Wi-Fi Spectrum Analyzers: Optimally Configure and troubleshoot 802.11 Wireless Networks
Wi-Fi wireless networks have grown in popularity in recent years and are found ubiquitously in the economy, industry and at home. Wi-Fi networks in the 2.4-GHz Industrial, Scientific and Medical (ISM) band - a public that is not licensed by the FCC. Many types of wireless devices compete with Sky in the 2.4 GHz ISM band - and this leads disorders that adversely affects the performance of a wireless network. A 2.4-GHz spectrum analyzer is theTool of choice for the detection and identification of interference sources and provision of information, the optimal configuration of a Wi-Fi network allows.
Overview
With wireless systems it is very difficult to predict the propagation of radio waves and the presence of interfering signals without the use of test equipment. Radio waves do not travel the same distance in all directions - instead of walls, doors, elevator shafts, people and other obstacles offer varyingDegree of damping, which the radio frequency (RF) radiation that cause irregular and unpredictable. To ensure optimum reliability and throughput for your Wi-Fi to (802.11) wireless network it is necessary to recognize and identify sources of interference that may negatively on his performance.
There are a variety of electronic devices, the RF transmission of energy in the airspace. Wi-Fi (802.11 b / g) operates in the 2.4 GHz Industrial, Scientific, and Medical(ISM) band. This particular frequency range (2.401 GHz to 2.473GHz) is public and their use does not require approval by the FCC. As a result of this band tends to get rather full - not only with 802.11 devices, but also microwave ovens, Bluetooth devices, cordless phones, baby monitors, audio / video transmitters, wireless cameras, etc.
Optimize Professional installers of wireless computer networks to try to reach their customers Wi-Fi network a strategic choice of aSubset of the 2.4-GHz band for use by their wireless network devices. The 2.4-GHz range from 2.401 to 2.473 GHz is divided into 11 each, 22 MHz channels. Note that 2.473GHz - 2.401GHz = 72 MHz, 11 times 22 MHz or 242 MHz. So, how fit is 242 MHz to 72 MHz? Answer - the channels overlap. An installer is the wireless router or access point (AP) be configured to channel 6, and then uses all data communication will occur over the range of frequencies associated withChannel 6 (ie 2.426 GHz - 2.448 GHz). But if other wireless devices (802.11 or non-802, 11) are also transmitting on this frequency range will suffer from your wireless network among them. So, if a wireless network or troubleshooting a weak performance is, it is important that a channel that is not subject to interference from other select devices - that is, you do not want your wireless network with other devices provide the same range of competingFrequencies.
Wi-Fi Diagnostics tool
There are two categories or types of tools for helping you choose the best Wi-Fi channel for your wireless network available - WiFi Scanner (ie, 802.11 discovery tools), and 2.4 GHz spectrum analyzers :
Wi-Fi scanner, or 802.11 (WLAN) discovery utility. The best known in this category is NetStumbler (http://www.netstumbler.com/). The discovery tool is the Service Set Identifier (SSID) report for each accessPoint (AP) it detects, along with the channel used by the AP. This works is that about every 100 ms, an AP sends an "I'm here" beacon - and the discovery tool (on your laptop, and with its 802.11 wireless adapter) takes the beacon and adds the SSID to its list. In addition, the discovery may Utility Report SNR (signal-to-noise) ratio for each AP, which as an indication of how close the AP is your current location. Although thisuseful information, it does not tell you what not to employ-802.11-devices, and, as the AP. This is could be your laptop sitting next to a microwave, send all types of RF energy into the room, and the discovery tool would be unaware of its existence. The Discovery program knows only about 802.11 devices - devices which transmit RF energy to the 802.11 protocol - and can not see, not-802, 11 transfers. Here is an analogy - you are in a major isAuditorium and you hear someone yell across the room sometimes, "Hello, I'm Joe!". Joe is an Access Point, and he occasionally sends a signal to leave, who's out there know that he is there. It could be that Joe is really busy and talk to many people, or he can be with him. Or there are a lot of noise in the auditorium, it would be difficult to carry on a conversation with Joe from a distance. The discovery tool can not help you with that - just listenJoe's occasional beacon "Hello, I'm Joe!".
