Understanding Wifi Networks

On the road you can often find locations with Wi-Fi broadcast devices that your laptop computer can talk to. Such a broadcast device is also known as an access point, hotspot or an AP.

With your access point located, you're ready to sit right down, establish a wireless connection, and start reading your email and surfing the Web, right? Not so fast, partner.

It's really important to understand that being able to "talk" with a wireless access point just means that you can "talk" with a wireless access point. It doesn't mean that you can connect to the Internet unless the wireless access point is itself connected to the Internet.

So if Starbucks or whoever wants to provide you with the chance to surf on their turf while you sip that latte, Starbucks needs to provide an Internet connection. Generally, this connection is wired, and uses a cable or DSL (digital subscriber line) telephone line for high speeds.

A high-speed wire brings the Internet to the location, and a Wi-Fi access point broadcasts the wireless Internet connectivity to wireless devices (in techno geek-speak, the wireless devices are generically referred to as clients).

Between the Internet connection and the Wi-Fi access point, there also needs to be some hardware designed to connect with the Internet and share the connectivity. There are a whole lot of different ways this can be done, depending on many factors. For example, is a wired network also involved?

You need to understand that connecting to the Internet via Wi-Fi involves four things:

  • Your Wi-Fi device (the client)

  • A Wi-Fi broadcast unit (the access point)

  • Network connectivity hardware (such as a router and modem)

  • The actual Internet connection (usually via cable or DSL)

Top Tips For Wireless Internet Security

You can now move around your house or office with your mobile computer while you stay connected to your wireless network. It is simple and easy to setup. Unfortunately, as they airwaves are used for communications between two devices, the communications can easily be intercepted, and vulnerable to attack, which makes it less safe than wired connection. So find below few tips to enhance your wireless connections:

 

  • The use of an encryption key (WEP) is the basic to secure your wireless connectivity.

  • You can then use a stronger encryption also known as Wi-Fi Protected Access (WPA)

  • Most routers have a default administrative password that you need to change as soon as possible.

  • You can also turn off the broadcast name (this is the name associated to your access point to make it easy for the wireless users to connect to it). It's also known as SSID broadcasting.

  • When you are not using the wireless access point (WAP) then turn it off.

  • Changing the default SSID can enhance your security.

  • Each network device has got a unique ID which is called “MAC address”. So you can use the wireless access point to choose who you want to allow onto your wireless network.

  • You can create a secure zone to isolate the wireless network from the rest of the LAN (local area network).

  • You always have the option of controlling the wireless signal strength; you might not want it too strong when not needed.

  • And finally you can transmit on a different frequency. As most WAP have got a default frequency on which they communicate with the wireless devices.
