High score Urgent A problem of not being able to access the internet

You don't have to continue routing and then dial up the Internet.

That's the problem!

In fact, you cancel the router, and then directly connect the network cable output of the network card directly to the cat, and then dial up the Internet!

If you still can't get up, then you can make a new connection!

The way to make a new connection is simple.

First of all, open the control panel 'Network Connections' and on the left there is Create a new connection.

Tap it. Then the next step is to select the second option to manually set up my connection next.

Then select the second item Connect with Username and Password Required Next.

And then you can just write a name, like a broadband connection.

Then enter your username and password in the next step! Then the next step and then the completion is to note that your username and password must be correct!

If you can't get online, maybe your cat is hanging

The fault is that your network card is broken.

1）.The computer that is turned on is connected to the Internet through the router. In this case, there should be no need to modify the configuration, if your computer still prompts some errors, it is estimated that it is infected with a virus or the system file is corrupted, it is recommended to disinfect or repair the system file, and reinstall the operating system when the above methods are invalid.

2）.The computer that was turned on did not pass through the router and was directly connected to the Internet cable. At this time, you may need to modify the IP protocol configuration in the network connection (however, each network operator has different Internet connection methods, some through static IP, some through dynamic IP, and some through some encryption protocols, such as PPPoE), and you can consult the relevant network operator for specific configurations.

678 is a line fault.

You just go to the route, use a computer to connect the modem, try it.

Of course. You used to use the route yourself, and the route is set up, and then you don't need to dial the main wash and dial the number in the background when you have a request to access the Internet. If you use dialing, you can also let him dial the number automatically, and the next ADSL dialing king will become.

It can also be achieved with the system's own functions, which is the trouble point. Let's not talk about it.

Since it's all broken down a computer, then dial up directly to surf the Internet, no need to route If you're picking up someone else's, refresh the router, on the router, a small hole, and hold it down with a needle for about 15 seconds.

Then set your account password again.

Since it is a common router for two machines, then go directly to the router and dial it up. If it's not the problem, reinstall the system (no way). In addition, the same as above, mobile phone Internet access is actually not expensive, the most important thing is that the network speed is slow, but it is still capable of coping with QQ.

You can only reinstall the system.,Another good way to teach you.,You can also chat QQ with your mobile phone to surf the Internet.,Two dollars a day for Internet access.,Then you don't have to be afraid of expensive phone bills.。

Reinstall the system to see.,No, I think it's supposed to be the system poisoned.,You can buy an XP disk.,Follow the prompts to reinstall it.,It's relatively simple and simple.。

678?The bad computer is definitely the server, and 678 is no signal. Find the maintenance department + RMB, OK!

Error 678 is a line issue. Let's see if the adsl and phone wires of the splitter are plugged in incorrectly.

Or the driver of the network card.

System files are missing.

Reinstall the system. Or copy the file back from another good machine and put it in its original place.

Listen to what you say, I think it should be the system poisoned, you can buy an XP disk, follow the prompts to reinstall it, it's very simple.

Error 678? Generally, the remote connection is wrong, and the network card is not good to make it flow.

1) If it is a problem with the broadband itself, first directly connect the broadband network cable to test, if it is a broadband problem, contact the broadband customer service to solve it.

2) If it's a problem with the router, if it can be used originally, it can't be used for the time being, my own practice is to disconnect the power of the router and plug it in, and I'll take a look. In there is a factory reset, from the new strict according to the manual settings can be used, I don't understand, it is not recommended to set it at will (this is under the premise of the correct physical connection, sometimes the router is slow or failed to find the IP address, not that the router is broken).

If it can't be solved all the time, it is recommended to call the customer service of the router, they have **** guidance, I encounter a problem that I can't solve by myself, it is very useful to consult the advice they gave, and they will give the correct advice for your settings or operations.

3) If you turn off the wireless switch, turn it on, if it is a wireless connection with software, it is normal for the software to be difficult to use and often have problems, there is no better way, use a router. In addition, it is caused by the network card driver is not or is not suitable, and whether there is a problem with the network cable interface or network cable.

4) If it is caused by a system problem, it is recommended to restore the system or reinstall it.

First of all, you need to know if the router's DHCP service (automatic IP address assignment) is turned on

It is generally caused by IP address conflicts, so it makes more sense to confirm the network environment and then talk about it.

If the router is abnormal, reset the key as soon as possible, at this time the router has been restored to the factory default, and it needs to be set again.

First of all, it is necessary to keep the front-end equipment (modem) intact and the network unblocked.

After pressing the router's reset button, wait until all the lights are on together, indicating that the reset is successful.

Enter your IP address, username, and password in the address bar of your browser (prompted on the back of the router).

After following the router's setup wizard, you can surf the Internet normally.

Resources.

Don't worry about it, as long as the hardware is not broken, just reinstall the system.

Can other software that requires the Internet to be used normally?If you can say that the browser is broken, you can go down again, if other network software can not be on, first disable your home network card and then enable it, if not, it depends on whether your network has done IP settings, if it is fixed, you have to set it, if it is a dynamic IP, there is no network, it is recommended to search for a network reset, maybe it will be good.

Fix it with 360 and something went wrong with DNS.

Probably:1The network cable is disconnected. Check the crystal head and test the network cable.

2.The switch itself in the building is broken, or some ports are damaged, and the computer room is out of mode. You can report to the network business for repair.

3.Oxidation and damage to the laptop port. Oxidation can be turned off and scraped with a blade.