2.4 GHz Spectrum Analyzer. This is the tool of choice for the detection and identification of sources of RF interference. Spectrum Analyzer is a fundamental tool for monitoring radio frequency (RF) signals are used - they give you a better picture of the RF environment to help identify and find devices interfering with your wireless LAN (WLAN). Typically they are based on a 2-dimensional representation, where the vertical axis (Y axis)represents the magnitude of a signal and the horizontal axis (X axis) is the frequency of a signal. Dedicated hardware spectrum analyzers can be in the tens of thousands of U.S. dollars they get (employ many arrays of analog-digital converter). Recently, PC-based analyzers have appeared on the market. But they are also quite expensive - close to $ 4000 AirSleuth is an affordable 2.4-GHz spectrum analyzer shows available Nuts About Nets, LLC, that RF data in aVariety of diagnostic views that help to reveal the presence of interfering devices and then choose the best channel for your wireless network.
Examples
Click here to see included 5 Examples of measurements with the AirSleuth 2.4-GHz spectrum analyzer. In each picture there are 3 items to take note of:
a. The maximum value on the y-axis
b. The horizontal white lines indicate that the limits of the 11 overlapping channels 802.11
c. TheLocation (ie frequency) and height (relative signal) of the large HF Summit
Figure 1 In this figure, the horizontal white line shows the limits of 11, 22 MHz channels in the 2.4 GHz band. Note how adjacent channels overlap.
Figure 2 The airspace is relatively quiet and there are no wireless devices transmit in the 2.4 GHz band. Note the maximum value on the y-axis is '3 .0 'relative signal units --this is small. The reason you see peaks (and starting) is not quite flat, the display employs automatic scaling so that (the highest peak regardless of how small it really is) filling the screen. We know what looks background noise, since the maximum value on the Y-axis <10.0.
Figure 3 is running a microwave oven. Here you can see that it radiates RF energy over the entire 2.4-GHz band.
Figure 4 is a 2.4 GHz cordless phoneturned on. Note the height of the peak near channel 1 around "140" units and the peak near the channel 11 is around '110 'units. These are strong enough to knock out wireless networks are configured to use either channel 1 or channel 11. Moreover, because of the way that channels overlap the first peak would probably also interfere with a wireless network with channel 2, and the second summit would also interfere with wirelessNetworks with 9 or 10 channels.
Figure 5 shows the course of the activity from a wireless network (configured to channel 6) to use, since it operates a large stream of data transmitted.

To a laptop wirelessly, a signal is necessary to either require having a home network or public Wi-Fi location, and a wireless card or built-in Wi-Fi connection for a laptop to record the signal.
How do I connect a wireless printer with a wireless laptop?
Printers that are networked with each other will come with either a wireless adapter or a network adapter.
As the question states wireless printerThen let us assume that it has a wireless adapter. You can then connect it directly to a wireless router or you can use it in the so-called ad hoc mode.
If you be aware of ad-hoc mode, then that pressure to monopolize use your wireless adapter in your notebook.
There are some good step-by-step instructions on wikiHow, "Setting up a wireless printer connection set.
Are all wireless laptops?
Most laptops today(Oct. 2009) have an integrated WiFi, so you need not buy a wireless adapter for the laptop.
How do I connect an old laptop with a wireless home network?
Depending on how old the laptop is not likely via integrated wireless as do most new laptops today.
Assuming you already have a wireless home network installation, you must include a wireless network card of a type for your old laptop can too. EvenHowever, there are a number of different wireless adapters, the two are primary today for laptops either a PC card, sometimes called a PCMCIA card or a USB wireless adapter means.
The PC Card is about the size of a credit card and fits into a slot on the side of your laptop. Before buying make sure that your old laptop has such a slot.
The wireless USB adapter is, of course, assumes that your laptop with a USB port to be available on.

Setting Up a Wireless Router
With a wireless router computing life a lot more fun. Why limit yourself to the computer at the same place you took it out of the box work? Setting up a wireless router is simple and allows you the freedom, the Internet, files, access printers, and much more, from virtually anywhere in your house or garden. Before you shake your head to set up a wireless router on your own, trust me, if I can do it allcan.
Here are some simple steps for setting up your wireless router.
Choose the right wireless router for your needs.
When you walk into your local store, Best Buy or other computer, you'll see that they have a variety of routers available. Basically, there are (3) wireless networking technologies on the market, 802.11a, 802.11b and 801.22g. So, what are the differences between these wirelessTechnologies?
