USB Wireless Network Card, mostly install to the computers
Wireless LANs typically include one or more computers that have a wireless adapter (including PCI wireless card; USB wireless network card; and PCMCIA wireless card) which is typically 802.11 standards, plus one or more wireless access points (APs including integrated wireless router such as Wireless NETGEAR router; Linksys wireless routers; or from D-Link wireless routers; and so on). Access points bridge or route traffic from the wireless LAN to the “wired” LAN and vice versa. Unlike “wired” LAN that commonly uses Ethernet network standards, wireless LAN communicates using airwaves with 802.11 standards.
For your home networking with a wireless router, the IP addressing scheme using APIPA is commonly used if the DHCP server is not available. APIPA (Automatic Private IP Address) scheme starts from 169.254.0.1 until 169.254.255.254. APIPA is in the private addressing scheme that is not routable to the Internet.
Wireless LAN communication is really a shared LAN because only one station effectively can transmit at one time, at least in a particular constrained geography. 802.11 signals effectively might reach another device as far as 300 feet away and with a new 802.11n technology it can reach up to 500 feet. So, you can have lots of people around the planet using the airwaves for 802.11 at any one point in time, but only one device can send at a time when within range of the wireless signals.
USB wireless network card is very handy and it is very practical to use on the computers with USB ports available. Today, the computers are equipped with the USB ports you can attach to USB devices including USB wireless network card if Wi-Fi is not available yet. Some types of previous laptops which do not have Wi-Fi integrated on the boards, but some types have USB ports available – can utilize the USB wireless network card to participate in the wireless network.
The following is a list of Wireless USB Network Adapter you can consider to upgrade your computers wireless adapters.
