First, if you used to be XP, now modify Windows 7, there is a drop in the phenomenon, then

First step, download and update your network card driver, if the brand machine, to the manufacturer's website to download.

Step Two, turn off the IPv6.

Some other students said that they would encounter a DNS-unresponsive problem, particularly in this list of solutions for Win7 routing Internet DNS servers that do not respond:

One, the four statements of problem symptoms

say one:

1. First you can start-run input cmd, and then enter ping 127.0.0.1

If ping is not a problem with the TCP/IP protocol please reload the TCP/IP protocol

2. Then ping your default gateway Gateway) Default gateway can be entered Ipconfig/all view ping to indicate that there is no problem with the routing settings ping impassability should be a routing problem

3. Network Diagnostics said the DNS server could not connect this could be a problem with a school DNS server if other students can surf the internet Did you forget to change the DNS domain name server to automatic access? If the other students can't get in contact with the school, tell them the DNS server has a problem.

saying two: (Status of ARP attack)

Workaround Run command ARP under one MS-DOS window- D after the internet can be restored.

Workaround Two first you install the ARP firewall, the second delete c:windowssystem32 NPPTools.dll system files.

saying three:

In fact, the Vista system itself is fundamentally poor compatibility and some system programs have automatic recognition function.

General Vista system computers will be able to connect the local network and the Internet are normal to use the diagnosis of Windows Network Diagnostics results are unable to communicate with the DNS (server number), while the packet sent and received data also has a certain gap .... Now the general computer maintenance personnel are unable to solve.

When set to an IP address, and so on, in a state of automatic acquisition. Network state is sometimes a connection state. But sometimes it can't be connected ....

These things like the internet for a few days, but after a while you can't connect to the Internet at all. Seemingly similar problems: when the computer appears to be local only, you use Network Diagnostics for diagnosis and repair to see if this problem has been repaired? When no longer go to the host on the IP again set, howeverAfter their own computer and then manually set the IP address and so on .... And see if it's connected ...

No more, you can call the brand computer after-sale maintenance staff to give some guidance.

saying four:

The system has more security concerns, your IP is set to automatically obtain the IP and related parameters from the DHCP server, but this process may be for some reason, not completed. In the SP1 era, in this case, the operating system in order to prevent the network (Microsoft wrote this), the way to set the network card 169.x.x.x reserved IP, do not make any error prompts, if more than one computer does not get the correct IP, then they can also communicate with each other through the reservation address.

However, after installing SP2, the operating system, based on the principle of security supremacy, does not allocate any IP, shuts down the network connection, and reports that the error local connection is restricted or connectionless.

The general situation is that the network card can not bind IP, sometimes fixes can be resolved, but many times the repair is not working, the reason is more complex, is generally caused by the network, and the system or the computer itself does not have a relationship, now enumerate the methods of troubleshooting:

Two, 8 methods for resolving and Troubleshooting

Method 1:

Open the Control Panel Network connection, locate the current local connection, right-click it, select Properties, double-click Internet Protocol (TCP/IP) on the General tab, and choose to use the following IP address. Fill in the IP address 192.168.0.1, fill in the subnet mask 255.255.255.0, others do not fill out, and then point to determine the problem can be resolved. (If the current computer joins a workgroup or domain, it will be set according to the situation.)
