With the increased WiFi technology progresses comes and increased wifi coverage in all the countries of the world. There are so many wireless devices that can be connected with each other that this technology is practically offering us a whole new networking perspective, that includes absolute mobility of connection. You could be practically walking the street holding a small laptop and still get constant internet access, with the help of various hot spots that are aiming to offer total coverage, especially in big metropolis.

But if you want to find for example a bench to sit on in a city park and then turn on your laptop and verify the mail you will first need to know if there are any available wireless networks in the area that allow client access freely. This can be done by finding some coverage areas from home, before leaving or by keeping the laptop or mobile device turned on all the time and scanning. Still, neither of the possibilities sounds promising. This is where the Wifi finders or Wifi detectors come in handy.

The wifi finders are small devices that work independently are their only purpose is to find and identify wireless network in the vicinity. They are used to detect wireless networks from the 802.11 protocols, and the detection is done instantly without needing to turn on the computer or the laptop. These devices usually present some type of light signals made of small led lights, that indicate the signals strength in the area. In open spaces, the wifi finders will detect wireless networks that operate no more than 60 meters away, which is a perfect opportunity of detecting networks you will actually be able to connect to if you turned on the laptop.

Using a wifi finder is as simple as it gets. All you need to do is press a button to activate it, and from here on the devices does its job. In case you are worried about other wireless signals that might be confounded with a wireless networks, know that the detectors do not present a signal when they encounter radio frequencies or frequencies that are used by mobile phone or cordless phones and microwave ovens.

A wifi finder is usually something as small as a lighter, that can be worn as a trendy keychain accessory. Because they need portability and because they work without a computer connection, these devices use batteries to function. For a person that like to spent a lot of time relaxing outside but still remains dependent to a laptop that need internet access for various reasons (work, emails, chat), a small device that can detect wireless networks in the near area is an absolute must have.

Because the wireless technology has evolved so fast there are many notions, protocols, definitions and terms that appear each day and most of them have meaning that are not deductive and are not understood correctly by the general public.

Open system is referring to a type of security that is include in wireless routers. It means that the client is identifying himself in the wireless network using his hardware address of the network card. For the infrastructure mode, the access point can have a list of hardware addresses configured, so that he knows what addresses to allow to connect. For the ad-hoc mode any hardware address is accepted in the wireless network.

Shared Key - means that an access point will verify of you know the secret network key when you want to connect to the network. The key has to be made public to all the clients of the access point and to the access point itself.

IEEE 802.1x - This wireless standard has been created for the wired Ethernet networks and them was adapted for utilizing it on wireless network using the extensible autentification protocol and other specific methods of connecting to the network.

Preshared Key - this is a method that is used for small and home networks in the infrastructure mode for encryptions like WPA and WPA2. The keys are configured in the access point and then in each client.

The connection 802.11b is like a half-duplex, because it can only send or receive data at a certain moment in time. This is the reason why the speed of traffic is usually half the connection speed. For a good quality signal and when WEP is not active, the speed is somewhere around 3.5-4.5Mbps and with WEP activated around 2.5-3.5 Mbps. This speed decreases if the signal decreases.

The wireless connection assures networks on limited distances, being influences by interferences with equipments that use the 2.4 GHz frequency (like cordless phones, microwaves). Perturbing the wireless signal will lead to errors, and some packets might need retransmitting, and the transfer speed will decrease.

A new wireless standard that is not accepted yet is called 802.11n, but it still is draft stage. This is a dual band standard and it can use both 2.4 GHz and 5 GHz frequencies, with a speed of maximum 248Mbps. This is the new generation of wireless networks at high speeds that can run on the network applications with a big broadband like video streaming and multimedia games. They also have a bigger range. This standard is based on the technology of MIMO, which means multiple inputs, multiple outputs.

Whenever you buy a new wireless router, remember that it is not secured. It comes from the production line with some general configuration settings, and everyone knows them. You have to follow a few steps to increase its security.

