Occasionally, problems may occur with your wireless router. When they do you are likely to lose all or partial access to the internet, and so you will want to resolve them as quickly as possible.
The first thing to do is work out whether you have completely lost access, or whether it is just running very slowly. If it is down completely then it is likely that your internet service provider is having problems and you may not be able to overcome it.
When your net goes down completely your modem will normally display a warning signal in the form of a flashing light, or the absence of the light that normally indicates that the internet is working.
Your router may also display a similar warning-the modem input light may change to red, may flash or may stop showing.
When this happens you can try and reboot both the router and the modem. However if this does not work you are likely to have to wait till your service provider corrects the problem. 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 →

For every one of the systems that we discussed earlier there are devices that would enable communication. In case of WiFi equipments too, you will find a number of WiFi equipments that meet your needs.
You need to have an access point which will tie to a static server over an Ethernet network as shown in figure 1.3. Access points are wireless nodes that are configured to receive and transmit wireless RF signals on a network.
It also serves to connect the computers across a network. They also bridge the wired Ethernet network with the wireless systems. 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 →
