3. How do I connect my laptop to wifi?

There are two ways for a laptop to turn on the physical WiFi switch.

1, FN+ The function key area has a wireless tag key (combined function) which is turned on when pressed;

2. Some notebooks (such as IBM) have a physical button on the body that can be opened.

Note: If you still can't connect to the network after both methods are turned on, then check whether the wireless in the local connection is disabled (gray), and right-click to enable it after finding it. If the WIFI function is turned on correctly, a wireless icon will appear in the lower right corner (just like an I plus three arcs). Click Open, and a WIFI list will appear. Find the device you want to connect to and enter the password.

The method for connecting the operating system to the WiFi includes the following steps:

1, you need to create a wireless network link, enter the Win7 start menu in the lower left corner of the desktop, and click "Control Panel".

2, and then click on the "network and interest"

3. Next, open the "Network and * * * Enjoy Center", which is a function that Win7 computer networking must use. Whether connecting to a wireless network or a broadband network, you need to turn on this function to set it. There are also shortcut keys, which can be opened by clicking the shortcut key like a window in the lower right corner of the desktop.

4. Click Set up a new connection or network.

5. Select "Connect to Internal"

6.Win 7 will automatically search for the corresponding wireless network, click "Connect" on the network with the best signal and enter the password. If no password is set for this wifi. You can connect directly to the Internet.

Notebook of Win8(Win 10) system connected with wifi:

Windows8(Windows 10) has made great changes in wireless network connection, abandoning the traditional pop-up window and using the right sidebar for network connection.

1, click the network icon in the tray, and check whether the flight mode is turned on in the right network sidebar that pops up. If so, you need to turn it off. Then find the private wireless network SSID (wireless network broadcast name) in WiFi, and click "Connect".

2. Enter the security key of the private wireless network in the white box. If you are worried about the input error, you can click the eye icon on the right to check the input, and then click "Next" after confirmation.

3. If the network security key is entered correctly, the computer can be connected to the network through the wireless network and can be used. Of course, there is a final step in wireless network connection, whether to enable * * * sharing between computers and connect devices on this network. Generally, if two or more computers are connected to the wireless network and need to enjoy files, printers and other devices, click the second item "Yes, enable devices that share and connect to the home or work network", otherwise click the first item "No, do not enable devices that share or connect to public places".

Precautions:

If you use wifi at home, try to set the wifi password more complicated, which can prevent others from surfing the Internet and lead to the problem of slow Internet access.

4. The laptop is connected to the wireless network. How does it connect to broadband?

You can remove the route and connect directly to the computer, or you can connect the cat directly to the computer. In addition, you should set it on the computer. The specific steps are as follows:

First, determine which way you need to access the Internet (dial-up or routing). Dialing means that you have to double-click the dialing software to access the Internet. Routing means that as long as you enter the system, you can automatically connect to the network without double-clicking the dialing software.

I. Dialing

1. Start-Settings-Control Panel-Network Connection-New Connection Wizard-A dialog box appears-Next-Select Connect Inter- Next-Select Manually Set My Connection-Next-Select Broadband Connection and Connect with User Name and Password-Next-Enter what you want.

2. Double-click the newly established "Broadband Connection" icon before surfing the Internet in the future.

Second, routing.

1. Make sure your cat has routing function, determine your cat's IP range, and ensure that your network card and the cat's IP segment are consistent (generally,192.168.1.1to .255).

2. Fill in "192. 168. 1" in the address bar of IE and press enter. If your line connection is normal and the network card driver is installed correctly, you should be able to access the cat at this time and the login window will appear. Please refer to your cat manual (usually admin 1234 or admin admin) for your user name and password.

3. After entering the cat interface, select "routing" as the mode, "pppoa" as the package and "LLC" as the multiplexing. Next, fill in the corresponding items in your account password, confirm, save and exit.

4. Open IE and you should be able to surf the Internet.

In addition, there is no difference between dialing and routing, but from a security point of view, dialing is safer, that is, it is more troublesome to dial every time you go online. The advantage of routing is that multiple computers can surf the Internet at the same time (another hub must be configured), but not multiple computers.

In addition: I advise you never to use the "Star Speed" software of Telecom! It is a very overbearing junk software, which will bring you unlimited trouble. Just use the system itself.
