A wireless LAN (or WLAN, for wireless local area network, sometimes referred to as LAWN, for local area wireless network) is one in which a mobile user can connect to a local area network (LAN) through a wireless (radio) connection. The IEEE 802.11 group of standards specify the technologies for wireless LANs. 802.11 standards use the Ethernet protocol and CSMA/CA for path sharing and include an encryption method, the Wired Equivalent Privacy algorithm. A wireless local area network (WLAN) is a local area network (LAN) that doesn’t rely on wired Ethernet connections. Originally WLAN hardware was so expensive that it was only used as an alternative to cabled LAN in places where cabling was difficult or impossible.A WLAN can be either an extension to a current wired network or an alternative to it.
Use of a WLAN adds flexibility to networking. A WLAN allows users to move around while keeping their computers connected. The private home or small business WLAN Commonly, a home or business WLAN employs one or two access points to USB WIRELESS LAN Adapter RT3070 broadcast a signal around a 100- to 200-foot radius. You can find equipment for installing a home WLAN in retail stores like Office Max, Radio Shack, Target, and Walmart, among others. Using technology from the Symbionics Networks, Ltd., a wireless LAN adapter can be made to fit on a Personal Computer Memory Card Industry Association (PCMCIA) card for a laptop or notebook computer. For the home user, wireless has become popular due to ease of installation, and location freedom with the gaining popularity of laptops. Public businesses such as coffee shops or malls have begun to offer wireless access to their customers;USB WIRELESS LAN Adapter some are even provided as a free service. Large wireless network projects are being put up in many major cities: New York City, for instance, has begun a pilot program to cover all five boroughs of the city with wireless Internet access. The third generation of wireless modem then aimed at compatibility with the existing LANs with data rates on the order of Mbit/s.
Several companies developed the third generation products with data rates above 1 Mbit/s and a couple of products had already been announced by the time of the first IEEE Workshop on Wireless LANs. WPA implements higher security and addresses the flaws in WEP, but is intended to be only an intermediate measure until further 802.11i security measures are developed. Although a WAN by definition is the exact opposite of a LAN, wireless WANs (WWANs) deserve brief mention here, http://www.papatek.com/Network-Device/ USB 802.11N 150/300M WIRELESS LAN Adapter especially because the distinction is becoming less and less obvious to end users.

One way to effectively kick people off is to discover who they are. Devices can be used to locate the source (home, apartment, etc) of a signal accessing your connection. At the same time, programs used by hackers can hack their connections as well, allowing you to monitor until info is found to identify your suspect. If either method is successful, hire a lawyer and sue the scum for all he has – including his computer.

A built-in wireless LAN and a built-in wireless card are the same thing and the terminology can be used interchangeably. A wireless card allows you to connect to a wireless network.
An Ethernet LAN is just a network to which you connect to via a Ethernet cable, also known as a network cable, also known as Cat5 or Cat6.

i use wpa2 (AES) with a 63-character long password consisting of random upper-case, lower-case, numbers and symbols. Hopefully this will be enough to secure my network….

These days a wireless lan adapter is a Wifi adapter. The makers just use the terms they like to use so they drive us consumers batty!
The Intel Pro Wireless is a good wifi adatper.
Check the specs they should say 802.11 with the following numbers.
a – 5 gig channels
b – old 11 mbs units
g – 54 mbs units (most common)
n – the newest faster wifi system
so a unit with 802.11 a/b/g/n or 802.11 a/n they have all possible wifi connection types.

Remember MAC Addresses can be spoofed. But hiding the SSID, WPA2, and MAC filtering is usually more than enough to stop the script kiddie next door

@mewrox99 I agree, i always setup WPA2 and mac filter, i run alot of wireless stuff so hiding doesnt work in my case.
Its too easy to spoof MAC’s, also WEP is easily cracked, would not suggest it either.

I am sure you can use any wireless ethernet bridge. You don't have to buy the Samsung one. It will probably be cheaper as well.
Google ethernet wireless adaptor.

Ok im getting the wifi from the router but i dont know why it wont let me get into the internet? what do i do?? Please Help

If you have a router and both the PC and the laptop are connected to it, you are connected to a LOCAL AREA NETWORK (LAN). The only difference is that the wired machine uses a wire and the wireless unit doesn't.
If you want the two machines to communicate over the "exisiting" connection, just setup your network on both machines. It requires the "workgroup" to be set and the file and printer sharing to be enabled on both machines. Once that is done, you have a full working lan!
Here are some easy to use guides.http://www.pcworld.com/article/102461/how_to_set_up_your_home_network.html
In all honesty, just run the network setup wizard which is included on XP, Vista, Win7 on each machine, give each machine a common workgroup name and a unique computer name (don't have two machines called the same name) and your done.

go up to your URL bar, put a Q between the words you and tube and then press enter or click go

If i can translate this question as this u really can understand the difference by urself …it goes like
"What is the difference between internet and LAN"
thts all now to ur question :
WIFI -s a service & WLAN – is application which uses the wifi/wimax service
u can decide tht whether u need wlan or not but u may need wifi for accessing netfrom HOTSPOT /Access point(AP)
…..jus Wireless lan is incomplete without internet …subscribe either for wifi/wimax or wired Internet ie:broadband
did i address ur question .
#15 by jpro on April 26th, 2010
is wireless lan the same thing as wifi? if so then whats so different about wifi?
#16 by truth on April 26th, 2010
Also i wanted to add that most people run WRT54g linksys router, the best thing i can say is go with DDWRT firmware, gives LOADS of features that most people will probably never use.
