What Is Wi-Fi

Wireless technology has become a prominent field in the area of networking. It has many uses. The most important being portability and mobility. With the help of wireless technology people now can send and receive messages, phone calls, faxes, read files, login on remote machines etc. and perform all the above mentioned duties from anywhere on land, sea, or air.

The technology of wifi has stormed the field of wireless networking. There are numerous applications of wifi. Nowadays it is very useful and critical in business world because today's business gives more emphasis on the communication of the information. Wifi also finds usage at home, workplaces, shops, any public places etc. the study of the advantages and the risks involved in the wifi system is necessary in order to exploit the full use of it.

About wireless networks.

The transfer of information from node to another with the help of electromagnetic waves is referred to as wireless communication. Signals are normally broadcast through free space and are available to anyone who has device capable of receiving them. A new technique of wireless data transmission known as wifi (wireless fidelity) has been developed. Wifi uses the radio waves to transmit the data. It uses the frequency of 2.4GHz and uses SSID for addressing purposes. SSID stands for Service Set Identifier. It uses a set of characters or numbers addresses so that the sending access point can be identified. Any access point which wants to receive the signal must have the same set of SSID as that of sender's SSID.

Advantages.

The usage of wifi system has numerous advantages. The most important advantage is the cost factor. Since there are free hotspots or access points, a free connection between two nodes cab be established in the network.
A wireless network also provides the facilities of mobility. Hence it is now possible to have a wireless connection, free of hard wired connections.It is also easy to install and configure wifi network. It is also easy and generally faster, internet connections are possible by wifi networks.

Dangers and risks.

Since wifi is a wireless connection it uses the shared wireless space. Hence it is possible that many signals of similar frequencies can interfere with each other and cause unnecessary distortions. This leads to the loss of data and the received data may get corrupted. Hence wifi does not ensure an error free connection.
Another danger involved is related to security of data. It is possible that users who are new to the wifi network may setup an insecure access point, without setting the various security configurations.
It is also possible that some miscreants may use the same default SSID everywhere to access the secured access points illegally. The best way to counter these dangers is to learn and study the configuration of the secured network and make it a rule to always use a different SSID for access point and never keep the default value.

How to Play Super Smash Brothers Brawl Online? Nintendo Wi-fi Connection Errors

On March 9th at Midnight marked the release of a Nintendo Wii game that would revolutionize the Nintendo Wifi. That game was Super Smash Brothers Brawl. North America was now able to Brawl Online. Many errors still exist because it was the first major Nintendo Wifi game release. There are simple solutions to the following errors you might encounter with either your internet connection or your Nintendo Wii.

The first error you might encountered is delayed game play. This happens most often when you are Brawling in four man matches. Other reasons why this error occurs is because of a weak wireless signal or loose cables in the back of the Wii. Another solution to remove the delay is to reset the wireless router or disconnect any computers that aren't in use.

If you are disconnected completely do not sweat because the game assigns a CPU to take your place the second you are disconnected. The next error/problem that occurs is people can't get connected to other people in Anybody Mode and are waiting in a white room with a sandbag for minutes.

If you experience this error reset the game and if there is a timer in the white room you can get connected to other people in Anybody Wifi Matches. If you do not see a timer you will be waiting in that white room until you exit or get disconnected.

In order to play matches in Friends Wifi Mode you must have your friends Nintendo Wii Brawl number. You can find friend numbers on a lot of Nintendo and Smash Brothers forums online. Nintendo is fine tuning the Wifi settings and game play programming slowly as they find bugs. So over time is will be perfected to be exactly like a standard 2:00 minute Brawl match.

Any other questions or concerns can be found at the Nintendo Wii Wifi help and support online.