802.11b wireless protocol is the oldest version of wireless networking technologies currently available. While 802.11b Wi-Fi hardware can be found at discounted prices, I would urge you to avoid them. 802.11a is in range and capacity compared with existing 802.11b and 802.11g limited. Why, then, your first wireless network with the oldest technology set.
802.11b wireless protocol (11Mbs) is by far the most common wirelessTechnology in use today. If you choose this wireless protocol, you will be well. But why not with the latest and best available wireless protocol?
802.11g is the best wireless technology on the market and all new computers with integrated wireless cards use this protocol. 802.11b wireless protocol has been replaced by backward-compatible 802.11g (54Mbs). This means that if you have a 802.11b card on some of yourComputing devices, you can use an 802.11g wireless router, without the need to replace your wireless card. If you have the option, I would recommend buying 802.11g cards for your computer as well as the maximum benefits of this wireless network technology to obtain.
Connect your wireless router
Before you begin, be sure that a paper copy of any instructions or the router manually before you.Sounds easy, I know, but you'd be surprised how many people neglect this essential step. Ok, let's get started!
The first step will be to power down your DSL or cable modem. This will be achieved by pulling the device out of the sockets.
Then plug the wireless router to the modem. I would recommend that the distance between the router and modem as close as possible. I have both a modem and wireless router settings on this pageside by side on my desk.
With the included wireless router, you should create a short cable. This is your network cable. Connect the network cable into the wireless router into the port labeled Internet, WAN or WLAN. This name varies by brand of wireless router you bought. It does not matter which end of the network cable to connect to the router, since the same type of connector is used at both ends.
Once youconnected the network cable to your wireless router, the other end of the cable to your modem. The modem is only one port available. You will hear a "click" when a secure connection has been established.
You can now re-insert the cable that provides your Internet access back into your DSL or cable modem.
At this point you will want to power your modem. The modem should always driven to be first. Allow a few moments for the Internet connectionSynchronize with the modem.
It is now time to configure your wireless router. Temporarily disconnect the network cable from the router and modem. When you have completed this, connect the network cable to each port of the wireless router is not known as the Internet, WAN or WLAN. They are probably at least 4 open ports, it makes one's will. Then connect the other end of the network cable to the computer. This may seem confusing, you must, however, ato enable direct connection between the router and computer configuration.
On your computer, open an Internet browser and enter the address to make your specific wireless router meets.
Router address USERNAME PASSWORD
3Com 192.168.1.1admin admin
D-Link 192.168.0.1 admin
Linksys 192.168.1.1 admin admin
Microsoft Broadband 192.168.2.1 admin admin
Netgear 192.168.0.1 adminPassword
If you typed the address into your browser, you will be prompted to enter a username and password. Refer to the table for your individual information. While in configuration mode, you have the option of your password, which I strongly suggest to change.
Next you must set your network ID, or SSID. This name need not be lengthy, but choose something that is unique, yet simple enough for you to remember.
Protect yourNetwork. You also have the option of either the security of your network or leave it "open." While the network "open", anyone within range of your wireless router's signal will be able to access your network. If you live in a place in a development or an apartment, there is a good chance to be someone riding on your network .. is with your Internet access for free or degrading access to your quality. It is a good rule of thumb, access to networks and computers, if safepossible.
To secure your network, choose the WEP tab or option. WEP stands for Wireless Encryption. You will be prompted for a password or password. We have already addressed you, your administrative password from the default, so let's move on. Make sure you select Apply or OK after your selection.
Disconnect the network cable from the computer, and close as before. One end of the network cable goes into the port on the wireless routerMarked Internet, WAN or WLAN, and the other end to connect to your DSL or cable modem.
After a few brief moments of an icon should appear on the desktop, you will be alerted, a wireless network has been detected. Right-click on the icon and select "View Available Wireless Networks".
If you are not your network, click the Refresh button from the menu. Once your network is visible, click it.
If WEP protected your wireless network, you willasked to enter your password or password. If you decide to leave your network unprotected, you will be advised that you try to access an unsecured network. Select your network and click "Connect".

Optimizing the Router for better Wireless Connectivity
If you are downloading a large file and it comes to an end, you will receive a Skype call from a customer in London, without warning, Wi-Fi connection drops, leaving downloading and VoIP call in chaos. They will try again the wireless connection, but your router, though blinking satisfied in your forward, seems to be off. After three hours, without reason, Wi-Fi connection miraculously resurfaces.
