Signal Wifi Rendah ?

Jika anda medapat signal wifi terlalu rendah,anda boleh cuba beralih dari kedudukan sekarang atau memusing kedududukan Laptop anda kerah Antena wifi berada.

Jika masih lagi menerima signal yang rendah anda boleh mencuba dengan menggunakan alat bantuan Wifi Reciver yang berada di pasaran berkemungkinan radio reciver pada laptop anda lemah atau anda berada jauh dari pemancar.

contoh alat penerima yang berada di pasaran





Kebanyakan alat penerima boleh menerima signal dengan lebih baik berbanding dengan menggunakan antena yang sedia ada pada Laptop anda.

Alat penerima ini juga boleh diguna pakai pada Komputer di rumah untuk menerima gelombang wifi dari Ases Point yang berdekatan

Contoh alat penerima yang di pasang




Boleh mencuba untuk mendapatkan hasil yang baik.

How a Wi-Fi Network Works

In order to understand wireless networking at its simplest level, imagine about a pair of $5 walkie-talkies that you might purchase at mall. The walkie-talkies are small radios that can transmit and receive radio signals. When somebody talks into a walkie-talkie, his voice is picked up by a microphone, encoded onto a radio frequency and transmitted with the antenna.

Another walkie-talkie can receive the transmission with its antenna, decode the voice from the radio signal and drive a speaker. Simple walkie-talkies like this transmit at signal strength of about 0.25 watts, and they can transmit about 500 to 1,000 feet. In order to consider how these walkie-talkies can be used to communicate between the two computers, we have to require that each computer is equipped with a walkie-talkie. Then, we would give each computer a way to set whether it wants to transmit or receive. After that, we would give the computer a way to turn its binary 1s and 0s into two different beeps that the walkie-talkie could transmit and receive and convert back and forth between beeps and 1s/0s. This would actually work.

However, there are some problems with that. The problem would be that the data rate would be very slow. A $5 walkie-talkie is designed to handle the human voice. So, it would not be able to send very much data this way. Another problem is the walkie-talkies could not be used to connect to the internet. The radios used in Wi-Fi are not so different from the radios used in the walkie-talkies. They have the ability to transmit and receive. They also have the ability to convert 1s and 0s into radio waves and then back into 1s and 0s. However, there are major differences between them. Wi-Fi radios that work with the 802.11b and 802.11g standards transmit at 2.4 GHz, while those that comply with the 802.11a standard transmit at 5 GHz. Normal walkie-talkies normally operate at 49 MHz The higher frequency allows higher data rates. Wi-Fi radios use much more efficient coding techniques (process of converting 0’s and 1’s into efficient radio signals) that also contribute to the much higher data rates. The radios used for Wi-Fi also have the ability to change frequencies. For example, 802.11b cards can transmit directly on any of three bands, or they can split the available radio bandwidth into dozens of channels and frequency hop rapidly between them. The advantage of frequency hopping is that it is much more immune to interference and can allow dozens of Wi-Fi cards to talk simultaneously without interfering with each other.

Wi-Fi hotspot
A Hotspot is a geographic area that has a readily accessible wireless network. Hotspots are equipped with a Broadband Internet connection, and one or more Access Points that allow users to access the Internet wirelessly. Besides, hotspots can be setup in any public or private location that can support an Internet connection. Basically, any location which caters to business users and where people with laptops are likely to make frequent visits is an ideal choice to install Wi-Fi. The good examples of this location are airports, hotels, resorts, restaurants, coffee shops, bookstores, shopping malls and other relevant places.
A Wi-Fi hotspot is created by installing an access point to an internet connection. An access point acts as a base station. When Wi-Fi enabled device encounters a hotspot the device can then connect to that network wirelessly. A single access point can support up to 30 users and can function within a range of 100 –150 feet indoors and up to 300 feet outdoors. Many access points can be connected to each other via Ethernet cables to create a single large network.
Connecting to hotspot
There are actually two steps to making a connection. The first step is to have your notebook "talk" to the hotspot, which means that the hardware and hotspot must recognize each other. This should happen automatically as long as your wireless hardware is turned on and new. On the newest machines, an 802.11 card will automatically connect with an 802.11 hotspot and a network connection will be established. As soon as you turn on your machine, it will connect and you will be able to browse the Web, send email and others using Wi-Fi.
On older machines you often have to go through a simple 3-step process to connect to a hotspot. The first step is to access the software for the 802.11 card – normally there is an icon for the card down in the system tray at the bottom right of the screen. Secondly, you have to click the "Search button" in the software. The card will search for all of the available hotspots in the area and show you a list. Finally, you need to double-click on one of the hotspots to connect to it.
On ancient 802.11 equipment (more than 2-3 years old), there is no automatic search feature. You have to find what is known as the SSID of the hotspot (usually a short word of 10 characters or less) as well as the channel number (an integer between 1 and 11) and type these two pieces of information in manually. The entire search feature (in newer equipment) is doing is grabbing these two pieces of information from the radio signals generated by the hotspot and displaying them for you.
On most notebook models, you will see some sort of signal icon on the bottom right hand corner of your screen or a lit indicator on the notebook itself, which will give you feedback for "On" and signal strength (a red screen means your radio is Off; a green screen indicates it is On). You can also see the quality of the signal by clicking on the radio icon (may vary by system). The next step is to sign up with a wireless Internet service provider and configure your notebook according to their instructions. Most of the time, this is a matter of simply launching your web browser. It will automatically go to the wireless service provider's sign-in page. It must keep in mind that different hotspot locations work with different service providers, but each hotspot location should provide easy and clear instructions on how to connect. If someone do not subscribe to a service, chances are you will need to use your credit card to pay for access every time you want to connect. Furthermore, always make sure you know what the service provider charges, as there can be a wide range of prices. After this, you will end up at the log-on page of the wireless provider (or, in some cases, the wireless location). If so, simply follow the instructions to sign up for the service, or enter your user name and password if you are already a customer. Once you successfully log on, you should see the following icon in your tool bar, indicating the connection has been made.
How to use

You must have wifi device like laptop, netbook, pda, wifi phone, or something can use the wifi device service to connect to the internet. Find the SSID (Service Set IDentifier) of our services on your equipment and connect. Then open any browser to surf the internet, login page will appear. You must have a hotspot prepaid card to log in. After you get the Username & Password from hotspot prepaid card, you can surf the Internet anywhere at any time until time runs out.
