Installing Multiple Wireless Access Points

1. Install one wireless Access Point to test range

2. Assign each wireless access point a unique IP address

3. Each wireless access point will have the Same SSID

4. All wireless access points will have the same encryption key

5. Point wireless antennas towards the center of the network

1. Finding your Wireless Range - Wireless access points will have a range of about 75-100ft inside, and outside (depending on your wireless antenna) miles. If you live in an older brick home your wireless signal range can be greatly reduced.. To find your wireless signal range and signal strength you will need to install one wireless access point in the middle of your work area and measure the signal. You can use a program called netstumbler to help you with this task. Once you have achived the necessary wireless signal overlap then you will be able to roam through out your work or business. Your wireless adapter software will choose the access point with the strongest signal but this will be transparent to the user

2. Unique IP -Next you will want to assign all your AP’s with a unique IP address not a dynamic IP address. Do not use the same IP adderess for each AP.

3. Configure AP’s - Configuring two or three wireleess access point is not very hard but when you have to configure more than that it can become time consuming. Thus some wireless routers will come with software that will allow you to configure one access point which will then configure all of your other access point for you.

4. Same SSID - Use the same SSID for each access point on your network. This will give you the ability to roam with out having to choose each network when you move.

5. Encryption /AuthenticationWireless Antennas - Choose which type of antenna you will need. Try to purchase directional antennas instead of using the default omni-directional antennas. Directional antennas will funnel your wireless signal towards your operational areas.

7. Placement - Try not to place your AP by outer walls. If you need to place your AP buy outside walls then try to use a reflector. This will help your signal stay inside your house as much as possible.

Accessing the Internet has always been a problem for all of us. There have been a number of times when was necessary to log in onto the Internet for an important reason, but it just won’t happen. You feel frustrated, because you’ve missed out on an opportunity to meet a friend in a chat room, or apply for a job someone told you about.

One innovation that is currently changing the world of Internet users s is wireless Internet access. Wireless Internet access provides you easy access to the Internet without having to go through the usual trouble of setting up your computer with wires and cables, as well as checking if these cables are connected to the right places. This type of Internet access saves you from the usual trouble of untimely disconnections. Without any wires and cables to cut off, disconnections are not a problem.

Wireless Internet access is a good option for those people who become quite restless when it comes to staying in one place for too long. This type of access to the information super highway gives you the convenience of hopping from one place to another, while doing your work on your personal computer or laptop. If you choose to do your reports out in your backyard, then you can and not have to worry about cables not reaching your location.

Downloading information and sending out data is not difficult with wireless Internet access. Accessing the Web through this method provides users a quick and easy connection. Data from Internet providers show that transfer of data using wireless Internet access is much e greater and faster than the usual way of hooking up to the Internet.

Wireless Internet provides detailed information on Wireless Internet, Wireless Internet Access, Wireless Internet Services, Wireless Internet Providers and more. Wireless Internet is affiliated with Configuring Wireless Networks.

Why and when would you want to install a wireless adhoc network? Well you would want to install a wireless Ad HoC network when you do not have the equipment for a wired network; you lack a wireless router and want to share an internet connection, or a temporary meeting place where you need to share information.

The first type of set up will be if you do have an internet connection but you lack a wireless access point or a wireless router to share that connection. This could be a very common scenario at a business meeting or during a classroom study session.

First, each computer will need a wireless adapter. Next click the advance tab near the bottom right and click (computer to computer ad-hoc networks only). Second you will need to add your ad-hoc wireless network so click add. Fill in the network name (SSID) and choose WEP encryption. You will want to use WEP if are using older adapters and use WPA if you are sure all the computers on the ad-hoc wireless network can handle it. It is not a requirement to use encryption but just remember that anyone will be able to join your network.

Because we will want everyone to share our wired Ethernet connection you will need to enable ICS (Internet Connection Sharing) on the wired network adapter not the wireless adapter. This seems like common sense but I have seen many people trying to setup ICS on their wireless adapter. Just go to your network connections and right click the Ethernet connections and press the advanced tab. Check the box that says enable ICS. Once you have setup your ICS, go to every computer and configure their wireless adapter like you did the first one.

