Update to the latest iOS version

Settings → General → Software Update

Upgrading to the latest system software is always a good way to solve any kind of problems on your iPhone. A look back shows that some versions of Apples mobile operating system suffered from WiFi issues that could be fixed by later updates. If you use a buggy version of iOS, you should definitely update it as soon as possible.

To do this, open “Settings” and tap on “General”. After that click on “Software Updates” to check for any available updates. If there’s an update available, you can install it directly without connecting your iPhone to your computer. Otherwise, you’ll simply be informed that your software is already up to date. By the way, you can also install the update automatically overnight.

Disable “Wi-Fi Networking”

Settings → Privacy → Location Services → System Services → Wi-Fi Networking

If the aforementioned tips don’t fix your problems, you might want to give this one a try. Deactivating a specific part of Apple’s so-called “Location Services” will improve the reliability of WiFi connections for some users. This specific option actually does nothing to affect your capability to use your location within apps and services, but helps Apple in building a database of open access router locations across the globe to provide better location services to users without cell access. Switching it off is therefore of no actual disadvantage to you personally and worth a try.

First open the “Settings” app. Tap the “Privacy” section in the menu and select “Location Services”. Now scroll down all the way to “System Services” and deactivate the toggle labeled “Wi-Fi Networking” at the end of the list. This might improve your WiFi connection reliability, as some users report.

Forget and reselect network

If you are unable to connect to a wireless network and you are told that you have entered an incorrect password – despite entering a correct password – you have the option of forgetting the network and then reselect it.

To do this, first go to the “Settings” app and select “Wi-Fi”. Then tap the respective network in the list and choose “Forget This Network”. A small pop-up will appear asking if you really want to forget the network. Then tap on “Forget”.

This solution requires you to know all of your WiFi passwords, so make sure to keep them at hand before you go ahead and try it.

Users have reported improvements in battery life and connection reliability after trying this trick.

Go ahead and open up your “Settings” app. Tap “General” to access the general overview of settings. Scroll down and select “Reset”, finally tap “Reset Network Settings”.

Remember: You will require your WiFi password after applying this fix.

Change DNS provider

Settings → Wi-Fi → [your network name] (i) → Configure DNS → Manual → Add Server

Trying a different provider for your DNS (Domain Name System) can yield quicker loading times for web activities such as browsing or watching YouTube. By default, your iPhone will use the DNS Servers provided by your internet service provider. However, users are free to customize this setting and specify their own choice of DNS servers to circumvent issues or improve performance.

Open your “Settings” app and select “Wi-Fi” to get to the list of your wireless networks. Tap the blue “i”-in-a-circle symbol next to the name of your currently active connection. Then select “Configure DNS” at the very bottom of the screen and choose “Manual”. After that tap on “Add Server” further down. Let’s try the free and publicly available Google service.

Enter “,” to set your primary and secondary DNS server to Google DNS.

An alternative to Google’s offerings would be OpenDNS, use “,” instead, should you prefer OpenDNS. Usually Google is the fastest and most reliable DNS provider for all sorts of locations across the globe.

To revert back to the automatic, default setting, simply clear the field of any user input and your iPhone will pick up whatever settings your ISP recommends.

Switch off Wi-Fi and Mobile Data

In rare cases, it may be necessary to temporarily deactivate both WiFi and mobile data. This is the best way to do this: Open the Control Center by swiping the screen from bottom to top (up to iPhone 8) or by swiping the screen from top right to bottom (iPhone X or newer). Then deactivate Wi-Fi as well as mobile data by tapping on the corresponding icons at the top left. After that switch Wi-Fi on again, followed by mobile data.

You will then be assigned a new IP address and your WiFi will hopefully work fine again.

To do this, go to the “Settings” app, tap on “Mobile Data” and scroll down to the very bottom. Then tap the button to the right of “Wi-Fi Assist” to deactivate and reactivate the feature.
