A wireless router or access point's signal typically extends up to approximately 300 feet.
Many routers act as WLAN access points. They connect multiple computers (and wireless-capable printers) to a single WLAN and to the Internet.
You can extend WLANs throughout an area by placing additional wireless access points in various locations. The access points extend the wireless signal's range and strength.
Most laptops have built-in wireless networking. If yours doesn't, you'll need a wireless network adapter card, which is typically inexpensive and easy to install.
There are many ways to secure your WLAN, including:
- Data encryption, which only gives authorized users access to information over your wireless network
- User authentication, which identifies computers trying to access the network
- Secure access for visitors and guests
- Control systems, which protect the laptops and other devices that use the network.
Small businesses can experience many benefits from a WLAN. A few examples:
- You can access network resources from any location within the wireless network's coverage area.
- Wireless access to the Internet and to company resources help your staff be more productive and collaborative.
- You don't have to string cables, as you do with wired networks. Installation can be quick and cost-effective.
- You can easily expand WLANs where and as needed, because no wires are involved.
- By eliminating or reducing wiring expenses, WLANs can cost less to operate than wired networks.
Your problem could have many causes. There are a few things you can check yourself:
Make sure the cable is properly connected to your computer and the wall jack. Check the cable's condition. If the connectors at each end of the cable are not securely connected, or if one of the connectors doesn't 'snap' securely into a jack, you may have a faulty cable. Borrow a network cable to confirm this is the case.
Whether you work in a wired network office or a wireless one, one thing is common for both environments: It takes both network software and hardware (cables, routers, etc.) to transfer data from your computer to another—or from a computer thousands of miles away to yours.And in the end, to get the data you want right to YOU, it comes down to addresses.
So not surprisingly, along with an IP address (which is networks software), there's also a hardware address. Typically it is tied to a key connection device in your computer called the network interface card, or NIC. The NIC is essentially a computer circuit card that makes it possible for your computer to connect to a network. An NIC turns data into an electrical signal that can be transmitted over the network.
“IP" stands for Internet Protocol, so an IP address is an Internet Protocol address. What does that mean? An Internet Protocol is a set of rules that govern Internet activity and facilitate completion of a variety of actions on the World Wide Web. Therefore an Internet Protocol address is part of the systematically laid out interconnected grid that governs online communication by identifying both initiating devices and various Internet destinations, thereby making two-way communication possible.
An IP address consists of four numbers, each of which contains one to three digits, with a single dot (.) separating each number or set of digits. Each of the four numbers can range from 0 to 255. Here's an example of what an IP address might look like: 78.125.0.209
