How to improve computer network speed in LAN

How to improve network speed seems to have become our consistent demand, when the method has a lot of, this article collated some, the needs of friends can learn from, hope to help everyone

1. Remove irrelevant options

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 an auto search network folders and printers item, which is selected by default and removed. In this way, when we print, Windows XP does not take the liberty of looking for a printer on the LAN and installing the driver, to prevent inadvertently the confidential document to the other Department of the printer and its own windows7 system download but can not find. At the same time, when we remove this item, when we access the local area network computer through the "Network Place", it does not automatically find the shared folder on it, this will increase some speed.

2. Tune the NIC to full speed

The hidden content of this post needs to be replied to be able to browse

Press the Win+pause/break key, click the Hardware tab, click Device Manager to open Device Manager, double-click the appropriate network adapter under net Fit, and in the open window, select the "Advanced" tab, and check the link Speed/duplex Mode (connection speed/ Duplex mode), and then select the next full mode. This will allow the network card to be tuned up Of course, if you are using a wireless network, it will be transferred to the highest speed, Ghost XP SP3 is the author's wireless card D-Link airplus xtremeg+ dwl-g650+ Wireless Cardbus Adapter # 2, the author sets its desired basic rate set (base speed) to 54Mbps.

3. Eliminate irrelevant protocols

Open the Network Connections window, right-click Local Area Connection, select Properties, and then remove the unwanted protocol from the open window. If you use Windows 98, you can remove the TCP/IP-dial-Up Adapter, Microsoft friendly login, Microsoft Virtual private network adapter, ipx/spx compatibility protocol, and so on, as these components are not normally used, and if they are selected , it will affect the normal access and browsing of workstations.

4. Set the blank password login

If you don't have sensitive data saved on your computer, just put in some public resources, you can set up a blank password to log in. So the user does not need to provide a password to be able to enter directly, can save the time to tell others password, but also more convenient.

Press Win+r, enter Gpedit.msc, open the Group Policy Editor, locate computer configuration → Windows settings → security settings → Local policies → security options, XP then double-click Accounts in the right window: A local account that uses a blank password only allows console logons, which is set to Disabled in the open window.

Next, open the 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. Automatically log in to the LAN

If you need to access a shared folder every day, you don't have to step through your network Places and then find the server, double-click and enter your username and password to access it again. For example, you want to access a computer named server, the username is user, the password is 8888. Just write a bat file, enter the following statement: NET use serveripc$ "8888"/user: "User", and then drag and drop the bat file into the " Start → program → start group, so that a boot, the system will be user name, 8888 password login to the server computer, so that you anywhere access to it on the above the shared folder no longer need to enter the user name and password.

If you use Windows XP, you can select the "Remember my password" option when you enter your user name and password the first time you open a shared computer, and you will no longer be asked for your password on the next visit.

6. Canceling the firewall

If you have enabled a firewall in Windows XP and shared a drive, it is possible that others cannot browse the shared drive in your network Places, you can right-click Local Area Connection, select Properties, click the Advanced tab, click the Configure button, and select "Off (not recommended)" in the window that opens. Items can be. Because our LAN computer itself is connected to the router, you can consider setting up a firewall on it. In this way, the machine inside the LAN will not be attacked by the outside world, but the machine access within the LAN will be faster.

7. Multi-system quick access to each other

If you find that Windows 2000 machine Access 98 machines are particularly slow, you can press WIN+R on the 2000 machine, enter "Regedt32", and find [Hkey_local_ in Registry Editor] Machinesoftwaremicrosoftwindowscurrent Versionexplorerremotecomputernamespace], find and delete the key under this branch, then double-click the 98 colleague's machine will be very fast.
8. Fast Backup/Update data

If you often need to back up your data to a file server on your local area network, do you want to check the files on your hard disk and switch to the file server? It's too much trouble. In fact, as long as we know the name of the file server (such as FILE_BCK) and know its username (such as user) and password (such as 123456), we can now just run a batch file, the content of this batch file is as follows:

Set Source=d:work

Set Dest=file_bckbackup

NET use file_bckipc$ "1234"/user: "User"

xcopy%source%%dest%/e/v/r/y/z

Save it as Batchcopy.bat, and later double-clicking the bat file will back up all d:work files to File_bckbackup.

9. Quick Map Drive letter

Open the root folder of the shared machine, such as HOMEPC, then select the appropriate folder, right-click, select the "Map Network Drive" command, you can immediately map the folder into a drive letter. If you select tools → map network drive directly, then we need to select the mapping path.

10. Cancel the unused network drive

If you mapped a network drive and no longer use it later, be sure to open Explorer, click tools → disconnect network drive, and then cancel the drive in the window shown in Figure 13. Otherwise, the disk will be mapped automatically each time it is powered on, and it will take up more system resources, thus slowing down LAN access.

