the tin can couples to the antenna from the Wi-Fi transceiver. However it isn't as straighforward as just breaking the link and soldering a bit of wire. At 2.4GHz you need RF coax with a good ground connection close to the "live" antenna connection. It's easy to lose more signal in your coax than you gain from using a better antenna at the end. I agree that a module that already has a coax connector on the board is a better bet.
Hi,
see if these tutorials helps.

A column in a current ham radio magazine reminded of an easy fix for your range problem. Add a counterpoise to the circuit board ground furthest away from the antenna. That will be a 1/4 wavelength of flexible wire soldered to a ground trace somewhere furthest from the antenna.
You can trim the wire length a bit at a time and test the distance you are getting.
Your circuit board antenna is really just 1/2 of an antenna. The designer assumed the rest of the board and your connecting wiring will make up the other 1/2 of the antenna. By adding the wire, you are assuring there other half is actually there!
you can't. buy a version with an external antenna connector
You need the D1 Mini Pro, and an antenna with the right connector.
Is it the same subject?
Post repetition is not recommended on the forum.
Your two topics on the same or similar subject have been merged.
I note that you were warned here How to connect esp8266 to batteries and switch about duplicate topics, a warning you seem to have ignored. I have stopped you posting for 2 days, if you continue to ignore the forum rules you will get a longer ban or a permanent suspension.
I note all your topics are of a similar nature: 'How do I connect this or that to something or other'. These are trivial questions and don't seem to be related to any particular project or learning objective. Please stop asking questions like this and ask something substantive in relation to whatever your project is or you are trying to learn. Again, you are risking a permanent suspension from the forum.
Thank you.
