With Apples recent upgrade to iOS 11.2.1, many iPhone users are experiencing issues like Wi-Fi not working. Many have asked us “Why is the Wi-Fi on my iPhone not working?” We’ll give the answer to this question in the last part of this article. But first, let us look at how to fix iPhone Wi-Fi not working.

How to Fix iPhone Wi-Fi not Working – Five Ways

There are several methods of fixing iPhone Wi-Fi not working, but we shall be looking at five distinct methods: reset Wi-Fi network, reset Wi-Fi network’s router, and completely reset iPhone, update iOS to latest version, and put iPhone in DFU mode and restore with iTunes.

#1. Reset Wi-Fi Network

Wiping out Wi-Fi network settings is a good way to restore your iPhone Wi-Fi to its default settings. This can be done using iTunes, but I would prefer if we head straight to iPhone Settings and get done with it.

Here are the necessary steps:

  • Step 1: Click Settings > General > Reset.
  • Step 2: Click Reset Network Settings.

At this point, your iPhone will erase all the Wi-Fi networks it has connected to before now. Search for available Wi-Fi networks and try connecting to one.

#2. Reset Wi-Fi Network’s Router

iPhone Wi-Fi not working isn’t always a pointer to bad iPhone network settings; the problem may be coming from the Wi-Fi network router. A hard reset is the best way to correct such problems especially when the administrator has forgotten the router password.

Once the software on the router is reset to factory default, all customizations such as passwords, ports, forwarding, security keys, and custom DNS servers will be erased.

Here are the steps to perform a hard reset:

  • Step 1: Turn on the router if it’s off.
  • Step 2: Search for the router’s reset button.
  • Step 3: Use a paperclip to hold down the reset button for 30 seconds.
  • Step 4: Wait for another 30 seconds for the router to fully reset, then turn it on.
