An exclamation point appears when the computer is connected to the wireless router

Are you adding a wireless router (= with 2 routes)? Or replace the original route with a wireless route, after coming out of the cat to the route can only pass once, if you first come out of the original route and then connect to the wireless route, then there will be the yellow exclamation point you said.

Default gateway: This can be filled in without filling, the computer will fill it in by itself), IP address: The specific situation should be set according to your router manufacturer, if the above is not used, just use it, IP address:

You try it, and hopefully it will work.

It's a static IP, so set the IP into the router, and then change the IP of the local connection to automatic.

Restricted connection,Routing and the Internet are not connected,If it is win7 system has its own diagnosis, you can try it。

Win7 system is because it has not been connected, if it is XP, it is because your network has not been connected.

It wasn't connected at that time, but it will be fine after a while, or restart the router, I hope it can help you

1. XP system: double-click the local connection icon in the lower right corner of the computer screen, select "Properties" after the pop-up window, pull down the scroll bar on the right with the mouse after the pop-up window until it appears, and then click the "Properties" below, and select "Automatically obtain IP address" and "Automatically obtain DNS server address" after the pop-up window.

If you don't have an IP address, you can try to enter it manually.

Reasons why wireless routers keep having exclamation points and how to solve them.

1. The reason is that the router is not turned off normally or the router battery is aging. The solution is to press the reset button on the router for 5 seconds, and then go to the corresponding router to reset the password and other information.

2. The reason is that the router line port is faulty, sometimes the router emits too much static electricity will also lead to this error, and sometimes the network cable socket is not strong. The solution is to press the reset button on the router for 5 seconds, and then go to the corresponding router to reset the password and other information.

3. The reason is that this situation will occur when the number of users of your line exceeds its own limit load. The solution is to use ** speed limiting software, such as "P2P Terminator", to force them to take the initiative offline.

4. The reason is the network operator's line problem. The solution is to contact the network operator's customer service or find a broadband repair center. 、

5. This problem will also occur when your firewall is set to restrict Internet access. The workaround is to set the firewall to allow internet access.

If a yellow triangle exclamation mark appears on the network connection, it means that the network is not connected successfully, and you need to manually select the troubleshooting, and the problem will be automatically repaired.

Data is transmitted from one subnet to another, which can be processed through the router's routing function. In network communication, the router determines the network address and selects the IP path.

After the computer is connected to the router, the icon in the lower right corner shows a yellow exclamation mark, and when you click the icon, it will display "Unrecognized Network" or "No Internet Access", as shown in the following figure

Resolution. 1.Check that the computer network parameter settings (or acquisition) are correct.

The IP address configured on the computer (or obtained automatically) is incorrect. If other terminals in the environment can automatically obtain IP addresses, please try setting your computer to automatically obtain IP addresses (How can I set my computer to automatically obtain IP addresses?). ）。

Note: If the DHCP server of the router is in the "Not Enabled" state (that is, all terminals need to manually configure IP before they can access the Internet), make sure that the parameters such as IP address, subnet mask, gateway, and DNS configured for the computer are correct.

2.Check the line connection.

If the IP address cannot be obtained after the computer is disabled and re-enabled, and the Internet cannot be accessed and the management interface cannot be logged in under the manual configuration of parameters, it is recommended to replace the network cable between the computer and the router to eliminate the problem of physical link failure or poor communication quality due to aging network cables, poor network cable quality, or too long network cables (how to judge (select) network cables?). ）。

3.Check your router settings.

Note: The display of Windows XP system computer is restricted has nothing to do with whether the router is connected to the network successfully or the router's Internet access permission settings, so there is no need to check this step.

1] Make sure that the router is connected to the network successfully.

Note: If only a few terminals cannot access the Internet, you can skip this step.

If all the terminals connected to the router cannot connect to the network, check whether the router is connected to the network successfully (the router can be connected to the WAN port to broadband, WDS bridging, network cable LAN cascade, etc.).

1. What should I do if I can't connect to the network after setting up the router?

2. What should I do if I can't connect to the Internet after setting WDS?

3. What should I do if the router is used as a switch (AP) and cannot be connected to the network after setting?

2] Check your router's Internet access controls.

Functions such as forbidden hosts (or Internet access control) are set on the router to restrict the Internet access permissions of terminals, resulting in individual terminals being unable to access the Internet after they are connected. Here's how to fix it:

Log in to the router interface, click "Device Management" Banned Devices, and confirm that no devices are disabled here. If there is a disabled device, click "Unban".

Note: The router with the traditional interface does not have the function of the banned host, you need to check whether the router is set up with parental control Internet access control function, if so, turn off the function and then test the Internet.

4.Replace the computer for testing.

If the above troubleshooting operation is done, the problem is still not solved, it is recommended to change the computer for comparison test, if other computers connect to the router after the Internet is normal, you need to check the system problem of the computer that cannot access the Internet; If other computers are connected to the router through network cables and cannot access the Internet, you need to check whether the router port is faulty and whether the connected network cable is not standard or has quality problems.

From the web.

Reasons for this problem:

1. The IP and DNS settings of the computer are incorrect.

4 There is a problem with the wireless router setup.

Solution:1 Turn off the wireless router and turn it back on after 5 minutes2 Left-click the network in the lower right corner of the computer, find the wireless router right-click status, properties, Internet protocol version 4 Double-click, select Automatically get IP address, automatically get DNS server address. Confirm the exit.

3 Press and hold the reset button on the back of the wireless router, then the computer will find the wireless router signal, double-click it, enter the PIN and set the password as you did the first time you set it.

4 Enter the browser and enter the wireless router settings in **.

If you are unable to access the Internet due to a yellow exclamation mark on the broadband network connection icon of your computer, it is recommended that you open the [Network Sharing Center], select [Change Adapter Settings], right-click the local connection properties, double-click IPv4, select Automatically Get IP, then open [Run], enter cmd, and enter [ipconfig ew] in the command prompt to try to get the IP address again.

The local connection is restricted, which means that you are now connected to the route normally (the so-called LAN), but you have not successfully connected to the Internet and cannot access the Internet. Check whether your router is connected properly, access the router, and check the running status.

No internet access.

In general, it is because you have connected to the router, but the router is not connected to the Internet because it is not set up or set up incorrectly.

Although the computer is successfully connected to the router, it cannot connect to the Internet. Please check your router's external network connection.

One, on the computer:

1. An exclamation mark is displayed on the wireless network sign, which means that the computer is connected to the wifi network but cannot connect to the Internet.

2. It is the permission to appear for network access.

3. Whether your broadband is in arrears, if it is in arrears, this will happen.

4. Sometimes it's because of IP address conflicts, just manually fill in your IP address Start - Control Panel - Network and Sharing Center, click on the wireless network link, click on the property to find the selected part as shown in the figure, double-click and pop up a box to modify the IP address.

Two, on the phone:

1. There are too many router users, resulting in insufficient router resources, and 2. The router has restrictions on you.

Third, restricted, for example, connected but not connected to the network is a type of restriction. It is normal for this sign to appear and then disappear when connecting to a wireless network, which is in the process of identifying the network.

Workaround:

1. First of all, you should make sure that your computer can't be connected because of your own computer, not because of wifi. You can first use your mobile phone to try if it is the reason for wifi. 2. When your computer is in the following situation, and it is determined that it is a problem with the computer.

3. Left-click the icon with the yellow exclamation mark, see open the Network and Sharing Center, and click in.

4. Click to change adapter settings.

5. When you see the wireless network connection, select the icon first, then right-click the icon and click Properties.

6. Double-click Internet Protocol version 4.

7. Change the relevant parameters to the same as the figure below.
