Android手机的一个非常常见的问题是，即使连接到WiFi，它也无法连接到互联网。这非常令人沮丧，因为它会阻止您上网。互联网(Internet)已经成为我们生活中不可或缺的一部分，当我们没有互联网连接时，我们会感到无能为力。更令人沮丧的是，尽管安装了WiFi路由器，但我们仍无法连接互联网。如前所述，这是一个常见问题，可以轻松解决。在本文中，我们将准确地教您如何解决这个烦人的问题。我们将列出一系列解决方案，以摆脱“ WiFi无法上网”的烦人消息。
修复 Android 连接到 WiFi 但无法上网(Fix Android Connected To WiFi But No Internet Access)
方法一：检查路由器是否连接到互联网(Method 1: Check If the Router is connected to the Internet)
这听起来可能很愚蠢，但有时会出现这个问题，因为实际上没有互联网。原因是您的WiFi路由器未连接到互联网。要检查问题是否确实出在您的WiFi上，只需从其他设备连接到同一网络，然后查看您是否可以访问互联网。如果不是，则意味着问题出在您的路由器上。
要解决此问题，首先检查以太网电缆(ethernet cable)是否正确连接到路由器，然后重新启动路由器。如果问题仍未解决，请打开路由器软件或访问互联网服务提供商的网站检查您是否已登录。确保您的登录凭据正确。如果有任何错误，请纠正它，然后尝试重新连接。此外，请尝试访问不同的网站，以确保问题不是因为您试图访问被阻止的网站。
方法 2：关闭移动数据(Method 2: Turn off Mobile Data)
在某些情况下，移动数据可能会对Wi-Fi 信号(Wi-Fi signal)造成干扰。这可以防止您在连接到WiFi(WiFi)后使用互联网。当存在WiFi或移动数据选项时，Android会自动选择WiFi。但是，某些WiFi网络需要您先登录才能使用。有可能即使您登录Android系统后也无法将其识别为稳定的互联网连接。由于这个原因，它切换到移动数据。为了避免这种复杂情况，只需在连接到WiFi网络时关闭您的移动数据。简单地(Simply)从通知面板向下拖动以访问下拉菜单，然后单击移动数据图标将其关闭。
方法 3：确保日期和时间正确(Method 3: Make sure that Date and Time are Correct)
如果您手机上显示的日期和时间与该位置的时区不匹配，那么您可能会遇到连接互联网的问题。通常，Android手机会通过从您的网络提供商处获取信息来自动设置日期和时间。如果您已禁用此选项，则每次切换时区时都需要手动更新日期和时间。更简单的替代方法是打开自动日期(Automatic Date)和时间(Time)设置。
1. 进入设置( settings)。
2. 单击系统选项卡(System tab)。
3. 现在选择日期和时间选项(Date and Time option)。
4. 之后，只需打开开关即可自动设置日期和时间( automatic date and time setting)。
方法 4：忘记 WiFi 并重新连接(Method 4: Forget WiFi and Connect Again)
解决此问题的另一种方法是简单地忘记 WiFi(Forget WiFi)并重新连接。此步骤将要求您重新输入WiFi的密码，因此请确保在单击忘记 WiFi(Forget WiFi)选项之前您拥有正确的密码。这是一个有效的解决方案，通常可以解决问题。忘记(Forgetting)并重新连接到网络会为您提供一个新的 IP 路由，这实际上可以解决没有互联网连接的问题。去做这个：
1.从顶部的通知面板(Drag)下拉下拉菜单。
2. 现在长按WiFi符号打开WiFi 网络(WiFi networks)列表。
3. 现在只需点击您连接的 Wi-Fi 的名称。( name of the Wi-Fi)
4. 单击“忘记”选项(‘Forget’ option)。
5. 之后，只需再次点击相同的WiFi并输入密码并单击连接。
并检查您是否能够修复 Android 连接到 WiFi 但没有互联网访问问题。(fix Android Connected to WiFi but no Internet access issue.)如果没有，则继续下一个方法。
方法 5：确保路由器没有阻塞流量(Method 5: Make sure that the Router is not blocking Traffic)
您的路由器(router)很有可能会阻止您的设备使用互联网。它会阻止您的手机连接到其网络以访问互联网。为确保您需要访问路由器的管理页面并检查您的设备的MAC id 是否被阻止。由于每个路由器都有不同的访问其设置的方式，因此您最好使用谷歌搜索您的模型并学习如何访问管理页面。您可以在设备背面查看管理页面/门户的IP 地址。(IP address of the admin page)到达那里后，使用您的用户名和密码登录，并检查是否可以找到有关您设备的任何信息。
方法 6：更改您的 DNS(Method 6: Change Your DNS)
您的Internet 服务提供商(Internet Service Provider)的域名服务器可能存在问题。要检查这一点，请尝试通过直接输入其 IP 地址来访问网站。如果您能够做到这一点，那么问题出在您的ISP的(ISP)DNS（域名服务器）上。这个问题有一个简单的解决方案。您需要做的就是切换到Google DNS (8.8.8.8; 8.8.4.4)。
1.从顶部的通知面板(Drag)下拉下拉菜单。
2. 现在长按 Wi-Fi 符号打开Wi-Fi 网络(Wi-Fi networks)列表。
3. 现在点击Wi-Fi 的名称(name of the Wi-Fi)并按住它以查看高级菜单。
4. 单击修改网络(Modify Network)选项。
5. 现在选择IP 设置(IP settings)并将其更改为 static(change it to static)。