11. Consider a shortcut to access a shared folder

If you frequently want to access a user's shared folder, such as Homepcwritingsoft, you can open Homepcwritingsoft in Explorer, then drag the folder icon from the Address bar to the desktop, and then release when the cursor becomes a link. Later, to access this folder, Ghost XP just double-click the desktop shortcut, no need to go from "My Network Places" in the layer.

12. Type the computer name directly

You can quickly access the computer that contains the shared folder you want to connect to, or the network path of the shared folder, in the Address bar of the explorer. If you enter comp (where comp is the computer name), enter the computer with the name comp to view its shared folders or files. Entering Compshare will enter the share shared folder of the comp computer.
13. Direct IP Access

If you pin a shared computer's network card IP, you can access the computer by entering the computer's IP directly in the Run window without having to open it from the Network Places layer.

14. Quick access under Total Commander

When you open a shared folder in total Commander, double-click its pane to pop up a window and select Add Current folder to add it to the Folder list. If you want to access it later, simply double-click the pane and select the appropriate item to get there quickly.

15. Dynamic/static IP two suitability

If you use DHCP at your company and you use a fixed IP at home, it is a headache to repeatedly modify the IP address of the NIC. If you install Windows XP, you can have the network card have both a dynamic/static IP: Double-click the Network Connection icon in Control Panel, and then right-click the appropriate network adapter, such as wireless network connection, select the Properties command, and then in the open window select the Internet Protocol (TCP/IP) item , click the Properties button below. And in the window that opens again, select the "Get IP address automatically" and "Get DNS server address automatically" entries. Click the Alternate Configuration tab, and then in the Open window, select the User Configuration item, in which you enter a fixed IP address, subnet mask, default gateway, preferred DNS server address, such as 192.168.0.188, 255.255.255.0, 192.168.0. This way, when our computer discovers that DHCP is present, it obtains an IP address from the DHCP server. Otherwise, we set the fixed IP, subnet mask, default gateway, preferred DNS server address, such as 3366 small games, such as 192.168.0.188, etc., very convenient.

16. Canceling Cache Settings

When you right-click a folder on your computer, select Sharing and security, click the Cache button at the bottom of the window, and then cancel the "Allow files to be cached in this shared folder" entry in the open window. This way, when the files under our shared folder are very long, it is obvious that someone else will be accessing this shared folder faster. If you do not, you may not be able to open files under this folder for a long time and may cause the system to crash.
17. Consider gigabit NICs and 64-bit PCs

Gigabit network card and 64-bit PC, and install 64-bit Windows, according to authoritative authority testing, its LAN speed access speed has significantly improved.

18. Place the wireless ap/router in the middle of the room

The wireless ap/router is the center of the wireless network, so be sure to put it in the middle of the room so that all the network cards in your home are better connected to it. There are a lot of people because the community broadband only to the door to the living room, will be wireless ap/router in those locations, so that your wireless signal will lose a lot, natural speed can not go up.

19. Turn on wireless 54Mbps mode

Some wireless ap/routers in order to "compatible" with more network cards, and does not open its G mode, at this time to log on to the ap/router, its "wireless mode" set to G mode (g), the "transmission (TX) rate" set to 54Mbps, activate 8X mode, and "Antenna transmission power" Set to the highest.

We'd better not use the Windows XP Wireless management, but install the network card comes with the program, so that when set, there will be more options, display is the author's network card self-contained program settings, there is the corresponding 8X mode, and can be forced to 54Mbps mode, these features Windows None of the universal wireless management drivers in XP.
It is important to note that, after forcing 54Mbps, in some PCMCIA slots on the wireless card may appear not connected to the wireless ap/router phenomenon, only the ap/router back to Mixed mode (mixed mode).

20. Changing channels

In a wireless ap/router, we can change the channel. For 802.11g, there are 11 channels available, but only 1, 5, 113 are not disturbed, that is, the same area using more than three 802.11g wireless network will interfere with each other, the overlap between the channels will make the data link rate decreases. Therefore, whether or not our neighbor installs 802.11g wireless network, or replace it with one of the above three channels, it may also bring some help to the speed and stability of the network.

21. Wireless/Wired Hybrid

Now the purchase of wireless ap/router will generally have 4 wired network interface, you put a large number of data access machine through the wired network card and network cable to connect it to the wireless ap/router wired interface, while the cable network IP address to remember. In this way, you in the other room on the machine with the wireless card, press WIN+R, enter the IP address of the wired network card to access the computer speed will be much faster! The rate of transmission between the wireless card and the wired card is very slow!
