On your iPhone, go to Settings > General > Reset and select Reset Network Settings.
This will erase all wi-fi network settings from your iPhone and will require re-joining every wi-fi network you have access to and previously connected your iPhone with before when returning within range of such a wi-fi network.
If no change after this, try restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup.
If no change after this, your iPhone has a hardware problem likely with the wireless card.
