Problems with Windows 7 system computer networking

Target. Yes, after installation, click on "Trojan Killer" to use the quick scan function, which can also fix other system errors and kill Trojans.

You can also use the manual protocol (provided that there is no virus in the system) (it is recommended to use Kingsoft Guardian to solve the problem).

1. After opening the desktop "My Computer" or "**Site" or "My Documents", then click the up button and run to the desktop, you will find that there is a deleted Internet Explorer icon inside! Just drag it to the desktop.

2. Right-click on the blank space of the desktop, select "Properties" in the pop-up menu, pop up the window, switch to "Desktop", and then click "Customize Desktop", you will find that there is no Internet Explorer in the "Desktop Icon", then press the letter key I, and click "OK" all the way. How's that for now, the IE icon appears on the desktop, right?

3. Create a new folder, such as D drive or E drive, and name it Internet Explorer(Note that this method cannot be implemented directly on the desktop), after the establishment is completed, copy this folder to the desktop, how about it, the desktop will immediately appear IE icon! The new Internet Explorer icon is back!

4. In the run box, enter "Open the registry and find the following registry branch: hkey current user software, Microsoft Windows Currentversion, explorer, hidedesktopicons, newstartpanel, and the dword (32-bit) registry key named ""; set its value to "0"; After refreshing the desktop, you can see the disappearing IE icon reappear, and you can see the relevant Internet browsing settings when you right-click. If you don't have a new one named "", create a new one yourself.

5. Use the key combination ctri+alt+del to open the task manager, see if there is this process, if not, enter in the "create task" and press OK, if you can find this process in the task manager, then you can delete it first, and then enter it in the new task, OK.

6. There is a little trick oh, if you accidentally delete the IE icon on the desktop, it is not easy to fix it, I have tried to repair IE, reinstall IE, copy from other computers, etc., but can not achieve it, a coincidence I found the following method, I think it is really a classic, and share it with you: Click Start - Run, enter the following: reg add HKCU Software Microsoft Windows CurrentVersion Explorer HideDesktopIcons NewstartPanel v T reg Dword D 0 F Absolute Classic!!

If I'm not mistaken, you're using PPPoE. You don't need that kind of software, window7 comes with it.

2. Find "Manage Wireless Networks" on the left side.

3. After entering, there will be a series of operations, select the wireless network you want to manage, and operate.

There is a wifi connection and a network cable connection.

What the hell is this?

You click Diagnostics.

Click the network icon in the taskbar, and then click Open Network and Sharing Center--- set up a new connection or network, and follow the steps.

The computer installs the network card driver, and the network cable can be connected to the network.

1.Plug in the network cable: The network cable is inserted into the network cable port of the laptop, and a such icon will appear in the lower right corner of the notebook, if there is no exclamation mark, the network has been connected.

Select the wireless network you want to connect to, click Select Connection, and enter the account password to achieve WiFi connection.

You can open the Network and Sharing Center in your Control Panel, select the New Connection Wizard, click "Set Up Wireless Temporary Computer to Computer Network" at the bottom of the pop-up page, and then click Next to set the network name and password. Then you need to set the IP address and gateway of each computer, the IP address of each computer cannot be the same, but the gateway address must be the same. And you have to turn off the firewall on your computer.

This way, your computer acts as a wireless router, and other computers search for the wireless network you set up and connect to it.

It may be a problem with the ** machine, and the following is an example of how to solve it.

One day, my good friend said he wanted to surf the Internet at home. It's not easy, it's a little bit to me. I bought a regular built-in modem and took it to a friend's house and disassembled it and installed it.

Next boot the system, find the new hardware, install the drivers, and it goes very smoothly. Then pull a ** cable from the ** machine interface and connect it to the line plug of the modem. However, when I opened "My Connections" and dialed out to surf the Internet, there was a problem.

I can hear the trumpet sound, but I can't get on the Internet. Once in a while, the speed is only about 20k, which is too slow.

Later, I found that when dialing the number with win98's built-in dialer, if you dial the "114" number, you can hear the dual audio signal sent by the modem not three, but four or five tones, so you can't dial the 114 number at all. What could it be, is the modem broken! New?

Hands don't go back like that! Is there a problem with the line? I started to think, I checked the ** line, directly from the outdoor lead to the indoor ** machine, there is no joint in the middle, and there is only one ** machine.

I've used it at my friend's house, and the call works very well. It can't be a matter of the line?

In desperation, I had to unplug the ** machine and only let the modem connect to the ** line. I opened "My Connections" and typed 163, clicked on Connect, and after only three familiar calls of trumpets, the modem started to bark. It passed, and within ten seconds, it went online.

I opened the web page and it was very fast. After taking a look at the speed of more than 53k, the speed is quite fast. In order to find out the reason, I connected the ** in the ** line, and then dialed the number, but it was still wrong, and it couldn't be pulled at all.

Remove it, pull it out. I had to tell my friend that I unplugged the *** machine when surfing the Internet, which may be the poor quality of the ** machine.

Later, another friend asked me to help him install a modem. The result is the same problem in the end, the Internet speed of the ** machine is dead slow, more than a dozen k. Unplug the ** machine, and the network speed horse rises to 54k.

I just remembered that the two friends used caller ID machines. Caller ID ** has to accept the caller ID information sent by the switch during the ringing period, and its line interface is definitely different from that of ordinary ** machine. So I am here to remind netizens that when installing a modem, if you can't connect to the Internet, just unplug all the ** machines in the line and try it, maybe it will solve the problem.

I hope I can help you with your doubts.

1. You can use the driver disc you brought when you purchased the machine to install the complete driver.

3. Use third-party software to update drivers.

2. Find "Hardware Detection" in the toolbox.

3. Click "Driver Installation" in the hardware test.

4. You can see the "installation status", if it is not installed, you can click to install it directly.

Maybe it's because the network card driver is not installed.,Just install it with the driver installation software that comes with the machine.。

There are a few ways you can try it:

2. Re-establish a broadband connection and re-dial;

3. If the above methods are not possible, it is recommended to repair the system, it may be caused by the lack of files when restoring.

The error of one-click restore on the computer may be caused by a corrupted program or backup file, and now you need to make the correct method and tool to continue reinstalling the system until it is successful.

Solution: There are several ways to reinstall the system, and you can choose one of the following operations.

Hard disk installation: If the above operations are invalid, press the F11 key or F8 key after booting or restarting, and see if there is a one-click ghost installed (if not, you can "one-click restore" as a keyword search**Install the concise software, and run the program after the system is reinstalled or when it can usually run normally, select "Backup" and wait for it to restart and save the current normal system in the non-system partition of the hard disk in gho file format, so that you can restore it at any time when there are system problems in the future), If you have one-click restore, press enter to confirm, enter the one-click restore operation interface, and then select "Fight early" to confirm. If you have performed a one-click backup when you first installed the device, you can restore it to the state in which it was backed up.
