What you can do if your iPhone won’t connect to WiFi

In this article, I cover some things that should help if your iPhone won’t connect to WiFi. I will first cover a few basic things about using WiFi on your iPhone, then I will dive into the fixes.

Why it is important to use WiFi instead of your cellular data plan on your iPhone

With all of the things that we do online, having working WiFi on your iPhone is a necessity these days. If your iPhone won’t connect to WiFi you could be getting some serious data overage charges from your wireless provider. Of course, this does depend on your provider, data plan and how much data you actually use each month.

There are a few reasons that you should connect to WiFi instead of using your cellular data

  • Avoid Data Overage Charges from your Cellular Carrier
  • WiFi usually offers faster speeds than cellular
  • Cellular coverage can be limited in some areas

Have you ever gotten a big surprise bill from your cellular company?

In the past, I had a monthly bill that was hundreds of dollars more than usual. This was because one of our phones wasn’t connected to WiFi at home and it was using more cellular data than we had on our plan. After I made sure that all of our phones were connected to our WiFi our bill returned to normal the next month.

Usually, WiFi offers Faster Speeds

Even though cellular networks have greatly improved over the years, most home WiFi networks offer much faster speeds. This is important because the speed of your wireless internet connection will affect how well everything works for you. Normally the speed available from the main cellular carriers is sufficient for normal use, but that relies on you having great coverage inside of your home.

Use WiFi if your Cellular Coverage is Poor at Home

I have set up many WiFi networks for customers who don’t have good cellular coverage in their home or office. WiFi is a great solution if this is also a problem for you.

Reasons that your iPhone won’t connect to WiFi

There are many reasons why your iPhone might have a problem connecting to WiFi. The issue could be software or hardware related but this article will help you figure out how to fix the WiFi connection on your iPhone. Below I have put together a list of some great fixes that should help you reconnect to your WiFi.

Software related issues on your iPhone can be caused by many reasons. Usually, this happens after an update of the iOS version of the iPhone. So if your iPhone won’t connect on WiFi just after an iOS update that is most likely the problem.

Hardware issues could happen when the network connectivity between the iPhone and the router is broken. However, there are other issues that cause WiFi connectivity problems on iPhone as we shall discuss. 

A large number of iPhone users should have experienced some Wi-Fi problems causing different challenges in business communication and transaction. If you can’t access the internet, it is impossible to make voice calls, respond to emails, software update and more. This can be super disturbing especially for business owners. 

Is your iPhone having any of these issues?

  • Drops WiFi connection. 
  • WiFi Continuously turning itself on and off.
  • Your WiFi disconnects after the iPhone is locked. 
  • Slow internet (WiFi) connection. 
  • Wrong WiFi password on your iPhone.
  • iPhone won’t connect to WiFi after iOS Software update
  • Greyed out iPhone WiFi emblem

Here are some great things to check when your iPhone won’t connect to WiFi.

ISP, Modem and Router Problems. 

Sometimes the internet service provider (ISP) might be having issues with their network. If so, everyone using their service will experience issues. This will cause your WiFi not to work at your home or office.  

Have you tried troubleshooting the modem or router and your iPhone doesn’t connect to WiFi?

You should start by checking to see if the router or modem is connected to the internet. The first thing to check is the connection of the cables. Did any of them come loose? Is the power on?

If the connections all look normal and the power is on then you can try to connect a laptop by Ethernet cable to your router to see if it is online. If you want to skip this step then keep reading.

Also, make sure your iPhone is within the range of your wireless router. This is important because too great of a distance or any obstacles could be blocking the WiFi connection.

If after troubleshooting the router or modem your iPhone doesn’t get connected to WiFi, you should contact your internet service provider (ISP) to find out if there is any outrage on their side.

If the problem has been caused by the ISP, they will need to fix the problem from their side.  This could be a simple reset of your equipment that they can do remotely. If that doesn’t work, then they might need to send a tech out.

Make sure to talk to their repair department on the phone first because they might be able to walk you through a solution. This could avoid some extra charges.