ICS will act as a DHCP server and assign private TCP/IP address to your ad-wireless network clients. Each computer will receive a TCP/IP address from 192.168.0.1 to 192.168.0.254. ICS will also tell the computers on the network the location of their default gateway which is the computer you set up ICS on.

Trouble shooting a wireless ad-hoc network can be a head ache. Make sure you set up the ICS computer and one client computer. You will want to check to make sure that the first client computer has the correct IP address so type CMD into the run box to bring up the command line. Next, type in ipconfig, you should see a number of 192.168.0.2 or something similar. Next type ping 192.168.0.1 or the number of your default gateway. If you can ping it you should see four reply messages.

Once you have the first two computers connected correctly, just go to all the other computers and configure the wireless adapters the same way. Other common mistakes are: leaving the firewalls on, wrong encryption and just general typos.

In my next article I will describe how to set up a wireless ad-hoc network with-out a wired LAN internet connection.

1. Essential Equipment

Right, let’s move right along. The first thing to do in setting up a wireless home network is to get the correct equipment. These are the things you need:

Wireless home networking kit

This is your basic equipment for the network. Typically, these home networking kits come with a firewalled wireless router (e.g. the immensely popular Linksys WRT54G). Some also bundle a wireless PC card for connecting laptops to the network, or a wireless USB adapter for connecting desktop PCs.

Windows installation CDs

These are required sometimes during installation of drivers, so its handy to have them around first.

Ethernet cables

These are required if you intend to mix wired PCs into a wireless network. For example, you can connect an Ethernet cable between the wireless router and a desktop PC.

2. Install the Wireless Router

Install the wireless router according to the manufacturer’s instructions. Modern wireless home networking kits make this really easy. Just connect the wireless router to power supply, connect the wireless PC card to your laptop, or USB adapter (or Ethernet cable) to the desktop PC. Then insert the installation CD into one PC and start the software installation process.

As part of the setup process, you usually need to surf to a local IP address, e.g. 192.168.0.1 to setup basic parameters for the router. Most of the options can be left as default, with the exception of SSID (Service Set Identifier) and encryption settings, which are explained below.

3. Choose the Service Set Identifier

Wireless networks require a network identification code called the Service Set Identifier (SSID). When connecting devices to the network, this is the name you use to specify which network you’re connecting to. Make sure you set up this parameter using the router setup page or utility.

4. Encrypt Your Wireless Network

Remember an intruder can easily gain access to an unencrypted network without too much trouble. Wireless networks these days usually use the WEP standard to set up encryption. To configure this, go to your router setup page or utility and enter the WEP security key (usually its a 128 bit hexdecimal text entry you need to key in).

Note this WEP key down. Now, go to each PC in your network. Open up the Control Panel -> Network Connections and select your wireless network connection. You need to enter the WEP key for the connection - the manufacturer’s should have instructions on how to do this.

5. Sharing the Printer

If you intend to share a printer (say from your desktop), then go to your desktop, go to Control Panel and select Printers. Right-click your printer icon, and choose Properties. If there’s a Shared tab in the dialog box that appears, click the tab and make sure the share option is selected.

Conclusion

Guess what? That’s it! Setting up a wireless network is as simple as that. You can now easily check email, share files, or print documents from the comfort of your living room, garage or front porch! So what are you waiting for? Get busy and set up that wireless network now!

Are you tired of laying wires through your house, creeping through small places just to get the right sound effect? Wireless speakers are the answer to your headaches. With wireless speakers you gain the freedom to move your music to where you want it to be without the hassles of cables. Planning to have a party outside? Don’t move your whole entertainment system outside while you can make use of outdoor wireless speakers which can move right along with the party.

Want to have hi-fi quality sound through your laptop computer? Why should you be tied to wires while using a portable computer? Make use of wireless speakers to give you the freedom to work or play on your computer where you want to, while having the high fidelity sound you deserve.
Here are a few examples of how you can use wireless speakers to improve your way of living.

Listen to your favorite music collection while taking a bath.