WiFi路由器具有不同的无线模式。这些模式对应于工作带宽。这些即 802.11b 或 802.11b/g 或 802.11b/g/n。这些不同的字母代表不同的无线标准。现在默认情况下，无线模式设置为 802.11b/g/n。除了一些旧设备外，这适用于大多数设备。无线模式 802.11b/g/n 与这些设备不兼容，可能是“无法访问 Internet”问题的原因。为了简单地解决问题：
1. 打开您的Wi-Fi 路由器(Wi-Fi router)的软件。
2. 进入无线(Wireless)设置并选择无线(Wireless)模式选项。
3. 现在您将出现一个下拉菜单，单击它，然后从列表中选择 802.11b(select 802.11b)，然后单击保存。
4. 现在重新启动无线(Wireless)路由器，然后尝试重新连接您的Android设备。

Method 1: Check If the Router is connected to the Internet
It might sound stupid but at the times this problem arises because there is actually no internet. The reason being your WiFi router not being connected to the internet. To check that the problem is actually with your WiFi, simply connect to the same network from some other device and see if you can access the internet.

If there is any mistake, rectify it and then attempt to reconnect. Also, try to visit different websites to ensure that the problem is not because you were attempting to access blocked websites.
Method 2: Turn off Mobile Data
On certain occasions, mobile data can cause interference with the Wi-Fi signal. This prevents you from using the internet even after being connected to the WiFi. When the option of WiFi or mobile data is present, Android automatically chooses WiFi. However, some WiFi networks require you to log in before you can use them. It is possible that even after you log in the Android system is unable to recognize it as a stable internet connection. Due to this reason, it switches to mobile data. In order to avoid this complication, simply switch off your mobile data while connecting to a WiFi network.

If the date and time displayed on your phone do not match with that of the time zone of the location, then you might face problem connecting to the internet. Usually, Android phones automatically set date and time by obtaining information from your network provider. If you have disabled this option then you need to manually update the date and time every time you switch time zones. The easier alternative to this is that you switch on Automatic Date and Time settings.
1. Go to settings.
2. Click on the System tab.
3. Now select the Date and Time option.
4. After that, simply toggle the switch on for automatic date and time setting.

This step would require you to re-enter the password for the WiFi, thus make sure that you have the correct password before clicking on the Forget WiFi option. This is an effective solution and often solves the problem. Forgetting and reconnecting to the network gives you a new IP route and this could actually fix the issue of no internet connectivity. To do this:

There is a good chance that your router might be blocking your device from using the internet. It is preventing your phone from connecting to its network in order to access the internet. To make sure you need to visit the admin page of the router and check if your device’s MAC id is being blocked. Since every router has a different way of accessing its settings, it is better that you google your model and learn how to access the admin page. You can check the back of the device for the IP address of the admin page/portal. Once you get there, log in with your username and password and check if you can find any information about your device.
Method 6: Change Your DNS
It is possible that there is some problem with the domain name server of your Internet Service Provider. To check this try accessing websites by directly typing their IP address. If you are able to do that then the problem lies with the DNS (domain name server) of your ISP. There is a simple solution to this problem. All that you need to do is switch to Google DNS (8.8.8.8; 8.8.4.4).

A WiFi router has different wireless modes. These modes correspond to the operating bandwidth. These are namely 802.11b or 802.11b/g or 802.11b/g/n. These different letters stand for different wireless standards. Now by default, the wireless mode is set to 802.11b/g/n. This works fine with most of the devices with the exception of some old devices. The wireless mode 802.11b/g/n is not compatible with these devices and might be the reason for the “No Internet Access” problem. In order to solve the problem simply:
1. Open the software for your Wi-Fi router.
2. Go to the Wireless settings and select the option for Wireless mode.

6. Now try connecting to the WiFi network again and see if you’re able to fix Android Connected to WiFi but no Internet access issue.
Method 10: Perform a Factory Reset on your Phone
This is the last resort that you can try if all of the above methods fail. If nothing else works, you can try to reset your phone to the factory settings and see if it resolves the problem. Opting for a factory reset would delete all your apps, their data and also other data like photos, videos, and music from your phone. Due to this reason, it is advisable that you create a backup before going for a factory reset. Most phones prompt you to backup your data when you try to factory reset your phone. You can use the in-built tool for backing up or do it manually, the choice is yours.
