There’s always something to spoil your free fun. The one fun thing that’s available for free – a public Wi-Fi network at a coffee shop or a train station – that you’ve always enjoyed making use of, the spoilsports have to always warn you about it.

Everyone has to tell you that these things aren’t safe and that there can be all kinds of malware that the jump from one computer to the next over such a network.

Not only do people just idly browse the Internet when on a public Wi-Fi network, they even do stuff that’s supposed to be private or personal – their banking, buying stuff over the Internet, their taxes.

Now no one’s going to ever listen to advice on how they are never to do this. If something seems harmless on the surface, people are going to do it no matter what.

So here are a few tips on how best to secure yourself if you do find yourself unable to resist the temptation of the public Wi-Fi network.

There are nearly 100,000 free Wi-Fi hotspots around the country. When you do anything on such a network, your laptop sends out a wireless signal with all of that data right there.

Both the router that enables the hotspot and any spying person can pick up that signal. Coffee shops could provide an encrypted signal; but that would mean having to help customers connect; and no coffee shop wants to be burdened with tech support. So basically, hotspots offer no security whatsoever. Read the rest of this entry →

The range of operation is decided mainly by the access point that you have. The power of your access points would decide on how long or how far off you can carry your laptop or your client desk top from the access point.

The range of operation is normally not set in a fixed way, but is realized when you move away from the access point.

Where there is not enough signal strength for the system to log on and work on the network, it can disconnect from the network. This will be the limitation caused by the location of the wireless network. As a user, you should be aware of these limitations and the maximum you range you can cover at your home.

You might have to reconnect if you go out and come back in. This could spoil any server based work if it is running when you are moving out of the network space or hot spot. Read the rest of this entry →

Components that make up your wireless system are simply the two units: one, the wireless router or the access point and two, the wireless card or the connectivity over a WiFi card.

In the case of the access point, you can also connect to an Ethernet network or to a broadband internet line. That is the additional facility that you might have on your wireless router.

On your wireless card, if you have configured with a server allocated IP address, it is easy for your laptop to be placed anywhere and still get connected to any of the servers there, provided they are also configured in the same way.

Dynamic allocation is therefore, the best method for connection where you might move in and out of multiple networks or there are multiple numbers of people who might log in and out of the network. Under all these circumstances you will find that the laptop is better configured and equipped to work at ease with this wireless modem. Read the rest of this entry →

A wireless system requires you to have a wireless card that does the job of receiving and transmitting data. This is either on your computer or laptop.

Most laptops, as I said earlier, come with the card installed on it. All that you have to do: go to your operating system and enable the card. You can start using it immediately.

Well, this might not be the case with all machines or laptops. Please note that there are also laptops that fitted with Bluetooth and not with WiFi. In these laptops and machines, you need to install the wireless card to get it connected to the access point. Read the rest of this entry →

Ok, so who are the people that make these gadgets? All that you would require are these two components primarily, all the rest are optional.  However, we will take a closer look at these two components and a bird’s eye view of the others.

One of the largest wireless router or access point makers is NetGear. There are also others like D-link, Buffalo, Linksys and Kyocera.

There are also others who make the same products; the capacities/sizes are relatively smaller. Most of these manufacturers make both the access points as well as the cards for your computers.

Again the cards come as plug-in options, adaptable with your computer; they can also be fitted into your laptop’s USB port. Most of the laptops these days come with an inbuilt WiFi adapter. Read the rest of this entry →

If you want to do wireless networking, you need a device that will link the computer to the server over a wireless transmission system.

This is a device we call the access point. You will connect to this access point from your computer. Normally, this is the nearest access point or the strongest access point.

The word ‘strongest’ refers to the signal strength at that point! Make sure you have a wireless card on your computer or laptop. Read the rest of this entry →

The most common networking was and continues to be the wired network; however the popularity of this is waning.  On the other hand, the popularity of wireless networking is on the rise simply because of the comfort it provides its users.

There is not much difference in the way a wireless and a wired network work. It is in the way the signals are carried from one point to the other that they differ.

In case of a wired network the signal is transmitted over the wire as an RF signal. In the case of a wireless network, the signal is transferred to the destination as an RF signal transmitted over the air.

As the ease of wireless networking increases, its popularity will keep growing. Read the rest of this entry →
