WiFi issues

For over a week my iPhone 11 isn’t connecting to the WiFi. There’s nothing wrong with the WiFi, as all other devices are using it. I want to update to iOS 15.7 as this could help fix the issue, but am not able. Any ideas?

Hello KCarioca,


The first thing we would suggest would be to power cycle the iPhone by pressing and holding either volume button and the side button until the power-off slider appears. Drag the slider and wait 30 seconds for the device to turn off. While simple, this can refresh the iOS, apps and connections. More information is available here:  Restart your iPhone - Apple Support


If you are still not able to connect to Wi-Fi, follow these steps:


  1. Make sure that your router is on and you're within range
  2. Make sure that Wi-Fi is on and you can see your network
  3. If asked, enter your Wi-Fi password
  4. Check for issues with your Wi-Fi network
  5. Check your cables and connections
  6. Restart
  7. Reset your Network Settings


Detailed instructions for each of those steps is available at If your iPhone, iPad, or iPod touch won't connect to a Wi-Fi network - Apple Support


There is additional information here that may also help: Recommended settings for Wi-Fi routers and access points - Apple Support


Have a good day.

Thank you so much, srbwanderer. I had to unplug and restart the router several times, but it worked in the end. I just don’t understand why the tv and laptop had no WiFi issues.

Wi-Fi normally connects to a router, which assigns an IP address using a protocol called DHCP (Dynamic Host Configuration Protocol). But it’s possible to also use Wi-Fi to connect a group of devices to each other rather than to the Internet in what is called an ad-hoc network. Ad-hoc networks use IP addresses in the range that starts with 169.254.0.0. Each device in the ad-hoc network creates its own IP address in this range. When you connect a device to a network it will "ask" the router for an IP address using DHCP. If it doesn’t get an IP address assigned within 30 seconds it assumes that it is an ad-hoc network and assigns itself a random address in the range 169.254.x.y.


There is a common failure mode in many routers where the DHCP “daemon” process in the router fails, and it stops assigning IP addresses, so a new device connecting to the network will self-assign. But any device connected to the router that already has an IP address will continue to work. This makes it look like the problem is the phone, because everything else connected still works, but it’s actually the fact that the router is no longer assigning IP addresses. While it can happen to any device using the router the problem is more common with phones that disconnect when they go out of range, and reconnect when you get “home” and thus get a new IP address assigned. Rebooting the router restarts the DHCP daemon and resolves the problem.


The reason it happens with many different routers is that most routers have the same underlying open source operating system. It’s primarily a problem with routers more that a few years old; newer ones from top tier manufacturers rarely have this problem.