Have a BBQ or party outside without having to move your whole stereo system.

You can store all your favorite music on your computer and listen to it anywhere in your home.

Listen to music while working in the garden.

When your computer is doing certain time consuming tasks, have it play a sound when it is done with the task or when there is an error and have your wireless speaker notify you while you are lying next to the pool.

Get the perfect surround sound effect by having the freedom to move the speakers to exactly the right spots without getting tangled in wires.

Let your computer notify you of upcoming tasks or appointments by playing a sound through your outdoor wireless speakers, while you are washing your car.

Let your wireless speaker notify you discretely of intruders by connecting it to your alarm system.

Use you wireless speakers as a portable intercom system.

There are however a few things you need to watch out for when shopping for wireless speakers. Some are listed here:

Interference

Some wireless speakers may interfere with other wireless devices in your house like cordless phones. A good wireless speaker system will allow you to tune it to a different frequency to overcome these interferences.

Battery life

Battery life is not always too great on wireless speakers, as it consumes power to drive the speakers, internal amplifier and RF receiver. So, if you want to use your wireless speakers for extended periods of time, it may be wise to make use of the AC power adaptor. Now this may not always be practical - the whole idea of wireless speakers is to get rid of the wires. Rechargeable batteries might be the answer and some of the models even come with rechargeable batteries -something to consider when you need total freedom, even from power outlets.

Range

Most wireless speakers can work fine within a range of 150 to 300 feet from the transmitter. (Which would be located at the source of sound i.e. your hi-fi or computer) The RF frequency is high enough for it to work through walls and furniture. You do not need a line of sight, but bear in mind that obstacles weakens the signal, and the more obstacles between the transmitter and receiver, the shorter the range will become.

Weatherproof

Outdoor wireless speakers are claimed to be weatherproof, but if you do not need to use your speakers outside all the time, rather store them inside. This will definitely extend the life of your valuable outdoor wireless speakers. If you really need to leave it outside all the time, try to find a spot where it can be hidden from the most harsh weather conditions.

Stereo

Not all wireless speaker systems include two speakers to give you a stereo experience. Especially the outdoor wireless speakers are sold as single units. This can easily be overcome by purchasing two speakers, obviously doubling the price.

Legislation

Wireless speakers use RF signals which may interfere with other RF devices. Make sure that the frequency range is legal in your country. If it is sold by a reputable dealer in your country, this should not be a problem.
Wireless speakers are till a fairly new technology and some still have issues to be sorted out. So you have to do your shopping wisely.

Installing a PCI wireless card might seem like a bit of an adventure — after all, you have to open the case, find where to put the thing, close it again… and then you have to deal with the software! Even if you’ve never opened your computer before, though, you shouldn’t have too much trouble with it if you follow this simple 10 step guide.

Step 1: Look at the Manual. Yes, I know it seems like a dull thing to do, but you really need to at least skim the manual for things if you’re going to go putting them in your computer. It’s much better to do it now than to realise afterwards that you missed an essential step in the installation. A few cards, for example, require you to install the software before installing the card — do this now if you need to.

Step 2: Switch the Computer Off. Before you even think about opening the computer, you’ve got to switch it off. You should use the ‘Shut Down’ option to make sure that the computer will start fresh next time, and wait for it to shut down completely.

Step 3: Unplug the Computer. To be safe, you should disconnect the computer from the power supply now. If there is anything connected to the computer, you should unplug that from the power too, as well as unplugging the wires from the back of the computer. If you’re nervous that you won’t remember which wire goes where when it’s time to put them back again, you could draw a diagram before you start this step. Most modern computers have a matching color coding system on the rear panel. Pink goes to pink, green to green etc.

Step 4: Remove the Case. To avoid damaging your computer’s parts or electrocuting yourself, you should be wearing an anti-static wristband (also known as a ground strap) whenever you open your computer. If you’re not sure how to get the case off, consult your computer’s manual. It’s usually just a matter of unscrewing, though — but make sure you keep the screws somewhere where they won’t get lost.

