I used the Explore Scientific PMC-Eight® Application Note PMC8-AN002 pdf. In putty i used the $$$ to access commands and used the factory RESET command.
Hi Filippo,

Yes, I suspected as much.

You performed the section entitled: 
"If you want to change the PMC-Eight WiFi RN-131 configuration then perform the following procedure:"

Unfortunately, you did not heed the warning in this section:
NOTE: Please refer to the Microchip WiFly Command Reference Manual located here:
CAUTION: You change these parameters at your own risk,

The section you wanted was entitled:
"If you want to change the interface from the default WiFi Port (interface 1) to the Serial Port (interface 0), do the following:"

What you did was perform a "Microchip" Factory Reset which returned the RN-131 module to the Microchip Factory default configuration. This configuration is set before we at Explore Scientific set OUR SPECIFIC PMC-Eight configuration settings.

Here is what you need to do to recover and get back to the "Explore Scientific" Factory Default:
(This is an excerpt from the Application Note AN002 which is included on pages xx in the PMC-Eight Programmer's Reference located here:

Please refer to the Microchip WiFly Command Reference Manual located here:  for details about the following instructions
You must use the values in the Microchip manual for the "Microchip" default configuration values to attach to the RN-131 network SSID and telnet into the proper IP address with the proper port number. See the section in the Microchip RN-131 manual entitled: FACTORY RESET.

1. Connect your computer to the wireless network SSID of the Microchip SSID, whichever yours is. It may include the word "roving" or "wifly"
2. After connecting to the Microchip SSID, open up a Command Window and issue the command "ipconfig /all"
3. Look for the "Wireless Gateway value" under the "Wireless LAN Adapter WiFi" section. Record this value
4. Using Putty, TELNET into the IP address recorded in step 3 using port 2000 
3. You should be greeted with the *HELLO* prompt of the RN-131 module.
4. Enter "$$$", and you should see "CMD".
5. Hit Enter again and the version number prompt, i.e., "<4.41>", is displayed.
6. Enter "get everything" to obtain a list of all the current parameters and what they are set to:

At this point please post these parameters here on this thread so that I can see them.


RN-131 WiFi Module Explore Scientific Default Configuration Setup Commands 
NOTE: It is suggested that you cut and paste each block of commands into the terminal and then manually type and enter the “save” command. Ensure you receive the “AOK” response after each command is entered. 

START OF SETUP COMMANDS --------------------------------------------------

set uart b 115200
set comm size 64
set dns addr
set dns backup

set dns name dns1
set ftp addr
set ftp time 200 save
set ip dhcp 4
set ip flag 0x47
set ip gate

NOTE: In the following 2 set commands, set the SSID to your specific module SSID, replacing the XX with your number.
             We use the last 2 characters of the MAC address 

set wlan ssid PMC-Eight-XX
set apmode ssid PMC-Eight-XX

set opt deviceid PMC-Eight save
set wlan passphrase PMC-Eight
set apmode passphrase PMC-Eight

set wlan ext_antenna 1


END OF SETUP COMMANDS -------------------------------------------------

Hopefully if you can follow all that, then you should be successful restoring your PMC-Eight. 
Alternatively, you can return your PMC-Eight controller to us to restore the system.
