A wireless card can see and detect a signal to an access point, but not the IP address assigned by that access point. Have you ever had a problem like that? The failure of DHCP (Dynamic Host Control Protocol) after wireless negotiation is a common

The so-called Bluetooth technology, in fact, is a short-range radio technology, the use of "Bluetooth technology" can effectively simplify the handheld computer, notebook and mobile phone handsets, such as mobile communication terminals, and can

802.11a High-speed WLAN protocol, using 5G Hz band. Maximum rate of 54Mbps, the actual use rate is about 22-26mbps Incompatible with 802.11B, is its biggest drawback. Maybe it will be eliminated by 802.11g. 802.11b Currently the most popular

Practicality-will be implemented after the communication wiring system, not only now but also in the future can adapt to the continuous development of technology, and realize data communication, voice communication, image communication transmission.

With the rapid growth of Internet data communication, the role of the datacenter or the computer room is more and more important, the room wiring as one of the key links is the administrator need to expend a lot of effort, but some of the computer

In order to enjoy the network more smoothly, wiring should pay attention to the following matters: 1. Hardware To be compatible with network device selection, try to make all network devices adopt A company's products, which minimizes the problem
