Uses WiFiManager library.
It works fine with my router.
BUT, at the client, I do everything as expected (turn to Access Point, Enter credentials, save, reboot ESP) but does not send data to thingspeak.
Like if it cannot connect to the internet.
(the password is 100% correct)
My client's router is a 'Thomson' brand name router.
Does ESP face any problems connecting to some specific routers?
What can I do?
Any help is welcome.
