Some of the users who when upgraded to iOS 7 version, including the latest 7.0.3, faced some issues with WiFi. This problem has been previously faced with Apple updates and usually Apple cures such issues with the next software updates. Till Apple does that, and God knows how many errors will we find in the beautiful iOS 7, here are a few fix-ups to help out!

2- Reset network settings:
Resetting network helps in some 60 - 70% of cases suffering from iPhone WiFi issues. Go to Settings > General > scroll down to Reset, and then tap on Reset Network Settings. If you are on a secure network, it will ask you pass keys.
3- Check router:
Perhaps the issue is not with your iOS 7 updated device, but your internet connection? Before proceeding to the next fix, make sure your network is working fine and so is the router / modem. Try same network on your other devices to ensure that it is working fine.