To connect to the router you have to access the following address: http://192.168.1.1 or http://192.168.2.1. Here you can carry on with the following methods of increasing security.

First of all change the password for the default Admin user. Initially, many routers have no password for the admin user, or they come with a pre-defined password. This pre-defined password can be found out very easy with a google search, or directly from the website of the producer from the service manual. This password has to be changed as soon as possible, and the password that will replace it must be as complex as possible.

Then, you should activate network encryption. This is initially deactivated on the majority of routers. You will have to choose between WEP, WPA and WPA2. The newest encrypting method named WPA2 should be the one chosen, if it is available on your router. This encryption must be configured both on the router and on the computer.

The next step involves changing the name of the SSID network. This SSID number will initially be the routers model number, and it is again something that can be guessed or found out. Use something random to name the network.

All router models send out signals to allow the PCs from near by that there is a wireless network available. That means anyone nearby will see the wireless network in your home or office. You are not benefiting from this feature because you already know the wireless network is there, since it is yours. If you deactivate this service the router will become invisible and only those that know the SSID will be able to connect.

The routers firmware must be up to date. There are lots of chances after you buy that it has a firmware older than the last available version. It is recommended to download and install the newest version from the manufacturers website. Also, you should constantly upgrade it throughout the use period. Each new version of firmware brings an added security and solves most of the common problems.

Another thing you can do is to activate the MAC control. Each router has this option and each pc has a MAC address, which is the hardware address. After activating this service, only some computers will be able to connect to the network, and each MAC will get added manually only by the admin.

After all the configuring and actualizing that is needed for a good functioning of the network, a backup is recommended. Each router must have an option that can backup settings. There might be situations when you might need to click the reset to factory setting button, and this backup will help you bring the router to the desired state in no time.

We will take a look at some of the advantages of the Bluetooth networks, which can provide the same kind of wireless connection as a wireless card does.

1. Bluetooth is a global standard, a universal technology and it will not fall out of fashion or disappear too soon. The money invested in equipments will not get wasted because we are still at the beginning of its development and we will be seeing more and more devices that will use this technology.

2. You can create a mini-network that is only yours, and the support is for 7 devices that use Bluetooth and are simultaneously connected, at a maximum distance of 30 meters. This is in most cases more than enough in case of a normal home.

3. This is a technology that can be easily enhanced. Researchers are already working on better versions, and safer versions. So, this is a future technology.

4. Bluetooth transformed hands free in hands FREE, having the greatest success in mobile technology. Driving, riding a bike and anything else you might think of is a lot easier when you are on the phone.

5. It has low energy consumption. Bluetooth devices do not require a lot of energy to work, because the technology has been optimized for a low consumption, perfect for mobile devices.

6. It has a standard protocol, all devices using Bluetooth are compatible and in the network anyone can get connected. I have never seen a device that returns an error.

7. The connection is automatic, easy, without requiring you to do anything. If 2 devices reach a 30 meters radius they will automatically connect. All you have to do is specify that your phone is available on the Bluetooth network.

8. The Bluetooth technology is very cheap. It is easy to include and it is the preferred technology of the media companies. Because it is produced cheaply, it reaches the user at cheap prices.

9. Bluetooth is also wireless. Perhaps this is one of the best advantages, the fact that no wires are required. Wireless devices make out lives easier.

There are many uses for Bluetooth as I’m sure you are aware. You can use it in a cell phone to connect to a Car Kit or headset and use while you are driving. You can also purchase a bluetooth usb key for use in a printer which can allow you been up to wirelessly print to this without the need of cables. The technology is of course limited as it is set already like distance but if you are in a small confined area this is a cheap and useful solution.

Various methods of measuring based on wireless technologies have been used for a long time in industry, in applications where communication over long distances is a must and where the costs for installing wires is much higher than the one of transmitting data over radio frequencies. Drill stems, gas infrastructures, pumping stations, agriculture projects, these are just a few of the examples where a wireless radio communication is successfully used. The thing that makes this method even more interesting today is the convergence of technologies pf powerful microprocessors with reduced consumption, with the technologies of huge radio devices that also have a reduces power consumption.

