How to Fix iPhone 12 Wi-Fi Issues

Are you experiencing those Wi-Fi problems with your iPhone 12? For example, your iPhone 12 won’t connect to wifi, connected but no Internet or the network speed is super slow, etc.

Using Wi-Fi is a bit like watching a duck swim: it might look simple on the surface but underneath the water those little feet are going like crazy. Wi-Fi is a great thing, but its complexity means it can also suffer from all kinds of irritating issues. We rely on WiFi to perform various tasks, and when it inevitably experiences an error of some sort, all you want to do is throw your hands in the air.

After all, WiFi frequently seems to be on the more technical end of things, shrouded in mysterious terms like “DNS”, “modem”, and “IP address”. As a result, it can be a bit intimidating to try and fix iPhone 12 Wi-Fi problems without worrying that you’re either doing nothing or making the problem worse.

But no one likes mindlessly refreshing a webpage and hoping the WiFi fixes itself in the meantime, so in this article, we’ll show you a few ways you can take matters into your own hands to resolve iPhone 12 Wi-Fi issues.

Most iPhone 12 Wi-Fi issues are easy to fix, so you can get reconnected relatively quickly. When your Wi-Fi goes down, you can restore access on your own by troubleshooting some of these common iPhone 12 Wi-Fi problems.

problem: iPhone 12 cannot Connect to Wi-Fi network

Your iPhone 12 is failing to connect to Wi-Fi and you cannot figure out the issue. Maybe your friend can connect their iPhone without issue, maybe you can only connect with your computer, or maybe none of your devices are connecting at all. Maybe certain networks allow your iPhone to connect, or maybe you can’t connect to a single network at all.

The fix

Many iPhone 12 mini Wi-Fi problems can be traced to common errors, such as not entering the correct Wi-Fi password. Passwords are case-sensitive, so make sure that the Caps Lock isn’t on and verify that you’ve entered the correct password. If you enter the wrong Wi-Fi password, you’ll get a message that asks you to try again.

For wireless router issues, you might need to reset your router and modem to restore your Wi-Fi network connection. The modem needs to be restarted because they work together.
To restart your router and modem, unplug the router and modem power cords from their power sources. Wait at least 30 seconds, and then plug both the router and modem back into their power sources. The router and modem should fully power up within a few minutes. When you see blinking green lights on the devices, you’ll know they are fully powered.

Problem: iPhone12 Wi-Fi connection is slow

iPhone 12 is experiencing extremely slow WiFi speed. You may have a powerful router, and its signal may reach everywhere in your house, but your internet speeds may be much slower than they are supposed to be.

The fix:

First things first: is it a busy public access point that you’re sharing with lots of people? If so, the only way to get a big speed boost there is to use it at a quieter time, which isn’t exactly practical if you’re on a bus, train or in work, we know.

Getting physically closer to the router can make a huge difference – Wi-Fi, especially the older standards, is hugely range-dependent – and if you can physically see the router that’s even better. Wi-Fi suffers badly from interference, especially from metal objects, and if walls between you and the router have chicken wire-style mesh underneath the plaster or big metal radiators hanging on them, then that can make your iPhone 12 Wi-Fi slow.

It’s also a good idea to ensure that nothing else is connecting to the network at the same time as you. In a typical home there are all kinds of things trying to access the Wi-Fi network from smartwatches to smart TVs and even smart energy meters, and the more devices online at once the less bandwidth there is to go round.

If that’s not the issue, it could be that your current wireless channel is overcrowded by those of other nearby networks. Consider changing the channel on your router in your router settings. Each router brand does that a little differently, though.

If that doesn’t help, performing a factory reset on your router and setting it up again may help. On most routers, there’s a Reset button that you can hold down with a paperclip. Do so for 30 seconds, and the router should default from factory settings.

Problem: iPhone 12 keeps disconnecting from Wi-Fi

Sometimes when your iPhone 12 connects to your home network, the connection later drops out.

The fix:

If you’re constantly getting dropped Wi-Fi connections on iPhone it’s a good idea to get closer to the router or to change your router’s settings to try another radio channel that might be less congested.

Your problem could also be with the router itself: we’ve found that certain low-rent modems go up and down more frequently than a kangaroo in a lift. If you’re having problems with more than one device, go and give the router a kick. Er, we mean reboot it.

Routers aren’t the only cause of dropped connections, though. Rebooting your device is a simple first step – Wi-Fi radios can and do go in a huff from time to time – and it’s worth having a look.

problem: iPhone 12 connects to Wi-Fi but no internet access

It is a common problem: Your iPhone12 does not connect to the Internet. Because there’s no working Internet connection. You check the status of your wireless network connection, and it shows that your iPhone is currently connected to Wi-Fi. However, you cannot get online?

The fix:

It might sound like a tired tip, but try resetting your modem by unplugging it and plugging it back in. If that doesn’t work, try also resetting your router the same way, assuming it’s a separate device.

You can rule this out by connecting a laptop or desktop to your router with an Ethernet cable. If this works, then the router is having a problem and may need to be reset. If there’s still no internet, though, you may have an outage. Contact your ISP.

Problem: iPhone12 Hotspot is not Working or Keeps Disconnecting

Sometimes you are unable to use your iPhone 12 as a personal Wi-Fi hotspot because the iPhone keeps disconnecting unexpectedly and sometimes reconnecting itself.

The fix:

If other devices won’t connect to your hotspot, it may be because the devices are out of range. Ensure that the other devices and your iPhone 12 are close to each other (within 15 feet).
Check to see if the problem is with the hotspot, your iPhone that provides Personal Hotspot, or the other device(s) that connected to it:
Try connecting a different computer or mobile device to the hotspot. If this device can connect, then the problem is not with the hotspot.
Try connecting it to other Wi-Fi connections, if it cannot connect, then the problem is not the hotspot.
Try visiting another website (e.g., or if they can load, then the problem is not the hotspot.
Please make sure that your iPhone 12 is running the latest version of the iOS software. You can update (or check for updates) by going to Settings > General > Software Update.
Please ensure that the other device has the latest version of its software/firmware installed. Contact its manufacturer for further help.
Make sure that Personal Hotspot is enabled on your iPhone (Settings > Personal Hotspot). Furthermore, ensure that Allow Others to Join is turned on. And lastly, ensure that Maximize Compatibility is enabled (Settings > Personal Hotspot).
Restart your iPhone and the other device(s) that are connected to your Personal Hotspot.
Turn off Wi-Fi and wait 30 seconds and turn on Wi-Fi on the other device that is trying to connect to your iPhone.
