What should I do if my iPhone shows that it is connected to wifi but cannot access the Internet?

There are two scenarios: one is that the network share of the local connection and the wireless network connection is not set up; The second type is the reason why the IP address of the iPhone 4 is not updated after connecting to the temporary wireless network. Let's take a look at how to fix iPhone can connect to wifi but can't connect to the internet.

Creation of a temporary wifi network.

1. First of all, establish a temporary network connection of wifi in win7.

2. Use your iPhone4 to connect to this network.

3. At this time, the temporary network of win7 should be displayed as connected, enter the "Change adapter settings" option in the "Network and Sharing Center", double-click the "Wi-Fi connection" (if the name is different, select the icon with a green signal bar on the icon, and the words Intel(R) WiFi Link ** will usually be displayed below), please make sure the connection status of the network.

4. Select "Details", the IPv4 address should be displayed, if not, please reset the network, or restart the phone and reset the network.

4. In the iPhone4 "Settings", select WiFi and click the blue arrow after the selected network name, and the IP address in DHCP may be displayed as.

5. Select Static and manually enter the following IP address: Any number between No. 2-254) Subnet Mask: Router: DNS: 5. Wait about 15-30 seconds.

Detection method of wifi temporary network.

Method 1: Landin weather, if it can be updated, it means that the connection is successful.

Method 2: Enter the "Change Adapter Settings" option in Win7 "Network and Sharing Center", double-click the icon of "Wi-Fi Connection", and see the "Received" value change under the "Activity" area, indicating that the connection is successful.

Special case handling: If the iPhone4 locks the screen and then turns it on, it shows that the wireless network is connected on the iPhone4, but the "Wi-Fi connection" icon in W7 shows "Not Connected" below, please turn off the wifi switch on the iPhone4 and turn it back on again, which can solve this problem. The above methods can solve some specific problems, if there are other problems that will be discussed and solved.

iTone can connect to WiFi but can't connect to the Internet or may not be able to connect to the temporary network, so make sure that the ipone can connect to the wifi temporary network first.

Reset your network settings.

Look at the network to see if there is a problem.

That's a network problem, and it has nothing to do with the machine.

It could be a phone issue, or it could be a network issue:

Check your router settings.

Step 1: Open the browser of the computer connected to the current wireless router, enter part of the router in the address bar, check the bottom label of the router to know), log in to the web configuration interface of the current router, and the username and password are admin by default

Step 2: Under the network settings of the router, first find the WAN port setting option of the router. Setting the "type" correctly here is the crux of the matter.

There are two commonly used types: PPPoE and DHCP. Choose this according to your own situation.

If it is a home ADSL dial-up Internet access, choose PPPoE; If there is a direct network interface available, such as cell broadband or a hotel, DHCP is chosen

Step 3: If it is DHCP, there is no need to make other settings, and the router will automatically obtain the corresponding network settings. If you choose PPPoE, you need to fill in the correct username and password, which are provided by network service providers, such as China Telecom, and if you forget your password, you can call 10000 for manual consultation.

Step 4: Next, check the LAN port settings of the router. The settings of different brands are actually similar, the most important thing is to turn on the DHCP function, so as to ensure that the router can assign an IP address to the device when it is connected to the LAN port or connected to WiFi, and the IP address range assigned by DHCP should be in the same network segment as the IP address of the router, for example.

Step 5: Finally, check the security settings of your router. Check whether you have enabled some security policies that restrict MAC or IP address connections, or the corresponding rate limiting policy, and if so, turn them off, otherwise only devices with specific MAC or IP addresses can connect.

Check your phone's settings.

Step 1: Open your phone's settings, select "Wi-Fi", and then, when you see the wifi signal that you are currently connected to, click on the small blue circle arrow on the far right.

Step 2: Click "Ignore this network". Then, the wifi connection of the mobile phone will be disconnected, so that the mobile phone will not automatically connect when you click to connect to the signal source again, but will re-enter the connected wifi password, that is, the mobile phone will re-identify the network once, so that you can achieve the effect of emptying the original network configuration.

Step 3: If you want to clear it more thoroughly, you can open Settings ---General --- Restore and select "Reset Network Settings". In this way, the device will restart, and after the restart, all previously connected networks will not be saved, but will be recognized as a new network, and the wifi password will be entered to connect.

Workaround:

1. Use other mobile phones or devices to connect to wifi to try whether you can access the Internet, and rule out the wifi itself.

2. Restart the router to try, or restore the router to factory settings, then dial up the Internet again, and reset the wifi according to the setup wizard, or change to a new router and dial up to connect to the Internet.

3. Contact broadband customer service to confirm whether there is any abnormality in the broadband account, such as arrears, recharge the broadband, and then dial up to connect.

4. If the wifi name contains Chinese, it is recommended to modify it to English or a combination of English and numbers before connecting.

5. If the above reasons are ruled out, it is likely to be a problem with the mobile phone system for a long time, it is recommended to restore the factory settings or flash the phone to see if it can solve the problem.

Hello, wifi signal regardless of whether there is a network mobile phone and other equipment can be connected, the user can not use the network after connecting to wifi, first confirm whether your broadband line is smooth, you can check whether the indicator light of the broadband cat has LOS red light flashing, if there is a broadband failure, so the router's wifi can not use the network, at this time, the user can call the operator's customer service to report the fault processing, after the fault report, there will be staff to come to the door to troubleshoot.

If the broadband modem can be connected to the network normally, then it is a problem with the router, and you can check whether the network cable is connected correctly. If the network cable between the broadband modem and the router is normal, you can restore the router to its factory value, and then reset the router parameters to see if it can be restored to normal

2. Then open the browser and enter the management address and login password of the router.

3. After logging in to the background, click the setup wizard, and then fill in the corresponding parameters according to the wizard instructions.

6. After the wireless setup is completed, click Save, and then restart the router to use it normally.
