Having issues getting started with the ESP8266

I've had my ESP8266s laying around for a few months waiting to find something to use it on. I just started yesterday but I'm at a loss for words with the lack of response.

I'm using my 3.3V FTDI connected as follows:

ESP8266 -> FTDI
VCC -> 3v3
RST -> 3v3
GND -> GND
TX -> RX
RX -> TX

I'm using the Arduino IDE serial window setting the baud to 115200 (I've also tried 9600) and have both NL and CR selected. I type in "AT", hit enter... and get nothing. I see the TX light blink, but nothing on the RX. I've also tried just carriage return with the same results. I've ordered new ones, but the two that I have both look different to all the pictures I see here's what mine looks like, any help is much appreciated, I have no clue where to go from here

That one look like a NRF24L01.
Take a look at the back, on mine is printed NRF24L01

ESP8266 has two chips on board.

You can find lots of info here:

Mine doesn't have anything printed on the back, but I think you're correct. Banggood sells both the NRF24L01 and ESP8266, I think they might have mixed them up. The two chips was why I posted a picture, because I hadn't seen that large 16MHz clock on any other 8266, thanks for the help, that explains an awful lot on why "AT" doesn't do anything :o

AFAIK the command has to be transferred with 9600 baud and must be terminated with CR LF (!)