Minimizing these types of components makes it possible to build today a wireless network which can work on batteries for years, even if it is not under strict surveillance. The wireless sensor network is a measuring instrument that is virtually manages, which means it is handled with the help of a computer.

ZigBee represents the definition of a technical specification utilized in digital radio protocols of communications, of small power, based of the wireless IEE 802.15.4 standard for personal wireless networks. The ZigBee 1.0 version has been accepted and standardized on the 14th of December 2004.

Operating on the radio frequencies of 868 Mhz in Europe, 915 Mhz in USA and 2.4Ghz in most countries, a ZigBee radio circuit that has been produces in a very small series in the USA used to cost around 1 dollar and the price of a small controller for this network is smaller than 3 dollars. Using a technology that is much simpler and much cheaper than the one in regular wireless networks, with software dimensions that are between 2% and 10% out of the ones used for a typical Bluetooth hotspot, the ZigBee networks are designed for applications with low consumptions of power (changing batteries can be done in some cases once every two years) and that do not need high transfer rates.

A zigbee wireless network can be used in a wide amount of domains, from industrial controls, to networks with integrated sensors, Getting medical data and in anti-fire and anti-theft systems or even in automatic devices that permit the existence of intelligent buildings and homes.

In the end, it is clear that these networks have been around for a while and we are probably making used of the wireless technology in many other ways, more than we dream of. Its not only the mobile phones, laptops and entertainment devices the ones that need wireless to function.

There are so many other more vital thing that are using the wireless technology that we cant even imagine, and the fact that the wireless network used by those devices are even more evolved and a lot more secure than the ones we use in our everyday browsing makes us wonder how come we have never though about their existence.

Ever since they appeared, the wireless router enjoyed a big success. Offering the users prices that are comparable to those of broadband routers, the wireless market has risen considerably over the last few years, since it is practically the preferred solution of most Pc users.

What can a wireless network and a wireless router offer? The answer can be reduced to a single word: mobility. Offering the user with the possibility of giving up all worried that included things like the length of the cable, the timeframe it took to install a classic router as well as the reduces costs of finishing the network connection, the wireless routers are a real trend these days.

Because such a router allows an increased mobility for a notebook user, and because the notebook sales have also exploded over the last couple of years, the market for wireless devices is flourishing right now. Great wireless producers like D-Link, Linksys or 3COM have enrolled in a race to enhance and perfect the wireless fidelity standard.

When the Wifi standard was launched along with wireless routers, the maximum transfer speed reached about 1-2 mb/s, and now we can enjoy devices that reach 1024 mb.

Next to the classic laptops and desktops, more and more producers have implemented wifi modules in game consoles like Sony PSP. PS 3, Xbox 360, Nintendo Wiii, mobile phones like Nokia, LG, Motorola and many more, smartphones, digital photo frames, printers and so on. All these new devices make a wireless router some kind of wireless heaven of accessibility for the user, regardless if he wants to use a notebook or a desktop, or a game console, printer or phone. Users that do not have a wireless router and are connected to a broadband router can use an access point or a hot spot to gain themselves wireless signal.

This device can easily replace a router in cases in which it will be used for areas that do not go over 100 meters.

With all the advantages that the wireless routers are offering to users, they did not reach perfection yet, and their main problem remains security. Even if there are various types of efforts conducted to improve their security, even the safest networks are still far more unsecured than broadband networks. Broadband routers also have greater traffic speeds than the wireless ones, and the prices are a bit lower.

But since they do not offer the needed mobility, people dont care that much about they aspect, when they know they want to take the laptop along in bed with them and watch a late night internet movie or chat with distant friends or even finish up the last minute adjustments to tomorrows presentation project.

The most popular way of installing a printer on a local network is to install it as a unique and device on the network and then each computer from the network has to have the printer software installed to see it and use it.

