The network connection is gone, and the little brother kneels down and begs everyone.

It should be a problem with the network card.

Check the task manager to see if there is any problem with your network card.

You want to install a driver for the network card.

My home is also connected with a road tour, and there is no need for a network connection at all, are you an XP system? If so, then you don't need it at all, because you're not the host, so as long as you set up the IP, you're connected, is it another computer (connected to you) network is not good or there is a problem with the ** line.

In"Online neighbors"- Properties - see if there is"Local connection"If you don't have it, it's a problem with the network card, then change it quickly, and it's not expensive.

If according to what you said, your system is win7, then you can't access the Internet should be caused by the computer can not get DNS, not just the IP problem, there are several solutions, one is that you can run the dos command, check your company's gateway, IP and DNS, and then change the IP, set it to your notebook, there is another way, win7 system when connecting to the local area network, there will be a network choice, you had better choose the home network or office network, And don't choose the public network, if you choose the public network, in many cases the Internet will be limited by win7, that is, the network icon in the lower right corner of the computer will have an exclamation point, and can not automatically obtain IP and DNS, so it leads to not being able to access the Internet, both methods, you can try, I hope you succeed, hehe.

First of all, you need to make sure that your local network card is good. After plugging in the network cable, point start, run, enter ipconfig all to see the working status of all network cards, if you can not even see the local connection after entering, it proves that your network card is broken, if there is, it may be that your network cable head is broken, in short, check your book, the network cable is fine.

Judging from the phenomenon you described, your company's LAN may have done MAC address filtering in order to restrict external access, and finding a MAC address spoofing software can deceive the route, of course, it is best to find a network administrator to add MAC address permission.

Your company's server should have an account, you should call your company's network technician to solve the problem, your company's network must be managed, like this situation is generally OK to have an account

The IP gateway and DNS can be viewed by themselves. Right-click on your LAN computer to see the details!

Start - Connect to - Show all connections - (look at the connection icon that needs to be enabled, if it is gray, double-click to enable it).

If it is not enabled, check for Trojan viruses and clean up the plug-ins to eliminate these effects.

Then try to uninstall the local network and wireless network drivers, and reinstall these drivers, taking care to prepare these drivers in advance.

Create a new one yourself, check the network connection with your online neighbor, "create a new connection" and then do it step by step.

Needless to say? Something must be wrong with your desktop. If your laptop can access the Internet, it means that there is no problem with your network, and the problem can only be with your desktop. It is recommended that you move your desktop to a friend and try again.

As you say, the point has been taken away.

Since you can go on for a while, it means that there is no problem with the setting.

The possibility of a virus cannot be ruled out.

I've seen the same problem, and the port automatically drops. The other mouths are completely fine (campus network). Later, I changed the network card.

The network port of the network cable line or route is faulty.

Look for the fixed IP set and see.

Let's try to take someone else's computer and take a look.

If the same. Do you adsl home internet access?

Are there any problems with the device (performance)?

You don't have M at home because your broadband is light to enter the home and you don't need ** online Internet access As for the 629 you asked, first of all, what system does your computer have, if it's xp, you need to reinstall a dial-up software It's a broadband connection If it's win7 or vista, first build a broadband connection and then run it as an administrator Generally, this error refers to the fact that the IP you change from this computer to another computer is not compatible Because Unicom's broadband is automatically obtained IP is different every time you try.

win7 local connection is not enabled prompt 651 does not prompt the landlord to say 629!

It is recommended that the landlord recreate the broadband connection, if it does not work, or if the Internet access from the desktop to the laptop often appears 629, it is recommended to reinstall the laptop network card driver, or change the working mode of the laptop network card to 10m full duplex.

1.Create a broadband connection (no shortcut!) ）

2.Change the NIC working mode.

3.Reinstall the NIC driver.

Are you using cell broadband, your previous computer should not need to enter and password, how to use it, how to use it now, you use the way to enter the password to access the Internet means that you and the telecommunications signal between only a modem when you use the dial-up, from what you said, your network should have a router in other places, you can directly set the computer to automatically obtain IP.

Connect your computer separately to the Internet and see if you can it should be telecom setup! And remember to check your network card, network cable, and finally try another one.

Can't open IE or can't open a web page?

What does all web tools mean.

Try pinging it and seeing.

Like ping to see if it can be pinged.

The network is like this, just take an analogy, why the configured machine in the Internet café must be equipped with a poor sub-network speed? You will definitely say that their Internet café has adjusted it themselves, in fact, it is not, because the reality is like this, the worse the configuration, the slower his network speed is, of course, you can try to change the route, so that it can be divided equally, that's good, you know what I mean?

Try it out with your machine's ping route.

You turn on Universal in Settings'''There is a restore in the generic'You click Reset Network Settings to try'My ** also has this problem'It's good after restoration'

Try restoring your appearance settings.

Mine also had this problem......