Wireless networks can be a simple and yet gives you aHeadache, It's great when it works and a mind-numbing frustration when it does not. A common complaint among many, which is shifted to Wi-Fi that their wireless connection mysteriously slow in and out of the frequency.
These steps will help you a stable, always-on, the wireless connections.
1. Replace your cordless phone. Cordless phones are among the worst sources of interference for wireless networks. You want at a higher power outputas Wi-Fi gear, so they talk louder, and therefore much more difficult, and they tend to transmit frequently, especially when the handset and base station are separated. Some 2.4GHz cordless phones you leave a channel, in which case you can try separating the phone's frequency from the frequency of your wireless network. For example, on your phone 1-channel and wireless routers to 11 channels. If your phone does not leave a channel, try someDistance between the phone and the router. In general, it is not a good idea, a cordless phone next to a wireless router instead. If this does not help, consider replacing your phone with a 2.4 GHz phone 5GHz. In this way, your phone and network do not share the same airspace and not disturb each other.
2. Expand your wireless network. The farther you are blocking from your wireless router, the greater the potential for interference or slow downYour connection. For example, you may be able to connect just fine in your house, but on the terrace, you can an intermittent connection that disappears when your neighbor has used her cordless phone. The signal on your patio may be too weak to overcome the interference from a neighboring house. You can strengthen the connection with antennas or repeaters, or you can use a power-line bridge to import the connection from the router to your patio and lead to aPower-Line-Access-Point. Removed instead of the weak signal from your router, you now have a strong signal transferred from an access point where you want your coverage area to support.
3. Change channels. Interference is a likely cause of intermittent connections, as described above. All 802.11b and 802.11g networks operate at 2.4 GHz, in a small band of spectrum once used primarily by ham-radio hobbyists. Today, these radios, gear, plus other Wi-Fi, BluetoothDevices, cordless phones, microwave ovens, baby monitors, surveillance and wireless devices that all the quantity of the spectrum. When these devices compete to stay in the same airspace, they interfere with each other, which may block the other signals. Fortunately, there are ways to avoid and minimize disruption in many situations. In the United States, 802.11b and 802.11g devices can be configured to operate in one of the 11 channels. Unfortunately, these channels overlap with adjacentChannels, so you only 3 non-overlapping channels are available: channels 1, 6 and 11 If you and your neighbor both have a wireless network that are set in both 6-channel, you can experience interference. You can find the problem by resetting your wireless router to another, preferably in non-overlapping, channel situation, in this case, either 1 or 11

The need for an Outdoor Wireless Router
When you think of computers, then you think of them are inside. But in today's world we need things to go with us. So you can see people all the time in the park with their laptops and the like. Also on site you can see people outside with computers. Here is an outdoor wireless router could prove useful. This is a router that you can have outside, and it is safe to use. This is a great way to make every effort to keep the connectionInternet, no matter where you are, and you can still be safe. Finally, you do not want that on your server to connect and have access to your computer.
The data that is passed through these outdoor wireless routers are as good as the inside Ones. However, there are a few things you should know about an outdoor wireless router. First, you need to know that they have an outdoor wireless router does not mean that you should leaveit outside. This means that they stand up to changes in temperature can be much better than those inside. Moreover, they are usually waterproof. However, this only means that it can be wet and that's nice. Just like when it begins to move, your router is not going to be broken. You should not leave it in water for a long period of time, because water can get into the system, and it will break it. With a wireless router in the open is nice, but you can still have a NIC cardfor your computer.
Most of the time an outdoor wireless router around one on a longer range than an indoor pool. This is so you can even further away from the router and use it. But to a lot of time, as you continue away, it will remain hard connected to your computer with him. That is where a network interface card comes into play, or if a network card. This can help you connected to the system, even if you are far away. These routers are secure and safe for youuse.
You have not yet worry about sharing data with your computer worries, because it is about being safe, so nobody can look at them. If you have a dying need out there and use your computer, then this outdoor wireless router could be just what you are looking for. It would be ale to answer all your needs, and better than your internal router. In fact, buy a lot of people that work outdoors routers for the home, just because they better. However, they arecost more money most of the time.

