I’ve been trying to connect to my router using an ESP8266 using the command AT+CWJAP=”ssid”,”password” or AT+CWJAP_DEF=”ssid”,”password” and all I get is “ERROR”. My router is configured as “WPA_PSK”. I understand that the “preshared key” is not the same as a password. However, I can’t see how I would use a password when I can only configure my router using a PSK and the ESP8266 needs a “password”. I’ve tried two different ESP8266 modules and checked the power supply. If I do an “AP+CWLAP” command, it lists the access points in my area and mine is only a couple feet away.

The problem was fixed by tying up the RESET pin to 3.3v through a resistor. Apparently being floated was causing it to drop when a high current condition existed when trying to connect to the router.
