1. Does your router encrypt as WPA2 ?

2. maybe you could try the simplest code as http://bbs.espressif.com/viewtopic.php?f=10&t=144 whether it can connect to router succeed。

Yes, I believe so. Here's the output from

Code: Select alliwlist wlan0 scanning

:

I've flashed that code onto the chip but I'm not able to ping it. I guess I can add some code to init UART and see what else is going wrong there.

- Sat Feb 28, 2015 1:28 am #10955 With UART enabled and the code from http://bbs.espressif.com/viewtopic.php?f=10&t=144, I have similar observations. I see wifi_station_get_connect_status() returning STATION_CONNECTING for a while and then it returns STATION_WRONG_PASSWORD. Finally, after a while, the wifi_station_get_connect_status() returns STATION_GOT_IP.

I just don't understand why it takes so long to connect to the wifi network. How long does it take for the folks here to connect to a wifi network?

Not that long。。 usually got ip in 2 seconds..