Step 5: When the cover is removed, the first thing to do is to locate the PCI slots on your motherboard, different motherboards have different amounts of PCI slots, for example you may already have a PCI card installed, in which case just choose an empty slot to install your new PCI card. PCI slots are long, rectangular slots inside the computer. Some of the available PCI slots might be used by existing modems or Ethernet cards. If there’s no space for your new wireless card, then you might need to remove some of this old equipment.

Step 6: Insert the PCI Card. If you’re using a PCI slot that hasn’t been used before, you’ll need to unscrew the piece of metal filling the gap in the back of the computer created by there being no card there. Make sure you store this piece in a safe place, in case you ever need it again.

When you insert the PCI card into the slot, do it as carefully as you can. Try not to touch any of the circuits on the card. Once it’s in the slot, you will need to press firmly, but don’t use too much force. You should also make sure that you point the wireless card’s antenna upwards.

Step 7: Close the Case. Just do what you did in step 4 in reverse — put it all back together.

Step 8: Plug In and Start. You need to plug your computer back in and start it. If you don’t want to re-attach all your cables right now, you will at least need to plug in the keyboard, mouse and monitor. Many people are scared when they turn on their computer again after installing a PCI card and it doesn’t work — only to find that the error was caused by them not reconnecting their keyboard! When you reboot your machine Windows (or other OS) should find the card automatically, it will then prompt you for the driver disk/cd that came with your card, insert the CD and follow the on-screen instructions.

Step 9: Install Drivers and Software. Once the computer’s done starting, it should notice it has some new hardware. This is when you should insert the CD that came with the card, and leave Windows to do its thing. If everything’s gone to plan, the PCI card should be set up automatically. If things don’t happen automatically, try inserting the CD before you panic.

Step 10: Configure Your Network. Your PCI wireless card gives your computer a permanent wireless connection. The first time you use it, you should be asked which wireless network you want to connect to. Choose your wireless network from the list, and you’re ready to go!

It appears we need to further streamline health care and HIPPA now in effect is quite a nightmare trying to comply with and implement without making a mistake and possibly being sued as the trial lawyers testing the law. The Malpractice insurance rates may go up again. On one hand you have the ‘know your customer” laws and on the other you have “privacy rules.”

Usually when new laws and regulations come along they are never welcomed, they cause costs to go up, cause chaos and some smart entrepreneur comes along and solves the problems, we have seen this in Aviation, Communication, Trucking, Auto Industry, Mining, Marine, Construction, Education and let’s face it, we have seen it in all sectors. The new regulation is no matter how well intended always a problem. These rules when enforced by mandate rather than implementation by free market pressures and desires of patrons tend to cause the worst problems as, they inevitably are prostituted by greed, back door deals and controlled whiners of a system. The whiners think they are to attain justice, but usually end up causing a worse problem upon themselves and the whole of the users of the system.

Today we have a chance to computerize the HIPPA issue and recently I had discussed this at length with the IT Think Tank President in Omaha, NE. They had a plan, which would take the PDA Wireless Device and put all the information, which would be available in the ambulance and to first responders.

It appears that there are several entrepreneurs and larger Software and IT people who specialize Medical issues. One project with a major player in the legal field is PocketMD (.com). The World Think Tank had asked about a mobile HIPPA solution for first responders and they have built in accommodations for privacy, particularly with the triple DES encryption. So the data is secured. This mobile application can also work in the battle space arena for quick response to personal and the data set will be two-way so it can give data on the patient and run the data and send back an answer. So this could be used for casualties or those nearby who happen to be in the wrong place at the wrong time.

The Nebraska IT Think Tank is looking into the “huge data base” application for the PDA. This would be a relational database (similar to a rubics cube) in which the PDA could make queries for medical information. Access to this information would be “compartmentalized” based on the hospital, physician, or other source of inquiry. This information would be well secured and protected. The whole project would run on an “ASP Model” - application service provider - that charges based on the type of access, amount of data transferred, etc. - a type of subscription model. They are also looking into “medical smart cards” with the PDA - one of the companies in Omaha has made some great products in that area. Privacy, insurance companies and ethics are all worked out by defining the “business rules” for access to the database.

