I am having trouble with progrramming my Arduino atmega168 serial.
when i am trying to program, it shows

avrdude: stk500_getsync(): not in sync: resp=0*00
avrdude: stk500_disable(): protocol error, expect=0*14, resp=0*51

what we have to do...???
we are in the middle of our project, wifi robot, and when our wifi router is connected to arduino, the receiver led glows permanently and no expected output is obtained..
please help us as soon as possible...


First thing todo is check under the tools menu if you have the right board selected

I can't tell from your description if you are saying you have the arduino serial board, or if you have an arduino clone connected via serial.

If it's not a "real" arduino board (i.e. RBBB or other breadboard type) you may need to use the reset button when uploading, or connect RTS from your serial port to reset on the arduino through a .1uF capacitor.

If it's the arduino serial board, you will need to use the Reset button, or you can do this hack to enable auto-reset http://arduino.cc/blog/2007/09/07/enabling-auto-reset-on-the-arduino-ng-and-serial-boards/
