With PCs running Windows, it's important to keep their software up to date with the latest patches. Microsoft's Windows Update tool helps you find the newest versions of software and install them via the Internet. Unfortunately, your PC might suddenly start failing to connect to the Windows Update servers, even if your home network and Internet connection are working fine otherwise. Why? Follow the discussion on our message board to watch our members walk through the typical troubleshooting steps. Sunday, December 21, 2008
The WZR2-G300N is Buffalo Technology's mainstream Wireless-N broadband router rated at 300 Mbps. Many agree this product has excellent performance. Unfortunately, an ongoing U.S. Patent dispute over use of certain Wi-Fi technology led to a court order in mid-2007 prohibiting Buffalo from selling these routers in North America. With a new development in the legal proceedings that occurred this month, look for Buffalo to resume sales of the WZR2-G300N very soon.→ More - Buffalo WZR2-G300N Wireless-N Nfiniti Router, from Buffalo Technology (currently featuring a legal status update)

Question: What is (Wireless / Computer) Networking?
Answer: In the world of computers, networking is the practice of linking two or more computing devices together for the purpose of sharing data. Networks are built with a mix of computer hardware and computer software.
Area Networks
Networks can be categorized in several different ways. One approach defines the type of network according to the geographic area it spans. Local area networks (LANs), for example, typically reach across a single home, whereas wide area networks (WANs), reach across cities, states, or even across the world. The Internet is the world's largest public WAN.
Network Design
Computer networks also differ in their design. The two types of high-level network design are called client-server and peer-to-peer. Client-server networks feature centralized server computers that store email, Web pages, files and or applications. On a peer-to-peer network, conversely, all computers tend to support the same functions. Client-server networks are much more common in business and peer-to-peer networks much more common in homes.
A network topology represents its layout or structure from the point of view of data flow. In so-called bus networks, for example, all of the computers share and communicate across one common conduit, whereas in a star network, all data flows through one centralized device. Common types of network topologies include bus, star, ring and mesh.
Network Protocols
In networking, the communication language used by computer devices is called the protocol. Yet another way to classify computer networks is by the set of protocols they support. Networks often implement multiple protocols to support specific applications. Popular protocols include TCP/IP, the most common protocol found on the Internet and in home networks.
Wired vs Wireless Networking
Many of the same network protocols, like TCP/IP, work in both wired and wireless networks. Networks with Ethernet cables predominated in businesses, schools, and homes for several decades. Recently, however, wireless networking alternatives have emerged as the premier technology for building new computer networks.
