Welcome To Gerard's Tech Page


1. Choose your wireless equipment

The first step is to make sure that you have the equipment you need. As you're looking for products in stores or on the Internet, you might notice that you can choose equipment that supports three different wireless networking technologies: 802.11a, 802.11b, and 802.11g. We recommend 802.11g, because it offers excellent performance and is compatible with almost everything.


• Broadband Internet connection

• Wireless router

• A computer with built-in wireless networking support or a wireless network adapter

A wireless router

The router converts the signals coming across your Internet connection into a wireless broadcast, sort of like a cordless phone base station. Be sure to get a wireless router, and not a wireless access point.

A wireless network adapter

Network adapters wirelessly connect your computer to your wireless router. If you have a newer computer you may already have wireless capabilities built in. If this is the case, then you will not need a wireless network adapter. If you need to purchase an adapter for a desktop computer, buy a USB wireless network adapter. If you have a laptop, buy a PC card-based network adapter. Make sure that you have one adapter for every computer on your network.

Note: To make setup easy, choose a network adapter made by the same vendor that made your wireless router. For example, if you find a good price on a Linksys router, choose a Linksys network adapter to go with it. To make shopping even easier, buy a bundle, such as those available from D-Link, Netgear, Linksys, Microsoft, and Buffalo. If you have a desktop computer, make sure that you have an available USB port to plug the wireless network adapter into. If you don't have any open USB ports, buy a hub to add additional ports.

2. Connect your wireless router

Since you'll be temporarily disconnected from the Internet, print these instructions before you go any further.

First, locate your cable modem or DSL modem and unplug it to turn it off.

Next, connect your wireless router to your modem. Your modem should stay connected directly to the Internet. Later, after you've hooked everything up, your computer will wirelessly connect to your router, and the router will send communications through your modem to the Internet.

Next, connect your router to your modem:

Note: The instructions below apply to a Linksys wireless router. The ports on your router may be labeled differently, and the images may look different on your router. Check the documentation that came with your equipment for additional assistance.

• If you currently have your computer connected directly to your modem: Unplug the network cable from the back of your computer, and plug it into the port labeled Internet, WAN, or WLAN on the back of your router.

• If you do not currently have a computer connected to the Internet: Plug one end of a network cable (included with your router) into your modem, and plug the other end of the network cable into the Internet, WAN, or WLAN port on your wireless router.

• If you currently have your computer connected to a router: Unplug the network cable connected to the Internet, WAN, or WLAN port from your current router, and plug this end of the cable into the Internet, WAN, or WLAN port on your wireless router. Then, unplug any other network cables, and plug them into the available ports on your wireless router. You no longer need your original router, because your new wireless router replaces it.

Next, plug in and turn on your cable or DSL modem. Wait a few minutes to give it time to connect to the Internet, and then plug in and turn on your wireless router. After a minute, the Internet, WAN, or WLAN light on your wireless router should light up, indicating that it has successfully connected to your modem.

3. Configure your wireless router

Using the network cable that came with your wireless router, you should temporarily connect your computer to one of the open network ports on your wireless router (any port that isn't labeled Internet, WAN, or WLAN). If you need to, turn your computer on. It should automatically connect to your router.

Next, open Internet Explorer and type in the address to configure your router.

You might be prompted for a password. The address and password you use will vary depending on what type of router you have, so refer to the instructions included with your router.

As a quick reference, this table shows the default addresses, usernames, and passwords for some common router manufacturers.

Router Address Username Password 3Com admin admin

D-Link admin

Linksys admin admin

Microsoft Broadband admin admin

Netgear admin password

Internet Explorer will show your router's configuration page. Most of the default settings should be fine, but you should configure three things:

1. Your wireless network name, known as the SSID. This name identifies your network. You should choose something unique that none of your neighbors will be using.

2. Wireless encryption (WEP) or Wi-Fi Protected Access (WPA), which help protect your wireless network. For most routers, you will provide a passphrase that your router uses to generate several keys. Make sure your passphrase is unique and long (you don't need to memorize it).

3. Your administrative password, which controls your wireless network. Just like any other password, it should not be a word that you can find in the dictionary, and it should be a combination of letters, numbers, and symbols. Be sure you can remember this password, because you'll need it if you ever have to change your router's settings.

