Wireless Internet access is now a popular Internet access method. Without the limitations of Network cables, is it more free to access the Internet ~~~ (Feeling ). We usually use mobile phones, netbooks, iPad, itouch, and laptops for wireless Internet access. Can desktop computers also access wireless Internet? The answer is yes. Next we will talk about how to enable wireless Internet access for desktops. (Wireless Internet access referred to in this article mainly refers to Internet access through WiFi hotspots ).
Glossary
Wireless Internet access------- Baidu encyclopedia explained to us that wireless Internet access is divided into two types. One is to enable the data function through a mobile phone and enable wireless Internet access through a computer through a mobile phone or wireless network card, the speed is determined by the use of different technologies, terminal support speed and signal strength. Another wireless Internet access method is a wireless network device. It is a wireless Internet access method based on a traditional LAN and built on Wireless AP and wireless network card. Generally, as long as the internet terminal is not connected to a wired line, it is called wireless Internet access.
Here we will talk about wireless Internet access.

STEP/Method
-
- Our average desktop computer does not have the wireless reception function, so we need to install a wireless receiving device for the platform. The first thing we need is a wireless network card. Wireless network cards can be divided into two types: internal and external, such:(To avoid the suspicion of advertising, I blur the NIC brand)
This type of NIC requires you to open the hosts box of the server, install the NIC in the idle PCI slot, then install the hosts box, and then install the NIC Driver. This requires the user to have certain hands-on capabilities, because such a NIC has an external receiving antenna, so the signal reception capability and signal stability are good. However, for those brand machines that have not been protected, the portable boxes of some brand machines are labeled with laser fragile labels. If the chassis is opened, the warranty will not be guaranteed, therefore, we recommend that you use the following external USB network adapter.
- the external wireless network interfaces are usually USB interfaces. As shown in the following figure, although the shapes are different, they are always different.
This is similar to a USB flash drive, but it is larger than a USB flash drive, and it is a built-in antenna. Now the USB wireless network card is getting better and better. This is a receiving antenna that can improve the signal reception capability. This is also with a receiving antenna, the style is still very nice.
for a USB-type wireless network card, you only need to insert the network card directly into the USB interface, then the system will find the new hardware, and then we can install the driver.
- after the USB is inserted into the USB port of the host, the system will prompt you to find the new hardware, the driver installation interface is displayed (the built-in wireless network card of the PCI interface is also like this. After the device is installed and started on, the system will prompt you to find new hardware). It is generally not recommended to automatically install the driver, select the "Install from list or specified location (advanced)" option. Then, if the driver is on a CD, you can use the "Search for removable media" option, if the disk has been copied to the local disk, select the "include this location in the search" option and click "Browse" to select the path, next, the system automatically installs the driver. Click Finish.
double-click the Wireless Network icon in the lower-right corner of the system to display the wireless network connection. (Note: If the service in your system: Wireless Zero Configuration is disabled or disabled, the wireless network connection is unavailable, you need to go to control panel -------- management tool ------- to find this service in the service, then enable it and set it to auto start. ) then, some wireless signals (if nearby) appear in the list of selected wireless networks ), these wireless signals are generally sent through a wireless router connected to a broadband network. Wireless routers are also an important part of wireless networks.
I will not elaborate on the wireless route settings here. You only need to connect to the power supply, plug in the network cable, and log on to the settings window on the web page, set the user name and password for the bandwidth according to the setting wizard.
double-click the target you want to connect to, and the connection is automatically attempted. This warning is triggered when the connection is established for the first time. We chose to connect. After the connection, we can basically access the internet ~~ Hoho.
If the network connection fails, check ipsettings and NDS settings as follows: Control Panel ------- network connection ------ local connection ----- (right-click) properties -------- Internet Protocol (TCP/IP) ------- properties after the setting page pops up, you can set your own IP address (generally set to automatic) and DNS (we recommend that you enter the DNS server address of your broadband carrier for smooth browsing)
- Finally, we will briefly introduce how to use a 3G network for wireless Internet access.
3G Internet access is followed by GSM, GPRS, edge after the new technology, one of China's three major operators China Mobile is using proprietary TD-SCDMA, speed up to 2.8 m; China Telecom uses CDMA 2000 technology, now sets up evdo rev. a's network speed is up to 3.1m. China Unicom uses mainstream international WCDMA technology, and the theoretical speed is up to 7.2m. the speed is quite good, that is, the cost is relatively expensive.
The shape of the 3g usb wireless network card is similar to that of the above USB network card, but a 3G mobile phone card is inserted in it. The installation is also very convenient. After inserting it into the USB interface of the computer, place the attached cd in the optical drive to install the driver and software, and then use the software to dial up to connect to the network.
Notes
- We do not recommend that you use 3G wireless Internet access because it is expensive currently. If you must use it, we recommend that you use a discount package.
- Now there are WiFi cities in many cities in China. If your city has such free WiFi hotspots, you can search for signals and use these free WiFi hotspots to access the Internet, generally, you can browse the webpage smoothly.
