- Wed Jan 07, 2015 11:47 am #6576 That's a good hint. My router's lease time is 24 hours, and I can confirm the module re-lease ip address every 5 minutes *sharp*. Would it be the ESP internal timer problem?

@Baoshi , it seems that your disconnection to router is because that you do nothing since connected to router...
Please try to ping ESP8266 from PC, and see if it still disconnect from router.. PC -> Router -> ESP8266 , try ping
