Why can my computer access the Internet when it is wirelessly routed, but I can t plug in the cable

Just re-establish a broadband connection. If it doesn't work, there must be something wrong with your network card.

1. Lack of documents.

0. Turn off the cat's power for 1 minute, try it, 1. In fact, the file is just a help file, you can go online without it, 2. There is a lack of files, 99% of the line is a problem, the line link should be good, and ask the service provider. 3. There are few reasons why the cat is bad, whether the network is stolen by others is not impossible, 4. Whether the network card driver is installed well, or the reason why the network card is broken, is very rare.

2. If you have to install this file, find the file in the i386 directory of the installation disk and copy it to the Windows Help directory of the C drive of your computer, and then restart the computer. You can also go to the Windows Help directory on another computer to copy the file to your Windows Help directory and restart it. If the reboot still doesn't work, re-establish the link, password, be accurate.

If you can't do it again, reinstall the driver.

3. In general, the second step will not be used.

You need to set up your computer's networking mode, there are 2 ways to access the Internet through routing, and dial-up networking. Don't use routing.,It's going to be modified to a dial-up connection.,I think you should be able to set it up.,If you don't m me.。。

Change it to a dial-up connection、、、

Is your router set up, it's not as simple as a direct routing of network cables, you need to set up the routing through your mobile phone or computer before it can be used normally.

1.Connect the line.

Connect the carrier's broadband network cable to the WAN port or WAN port of the router.

You can also refer to: Wiring Diagram.

After the line is connected, if the indicator light corresponding to the WAN port does not light up, it means that there is a problem with the line connection, please check that the network cable is firmly connected or try to change the network cable. For the solution, please refer to: The network cable is connected to the indicator but it doesn't light up?

2.Set up your router to surf the Internet.

1) Check the name of the router's factory wireless signal on the bottom sticker of the router.

(2) Open the wireless settings of your phone and connect to the router's factory wireless signal.

(3) After connecting to Wi-Fi, the phone will automatically pop up the router's settings page. If it doesn't pop up automatically, open your browser and enter it in the address bar. Set the login password of the router in the pop-up window (the length of the password is between 6 and 32 bits), which will be used to manage the router (login screen) in the future, please keep it properly.

As shown in the figure below><4) After logging in successfully, the router will automatically detect the Internet access.

<>5) Set the wireless name and wireless password of the router, and after the settings are complete, click "Finish" to save the configuration. Please be sure to remember the wireless name and wireless password of the router, which will be used when connecting the router wirelessly in the future.

Note: It is recommended to set the wireless name to letters or numbers, try not to use Chinese and special characters, to avoid some wireless clients do not support Chinese or special characters, resulting in no search or no connection.

3.Connect your phone and computer to the Internet.

(2) The wired computer is connected to the LAN or WAN port of the router with a network cable, and the confirmation indicator light is on, so you can access the Internet without other operations.

<> figure out where your network cable comes from, from the optical modem or router, from the optical modem you need to set up a wireless router, if the wireless router is normal, you need to set the computer IP address to automatically obtain, whether the mobile phone or other computers are connected to the Internet normally, cooperate with the analysis to determine the network problem Line failure, or equipment problem, or setting problem.

We are glad you asked: it is usually caused by the DNS server of the computer system being contaminated, or it can be caused by the wrong IP address setting or conflicting IP addresses, or the automatically assigned IP address is not on the same network segment as the actual IP address. In this case, the first thing is to check whether the network at home is connected normally, and after the network cable is connected correctly, be sure to set the correct Internet access and password in the router WAN settings.

When the WAN connection is correct and the configuration is correct, you can view the running status of the WAN port in Running Status. 1. Turn on the computer first and click the start button; 2. Then click Settings; 3. After that, click Network & Internet; 4. After that, click Change Adapter Options; 5. Then right-click on WLAN, and then click on Properties; 6, and then double-click Internet Protocol version 4; 7. After that, set the IP address and DNS address to be automatically obtained, and click OK. Hope it helps you and I wish you a great life.

The network cable can be plugged into the computer to access the Internet, and it cannot be plugged into the router, because the router wants to be set up for networking, and the line separated from the optical modem, we first plug it into the router for networking settings, connect the computer with a network cable to enter, enter the page after entering the page, enter the password on the back of the router, set the Internet password of the router, and you can access the Internet again.

It is possible that the router is not set up correctly.

In general, most routers are set up to automatically obtain IP addresses, which is not a problem.

The problem that is easy to be ignored is that the gateway IP of the router is the same as the gateway IP of the higher-level optical modem, for example, 192 168 1 1, which will cause IP conflicts and cause normal networking.

If you encounter such a problem, you need to modify the gateway IP of the router. It can be modified in the LAN port settings of the router, for example, it can be modified to 192 168 2 1 or 192 168 3 1 and so on.

After the modification is completed, you need to restart the router and log in to the router again, you also need to use the new gateway IP to log in.

That's because the router needs to be configured, and after the configuration is successful, it is confirmed that it can be used normally, and then the computer can connect to the network. If you can't configure it, you can check the router's instruction manual.

