iPhone 5s running iOS 7.0.2 wifi not working

Wi-fi worked great running iOS 7.0.0 and 7.0.1 but after updating to 7.0.2 I can't connect to the internet through wi-fi. The phone shows that it is connected to the network and obtains an IP address from the router. I have verified, using my laptop, that my router and internet connection are working. I've tried turning wi-fi off and back on, I've tried having it forget the network and then re-connecting, and I've tried power-cycling the phone, but none of these have worked.

Anyone having the same problem?
