How to wireless internet for desktop computers

　　Wireless internet is now very popular way of surfing the internet, without the shackles of network cable, is not the Internet more free AH ~ ~ ~ (feel It). Usually we use mobile phones, netbooks, ipads, Itouch, laptops and other wireless internet access, then the desktop is also wireless internet? The answer is yes, and then we'll talk about how to make the desktop wireless Internet. (This article refers to the wireless internet mainly refers to the network through WiFi hotspots).

Terminology interpretation

　　Wireless internet -------Baidu Encyclopedia to our explanation is: the so-called wireless internet is divided into two kinds, one is through the mobile phone to open data function to the computer through the mobile phone or wireless network card to achieve wireless internet, speed is based on the use of different technologies, terminal support speed and signal strength to jointly decide. Another type of wireless Internet access is wireless network equipment, which is based on traditional LAN, wireless AP and wireless network card to build wireless Internet access. It is generally believed that as long as the Internet terminals do not connect wired lines, are called wireless Internet.

　　The wireless internet we're talking about here is the one behind it.

Steps/Methods

Our average desktop does not have wireless reception, so we need to install a wireless reception device for the machine. Our first is the wireless network card. Wireless network card can be divided into built-in and external two types, built-in the following figure:(to avoid the suspicion of advertising, I will be the brand of the network card to do a fuzzy processing)
This network card requires you to open the host box of the machine, then install the NIC into the free PCI slot, then install the host box, then the driver of the network adapter. This requires the user to have a certain hands-on ability, because such a network card with an external receiving antenna, so the reception ability of the signal and the stability of the signal is good. But for those who have not insured the brand machine, some brand-name machine host box is affixed with a laser-fragile label, if opened the chassis, then there is no warranty, so it is recommended that these users use the following external USB network network card.

The external wireless card is now basically USB interface. As the following figure, although the shape is different, but the hundred change from its case.

This is like a U disk, but larger than a U disk, is a built-in antenna. Now the USB wireless card is doing more and more good-looking.

This is with the receiving antenna, can improve the reception ability of the signal. This is also with the receiving antenna, the style is still very good-looking.

USB type of wireless network card, we just plug the network card directly on the USB interface, and then the system will find new hardware, and then we install the driver can be.

After USB is plugged into the USB port of the host, the system will be prompted to find new hardware, pop-up driver installation Interface (PCI interface of the built-in wireless card is also the case, the installation of the boot, enter the system will be prompted to find new hardware) generally do not recommend automatic installation, we select "from the list or specified location (Advanced)" This option, And then the next step if the driver is on the disc, you can use the "Search removable media" item, if it has been copied on the local hard drive, then select the following "Include this location in the search", and then through the "Browse" button to select the path, the next step of the system will automatically install the driver installation completed, click Finish.

Then double-click the Wireless network icon in the lower-right corner of the system to eject the wireless network connection. (note that if the service in your system: Wireless Zero Configuration is disabled or closed, then the wireless network connection is not available, you need to go to the Control Panel--------management tools-------Services Find this service inside, then turn on him and set it to start automatically. Then, in the list of selected wireless networks, there will be some wireless signals (if they are nearby) that are typically sent through a wireless router that is connected to a broadband connection. Wireless routers are also an important part of wireless networks.

　　No line by the setting here I will not detail, you just pick up the power, plug the network cable, log on to the Web Page Settings window, and then set the broadband user name and password according to the Setup wizard.
Double-click the target you want to connect to, and then automatically try to connect. The first connection will have such a warning. We choose to still connect, after connecting the basic will be able to surf the internet ~~hoho.

　　If you find that you cannot connect to the network, check the IP settings and NDS settings: the Control Panel-------Network connection------The local Area Connection-----(right) Property--------Internet Protocol (TCP/IP)------- Property and then eject the settings interface, you can set up your own IP (generally set to Automatic), DNS (this recommendation to fill in your broadband operator's DNS server address, so easy to browse smoothly)

Finally, a brief introduction to the use of 3G network for wireless internet access.

3G Internet is following the GSM, GPRS, edge of the new technology, one of the three major domestic operators China Mobile is the independent property rights of TD-SCDMA, speed up to 2.8M; China Telecom uses CDMA 2000 technology, now erected EVDO REV. A network speed of up to 3.1M. While China Unicom adopts the international mainstream WCDMA technology, the theoretical speed can reach 7.2M. The speed is quite good, that is, the charges are more expensive.

3G USB Wireless Card profile and the above USB card shape and similarity, just inside will plug in a 3G mobile phone card. Then the installation is also very convenient, plug in the computer's USB interface, the accompanying CD-ROM in the CD-ROM drive and software installed, and then use this software dial-up can connect to the network.

Attention matters

　　As a result of the 3G wireless internet is more expensive, do not recommend that you use, if you must use, recommend the use of preferential packages.

　　Now many cities in the country in the establishment of WiFi city, if your city has such a free WiFi hotspot, you can search the signal you can use these free WiFi hotspot for the internet, generally browsing the web or relatively smooth.