If your network cable is plugged into the router, and the router is configured, then your router cannot access the Internet, and you need to reconfigure the router.

It should be that one of your network cables is from the switch, and you can directly plug in the computer to access the Internet normally, without logging in, etc., then connecting to the router is definitely not possible.

Set up the issue. The router needs to be set up, and the router has several ways to access the Internet, such as dial-up Internet access, direct connection, static IP, etc. It must be set up to get online. The specific settings can be set according to the manufacturer's manual. Be careful not to insert the socket in the wrong place.

Plug in the network cable directly to access the Internet, which proves that there is no problem with the external network coming in, it should be dial-up Internet access, right? If you can't connect to the network with the router, check whether the router cable is plugged into the wrong port, and whether the router is set up to automatically disconnect the connection. If it's okay, reset the router settings, and then re-enter the router settings to surf the Internet.

Plugging in the network cable on the computer means that the network cable itself has a network, you need to configure the router accordingly to continue to surf the Internet, you just need to enter the configuration interface of the router, and change the IP of the router to a different network segment.

If you can access the Internet when plugged into a computer, it means that the settings are correct. If you can't connect to the Internet when plugged into the router, it means that the settings of the router itself are incorrect, and you need to change it.

The network cable can be plugged into the computer to access the Internet, indicating the use of dial-up Internet access. Generally, broadband and passwords are entered.

If the network cable is connected to the router, then the router also needs to log in, and in the router settings, enter the broadband password.

Desktops can only access the Internet by connecting to the router via a network cable again. Desktops do not come with a wireless network card.

The router needs to be set up, confirm that the router is normal and not damaged, and then enter the router settings to see if you can get in, and link it after setting.

The network cable must be connected to the computer to use the wireless network, and if it is connected to a router, the computer can only use the wifi to connect to the network.

？？？If you plug it directly into your computer, your computer needs to have a broadband connection before you can access the Internet. The specific connection method needs to see the version of the system, which is generally set up in the control panel, network connection, and new broadband connection, mainly to dial the broadband password to access the Internet.

The router needs to be set up, or it may be that there is a problem with the way you get the IP, so you can reset it according to the manual.

You plug in the router, you also need to log in to the router to set a series of problems such as wifi password and dial-up method, only after the setting is successful, you can go to the Internet normally.

It should be that the network is not working, or there is a problem with the router compatibility.

The device is disabled or the driver is not supported.

There is a corresponding dialing setting on the computer, and the route also needs such a setting before it can be used normally.

Before using the router, it needs to be configured before it can be used!

Summary. What is the reason why the router has a normal wireless network but the laptop can't be connected1Confirm whether the wireless network password is correct This is also a common problem, due to some input methods, you may add an extra space or use the wrong full-width characters, capitalization and other problems, and the wireless router on the password.

2.Check whether it is a false signal Some wireless routers have poor signal quality, or have quality problems, when the laptop is far away, although the signal strength is good, but often unable to connect, this is the wireless signal is false. 3.

Confirm that the IP address is set correctly If you manually set a fixed IP address, you may not be able to connect, and the wireless network is usually connected by DHCP automatic assignment and enters the control panel of the computer - network.

The computer is not connected to the wireless network, the router is fine, and the network cable is also plugged in.

But I'm connected to the Internet, but I still can't connect to the Internet.

Sometimes the system shows that it is already connected but not really connected to the Internet, you can disconnect it and reconnect it again to see if it can connect normally, or restart the computer once; 2.It may be that you have turned on the network before**, you can reset the network settings and browser, and then restart the browser; 3.You can also use 360 and other security butler software, open the first aid kit when the network is disconnected, scan and diagnose what causes the inability to access the Internet, and after repairing, restart the system once; 4.

It is also possible that it is due to your broadband reasons, check whether the payment is in arrears and whether there is an abnormal optical signal on the modem.

The network cable can be plugged into the computer, and the route is also set, but it just can't get on the network.

Comprehensive analysis, there are two reasons:

1. Your computer is different from the router, the detection method is to check whether your computer's IP address is within the IP range that the router can provide, or use your computer to ping the router IP, or the most reliable way to find two computers that are connected to this router to see if they can ping each other.

2. Your router has no network signal at all, the reason may be that the router's access method is wrong, if your computer is plugged into the network cable, it is a static IP, or a dynamic IP, or it is not a need for a client or web page login, which needs to be considered, it is recommended that you set the WAN port IP of the router to be consistent with your computer, in addition, if your computer needs PPPOE login when surfing the Internet, you had better choose PPPOE login on the router, set your login name and password, Let's check out both.

Your dormitory network is estimated to have a broadband signal directly, and you don't need to use a router to dial the number. You can try to go into the router settings screen. Turn off DHCP. The method is to remove the checkbox that is enabled in the DHCP. Restart the router and try it.

Is the route connected to the network the right way? For example, dynamic, static, etc., or dial-up networking?

Also, do you need to access the Internet through a **server?

If the access network cable can access the Internet, then you just don't have the wireless function on the router, you try to turn it on, if you dormitory access network cable can not access the Internet, your distance is not too long.