The exact steps you follow to configure these settings will vary depending on the type of router you have. After each configuration setting, be sure to click Save Settings, Apply, or OK to save your changes.

Now, you should disconnect the network cable from your computer.

4. Connect your computers

If your computer does not have wireless network support built in, plug your network adapter into your USB port, and place the antenna on top of your computer (in the case of a desktop computer), or insert the network adapter into an empty PC card slot (in the case of a laptop). Windows XP will automatically detect the new adapter, and may prompt you to insert the CD that came with your adapter. The on-screen instructions will guide you through the configuration process.

Note: The steps below only apply if you're using Windows XP Service Pack 2. If you're running Windows XP and you don't have Service Pack 2 yet, plug your computer into your wireless router and download and install Windows XP Service Pack 2.

Windows XP should show an icon with a notification that says it has found a wireless network.

Follow these steps to connect your computer to your wireless network:

1. Right-click the wireless network icon in the lower-right corner of your screen, and then click View Available Wireless Networks. If you run into any problems, consult the documentation that came with your network adapter. Don't be afraid to call their tech support.

2. The Wireless Network Connection window should appear and you should see your wireless network listed with the network name you chose. If you don't see your network, click Refresh network list in the upper-left corner. Click your network, and then click Connect in the lower-right corner.

3. Windows XP prompts you to enter a key. Type the encryption key that you wrote down earlier in both the Network key and Confirm network key boxes, and then click Connect.

4. Windows XP will show its progress as it connects to your network. After you're connected, you can now close the Wireless Network Connection window. You're done.

Note: If the Wireless Network Connection window continues to show Acquiring Network Address, you may have mistyped the encryption key.

Hi Gerard. I see that you've made an entry to the wiki page….good! Keep going. Anything you need, just let me know. On the theory side: start with basic computer science terms on processor, compiler, debugger, etc. and go from there. On the practice side: download Java and Netbeans to your PC. I'll help you get them setup if you can't. Just write a comment here in this discussion and I'll see it. Best of luck! Chris.

, 2008/07/20 16:05

I v'e downloaded java jdk and netbeans but I need help on setup and a good place to start for code help

, 2008/07/20 21:15

You will first install the Java Development KIT (the “JDK” for short). It contains all the basic tools for writing software. You can get the JDK from Sun's Java Page. Once you download it, run the installer and follow the directions. You will need to set an environment variable which is explained in the written instructions.

Once you can run javac at the command line, then you're ready to install netbeans.

Netbeans 6.1 is available right now. Get the biggest version you can download, or the biggest one you have space for on your hard drive. Once downloaded, just double-click the installer and follow the prompts.

The best place to start is with the basics. Everyone always starts at the Sun Java Tutorial. Its fantastic and will keep you learning for a year or more (no lie!).

You start from there, and I'll help where I can. Let me know what problems you encounter. Chris

, 2008/07/22 22:35

Thanks Chris Ive install the program the correct way and im reading the tutorial

I understand what jdk is if {im correct jdk is netbeans plugin}

, 2008/07/23 01:25

The JDK is the full-blown version of java. It gives you the ability to create, test, and run java programs. Most people only have the JRE (Java Runtime Environment), which only lets them run java programs. Only software developers need the JDK.

Netbeans is a tool that helps you create and test java programs. Its an extremely feature-rich tool, but there are still ways to add features to it. Those add-on features are called plugins.

Its interesting that Netbeans is a java program itself. So in effect, you're using java to help create more java. :-)

, 2008/07/28 23:32

Dear Chris

I understand what a compiler is its a computer progam that translate texts written into computer language

I just run a successfull helloworld program in Netbeans

, 2008/07/31 16:14

Congrats! That's a pretty important step. So now you have the JDK and NetBeans installed…great! Are you following the Java Tutorial? Its fantastic reading. (Hard to believe that its free). Keep going and let me know where I can help.

Two helpful notes:

1. Keep notes on your wiki as you go along. You can put your notes on separate pages if you like. You do that by creating a hyperlink to a page that doesn't exist, like this:

See my Hello World example [[HelloWorldExample|here]].  

Then you click on it. The wiki will prompt you to create a new page and then you just start typing. Very useful way to build a collection of documents.

