Why does my iPhone keep disconnecting from WiFi – the possible causes

If your iPhone WiFi keeps disconnecting, in most cases the issue results from problems either on your WiFi network or on your device itself. Nevertheless, the causes may differ from case to case. Therefore, first you need to check which one of the above causes may be responsible when you find your iPhone WiFi not working without any apparent reasons.

Carry out the following  checks if your iPhone randomly disconnects from WiFi:

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

Once you know – why does my iPhone keep disconnecting from WiFi, follow the steps below to fix the issue.

How to fix if iPhone keeps disconnecting from WiFi due to network issue

If your iPhone keeps disconnecting from WiFi  because of network issue, then follow the steps below:

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

2. Check your router’s manual whether the router is working properly. Routers have a set of lights that indicate problems, if any, in it;

3. If your Router doesn’t work properly, reboot the router. This process is often referred to as Power Cycle. To do this,

Turn off your router by pressing the power button and then unplug it from the power source for about a minute or so. Plug it back again and wait for the router to complete the reboot process.

Now check whether your WiFi keeps disconnecting on iPhone after the above rebooting. If you still find your iPhone not connecting to WiFi even after rebooting, then follow the following steps one by one;

4. Update the Router Firmware and then reboot. Go to your manufacturer’s support website for the latest firmware;

5. Neighbours’ WiFi networks can interfere with yours if they use the same frequency. Try different wireless frequencies if available on your router (2.4 GHz and 5 GHz) and different bandwidths (20 MHz recommended for the 2.4 band);

6. Change wireless channels. Channels 1, 6 or 11 are recommended for the 2.4 GHz frequency because they don’t overlap with others;

7. Enable Auto-Join feature if it is disabled. If Auto-join is not enabled your iPhone may disconnect from your WiFi network frequently. Therefore, you should enable this feature if it is disabled. To do so,

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

8. If your iPhone disconnects from WiFi frequently, updating the address information of your network may sometimes solve the issue. You can, therefore, give it a try by following the steps below:

Go to Settings> WiFi > Tap the information mark (i) > Tap Renew Lease;
