How to Connect Raspberry Pi to Wi-Fi Connection of a PC – (Part 05/38)
In this project the Raspberrypi board is booted with the Ubuntu OS and is connected to the Ethernet port of a Windows7 PC. One end of the peer-to-peer LAN cable is connected to the Ethernet port of the Raspberrypi and the other end to the Ethernet port of the PC. It is assumed that the user has Wi-Fi connectivity to the PC where the Raspberrypi board is connected. In windows the Raspberrypi connected to the Ethernet port of the PC can be provided with the internet access by creating a bridge network adaptor between the Wi-Fi adaptor and the LAN adaptor. The idea is to connect the Raspberrypi board to the Wi-Fi router rather than simply sharing the network connectivity with the board. The advantage is that the Raspberrypi board will be having its own IP and can be connected with all other computers which are connected to that particular Wi-Fi network.

Wi-Fi Protocol: Networking, Frame Formats, Security, Attributes
Wireless Fidelity, more known by its short form Wi-Fi, is a digital communications protocol, through which gadgets can communicate with each other in [[wysiwyg_imageupload::]]a unicast or a broadcasting manner without using any wires. Being a wireless protocol, Wi-Fi standard uses the ISM (Industrial, Scientific and Medical) band of frequency which are free to use and require no licensing. Launched in 2.4GHz with transmission rates of 1-2mbps, Wi-Fi now works at 5GHz frequency also with astounding data transmission rates reaching upto 54mbps at both frequencies. Wi-Fi is a marketing term applied to 802.11b IEEE standard, but it now ubiquitously used for all the standards that fall under 802.11 category of Wireless LAN. So, Wi-Fi defines 802.11 x standards where x is the respective Wi-Fi version. Popular Wi-Fi version are a, b, g and n. The term “Wi-Fi” was added only to make the standard more common and rhyming with “hifi”, it was later that “wireless fidelity” took the full form of this term.
