Wifi Sniffer

Wireless devices are becoming more and more commonplace. For some, a wireless connection network problem can be an expensive and annoying experience. Spotting the presence of a wireless device can be critical for business or personal communication. A WiFi sniffer is an interesting new tool that may help you find a signal when you need it the most.

Hotels and airports allow access to networks for business and leisure travelers, and networks are often available to people who may work or study from a park bench, a coffee house, or a shopping center. Mobile WiFi antennas give truck drivers, RV vacationers, and other mobile individuals unending access to the Internet, so they won't have to keep their laptops or PDAs at home, and can consistently stay connected to their families or their employers.

Today, WiFi users can now purchase a sniffer, which is a wireless tool that detects the presence of other wireless devices, calculates the strength of their signals, and gives a report to the owner on the locality of the access point.

A WiFi sniffer would be a valuable tool for campers, backpackers, and other outdoor enthusiasts. If you were to become lost while hiking or traveling in the wilderness, by finding the location of other wireless devices, you may be able to get to another WiFi device, enabling you to get help, or find your route back to your camp or destination.

Similarly, if you were to misplace your own wireless device, such as your notebook, bluetooth or PDA, your sniffer can help you to locate it; or if you are having a wireless connection network problem and are in critical need of some other wireless device, your sniffer would give you a report of other such devices nearby.

These are all good uses for a WiFi sniffer, but network accessories such as these can likewise be used for more nefarious intentions. For example, a hacker intent on sabotaging or debasing the users of any WiFi network could use his or her WiFi sniffer to find the presence of wireless devices, set up a fictitious WiFi network, or hack into the existing network, and steal personal information from the users of the other wireless devices.

Likewise, the owner of a cyber café intent on stealing guests from a competing café could utilize their sniffer to calculate the network traffic of their competitor, and then decide to lower the cost of accessing their network to lure customers away from their competitor. Or, the managers of a shopping mall might use their device to count the number of people who connect to their network, and then raise the cost to gain more profit from their buyers.

Like most tools, a WiFi sniffer can be used for good or evil, and it is contingent upon the reasons an individual uses such a device. But if you are struggling with a wireless connection network problem, being able to access another nearby network can be a great help. If you are interested in purchasing a WiFi sniffer, be sure to do a complete internet search on the range of products for sale. Get information on mounting your device, and connect with current owners to find out what other accessories you may want.

Network Address Wireless Problem

If you are having problems with your wireless connection network address then there are certain steps, which you can take yourself, which may help to rectify the problem, without having to turn to an expert for help. Below we provide you with a few steps that you may want to try if in the future you have a network address wireless problem.

First off, check the connection between the wireless router with that to the modem you are using. You need to make sure that all the cables have been inserted correctly and that the lights, which show the connections status, are on.

If you discover that there is a problem between these then you need to spend some time checking the following:-


1. If you can replace the cables that are connecting the wireless router to the modem as this may have become damaged. It is important that you check in the manual that come with your router to see that in fact you are actually using the right cables.

2. After replacing the cables you discover that the status lights remain off then it might be an idea to try and connect another device to the network to see if this is affected at all. If this does not work then it is a good idea to check the port configurations at either end of the network and reconfigure if you need to in order it is running at the right speed and using the right duplex mode.

3. Even after you have carried out all the above and you still find that you have no network connection then check to make sure that the wireless adapter, which has been, installed n your device is working correctly. For those who are running Windows applications on theirs you just need to go to control panel, then network connections and verify that it is showing as enabled.

4. Next you will need to check and verify that the settings on your Wireless LAN are correct. This will also help you to identify the actual port IP address as well as the subnet.

5. After checking and verifying the LAN settings you now need to move on and check/verify the TCP/IP settings. To do this you will need to once more go into the network connections panel. After going into the TCP/IP settings you need to click on the repair button and hopefully this will help to rectify the problem that you may well be having with your network address.

However if you find that after trying the various different things mentioned above you have not been able to fix the network address wireless problem it may be time you looked more closely at the hardware you are using. Often you may find it is a simple case that the wireless adapter, the router or the modem you have in place are not functioning correctly and need to be replaced.

Playing Video Games With A Wireless Controller

One of the best video gaming system accessory on the market today has to be the wireless controller, which is available for most video gaming systems no matter which one you own. With a wireless controller, video gamers no long have to worry with troublesome wires getting in their way during game play.

Most wireless controllers have an off and on switch built right in, which enables the gamer to turn their video gaming system off and on where ever their controller is. The majority of the wireless controllers being produced have a range of thirty foot so that gamers can move away from the console to answer the door or phone if needed. Also, the majority of these wireless controllers require two AA batteries in order to work and will last for up to forty hours. The advanced hardcore gamer really needs to be prepared to either buy extra batteries or to go ahead and put the extra money into their effort and purchase rechargeable batteries. One great feature with most of these wireless controllers is that they have a built in feature to let gamers know when the batteries are getting low, which allows the gamer time to pause the game they are playing and change out the batteries.


These wireless controllers are designed to fit the gamers hands much more comfortably and the buttons are easier to use as well. Most wireless controllers have the capability to plug in a headset, which allows the gamer to communicate vocally with other gamers throughout the world. Most video gaming systems have the capability to allow up to four wireless controllers to be connected to one gaming console at one time. When gamers get together and play each other in a video game battle, most the time they get in a big mess with their wires getting tangled up together. However, the advantage of using wireless controllers is that gamers never have to worry with getting their wires tangled up together again.

Some wireless controllers that are being produced may seem bulky and heavier than others due to having to put batteries into the controller itself. When gamers decide to purchase a wireless controller there are several on the market to choose from. Some wireless controllers have vibration feedback that the gamer can adjust, which can give the batteries a longer life time. When the vibration is adjusted the gamer will have the ability to feel a car as it slides across the track or flips over and over. These wireless controllers can be purchased at any local video gaming supply store, most toy stores, and on-line at a variety of web sites.

