Windows system does not have a comprehensive solution for Internet

Software class issues

1, Vista can not access the Internet

The solution to this problem is simple, if your taskbar has a broadband connection icon (bad) then you can at the beginning (that is, the shutdown button above), there is a control panel, into which you can have an icon (icon style: Four PCs under a cable connection, the Chinese version is "Network Center "), into which he, on his left, has six options select the Sixth option (Manage network connections), enter, you will find two computer graphics, the first icon on the right button, select the bottom of the Properties button, in the pop-up box to find the words with Tcp/ipv4, point him, and then point him below ( There are three buttons in the last button that is the attribute, where you can adjust your IP address, tuned OK. Connect broadband to the top of the control surface version of the beginning, you can connect broadband.

2. Windows 2003 cannot surf the internet

1), open Registry Editor, delete the following two keys in the registry (before removing the best lead out of the backup):

Hkey_local_machinesystemcurrentcontrolsetserviceswinsock

Hkey_local_machinesystemcurrentcontrolsetserviceswinsock2

2, in the system directory of the INF directory to find Nettcpip.inf file, open, find:

[Ms_tcpip. Primaryinstall]

; TCPIP has properties to display

characteristics = 0xa0; NCF_HAS_UI ncf_not_user_removable

Change the 0xa0 here to 0x80 save exit (this setting is to allow users to modify the TCP/IP protocol)

3, open the "local Connection" properties--install--Add a protocol--from disk installation, find the Nettcpip.inf file just saved, press "OK", back to the list, select the last "Internet Protocol (TCP/IP)" (left no icon, note not that " Microsoft TCP/IP version 6 "), will prompt for no digital signature, press OK to install.

After this step, and return to the Network Connection window, this time, select "TCP/IP", the "Uninstall" button is already available (not done before this step is gray). Click the Uninstall button to remove the TCP/IP protocol and restart the machine.

4, restart, the Nettcpip.inf file, and then follow the 3rd step, reinstall a TCP/IP protocol (at this time it will not be prompted no digital signature, hehe).

5, the installation of a good agreement after the restart, reset the "local Connection" connection properties, you can network, if not, then restart again, hehe.

I deeply think that the problem is due to my hard disk aging, resulting in TCP/IP protocol related data corruption, so I hastened to the hard drive ChkDsk, hehe.

3. Windows XP does not have access to the Internet

I found that one of the most easily Windows XP is unable to access the Internet, many people have encountered such a problem, and do not know how to deal with, someone even had to reload the system, in fact, it is not difficult to solve the problem, first check the network connection does not have any icon to explain the problem. The Device Manager can find the explanation that the NIC exists. Initial judgment is the network card contact bad. First, check the Wire crystal Head and network card contact is firm. Second, check the network card and whether it is plugged in, it is best to plug it again. Mainly look at the following two aspects:

1 Some people are connected with the problem, such a good solution, as long as in the IE tool--internet option-Open the Connection tab click Settings, re-enter the password after the confirmation.

2 If the above method can not be resolved, in the case of ensuring that there is a network card driver (there are many network adapters do not install the driver, Windows XP will automatically install the driver), simply enter the control panel-System-Hardware tab, click Device Manager, the network adapter uninstall (do not uninstall 1394 network adapters) Then click OK, reset the system, so that if Windows XP recognized your network card, will automatically install the driver, Windows XP can not identify, will prompt you to install the driver, just install good driver, will solve the problem. Some network adapters after the driver, the system to scan for a long time, after that, the lower corner will also appear with yellow exclamation mark connection icon, which requires you to set the IP address, the method is: Double click the icon, in the dialog box to click on the properties, in the General tab out of the click on the Internet Protocol (TCP/IP), Click on the properties, select the use of the following IP address, in the IP address to fill in 192.168.1.X (X for any number of 2--10, and then click the screen Mask, The system will automatically generate 225.225.225.0, and finally click OK to close this tab, click OK to close the General tab, your network will be able to connect again.

4. No Internet access after reloading system

You start to open MS-DOS, the online network of the input "ping 192.168.1.1" to see if there is no pass (that is, there is no: "Reply from 192.168.1.1:bytes=32 time=1ms ttl=255" Similar language, there is a pass), If it means you are through the cat to the Internet, set your route on it.

If you are using dial-up software on the ping impassability, not on the network may be triggered by software, reload dial-up software can be.

5, installed on the dual system can not access the Internet

Windows Vista and Windows XP dual systems may appear to be unable to access the problem, this problem is generally unrelated to the dual system, the problem should appear in the TCP protocol.

• First enter the command line mode, enter CMD, at the command prompt, enter "ping 127.0.0.1"

To determine whether the TCP/IP protocol is installed successfully, do not general reinstall the TCP/IP protocol, if the general rules into the next step.

• Enter "ipconfig" to obtain the local IP address and gateway address, through the "Ping native IP address" to determine whether the network card problem, if the ping does not pass, you need to reinstall the network card driver, if the general rules into the next step.
