Defective chip or broken software?

[qheinal]

i have 3 wemos s2 mini boards and all of them can scan for wifi networks but only 1 can connect to wifi in the three. I have tested the resistors and capacitors around the chip of the good one and measured the others and they all are the same. Is the chip just defective? because it seems like abit weird that they can find it but not connect to it.

Btw EspNow works with them....they just wont connect to WiFi from modem/router/phone hotspot. And i did infact set it 2.4 GHz with no password.
