許多iPhone用戶紛紛升級到了iOS16，這個新版本帶來了許多實用的功能。然而，有些用戶在升級後卻遇到了一個問題：他們的手機無法連接到網絡，而其他設備都能正常上網。這種情況讓使用者感到困惑和苦惱。

如果你的iPhone在更新了iOS16後出現了無法連接WiFi的問題，或者在顯示已聯網（WiFi/5G/4G）的情況下頻繁斷網，即使開啟再關閉飛行模式也沒有效果，那麼你可以嘗試以下解決方法： 1. 重新啟動裝置：試著重新啟動你的iPhone，有時候簡單的重啟就能解決一些網路問題。 2. 忘記並重新連線WiFi：在設定中找到WiFi選項，點選已連線的網路名稱，然後選擇「忘記此網路」。重新連線WiFi，輸入密碼，看看是否能夠正常連線。 3. 更新網路設定：在設定中找到“一般”選項，然後選擇“關於本機”，點擊“網路設定”，這將重置你的網路設定。重新連線WiFi並輸入密碼。 4. 重置全部設定：如果上述方法仍然無效，你可以嘗試重置全部設定。在設定中選擇“通用”，然後選擇“重置”，點擊“重置全部設定”。請注意，這將清除你的所有設置，包括WiFi密碼和其他設置，所以請確保你有備份。 如果以上方法仍然無法解決問題，可能是iOS16的一個bug，你可以嘗試等待蘋果發布更新來修復。同時，你也可以聯絡蘋果客服或到蘋果授權維修點諮詢解決方案。

小編為大家整理了7個修復iPhone無法連接WiFi或頻繁斷網的技巧，並根據可能的原因選擇對應的方法來解決問題。

1、忘記網路

如果你的iPhone無法連線WiFi，你可以嘗試以下步驟解決問題。首先，你可以選擇忽略目前的WiFi網路設置，然後斷開WiFi連線。接下來，重新輸入正確的密碼進行連線設定。最後，再次檢查是否能夠成功連接WiFi。希望以上方法能幫助你解決WiFi連線問題。

2、重置網路

如果您的網路連線出現問題，重置網路設定是一個可行的解決方案。

打開你的iPhone，進入【設定】-【通用】-【傳輸或還原iPhone】，然後點選【還原】。接著選擇【還原網路設定】，最後確認並點選「重置網路設定」即可完成操作。這樣做可以幫助解決一些網路連線問題或恢復網路設定到預設狀態。記得在操作之前備份好重要的資料！

3、強制重啟

如果其他裝置可以正常連接WiFi並使用資料流量，建議嘗試重新啟動或強制重新啟動您的iPhone。這可能有助於解決WiFi連線問題。

iPhone可能會遇到一些小故障，導致無法連接WiFi或頻繁斷網。不過，一般來說，只要重啟iPhone，問題就可以解決，WiFi連線就能恢復正常。

iPhone8及以後的全面螢幕機型，當遇到需要強制重新啟動的情況時，可以按照以下步驟進行操作：首先，快速按下音量高鍵，然後再快速按下音量低鍵，接著持續按住開機鍵，直到iPhone的螢幕完全黑屏，並出現蘋果標誌。此時，可以放開所有按鍵，等待iPhone自動重新啟動。透過這樣的操作，可以解決一些可能出現的問題，並使iPhone重新啟動。

4. Restore factory settings

If your iOS system fails to connect to the Internet and is disconnected frequently due to updates, it is very likely that the system itself is faulty. To solve this problem, you can try factory reset. This process will restore your device to its original factory state and clear all personal data and settings. Make sure to back up your important data in advance, then follow these steps: 1. Open the Settings app and tap General. 2. Scroll to the bottom of the page and click "About This Mac." 3. On the About This Mac page, find and click the "Reset" option. 4. On the reset page, select "All content & settings." 5. The system will ask you to enter the device password or Apple ID password for confirmation. 6. Finally, click "Erase iPhone" or "Erase iPad" to start the factory reset process. Please note that after a factory reset, your device will reboot and require re-setup and configuration. Hope this method can help you solve the networking problem and restore normal use.

Open iPhone settings and click on General options. In the general options, find the option to transfer or restore iPhone and click to enter. Among the options to transfer or restore iPhone, select Erase all content and settings. Follow the prompts to complete the operation of resetting your iPhone, and the reset will be completed. This will clear all data and settings and restore the iPhone to its factory settings.

Restore factory settings refers to the operation of restoring iPhone to the original purchase state. In addition to hardware failures, other problems can generally be solved. However, it should be noted that restoring factory settings will clear all data on the device, so you need to back up relevant data in advance before operating.

You can easily selectively back up & restore iPhone data with the help of Apple's data management tools.

5. iOS system repair

After upgrading/downgrading the iOS system, jailbreaking, etc., the iPhone may experience WiFi failure or network disconnection. It is recommended to repair the iOS system.

You can try using the Apple phone repair tool. The standard repair mode will not clear device data. This tool supports the easy repair of 150 iOS devices such as white apples, black screens, constant restarts, failed updates, and inability to boot.

6. Update the latest version of iOS16

We know that even the official version of iOS16 has been updating the iOS system to fix various bugs. For example, the latest release of iOS 16.0.2 provides multiple bug fixes and important security updates.

Therefore, if it is not a hardware failure, you can try to update the latest version of iOS16 to see if it can solve the problem of being unable to connect to WiFi, disconnection, etc.

7. Downgrading iOS16 to iOS15

If you encounter network problems after upgrading to iOS 16 that seriously affect your daily life and travel, I suggest you downgrade the system to iOS 15 first. This will restore a stable network connection and ensure your normal use.

Supports the iPhone repair tool for downgrading to iOS15.7. This tool can also handle iOS system failures that may occur during the downgrade process.

Currently, many iPhone users using iOS16 have reported some problems, such as being unable to connect to WiFi, frequent disconnections, etc. In response to these problems, I suggest trying the following seven directions to solve them: 1. Check WiFi settings: Make sure the WiFi switch is turned on and the password has been entered correctly. 2. Restart the router and iPhone: Sometimes, there may be communication problems between the router and iPhone. You can try to fix it by restarting the device. 3. Forget and reconnect WiFi: Find the WiFi option in settings, select the connected network and click "Forget this network", then reconnect. 4. Update the iOS system: Sometimes problems may be caused by system bugs. Updating to the latest iOS version can fix some known problems. 5. Clear network settings: Find the "General" option in settings, select "Restore" and click "Reset Network Settings", then reconnect to WiFi. 6. Check the router settings: Make sure the router settings are correct, such as channel, encryption method, etc. 7. Contact Apple customer service: If none of the above methods work, it is recommended to contact Apple customer service for further consultation and solutions. I hope the above directions can help iPhone users who encounter WiFi connection problems.