If you are not sure what type of printer you want to use, decide if you want:

Install a wireless printer. These printers use wireless cards that are included in their hardware profile and they are connected to a power source other than the one of your computers. After you turn on the printer, you have to read the manual to be able to set the wireless connection to every computer in the network. The security options for wireless printing are determined by each printer type.

Connect a printer directly to the network. In order to do so, you have to connect the printer to your network hub or router. How to install these printers depends on whether your printer and the network device use an Ethernet, a USB or some other type of connection. You will also need to document on installing information or on ways of installing provided in the users manual.

Connect more printers directly to the network. To do this, your hub or router has to be able to support more direct printer connection.

Installing a printer on the network. This step means that you have to make computers from a network see the wireless printer. You will basically need the installing cd and the printers manual.

Connect to a wireless network printer. After the printer has been successfully installed on the network, you have to add a printer connection on every network computer.

1. Open printers by clicking Start, Control Panel and then Hardware and Sound, and finally click Printers.

2. On the toolbar, click Add a Printer.

3. In the Add Printer Wizard, select Add a network, wireless or Bluetooth printer and then follow the steps provided by the wizard.

Some people get a little bit scared when it comes to setting open printers. Now that we have many WiFi printers arriving on the market it’s making it much easier to share so that everyone on a small network and print directly without having to worry about patch cables. If you are having difficulty with your particular printer there are many support forums online that will be able to help you here we have just given you some guidelines for Treo has helped.

Over the last 5 years online gaming has moved from being a specialty niche available only to hardcore gamers with deep enough pockets to afford a war-horse gamer PC to establishing a solid foothold in the mainstream market of console games.

Before you can enjoy this new online community and team up with or compete against others across the globe you’ll need to get your console connected to the internet and while some consoles like the Playstation 3 come with WiFi wireless abilities built in, Microsoft has still not seen fit to follow suit.

This means that if you are the proud owner of an Xbox 360 console, you have two options. You can…

a) Setup a Standard Network Connection by plugging one end of a basic CAT5 ethernet cable into your game console and the other into your home network router in order to gain internet access through your high speed connection. Of course if fishing long lengths of cable through walls and under floors is not your idea of a fun Saturday afternoon, then you’ll probably want to go with your second choice which is to…

b) Setup a Wireless Network Connection - many people already have a wireless router in their home which the use to connect their various home computers to the world wide web. If that’s the case for you, then you’ve already won half the battle of getting your system up and running on Xbox Live. Now all you need to do is get ahold of an wireless gaming adapter.

Most people will simply choose to pickup the Official Xbox Wireless Adapter from Microsoft, but before you do you’ll want to know that by shopping around (usually on the internet) you can get a wireless gaming adapter for a lot less…usually anywhere from 30-50% less to be exact.

Now to some this may not be much, but on the other hand if you’re a parent who just bought your kids a new Xbox 360 for a birthday or Christmas present and were a bit surprised that the one game your hard-working, struggling to get straight-A student wanted to play requires an internet connection, this extra cost may come with a bit of sticker shock!

That being said, there are Xbox 360 Wireless Adapters available from quality manufacturers like Pelican and Linksys that will get your 360 plugged into Xbox Live with the same speed as the more expensive brand-name version. Either way, the choice is yours.

Once you’ve got your wireless adapter in hand simply power off your Xbox 360 console and plug the adapter into the proper Port on the back of the system. The official adapter uses a USB connection and doesn’t require an external power adapter, but some of the other versions will need to be plugged into a power outlet as well. Once this is completed the last step is to power up the 360 console.

The Xbox is smart enough to search for a wireless signal and connect to the internet itself. From here all you need an Xbox Live subscription. Most of the console packages come with a free trial membership to Xbox Live, so that’s usually taken care of to get you started.

You should be on your way to online gaming nirvana and usually the only other thing to watch out for is Wireless Security Settings. Many families wisely secure their home wireless router with some type of encryption protocol. If you’ve done so then you’ll know what I’m talking about and SHOULD be able to recall where you’ve kept your encryption key. That’ll be good too because you’ll need to input that code into your Xbox console’s settings in order for your Xbox 360 wireless adapter to work properly.

