Follow these steps to troubleshoot the above issues:

1. Be sure you're in range of your Wi-Fi router (access point).
2. Tap Settings > Wi-Fi and turn Wi-Fi off and on. If your Wi-Fi setting is dimmed, follow these steps.
3. Confirm that your Wi-Fi router and cable or DSL modem are connected to power, turned on, and connected to the Internet. If not, refer to your network administrator or Internet service provider (ISP) for assistance
4. Restart your iOS device.
5. Tap Settings > Wi-Fi and locate the Wi-Fi network to which you're connected.
6. Tap and Forget this Network.
7. Try to connect to your desired Wi-Fi network.
8. Note: You may need to enter your Wi-Fi password again if your network requires one.
9. Turn your Wi-Fi router off and on2. If your ISP also provides cable or phone service, check with them before attempting this step to avoid interruption of service.
10. Update your device to the latest version of software.
11. Update your Wi-Fi router to the latest firmware2. For AirPort Base Stations, install updates using the AirPort Utility.

Wi-Fi disconnects or signal strength is less than expected

1. Move closer to the Wi-Fi router (access point).
2. Check for sources of potential interference.
3. Remove any case, stand, or other accessories from your iOS device and see if signal strength improves.
4. Reset network settings by tapping Settings > General > Reset > Reset Network Settings. Note: This will reset all network settings including
• previously connected Wi-Fi networks and passwords
• recently used Bluetooth accessories

VPN and APN settings

Additional Information

• Find information on connecting to a Wi-Fi network.
• Some third-party routers may not be compatible with all iOS devices, even after updating to the latest firmware. If your iOS devices can successfully connect to other Wi-Fi networks, contact your router's manufacturer to ensure that your router is compatible with your iOS device.
• See recommended settings for configuring your Wi-Fi router for use with iOS devices.

My iPhone seems to be dropping wi-fi connectivity overnight, leading to cellular data usage. The phone will be plugged in and connected to wi-fi when I go to bed and connected to the wi-fi when I wake up.

Is there any way to ensure that the connection to the wi-fi doesn't drop?

How do you know the phone is using cellular data overnight? If it is based on the timestamp of entries on your carrier's web site that is not a good indication, because the timestamp on your cellular bill is the time accumulated usage was posted to your account in the billing system, not the time the data usage actually occurred.

The only way to be sure is to note the cellular usage before you go to bed at settings/cellular and again in the morning (you may want to take screen shots.). There may be a small amount of cellular data used, because some of the phone's functions only work on cellular data (visual voicemail, MMS messaging, network sync, etc), but this usage should only be a few kb. If it is more than that also note the amount of data used by each app at settings/cellular for help in troubleshooting.
