Disappearing wireless conector on M2N32 590

Hi, I have a asus M2N32 deluxe sli 590 board, and ocassionally, say one
third of the time, my computer cant detect it, the wifi program loads but
says it's been diabled! I turn on and off a few times and wiggle my antenna
socket and it works again (after a while).

Any ideas??

Thanks
