What port was added when you installed the USB module on the PC? That is the port you need to choose. Don't use auto, all it did for me on auto was cause the program to hang.

Select the correct COM port (only you will know this) and search. When it finds one it'll probably give an error about reading the data, ignore that. Then set up the details, modify, reboot the module and it should auto connect.

I plugged it into a different USB port and it told me COM7. So I chose that on the configuration and still nothing. I get a message when I click search that says: Cannot find the device. The possible reasons are as follows: Com is invalid, device is not connected.

The red D2 light is on, yellow D1 is on, and Green D3 light is on on the USB board.

Have you wired it up correctly? Try swapping Rx and Tx over on one of the 2 boards

What are the lights on the WiFi module doing?

Yes, I have RX-TX and vice versa on the wifi module. On the wifi module itself no lights. but on the USB one those three lights are on. Do I need to have power plugged into the 3.3V, ground, and 5V on the USB board?

You need to have the jumper set to either 3.3 or 5v. the jumper connect either the 3.3 or 5v pin to the centre pin.

Put it on 3.3

When the unit is shipped, the 5v or 3.3v jumper is connected to the TxRx pins and must be removed and reconnected to the 3.3v side of the power option pins. All 4 leads between the WiFi board and the USB/ttl board should run straight with no turnovers.

Oh okay thank you! Sorry, I just assumed it wasn't necessary since it was plugged into my laptop I do not have the jumper wires, I'll try to go by radio shack in the morning and let you know. If radioshack doesnt have them I'll rig something up with what I have.
