Dude, I m in the second case, but what s the reason why I can t even go online

Internet access, line problems, equipment problems, problems, and application problems.

The first category is caused by physical causes. For example, if the client's network cable is not properly connected or damaged, the switch-to-client network is disconnected, the campus network or telecommunications party access fails, etc., except for the first case, several other situations need to be repaired. You can install Tencent Computer Manager, click on the toolbox - computer clinic - directly search for the Internet, there will be a one-click repair method, very convenient.

The second type is caused by system or software reasons. This kind of situation can usually be solved by reinstalling the system or configuring the system correctly.

If your computer can't access the Internet, you should first check whether the physical wiring connected to your computer is normal. The way to detect this is to see if the indicator light of the computer cable jack is on, or to see if Windows

's network connection icon shows "x". As it appears.

If the connection is incorrect, please check whether the network cable is connected, or whether the network is normal, and try another network cable. There is no problem with the network cable, see if there is a problem with the port on the wall, and if possible, you can use another computer and network cable to connect to the port to try.

If there is no problem with the physical wiring, you need to find out if there is a problem with your computer system, and if all the problems are eliminated, then it is time to ask if the school network is down at this time.

Where is the wireless network switch of the computer, and these two faults cannot be connected to the network, so it is solved.

Local connection prompt is restricted or no connection is a problem with the network card, you can try to change the network card mode: above the network neighbor, right-click - properties - after the local connection appears--- right-click - properties --- configuration - advanced - see whether the following properties and values are Chinese or English, if it is Chinese to find "speed and duplex", if it is English to find "speed" - there are several options in the value, choose OK according to your needs. This is only the network card mode, and it is possible that you can use 10bps to access the Internet, but changing to 100bps will be limited.

Which one can be used for Internet access?。。

If you've tried all the modes and you're still throttled or have no connection, you can redo the system and it will usually be back to normal.

Under what circumstances can I not connect to the Internet? Sometimes the router is on, and the network cable is not plugged in, which gives you the illusion that you are connected to the wifi but not on my line. Makes you feel like you're connected to the internet.

There is also a possibility that the bus line is not plugged in, our home is on the Internet, the line is broken, and we still have no way to use the network.

There is also the Internet company that has choked your net. It's useless for us to have a router connected to the end.

Typing is not easy, hope.

Hello, there are many reasons why the network connection is not available, it could be:

1. The network cable is dropped, 2. There is a problem with the network card, 3. The line is not working, 4. The plug is loose, and the above problems can lead to the network connection. So if you don't have a network connection, you can do this:

1. You can restart the computer first, if you restart it or can't connect to the network, you have to see if the indicator light of the router is on, if it is not lit, it means that there is a problem with the network cable, if the indicator light is on, it means that there is no problem with the network cable.

2. Check if there is a fault inside the computer and check the network card.

3. If it still doesn't work, call ** to inquire whether the network fee is due, whether the network card is loose.

4. If it still doesn't work, it should be sent to a professional shop for maintenance.

Extended Materials. Data failures.

Troubleshooting method: Replace the troubleshooting in turn.

One. Hardware issues.

1.Lines are a problem.

Please use a line tester to test whether the network cable is unblocked;

2.Network card. If the network card connector is not in good contact or the network card itself is faulty, please connect a normal network cable and test it with a side line meter to confirm whether the network card is working normally.

3.There is a problem with the switch (router, modem).

You can try to connect the network cable to the end of the switch to a different socket or restart the switch;

4.NIC working mode.

You can try to manually modify the working mode of the network card, change "automatic" to other modes, although you can't understand the reason, sometimes the problem can be solved because of this.

Two. Software issues.

Firewalls are to blame.

The author has only seen this situation once, that is, turn off the firewall that comes with the Windows system and it can be restored to normal.

Because you are not specific, the answer to this argument is:

Theoretically, as long as there is a signal, it can be connected.

While some can connect and some can't, there are 2 reasons for this:

1: MAC binding. This means that the MAC of the device that cannot access the Internet has not passed the verification of the router (can be set).

3: Apple and Android phone wifi connection. (This problem will occur in a few cases, mainly due to the company's network planning problems, such as routers coming out of Layer 2 switches, Layer 2 switches being separated from a thick wireless AP, and wireless APs being separated may cause this problem).

Android can connect while Apple can't connect to wifi.

The theory of this problem seems to be that Android can discover the terminal gateway address through the wireless AP. Whereas, Apple can only identify the gateway that reads the wireless AP assignment. Causing Apple to be unable to access the internet.

You pull all the wires, reconnect them, try it, I'll be fine, maybe it's a bad contact.

The solution to the computer is not connected to the Internet.

Click on the first one

You this,I guess the network cable is not plugged in.,The big one in the lower right corner is very conspicuous.。

Hello, I am the after-sales technician of BAI Brain of Global Electric. du

According to the **, the network cable connection is abnormal, and there are two lines in the dao**. Former.

First, the network cable is not plugged in.

Second, the network card driver is not installed.

3. The network card is broken, and you need to buy a network card.

It's because the router isn't set up correctly, so check the settings of the router!

1. If the WLAN is connected to the modem, there is no DHCP service on the modem, and it is naturally impossible to assign valid IP and DNS to the WLAN, you can set the IP address and DNS of the local connection by yourself (this has nothing to do with Internet access), and the Internet can be accessed through broadband dial-up after creating a broadband dial-up connection.

2. If the WLAN is connected to the router, first check whether the port of the network cable and the network card and the port connected to the LAN of the router are in good contact, whether the network cable is normal, and if there is a problem, please replace the network cable. If you can connect normally, the LAN light will also be on, and there is no problem with the connection, please check whether the router has DHCP service turned on and whether the WAN port is connected to the Internet. If there is a problem, you can restart the router to reconfigure it.

Still doesn't work, try replacing the router.
