Arduino uno not working with Arduino Wi-Fi Shield

I have connected my Uno (freeduino USB 1.1) to a wifi shield , but on conecting the wifi shield and uploading sketch on it , program doesn’t load on it and i get

avrdude: stk500_getsync(): not in sync: resp=0x00

as error,

I also tried uploading the sketch (any sketch, for instance simple blink sketch ) on arduino due stacked up with wifi shield but then i get

Device not found on COM 8

I’m also unable to reset my board when wifi shield s plugged on. please help

This is the shield i’m using , the arduino’s official wifi shield

Please see that otherwise the program uploads on the board and runs perfectly when the shield is not connected

I have exactly the same problem and was wondering if you have got it working?
