Simplified Tutorial: how to install a 3G wireless network adapter

3G wireless network adapter can be a wireless network connected to the Internet through mobile communications. This convenient Internet access method is favored by many young people. But how do I install a 3G wireless network card? Let's take a look at this article.

First, when installing a 3G wireless network adapter, check whether other wireless network adapters have been installed before. If yes, uninstall the NIC program and software. Otherwise, the installation may fail or cannot be used properly!

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 about installing a 3G wireless network adapter:

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 3G wireless network adapter is installed, 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.
