3G wireless network adapter User Guide

3G network cards are currently a hot spot in the market. High-speed wireless Internet access has aroused a lot of interest. With the maturity of 3G technology, wireless Internet access will become the way to access the Internet in the future. In view of the fact that many people do not know much about the 3G network card, there are often problems that may not be correctly used at the beginning of the purchase. The following describes some common problems and precautions for using the 3G network card.

First, when installing a new 3G Nic, check whether other wireless NICs have been installed before. If yes, uninstall the NIC program and software. Otherwise, conflicts may occur, causing installation failure or unavailability! During the first installation, the NIC maps a CDROM optical drive. The operating system installs the driver for the CDROM optical drive and then reads the image file from the CDROM. This process may take several minutes, especially in vista.

FAQs:

1. After the ENI is inserted, it will not be installed automatically:

Some anti-virus software disables the CD auto-boot function. You need to disable the corresponding anti-virus software, such as McAfee and 360 security guard. Disable the software and re-insert it to the terminal for installation.

2. After the NIC program is uninstalled, the NIC will be re-inserted. No automatic installation will occur and no removable disk will appear:

When the program is uninstalled, only the client Internet Access Program is uninstalled, and the driver of the data card is not uninstalled at the same time. When the data card is inserted, the computer considers that the driver has been installed, the installation will not be prompted. There are two solutions:

A) Go to the internet star website or the local provincial Telecom online business office to download the latest "wireless broadband" client program. After installation, you can use it.

B) pause the "Udisk Monitor" service and start the service after installation:

Right-click my computer on the desktop and choose manage or service.

Go to the Service Page, find a service named "Udisk Monitor", and stop the service.

Re-insert the terminal and install it using the built-in driver.

After the installation is complete, restart the "Udisk Monitor" service according to the preceding steps. if the service is not restarted, the following message is displayed: "The client and driver are prompted to be installed every time the network card is inserted.

Considerations for surfing the internet

The Internet speed of the wireless network adapter depends heavily on the network. Unlike the stable speed of the wired broadband Internet access, moving the network adapter may cause a rapid decline in the Internet speed, different network conditions may vary greatly in the Internet speed. When the signal is poor, the download speed may only be about 10 kb/s (80 kb/s). When the signal is good, the average download speed of a 3G Nic can reach 2.4 kb/s (Mb/s) or higher.

The speed of the NIC depends on the following parameters:

Signal strength: currently, the 3G network is not fully covered. In some regions, only 2G signals cannot connect to 3G networks, and the speed will be low. In some regions, the edge of 3G signal coverage is, in this area, switching between 3G connections and 2g connections may affect the speed of accessing the Internet. The weaker the signal, the lower the speed of accessing the Internet.

Signal Quality (signal-to-noise ratio, C/I, Ec/Io): interference may occur in the overlapping areas covered by multiple base stations. The signal quality is relatively poor, the worse the signal quality, the slower the Internet access rate.

For common users, you can only view the number of signal cells on the software interface, and there is no relevant tool to view the signal quality.

TIPS: use of DU-Meter speed measuring software

We recommend that you install similar rate viewing software such as DU-Meter and try to use the extended line provided by the terminal when using it.

If you find that the download speed is slow or the video is not smooth, open the client interface, and enable the speed measuring software to adjust the location of the data card or computer, at the same time, observe the number of client Signal display cells and the data traffic displayed on the software. When you find that the data card has the largest data traffic at a certain position, please use the data card temporarily.

We recommend that you use the following network coverage information:

When surfing the Internet, try not to be in a closed building. The signal attenuation in a closed building is large, and the signal received by the terminal is weak. The signal strength can be improved by using the window, the Internet access rate will be improved.

If you know the approximate location of the base station, you can place the NIC (or antenna) in the direction of signal transmission, and the received signal will be enhanced.

For high-rise buildings (such as 20-storey buildings, 30-storey buildings, or even higher), there are many signals transmitted in each direction on the upper floor, with relatively strong signal interference and poor signal quality, it will affect the speed of the internet, and there will also be frequent disconnections or connection failures, which can only be solved by improving network coverage. If the operator has indoor network coverage in the high-rise building, please be close to the antenna location covered by the network. Try not to back the window. The signal at the window side will affect the usage and speed.

For intensive buildings (such as the city complex), if you are on the lower layer (such as the bottom layer), try to be close to the roadside and receive relatively strong signals, or access the Internet on the high floor (dense buildings are generally relatively low, such as the city region is generally several floors, the top floor signal is relatively strong ).

You can pause or reset the automatic online update of various software types. If the software is automatically updated online, it will occupy the bandwidth and automatically download some content that may not need to be updated without your knowledge, affects the Internet experience of other programs (for example, when you watch videos online, the bandwidth occupied by software online updates may not be smooth at this time ).