There are several other areas of potential affiliation; dictation, charge capture, and medical reference database content. The wireless system is working on 802.11 - which does not have a very long range. There are specialized PDAs that come with different radio freq and capabilities. They had mentioned to me “I am like you - intrigued by the possible military apps - especially field services - procurement, targeting, etc.” So far, the VA Hospitals have been the best opportunity for this test market so this will happen. They hope to have a private hospital pay for implementation soon. They are even working on one “user group” as a conduit for development - if the user group provides access to their members, we would provide a subscription plan for the software and equipment customized to their requirements - saving PocketMD marketing costs and saving the user group members a lot of money in the process.

President George W. Bush had made an interesting and unusual comment about this, unusual because no one realized he was so up on all this stuff. He said that streamlining these things, issues with HIPPA and Healthcare could be done through IT. Absolutely in our opinion, as long as everyone can agree on a standardized system like we discussed above, where everyone is on the same page. In our opinion PocketMD has developed the most robust software for use by physicians in a hospital. They have more features and better security than any on the market, yet there is a risk of becoming the “Betamax” in the “VCR” race. Companies such as MercuryMD and PatientKeeper simply have more marketing dollars. But either way I bet we find a way to take care of this HIPPA issue that everyone is on edge about sense the lawyers are lining up to sue and the HMOs and Private Hospitals are re-doing their entire method of doing business. The investors of PocketMD(PMD) are looking to take MD Tracker public, which for the medical industry looks like an interesting prospect.

PocketMD:

MercuryMD;

PatientKeeper;

http://www.patientkeeper.com/

MD Tracker;

There are many start-ups out there and now the investment bankers have stepped in and the free market system should fix it. VC is lining up to spend on these to fix the problem. There will be ROI expected from those who solve this problem and that will still slightly raise prices for health care and there will be some systems with issues, feature creep during programming and implementation costs and some failures. Some lawsuits, but in the end although the problems will be quite burdensome and much will be fought by the employees who do not like it as with any new system, innovation or change due to resistance of the status quo.

In the trucking industry they have mobile technologies we have been studying are mobile and work off data bases in the dispatch office. These similar systems with real time data, Video Cell Phones could save lives, monitor school buses, Rapid Transit Districts, Bus Stops, Airliners when used in connection with WiFi in the sky and passenger trains, trolley cars and trams.

The systems are so powerful and robust that it appears with such a system it could be placed on telephone poles and catch bad guys, which drove down a street in a Ryder rental truck with bomb material odors. They could be set up with sensors which could be triggered by infrared and could detect illegal migration, troop movement into areas, stick it on top of a Socorro cactus. Great for plant security, hook it to a sound non-lethal fire mechanism up the road 500 yards, and take out bad guys with remote button and/or force them to run back where they came from or risk burst ear drums and brain damage? These units could be put them on Sarge units from Sandia to patrol borders, infrastructures, military bases, important buildings and plants. Put them on UAVs, ATVs, UUVs and all kinds of stuff, even organic birds to track migration and give real time data.

But back to the IT solutions for HIPPA, yes in fact this is absolutely the way to fix this potentially disastrous problem caused by more regulations in the health care industry when they probably just need tort reform and less law suits and reality based systems with ethical people working in them. The problem is that the over all issues with ethics in America has permeated every part of civilization, so it should not be too surprising that up until now your medical records may have been available to more people than you might have wanted.

In the end HIPPA is here to stay and is a noble calling for privacy, even if there may have been other free market solutions to stop the data leak for privacy issues. This implementation is occurring and the entrepreneurs are solving the problem with their belief that anything worth doing is worth doing for a profit.

HIPPA is no doubt the greatest controversy other than the need for tort reform in Health Care Industry since the turn of the millennium. IT will assist in streamlining the internal systems, which are now dealing with the new HIPPA regulations, but it will take time to implement and ramp up. In the end patients will be happy to know their privacy is protected, even when it travels thru the wireless airwaves to mobile hand held devices.

