Arduino Uno wifi problems connecting to computer

I recently bought one of these: Geekcreit uno+wifi r3 atmega328p+esp8266 32mb memory usb-ttl ch340g module Sale - from bangood, I don't think its the conventional Arduino Uno wifi. The computer port comes up, and the on line shines but whenever I try to upload anything there is an error. I have tried setting the board as Arduino wifi rev 2 but it still won't connect. any suggestions?
