How to improve the speed of computer access network in LAN

1. Uninstall the network protocol that is not used

The existence of network protocols, network detection, which slows down the speed of the network, to speed up the LAN, you can uninstall the network protocol is not used, open the Network Connections window, right-click "Local Connection", select "Properties", and then in the open window to remove unwanted protocols. You can remove TCP/IP-dial-up adapters, Microsoft friendly logins, Microsoft Virtual private network adapters, ipx/spx compatibility agreements, and so on, because these components are not usually used, if they are selected, it will affect the speed of the computer.

2. Set Network card acceleration

NIC is a network communication equipment, if not to the maximum speed, it will waste the bandwidth of the network. You can press the Win+pause/break key, click the Hardware tab, and then click Device Manager to open Device Manager, double-click Network adapter, click the Advanced tab in the Open window, and select link Speed/duplex Mode (connection speed/ Duplex mode), and then select Full mode below it. This will allow the NIC to be tuned up to speed. Of course, if you are using a wireless network, it can be transferred to the highest speed, it is the author's wireless network card d-link airplus xtremeg+ dwl-g650+ Wireless CardBus

　　3. Remove unwanted equipment such as printing

The Automatically search for network folders and printers item is selected by default and removes it. In Windows XP, double-click Folder Options in Control Panel, click the View tab, and then scroll the mouse pointer to the bottom of the window to see a print-driven networking option, and when we print, Windows XP does not take the liberty of looking for a printer on a local area network and installing a driver to avoid accidentally hitting a confidential document on another department printer and not being able to find it. At the same time, after this item is removed, when we access the local area network computer through the "Network Neighborhood", it does not automatically find the shared folder on it, so it can also speed up the Internet in the LAN.

　　4. Cancel the login password

This depends on your situation, if the computer does not save sensitive data, just put some public resources, you can set up a blank password login. So that users do not need to provide a password to be able to enter directly, you can save the time to tell others the password, but also more convenient.

When setting, just press Win+r, enter Gpedit.msc, open the Group Policy Editor, find "Computer Configuration" → "Windows Settings" → "Security Settings" → "Local Policy" → "Security options", and then double-click the "Account in the right window": A local account with a blank password allows only console logons, and it is set to Disabled in the open window. Open Explorer on this machine, select tools → folder Options, click the View tab, and then cancel the small hook before removing simple file sharing (recommended).

　5. Automatic Login LAN

If you need to access a shared folder every day, you do not need to double click "Network Places" and then locate the server, double-click and enter your username and password to access it again. For example, you want to access a computer called server, user name, password is 8888. Just write a bat file in which you enter the following statement: NET use serveripc$ "8888"/user: "user", then drag and drop the bat file to " Start → program → boot "group, the system will be user for username, 8888 for password login server computer, so you access it anywhere on the above shared folder no longer need to enter a username and password.

If you are using Windows XP, you can select the "Remember my password" option after the first time you open a shared computer and enter your username and password, and you will not be asked to ask for a password on your next visit.

　　6. Use a faster firewall

Now many people have to install the Internet firewall, these software because to intercept a lot of network data, the general will be compared to consume system resources. So choose a good firewall software can also improve the speed within the LAN.
