WIRELESS LAN’S A Wireless LAN is a wireless local area network that connects two or more computers or devices without using wires. It is commonly called as WLAN.
It was developed by IEEE 802.11(Institute of electrical and electronic engineering). 802.11standards use the
Ethernet protocol and CSMA (carrier sense multiple access with collision avoidance) for path sharing.
WLAN devices allow users to move their laptops from one place to another place within their offices without the need for wires and without losing network connectivity. W
WIRELESS LAN’S:
But the WLAN connects computer to a network using an access point devices. This access point communicates with devices equipped with wireless network adaptors and it connects to a wired Ethernet LAN. This access point
Devices have a coverage area up to 300 feet (approximately 100 meters).
WIRELESS LAN COMPONENTS:
A Wireless LAN comprises two types of equipments.
1. A wireless station
2. Access point
A wireless stations are equipped with wireless networks interface card (NIC).Access points are base station for the wireless networks, they transmit and receive radio frequency to communicate with wireless devices. Wireless clients can be mobile device such as laptops, personal digital assistants, I phones and fixed devices such as desktops and workstation that are equipped with the wireless network interface (NIC).
Nowadays WLAN are becoming popular in more wide range of business customers.
For example:
Hospitals, Universities, Hotels, retail shops are using this wireless technology to conduct their daily business operations.
BENEFITS:
Wireless LAN’s offer five primary benefits
USER MOBILITY:
Users can access files, network resources and internet without physically connected network to the wires.
RAPID INSTALLATION:
The installation time is very less because the network connection can be made without adding wires, or pulling it through walls or ceiling, or making modification to the infrastructure cable plant.
REDUCED COSTS:
The initial investment of wireless LAN is little higher than the wired LAN, but there is no need of installation charges and the wiring charges.
SCALABILITY:
WLAN network topologies can easily be configured to meet specific application and installation needs and to scale from small peer to peer network to very large enterprise network that enable roaming over a broad area.
FLEXIBILITY:
Users can quickly install a small WLAN for temporary needs such as a conference, tradeshow or in the meetings. It is flexible so we can take WLAN in our necessary locations.
So Wireless LAN’s is best to fit your computers or devices to communicate over a network.

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….

just depress that wireless button and it will turn blue again meaning it's back on

In short because there are no cables to connect, you can use it anywhere within range, not just where the network socket is.
Wireless still isn't as secure / fast as wired networks though, for most web browsing wireless with security enabled (WPA) is fine but for mass file transfers, 100 or 1000 mbit Ethernet is way faster.

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.

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

It could be done. The trouble is either the wiring house to house. Or 2 the range of the wireless N devices. If you had a router with 4 port switch you could plug the 4 routers into it. Each getting a seperate ip address from the internet connected router. The 4 routers would then have to be setup on seperate subnets. Each house getting a seperate SSID.

Just swap your "Linky's wired router"and your "Linky's wireless router". The setup should be very similar. Have your modem connected to the back of the wireless router, and your wired PCs connected to the front connections. You wireless laptops should detect the new wireless network.
This is all assuming you have no setup involved. You will probably have to install some software on the laptops and then configure the wireless router security (so not just anybody can get in), but your router's instructions should cover those steps.

Hi,
A good idea would be to try changing your router's "Wireless Channel" to Channel 4 (or other) as most other channels are affected by interference from house hold items such as microwaves, wireless phones etc.
If this does not fix the issue try other Channels
I hope this helps.
Edit: Glad i could help =)

First, contact your cable provider and ask them what wireless router would be compatible with their service, this first step is very important. Once you have your sevice compatible wireless router I am 100% they will have no issue helping you configure it with your account.
CABLE AND DSL WIRELESS ROUTERS ARE NOT THE SAME.

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.

Chris i need help, my local area connection is saying its unplugged my i have a cable in the port how can i fix this?

@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.
