1. Make sure that Wi-Fi is on and connected to the correct network; 2. Restart the router and check whether other devices are abnormal; 3. Reconnect after forgetting the network; 4. Update iOS or reset network settings; 5. Check for hardware damage and signal interference. If the iPhone cannot connect to Wi-Fi, first make sure that Wi-Fi is turned on and connected to the correct network, try to switch the 2.4GHz/5GHz frequency band, restart the router and check whether other devices are affected, enter the password to connect after forgetting the network, update the system or reset the network settings, and pay attention to hardware damage or signal interference problems. Following the steps to troubleshoot can usually solve most connection problems.

If your iPhone isn't connecting to Wi-Fi, it can be frustrating, especially if you're in a place where you expect a solid connection. The issue might not always be with your phone — sometimes it's the network, router settings, or even a small overlooked detail like a typo in the password.

Here are some common causes and what you can do about them:

Check Basic Settings First

Before diving into complex fixes, double-check the basics. Make sure Wi-Fi is actually turned on in your iPhone's settings. Swipe down from the top-right corner (or up from the bottom on older models) to open Control Center and confirm the Wi-Fi icon isn't grayed out.

Also, make sure you're connected to the correct network. If there are multiple networks listed (like 2.4GHz and 5GHz versions of the same name), try switching between them.

• Tap Settings > Wi-Fi
• Toggle Wi-Fi off and back on
• Forget the network and reconnect:
  • Tap the "i" next to the network name
  • Choose Forget This Network
  • Reconnect by selecting it again and entering the password

Sometimes just rejoining the network clears things up.

Router or Network Issues

Your iPhone might be fine, but the router could be acting up. Restarting your router often helps — unplug it for about 30 seconds, then plug it back in.

Also, check if other devices are having trouble with the same Wi-Fi. If they are, the problem is probably with the network or internet service, not your iPhone.

Some routers block certain devices based on MAC address filtering. If someone set that up on your network (common in offices or schools), your iPhone might not be allowed through unless added to the list.

Another thing to consider: older routers may not support newer iOS features or encryption types. If you're using an outdated router, it might not play well with newer iPhones.

iPhone Software and Settings

Occasionally, software glitches or misconfigured settings cause Wi-Fi problems. Updating your iPhone to the latest version of iOS can resolve compatibility issues.

Go to Settings > General > Software Update to check.

You can also try resetting your network settings:

• Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings

?? Note: This will erase all saved Wi-Fi passwords and Bluetooth pairings, so only do this if other fixes don't work.

Another less drastic option: go to Airplane Mode. Turn it on for about 10 seconds, then turn it off again. This often resets wireless connections in a quick and safe way.

Hardware and Signal Strength

If none of the above works, the issue might be hardware-related. If your iPhone has been dropped or exposed to moisture recently, internal damage could affect Wi-Fi connectivity.

Try checking signal strength — if you're far from the router or there are thick walls in the way, your signal might be too weak. Move closer to the router or see if the signal bars improve.

Also, avoid interference from other electronics like microwaves, cordless phones, or Bluetooth devices operating on the same frequency.

Basically, most Wi-Fi connection issues with an iPhone come down to simple mistakes, network problems, or minor software hiccups. Try the steps in order, and chances are you'll get back online without needing professional help.