Secure Your Home Wireless Network, and keep hackers out
One of the most important but under-implemented functions of a home wireless network is security. Many people are worried only about file sharing and network printing. But do not understand a lot of people underestimate the need for security or simply. Safety is because unlike traditional wired networks is important, are transmitted wireless signals over a wider range and therefore can be easily picked up.
With the growing threat of identity theft, taketo secure the necessary steps for your wireless network. There are some minor threats and the greatest threats to your personal information. On the low side, an intruder can easily connect to your wireless network unsecured and for free internet access. This is called piggybacking. These are minor threats to your privacy.
A big threat is a hacker who is looking to attack your network and hack into and access to your files and personal data. As soon as they canstart quickly and easily steal your identity or sell to someone.
Wireless security can be implemented by following a few guidelines. One of the most important features is MAC address filtering. Every computer has a unique MAC address. In your network configuration, enter the MAC addresses of your PCs and laptops. All other computer that is not specified in your network, blocking access to them.
Another important feature is to disable the network securitythe broadcasting of the SSID or the name of your network. It is best to refer to the manufacturer's documentation for individual circumstances. Most of the required safety features are built into the wireless router and this is the first point, which it secured. Many of the security settings are disabled by default. Make sure that it for the best security.
You can save and manage your network even if you have the time or you can buy a home networking software package whichdoes this for you automatically. There are some good programs available for under $ 30, which is a secure and repair your home network.

Installing Linux on the WRT54G Wireless Router
The WRT54G is a wireless router made by Linksys. A few years ago his Linksys WRT54G firmware source code is the open source community the opportunity to release their own versions.
Installing Linux on your wireless router has many benefits and I believe that some risks. The only risk you do face turns the router into a "Brick". Now this comes as a great opportunity to take, but it seems there are many options when upgradingfails. Even if you follow the installation instructions for each wrt54g firmware distribution, you will have no problem.
Typical ways to "brick" your WRT54G router is: try the firmware upgrade over a wireless connection to install interrupt the upgrade, and finally at the wheel or drive five minutes after the upgrade.
General rules to follow are:
1. Always an upgrade from the original Linksys firmware wrt54g no otherFirmware distributions.
2. Put back your firmware to factory settings.
3. Can I upgrade from a wireless connection.
4. Turn on your router for about five minutes after the upgrade.
5. Make sure your firmware for your router should have some firmware versions for the WRT54GS (WRT54GS with SpeedBooster mean), and the regular WRT54G.
6. Follow the instructions for each given FirmwareDistribution.
7. Enable boot_wait function on your router. This option gives you the possibility to resume uploading from a failed upgrade with tftp a new firmware.
Linksys provides tools with which you will not recover from distributions. There are many different wrt54g firmware distrobutions Pick. Some have special purposes: as used in a wireless hotspot or a radius server. Do your research before you install and alwaysThe precise installation instructions.

How to choose the best broadband router for your network
Optimal performance for your broadband router is what you are, if you want to properly connect to the internet and need. It was the right brand of router election means. Save before buying random router from your computer, you have to think twice first, if the properties of what you have to buy from good enough.
There are many features that should be included in the router you use. It must have security features like firewalls, and it must be easyYou can connect to other computers. Here are some more things to note:
Tip 1: Check the connectors and sockets on the router. A typical router has four Ethernet ports on the back and one WAN port. When you connect to your wired computer, you can only use up to 4 computers. However, it is an option for those external to a switch to connect to. Connect this to the router. That has a lot of ports that can still the files on yourother computers.
Tip 2: Find out if you need to wire or wireless router. It also depends on your Internet provider. If you use a broadband router, your network is always wired. The network has, with the router to be compatible.
If you use wireless connection for your internet is safe, it is compatible with a wireless router. However, you should contact your provider if you are not sure what to askcompatible. Some Internet providers offer their customers can use the router. In this way you can be guaranteed compatibility.
If you have no Internet connection is not installed, look at the wireless Ones. So that you can connect more than 4 computers. You only need the wireless adapter to the back of the router and plug it is already signal is transmitted to wireless devices.
Tip 3: Before you buy, you should let go the head, which functions youwant to see in your router. Not all routers have the same properties. Those who better range and improved security features are ideal, but they are more expensive. When these functions are what you need, write it down and allot a certain budget for IT. If you only use it for your home and a simple router, what you need is also on a note of it and set your sights on brands with only simple functions.
Tip 4: Compare brands. Make sure to read reviewsfirst and find out if that brand is really reliable.
