Is your iPhone’s Wi-Fi acting up? Don’t fret, I’ve developed some tried-and-tested troubleshooting tips over the years of playing tech support for family and friends. These fixes help me diagnose Wi-Fi issues when I can’t get online.

Toggle iPhone Wi-Fi on and Off

The first thing I do to troubleshoot intermittent internet issues is switch off Wi-Fi in Settings > Wi-Fi and wait at least a minute before turning it back on. The Wi-Fi software stack in iOS isn’t bug-free. Toggling Wi-Fi can resolve the issue. I never disable Wi-Fi via the Control Center, as doing so doesn't truly turn off Wi-Fi radios in my iPhone.

If the Wi-Fi icon in the iOS status bar disappears briefly before reappearing again, this is a tell-tale sign the Wi-Fi software stack just crashed.

Restart Your iPhone

A quick restart can resolve common software issues encountered on an iPhone. To reach the slide-to-power-off screen, go to Settings > General > Shut Down or touch and hold the Power button in the top-right corner of iOS 18’s Control Center.

If the system has become unresponsive, force-restart your iPhone. After a restart, double-check that Wi-Fi is turned on in Settings and your preferred Wi-Fi network is listed there.

Check Network Cables and Connections

Are your cables adequately plugged into your router and modem? Check all the connection points for any signs of failure and see if replacing the Ethernet cable helps.

This might sound basic, but is your router connected to the modem and turned on? If no lights are blinking, the device could be turned off or malfunctioning.

Reboot Your Router

If no nearby networks are listed in Settings > Wi-Fi, the router may need a fresh start. To reboot your router, unplug it and wait at least 30 seconds before plugging it again. If the router gets its internet connection from a separate modem, be sure to also restart the modem too.

Be patient as your router re-enables the 5GHz band. After a restart, my dual-band Apple TimeCapsule takes a few minutes to initialize its 5GHz network.

With everything rebooted, go ahead and make sure the iPhone is within range. Too far from the router, and I get poor or no signal at all. Placement matters, people, so learn how to reposition your router for the best Wi-Fi speeds. I’ll also check for the common things that may be blocking the Wi-Fi signal, such as concrete walls, bookshelves, fish tanks, and the like.

Check Your Internet Connection

Not being able to use Wi-Fi could imply a network issue on the ISP end. To confirm this, I look for a “No Internet Connection” label below the network name in the Wi-Fi settings.

This tells me the network is offline. Your ISP should have a status page that you can check, but you'll need to use a cellular connection to reach it.

Scan any ISP support pages and social media accounts for any outage notices. Once you've confirmed that the problems are on the service provider's end, you might want to wait it out before reaching out to support.

Status dashboards aren't very helpful if they don't update in real-time. That's why I prefer having a support agent acknowledge the issue, to save me from wasting my time on further troubleshooting tips that won’t work.

Enable the Auto-Join Setting

Maybe the ISP did experience a brief downtime, but you're still having Wi-Fi issues? You could be connected to the wrong network. I'll rule that possibility out by looking for a blue tick beside the name of the connected network in Settings.

To configure your iPhone to always connect to your preferred Wi-Fi network, hit the "i" button next to the connected network name in Settings > Wi-Fi and turn on the “Auto-Join” switch.

Check Your Wi-Fi Password

If I see “Unable to join the network” or “Incorrect password” after entering the Wi-Fi password, I’ll restart all my devices, routers, and modems and try entering the password again.

Still unsuccessful? Try changing the Wi-Fi network name and password.

Forget and Re-Add Your Wi-Fi Network

Forgetting a network removes all its saved data, which might fix your issue. Touch the "i" button next to the connected network name and choose “Forget This Network.”

After that, try rejoining the same network to see if the issue has been resolved.

Disable Custom DNS Servers

Still no luck? At this point, I’m eager to point the finger of blame at custom DNS settings. In all honesty, I have changed my iPhone’s DNS servers to a third-party provider to enjoy faster browsing, to be protected from known malicious websites, and to circumvent DNS-level censorship.

To change the DNS server on your iPhone, hit the "i" button next to the network name in Settings > Wi-Fi and select “Configure DNS,” then choose “Automatic” and hit “Save.”

You can always plug in another custom DNS server address once you've resolved the problem.

Turn Off the Private Network Address Feature

Every iPhone sends a unique MAC address to identify itself on the network. These are set at the hardware level but can be manually changed to boost online privacy and reduce tracking. This option is known to cause problems with certain networks, so try turning it off.

