Soldering an external antenna on your esp8266 may solve your wifi problems.
If you can do your job on the esp without Wifi you can use an ethernet shield with a Wiznet W5500.

also check your Wi-Fi network with a diagnostic tool like INSSIDER. It's a free wifi scanner for Android/Windows so you can check the "black holes" in your Wi-Wifi network.
I tested wifi scanner with wifi analyzer on android phone. After I opened first topic.

:eek::eek:

I'm not electronic tech. I research your advice. Maybe I will solder without cable (direct anttenna) I will test.
Thank you @thetahsk[/QUOT
There should be proper Impedence matching for maximum power transfer....to increase the strength of signal....it is very difficult to do it manually....Please look for such module having inbuilt antenna system...
