No, it could be a problem with Netcom or Telecom, I've also had it, it's not poisoning.

I don't know if it's right!

Try the XP patch Maybe the patch is not up to date, and it should be okay after playing.

ADSL Internet access is not about DNS!

Take a look: Is there a browser set up**, set to cancel!

Newly install any software and uninstall it!

Old question. IE's problem. Uninstall from installation.

It's supposed to be a virus, let's talk about killing.

Start - Run - Enter cmd - OK - Enter netsh winsock reset, press Enter OK. Then reboot.

If it prompts that you need to be an administrator: that's because you don't have administrator privileges, and Win7 opens C: Windows System32.

Find, right-click to run as an administrator, xp is a similar method.

If the answer is helpful to you, thank you for your support.

What system is Enterprise Server Edition? Turn off all protection software and try it.

Maybe your host file has been changed.

Which is that web page? Can you send it to see? Maybe you don't have Flash Player installed

Basically, it's all malicious web pages, so it's best not to open them.

Check whether the wireless NIC is disabled (or the IP address is not automatically obtained).

Reinstall the system and ask for advice from a professional.

If you have Preferred Networks on the wireless network in your wireless card, delete all the preferred networks, and then reconnect to the specified network.

I suggest you reinstall the system.

You use 360 Repair to take a look at 360 Guardian - Web Shield - Browser Repair.

Clean up your computer with Kingsoft First Aid Kit, then uninstall the sound card driver and reinstall it! ~

Swap out the jack or update the sound card driver.

For now, you can check the router first; It has nothing to do with cats.

If you have a switch connected to your router, you also need to check the switch.

If your router and switch (in the case of a switch) are fine; Please check your network cable.

For unprofessional people, there is only one way to check the network cable; Change your computer to your current network cable.

If the network cable is fine, please check your computer's network card driver.

If the NIC driver is fine; Please check your network card.

There is another situation that will arise that you are currently having such a problem:

This is when your router is not compatible with your computer's network card. (The investigation of such a situation is: the computer changes to other network cables to access the Internet normally; The one that was connected by the route was originally connected to the computer, and the Internet was normal after changing the computer. )

In this case, change the route or change the network card of the computer!

Hope it helps!

Go to the router and enable DHCP. First, enter the router, (open the IE browser, enter OK in the address bar, OK if not.)

In the login box, fill in the username and password admin or guest. On the left is the menu, and there are submenus under those + signs. ）

In the settings interface of the router, find the IP setting option of the WAN port on the menu, there are static IP, dynamic IP, and PPPoE, select PPPoE dial-up, fill in the broadband account and password (password), there are "automatic connection", "on-demand connection", etc., select automatic connection, save.

Second, on the settings interface of the router, find the DHCP settings on the menu, select "Enable", and save.

Third, click the "Restart Router" button.

If you can't get on the network, you can directly connect the network cable to the cat to try it, in addition, when you can't get on the network, take a look at the lights on the cat, whether there are two lights flashing, if so, it should be a network problem, and your computer has nothing to do with it.

I also often have this phenomenon, sometimes I can't go up for a while, and then it's fine, or it's good, and suddenly the Internet is disconnected.

Do you turn on the router and see if it's connected? Open Run, enter cmd, and then enter the ping space, press enter to see if the connection between the router and the computer is intact and normal, and this should be the case.
