MAIN is the main antenna interface, and aux is the auxiliary antenna interface; most Intel wireless network card motherboards only have numbers 1, 2, and 3. The main number identified is 1 (connected to the gray line), and the aux number is 2 (Connect to the black line), if there are 3, usually connect to the white line.
The operating environment of this tutorial: Windows 10 system, DELL G3 computer.
What is the interface of MAIN?
main and aux are the main antenna interface and auxiliary antenna interface respectively.
The wiring conditions of the two interfaces main and aux of the laptop's built-in wireless network card are as follows:
1. Main is the main antenna, usually gray, and aux is the auxiliary antenna, usually gray. It is black;
2. Most Intel wireless network card motherboards only have numbers 1, 2, and 3. The main number identified is 1 (connected to the gray line), and the aux number is 2 (connected to the black line). , if there are 3, usually connect the white line. For some M.2 interface network cards, the main number is 2 and the aux number is 1;
#3. The antenna is usually installed by the manufacturer. Please contact the manufacturer for after-sales verification.
Wireless network card is a terminal wireless network device. It is a terminal that uses wireless signals for data transmission without wired connection. Depending on the interface, wireless network cards mainly include PCMCIA wireless network cards, PCI wireless network cards, MiniPCI wireless network cards, USB wireless network cards, and CF/SD wireless network cards.
The role and function of a wireless network card are the same as those of an ordinary computer network card. It is used to connect to a local area network. It is just a device that sends and receives signals. It can only be connected to the Internet when it finds an exit to the Internet. All wireless network cards can only be limited to areas where wireless LANs have been deployed. A wireless network card is a network card that uses wireless signals to connect without a wired connection. The mainstream application of wireless networks is divided into two methods: GPRS mobile phone wireless network Internet access and wireless LAN.
The formulation of the new generation wireless LAN standard IEEE 802.11n is expected to be completed, but the huge market potential has prompted wireless LAN manufacturers to launch 11n draft products in advance. Due to the inconsistency of the standards used, there is a gap between 11n products. In response to this situation, the Wi-Fi Alliance formulated the Wi-Fi 11n (Draft 2.0) interoperability test method to ensure good interoperability between 11n draft products.
