iOS 7.0.4 has destroyed my WiFi connectivity.
Ever since I updated my iPhone 5 with the 7.0.4 version, I can no longer use WiFi anywhere. Not even on my home router which I've been connected to for over 3 years. I have reset the phone, restored from iTunes backup, restarted the router etc etc. Nothing works.
