請問有人NEXUS 6P升級到7.0後,WIFI出現連線問題嗎?
前陣子升級到7.0後,在有收到基地台訊號的情況下WIFI都沒有辦法正常連線!
開啟飛航模式後再將WIFI打開,WIFI卻可以連線正常。
之前以為是手機問題,沒想到送修回來之後再度更新為7.0後,這個問題又再度出現!!
到底是7.0的問題還是手機問題啊??

P.S 最近發現,WIFI可以連上5G的訊號,但是2.4G的怎樣就是連不上!!
會不會有可能是路由器的問題?
韌體或是擺放位置或是太久沒重新開?

Hi Robert,

Thank you for contacting Google!

If you are having trouble connecting to Wi-Fi with your device, please follow the steps below.

Step 1: Update to the latest version of Android OS.

Go to 'Settings' > scroll down to 'System' > touch About phone (or tablet) > touch System updates.
If your device is rooted or modified, revert your device to original factory image since troubleshooting steps may not work on modified/rooted devices. You can re-image your device with the instructions from the following link: https://developers.google.com/android/nexus/images
Step 2: Enable safe mode on your device:
In safe mode, Wi-Fi will still function normally and all third-party applications will be disabled. This can help pinpoint issues caused by third-party apps. To restart your device in safe mode:

Ensure your device's screen is on, then press & hold the Power button.
Touch & hold the Power off option in the dialog box.
Touch OK in the following dialog to start safe mode.
To exit safe mode, turn your device off and on again.
If you discover that the issue doesn't occur while your device is in safe mode, it's likely that a third-party app or Android OS modification is causing the issue. You can start to use and narrow down your installed apps to try to pinpoint the specific app. When the culprit is identified, you can uninstall the app or contact the developer of the app for further support as follows:

Navigate to play.google.com.
Find the app and click on it to view its main page.
Scroll down to the "Additional Information" section. Here, you'll see "Contact Developer" options.
Step 3: Visit our Connect to Wi-Fi networks article for basic Wi-Fi instructions:

Follow the steps under the header "Turn on Wi-Fi & connect to a network."
If you're still having issues, also try the tips under the header "Trouble connecting to Wi-Fi."
Step 4: Try to connect using the Wi-Fi 2.4 GHz frequency band.

Nexus 4, Nexus 5, Nexus 7 (2013), and Nexus 10 are compatible with 5 GHz Wi-Fi frequencies, but may have connectivity issues if DFS (Dynamic Frequency Selection) is used.
If you are trying to connect to a 5 GHz frequency, we suggest connecting using a 2.4 GHz frequency or turning off DFS in the router settings.
Step 5: If you have access to the router settings, follow these router troubleshooting steps:

Follow the manufacturer's instructions for updating the Wi-Fi router's firmware (the software that the Wi-Fi station uses to run itself) to the most up-to-date version.
In case of a secured network, it is recommended to disable the password for test purposes.
Make sure your router does not require any specific steps to establish a connection to your network.
Disable MAC address filtering if this is enabled on your router.
Contact the router manufacturer about compatibility with Android devices.
Make sure your router is not using a hidden SSID and your device is able to recognize the network.
Step 6: Reach out to your internet provider, manufacturer of your router, or the responsible network administrator.
Let them know you are having issues connecting your device to your Wi-Fi network. They should be able to investigate or provide possible remedies. Here are other ways to narrow down the issue:

Can you connect to other public/private Wi-Fi networks, such as a hotel, cafe, or a friend's house?
Can other devices connect to the Wi-Fi network that you're having issues with?
Step 7: Reset your device to factory settings.
If your device freezes while in safe mode, you can't narrow down the reason for the freezing, or the issue is so severe that you can't boot your device into safe mode, resetting your device to factory settings may resolve the issue. Resetting your device to factory settings will erase all local data on your device. Backup of your personal local data (pictures, music and video files) is recommended.
