It is only a signal sending and receiving device, and the connection to the Internet can only be realized when the exit to the Internet is found, and all wireless network cards can only be limited to the range of the wireless LAN that has been deployed. A wireless network card is a network card that is not connected through wired connections and uses wireless signals to connect.

The wireless network of mainstream applications is divided into two ways: GPRS, mobile phone wireless network access and wireless LAN.

Hello dear! The reasons for this phenomenon are as follows: 1

Responsibilities of the operator (transmission and switching network failures): the operator must ensure that the signal quality (bandwidth, bit error rate, signal-to-noise ratio, transmission rate, signal level, input and output impedance, signal stability, and stability of input and output impedance meet national standards) to the user); Specific**: Telecom 10000 Netcom 10060 Tietong 10050 II:

** The software is unstable; 3: ** The quality level of operation and maintenance is low; Failure to troubleshoot in a timely manner; For example, if the other is very good, and a certain one is particularly bad, this is the problem of the company itself, and it has nothing to do with the operator or the user.

The wireless network card needs to be used for Internet access through the wireless connection network under the wireless coverage of the wireless LAN. In other words, a wireless network card is a device that enables a computer to use wireless to access the Internet.
