I'm using nodemcu dev kit with Arduino IDE.
I was able to connect to my AP at home and sent my sensors data to cloud.
However, I'm unable to connect with my AP at the office. I HAVE changed the SSID and password in the code.
When I use the WifiScan example from Arduino 1.6.7 IDE, the nodemcu dev kit was able to find my office AP. The signal was strong. Other devices (phone, notebook, etc) can connect fine to it.
I've also tried to change the channel to AUTO, 1, 6, etc.
Anyone can guide me to the possible culprit?
Thank you.