With a wireless controller, gamers no longer have to worry about getting too excited while playing their video games and pulling their video gaming console system off the shelf or the controller itself out of the video gaming console. Now gamers will have the ability to sit down, lay down, stand up, or jump up and down if they desire while playing their video games and never ever have to worry again about damaging their video gaming console system when getting overly excited.

How To Hook Up A Wireless Access Point

On a daily basis I get questions about setting up a basic wifi access point to cover a certain area of ground. This is normally outdoor and many many times these simple installations are in a RV park, marina or camp ground so I figured I would share the wealth. A typical one access point installation has a few key components and some optional ones.

Key Components:

* The wireless access point or base station (if you couldn't guess)
* POE Injector
* Omnidirectional antenna
* Cabling (RF for the antenna and CAT5 for the POE and network)

Optional

* Lightning arrestors. These are recommended but the system will work without them. You would need one lightning arrestor for the RF side (antenna side) and for the network side of the access point.


Here is what your set up would look like:

You will notice that I did not specify any gains on the antenna as every installation is different but in the 2.4 GHz range I find that the 9 dbi omni antenna with 7 degrees on downtilt works great.

OK so I know your next question. How much area will this cover??? Well in the world of wi-fi the two most used words are "It Depends". You'll hate to hear them but you better get used to them as there is never a clear answer. RF signal propagation depends on many factors such as interference, environment, line of site and the most overlooked factor CLIENT TYPE!

Most people understand interference and line of sight but if not you can feel free to read more about it in our growing wireless FAQ, here. However, the one most people do not understand and sometime refuse to understand is that client type can make or break your wireless network. How so? Well...lets take an RV park for instance.

An RV park wants to set up a simple access point in the middle of the grounds to serve its 70 RV users. The client then spends time reviewing access point specs, finds a perfect bridge with a great mix of price and performance. Buys the highest gain antenna he can find and makes sure that there is no excessive loss in the RF cabling. The items arrive via UPS, he sets them up perfectly, similar to the setup shown above and starts walking around with his laptop running netstumbler BUT, he is only going a 3rd of the distance he was expecting. This can't be right he thinks and starts troubleshooting his new hardware. However, what he doesn't realize is that it has nothing to do with the new access point set up he purchased and everything to do with the low powered wifi card in his laptop.

Communication should always be looked at as a 2 way street. The base station (access point) can be uber powerful and transmit for miles but if the device receiving the signal a mile away can only transmits 300ft the base station will never hear the interesting things the client is saying and communication breaks down. I tried to illustrate this concept and hopefully succeeded but let me know if I blew it.

Bottom line is know your wireless application and build accordingly. Do not focus on one part of your wireless access point alone as you will never get the results you are after. Look at your wireless network as a system of components working together to create cohesive communication.

WLANMall specializes in wireless connectivity. Period. Whether you are a wireless service provider looking for wireless WAN or MAN solutions or an IT manager looking for internal local or building-to-building connectivity, WLAN Mall will help you find a customized, cost effective solution that fits your organization’s budgetary requirements.

Frequency Fundamentals of Wireless Networks

Wireless networks can be divided into two broad segments: short-range and long-range. Short-range wireless pertains to networks that are confined to a limited area. This applies to local area networks (LANs), such as corporate buildings, school campuses, manufacturing plants or homes, as well as to personal area networks (PANs) where portable computers within close proximity to one another need to communicate. These networks typically operate over unlicensed spectrum reserved for industrial, scientific, medical (ISM) usage. The available frequencies differ from country to country. The most common frequency band is at 2.4 GHz, which is available across most of the globe. Other bands at 5 GHz and 40 GHz are also often used. The availability of these frequencies allows users to operate wireless networks without obtaining a license, and without charge.

Long-range networks continue where LANs end. Connectivity is typically provided by companies that sell the wireless connectivity as a service. These networks span large areas such as a metropolitan area, a state or province, or an entire country. The goal of long-range networks is to provide wireless coverage globally. The most common longrange network is wireless wide area network (WWAN). When true global coverage is required, satellite networks are also available.

Many of the wireless technologies in the WPAN, WLAN, and WWAN categories transmit information using radio waves. For this to take place, the data is superimposed onto the radio wave, which is also known as the carrier wave, since it carries the data. This process is called modulation. There are many modulation techniques available, all with certain advantages and disadvantages in terms of efficiency and power requirements. The modulation techniques are as follows:

1. Narrowband technology - Narrowband radio systems transmit and receive data on a specific radio frequency. The frequency band is kept as narrow as possible to allow the information to be passed. Interference is avoided by coordinating different users on different frequencies. The radio receiver filters out all signals except those on the designated frequency. For a company to use narrowband technology, it requires a license issued by the government. Examples of such companies include many of the wide area network providers.

2. Spread spectrum - By design, spread spectrum trades off bandwidth efficiency for reliability, integrity, and security. It consumes more bandwidth than narrow-band technology, but produces a signal that is louder and easier to detect by receivers that know the parameters of the signal being broadcast. To everyone else, the spread-spectrum signal looks like background noise. Two variations of spread-spectrum radio exist: frequency-hopping and direct-sequence.

a). Frequency-hopping spread spectrum (FHSS) - FHSS uses a narrowband carrier that rapidly cycles through frequencies. Both the sender and receiver know the frequency pattern being used. The idea is that even if one frequency is blocked, another should be available. If this is not the case, then the data is re-sent. When properly synchronized, the result is a single logical channel over which the information is transmitted. To everyone else, it appears as short bursts of noise. The maximum data rate using FHSS is typically around 1 Mbps.
