I just got a new MBPR(this years model) and I am having trouble with the wifi. The internet drops quite a few times every day but Airport does not disconnect from the router. Nothing will load at all. The current fix is to wait for it to come back on or to disconnect and reconnect the Wifi. I have tried several fixes like resetting PRAM and SMC and creating new network configurations but nothing works. Does anybody else have this problem, could it be hardware related? None of the other devices I use disconnect at the same time so I have ruled out my router.
