trying to connect an RFID reader to a website via a wifi shield

Hi Guys,

First of all I have to say im not really an experienced programmer but I am looking to try and read different RFID tags using the Adafruit PN532 NFC/RFID Controller Shield for Arduino Adafruit PN532 NFC/RFID Controller Shield for Arduino + Extras : ID 789 : $39.95 : Adafruit Industries, Unique & fun DIY electronics and kits , and display the information of the different tags on a website via an Arduino WiFi Shield. I just wasn't sure if the different boards would work together....

I have been having problems connecting sometimes to my router network with the WiFi shield. It says its connected on the Serial monitor but when I look up connected devices on my router and it isnt there... if anyone has any experience with this it would be greatly appreciated.

I am using a base Arduino uno.

Thanks alot