Go to Settings > Wi-Fi, hit the "i" button next to the network name, and switch off the option labeled “Private Address” (iOS 17 and older) or “Rotate Wi-Fi Address” (iOS 18).

Turn Off Content Blockers

If you use Safari extensions to block ads, you can disable them on the fly. Hit the “aA” button in Safari’s address bar and choose “Turn Off Content Blockers” from the menu.

To turn off content blockers for all websites, go to Settings > Safari > Extensions (iOS 17 and earlier) or Settings > Apps > Safari > Extensions (iOS 18).

To uninstall these things permanently, you must delete apps they came bundled with.

Disable iCloud Private Relay or a VPN

iCloud Private Relay is Apple's fancy privacy feature which uses CloudFlare’s relay servers to stop websites and ISPs from tracking your IP address, location, and browsing activity. However, it can break some websites and slow browsing speed due to encryption overhead.

To disable iCloud Private Relay, click your profile name at the top of the Settings app, navigate to iCloud > Private Relay, and switch “Private Relay Off” off, then select “Turn Off Until Tomorrow” or “Turn Off Private Relay” to disable the feature entirely.

iCloud Private Relay is only available with paid iCloud+ plans and Apple One bundles. You can also try disabling any VPN connections to have active, by launching your VPN provider's app and disconnecting manually.

Remove VPN and Configuration Profiles

A bad VPN or proxy configuration could also be the culprit. Turn off or delete your VPN and proxy in Settings > General > VPN & Device Management.

While you're at it, remove old configuration profiles you may see here. I found an old configuration profile installed by Apple Support, so I went ahead and deleted it.

Reset the Network Settings on Your iPhone

You can reset all saved Wi-Fi networks and their passwords, along with your mobile data, VPN, and APN settings, in one fell swoop by venturing into Settings > General > Transfer or Reset iPhine > Reset > Reset Network Settings and follow the instructions.

This is something of a last resort, since you'll have to connect to all frequently-accessed networks again.

Try Using Wi-Fi on Another Device

No dice? The next tip in my arsenal is checking whether I can connect to the same Wi-Fi network using another device. If not, my iPhone's Wi-Fi radio might be broken so it might be time to book a repair appointment with the Genius Bar at the Apple Store.

어디서나 모든 것을 업데이트하세요

내 iPhone에는 아무런 문제가 없다는 것이 밝혀졌습니다. 하지만 로그오프하기 전에 내 모든 장치가 최신 상태인지 확인하는 등 몇 가지 팁이 더 있습니다. iPhone의 최신 업데이트를 설치하려면 설정 > 일반 > 소프트웨어 업데이트를 클릭하고 화면의 지시를 따르십시오.

제조업체가 보안 취약점을 패치하고, 버그를 수정하고, 최신 기능과 향상된 기능을 제공하는 새 버전을 출시하면 라우터 펌웨어도 업데이트될 수 있다는 점을 잊지 마십시오.

라우터가 자동 업데이트를 제공하지 않는 경우 라우터에 내장된 웹 인터페이스를 통해 직접 설치하세요. 지침은 제조업체의 지원 페이지를 참조하세요.

해당 제품에 사용되는 Wi-Fi 라우터, 베이스 스테이션 및 액세스 포인트에 대한 권장 설정이 나열된 Apple 지원 페이지를 꼭 읽어보세요.

iPhone을 공장 설정으로 재설정

모든 것이 실패하면 iPhone을 재설정하는 것이 유일한 옵션입니다. iPhone을 재설정하려면 설정 > 일반 > iPhone을 전송하거나 재설정하고 지침을 따르십시오.

iPhone의 비밀번호 또는 Apple ID 비밀번호를 입력하라는 메시지가 표시됩니다. 이 작업을 확인할 기회가 한 번 더 주어집니다. 이 시점 이후로는 돌아갈 수 없습니다.

이는 핵 옵션이므로 iPhone을 Mac에 백업하거나 iCloud 백업을 수행하여(iCloud 저장 공간을 업그레이드해야 할 수도 있음) 나중에 복원할 수 있도록 하십시오.

마지막으로 Apple에 문의하세요

도움이 되지 않으면 Apple에 문의하세요.

이 팁은 iPhone의 Wi-Fi 연결 문제를 해결하는 데 도움이 됩니다.

다른 Wi-Fi 네트워크에 연결할 수 있다면 라우터/모뎀 또는 ISP에 문제가 있는 것입니다. 그런 경우에는 집에 있는 문제를 해결할 수 있는 기술자를 보내달라고 전화하세요.
