Carry out the following  checks when the iPhone dropping WiFi  randomly:

• Try your iOS device on another Network such as neighbors’ or public Hotspots (public wireless access points). If the device can connect to the network, then the problem is probably with your WiFi network;

How to fix it when WiFi keeps disconnecting on iPhone due to a network issue?

When is iPhone disconnecting from WiFi because of a network issue, then follow the steps below:

1. Ensure that your device is within the network range;

Go to Settings> WiFi > Tap the information mark (i) > Enable Auto-Join;