One final tip is to try and position the console as close to the wireless router as possible. Too much distance between the wireless gaming adapter and the wireless gateway can result in game lag and even lost connection problems. Proper positioning can solve these types of issues before they even begin.

Brian Kurtz as the father of three was frustrated to learn that he needed an expensive xbox 360 wireless adapter in order for his family to play online games. Feeling gouged he setup a site specifically for those looking to get a significant discount when buying a wireless gaming adapter which can be found at http://Xbox-360-Wireless-Adapter.com

Windows Vista wireless networks do pose a few types of problems when it comes to adding new computers to the wireless network. They will ask for a network security password even for networks or computers where the password has not been set, they will sometimes refuse to see a network or refuse to connect to a network, especially when the other computers on that network are not running windows vista.

If you want to add a laptop that is running Vista on a wireless network that already has 2 computers running Windows XP, and there is no way the laptop wants to connect wirelessly to either of the computers, you can add the laptop manually. In order to do this, keep in mind that the laptop has to see the network. Usually, the router connection is possible and the vista laptop does connect to the internet using this connection, but it can not see other computers belonging to that network and at the same time it can not be seen by them.

Before you start anything, make sure there is a network password for the Vista laptop and also share a few folders to the network, so that you will be able to verify a lot easier if the network connection between devices is in fact available or not.

Here are the basic steps of adding a wireless computer that is using windows Vista to a network.

1. Log on to the computer.

2. Click on the Start button and the Click Connect To.

3. Here you will have to choose the wireless network from the list that appears and then, click to connect.

4. You will be prompted for the security password of the network, and you have to enter it, and then click Ok.

5. You will get a confirmation once you are connected to the network.

To make sure everything is ok and files can be shared and seen between computers, open the Network by clicking Start and then Network. Here you should see the computer that youve just added as an icon and next to it all the icons of other computers and devices that are already part of the network. Access the new added computer.

The folder should open and you should be able to see the shared files. If an error returns and still the Vista computer is connected to the network, try and see if file sharing is enabled on it. In some cases people forget to enable this is vista and this is the main reason why computers can not see each other on wireless networks in which some run windows vista.

You’ve just done the wireless connection on your computer and you are already feeling pretty much like an It technician. Everything is nice and peachy until you notice that if you go a few meters away from the router the signal is dangerously decreasing. This decrease in wireless signal power can be a cause of the conditions youve organized the network in.

Remember that location is very important. The place in which you place the router will determine in a very high degree the coverage range. Depending on your apartments architecture, place the router or the access point centrally. If this is not possible, its no problem, there are other ways of increasing the coverage range of the wireless signal. At this point you need to read on, for other suggestions.

Move the router away from walls, metal objects and never ever place it on the floor. If it is very close to walls and objects it will get a lot of interference from them and the resulting signal will be as weak as it gets.

If you have a large budget, you could try buying a better antenna for your router. Some devices work only in one direction, as opposed to the included antenna. If it emits signals in one direction and not in circles, the signal will travel longer distances in that respective direction. Just turn the antenna around each time you move location or if you decide you need coverage in other direction.

You can also increase the wireless signal by buying a network card that is newer and enhanced. Some wireless cards use external connections on USB and they function better getting a greater coverage area. These are not expensive at all.

Still, if you like you network card and dont want an external one, you can opt in for a wireless repeater. The wireless repeater or access point will permit you to increase the coverage area of the wireless network, more than two times. It must be also placed as central as possible. Never place it near the router, because if you do so you are missing the whole point of this device.

Another advice is to change the routers emitting channel. Read the instructions manual and you will find there more details on how to change the channel. If you have a weak signal, changing the channel can sometimes improve it, in those cases in which the first channel was too used in the area.

Some people choose to make their own wireless booster or antenna out of simple things like empty metal cans. If you want to experiment, there are lots of guides around the internet that can turn you in a little inventor.