Setting up a wireless router is easy. Essentially you turn your cable or DSL modem off and your wireless router on. Then, you connect the router to the modem with a cable, and turn the modem back on. You are more or less done. The wireless network wizard on your computer will pick up the router and, if your ISP does not have any special requirements, away-you-go, you are on the Internet.

For ease of setup and configuration, manufacturers ship wireless routers with all security disabled. Therein lies the problem. If you do not take any further steps to secure your router, and a surprising number of people don’t, your network will be wide open to all passersby and strangers. It’s like you’ve hung out a sign, “The door is open. Please come in and help yourself.”

The problem is not that strangers will be able to use your router to access the Internet but that, without further protection, would-be intruders will be able monitor and sniff out information you send and receive on your network. Malicious intruders can even hop on to your internal network; access your hard drives; and, steal, edit, or delete files on your computer.

The good news is that it is relatively easy to secure your wireless router. Here are three basic steps you should take.

1. Password protect the access to your router’s internal configuration

To access your router’s internal setup, open a browser and enter the routers setup URL. The URL will be specified in the manual. The URLs for D-Link and Linksys routers, two major manufacturers of wireless routers, are http://192.168.0.1 and http://192.168.1.1, respectively.

For Linksys routers, leave the user name blank and type “admin” (without the quotes) in the password field and press enter. To change the password, simply click on the Password tab and enter your new password.

For other routers, please consult your manual. Alternately, you can search on the Internet with the term “default login for “. Don’t be surprised to find quite a number of pages listing default login parameters for many different routers, even uncommon ones.

2. Change the default SSID (Service Set IDentifier)

The SSID is the name of a WLAN (Wireless Local Area Network). All wireless devices on a WLAN use SSIDs to communicate with each other.

Routers ship with standard default SSIDs. For example, the default SSID for Linksys routers is, not unsurprisingly, “Linksys”. As you can see, if you don’t change the default SSID of your router a would-be intruder armed with a few common SSIDs from major manufacturers will be able to find your wireless network quite easily.

To change the SSID, click on the Wireless tab. Look for an input item labeled SSID. It will be near the top. Enter a new name for network. Don’t use something like “My Network”. Use a name that is be hard to guess.

3. Disable SSID broadcast

Wireless enabled computers use network discovery software to automatically search for nearby SSIDs. Some of the more advanced software will query the SSIDs of nearby networks and even display their names. Therefore, changing the network name only helps partially to secure your network. To prevent your network name from being discovered, you must disable SSID broadcast.

In the same screen that you changed the name of your network, you will see options for SSID broadcast. Choose “Disable SSID” to make your network invisible. Now save all your settings and log out.

Since your wireless network is now invisible, you will have to configure your computers to connect to your wireless network using the new name. On Windows XP, start by clicking on the wireless icon in the Notification Area and proceed from there.

With these three steps, your network now has basic security. However, if you keep sensitive information on your computers, you may want to secure your wireless network even further. For example, you can

• Change the channel your router uses to transmit and receive data on a regularly basis.
• Restrict devices that can connect to the router by filtering out MAC (Media Access Control) addresses.
• Use encryption such as WEP and WPA.

As with most things in life, security is a trade off between cost (time, money, inconvenience) and benefit (ease of use). It is a personal decision you make. However for the majority of home uses, the three basic steps plus WEP/WPA encryption provides reasonably strong security.

Turning on encryption is a two-step process. First you configure your router to use encryption using an encryption key of your choice. And then, you configure your computer to use the encryption key. The actual process of configuring your router for encryption varies from router to router. Please consult the router’s manual.

There are even stronger methods for ensuring security. A strong and robust security method is RADIUS (Remote Authentication Dial In User Service). Using RADIUS requires additional hardware and software. However, there are companies that offer RADIUS security as a subscription based service. The fees are reasonable and dropping.

Therefore for example, if you run a business on your wireless network, have sensitive data on your computers such as credit card information, and have a number of users who access your network, you should consider using RADIUS. Since the service sector for RADIUS is dynamic and growing, a search on the Internet with terms like “RADIUS subscription” or “RADIUS service” is probably the best way to locate one.