2. You can insert java code into your wiki page and make the wiki colorize it for you. I do that in my wiki here. This is how you do it:

<code java>
..your code goes here

Let me know how I can help

Also…forgot to mention that you can 'subscribe' to this page. By doing that, you'll get an email each time the page is changed. Click on the “Subscribe Page Changes” link or the “Subscribe Namespace Changes” link at the bottom of the page. (FYI: I changed the visual theme of the wiki–these links used to be on the left margin).

, 2008/08/28 16:33

page looks nice. my computer had a virus for 3 weeks. Ive been study wikipedia and java tutorial its very excited for me and it keeps me on a great track and for study and learning im currently work on a mylib,myapp,application in netbeans

, 2008/08/28 20:59

Gerard, great to hear about your progress. I hope you are learning about data types. There are two classes of them: the built-in types, and objects. There are 8 built-in types: boolean, char, byte, short, int, long, float, and double.

  • boolean = a single true/false value. Sometimes we call it a 'flag' because its either on or off
  • char = a single character–any key on your keyboard (plus more 1) ).
  • byte short, int, and long = the integral data types (i.e. numbers with no decimal places)
  • float and double = the real number types (i.e. numbers with decimals)

We can talk about objects later. Objects are composed of different combinations of these 8 basic types.

1) more about that later

Dear Chris When i tried to run my libb app my computer says unable to find java virtual machine.

, 2008/09/26 22:47

Hi Gerard. One thing you'll learn about computer science is that you need to be verbally clear in you writings. You said “my computer” is unable to find the JVM. Does that mean you are working from a command prompt, typed “java”, and got an error? Or are you inside a tool like Netbeans and hit “run” from a menu or button? It makes a difference.

I'll assume you are at the command line since that is where most good learning happens. :-) So you typed java and got an error. What that means is the directory where java resides isn't on your system path. You need to open the Windows System properties panel(Start–>Control Panel–>System). Once there, click the Advanced tab, then the Environment Variables button. You'll see two sets of variables in a new window: one for system variables and one for your user ID. Either one can have an entry called PATH. You need to inspect that and make sure it contains an entry for your java/bin directory. Sun has instructions for this on their site. Its also included in the setup instructions for java.

Once you've done that and saved your changes, close and re-open your command prompt and type set and hit enter. You should see a PATH entry and it should contain the entry you just added. And if it doesn' you'll be able to type java and get the result you expect.

Let me know if this helps.

, 2008/10/02 09:56

Chris I was inside netbeans and i hit the run button to launch my appilcation and thats when that error occured.

My user PATH variables value says C:\Sun\AppServer\bin;C\Sun\SDK\bin is that correct

, 2008/10/07 16:02

Gerard, nevermind my comment above if you were inside of Netbeans. Try this: in Netbeans, goto Tools–>Java Platforms, and the Platform Manager will appear. This is the window where you specify the location of your JVM. Its possible to have more than one JVM on your machine, so you define them here, then use them when you run your projects.

Make sure the one you are using (probably called ”(Default)” ) is here. The classes list should not be empty. If it is, just click the Add Platform button, and follow the instructions.

Then, when you run your program, make sure it is using the working plaform. FYI: This is how you can test your program in multiple versions of java very easily.

Thanks. Chris can we meet again some where in november or december or january

, 2008/10/30 18:00

Gerard, yes we can meet. My schedule changes a lot, so we will have to play it by ear. I can normally get out for lunch, if that suits you. I'll buy…I just can't travel very far. I work near I-95 and Baymeadows Road.

, 2008/11/09 11:20

its kind of the holiday season. Chris lets say somewhere in january

, 2009/01/03 08:27

Chris can we meet friday jan 16 at 1:00pm can you send me the address location or the link location on google maps of the destination where you like to meet. my address is (zip code-32208) 77 andress street Jacksonville Florida

, 2009/03/06 23:04

Dear Chris

I've got a new desktop computer in my room with windows xp for my operating system. i would like to use the same internet service.from my family desktop computer to my new desktop computer what i need to do.

, 2009/03/10 10:24

Hey Gerard. The simplest thing to do is buy a cheap router and a couple of cables. Look in CompUSA, BestBuy, WalMart, etc. You plug your cable modem (or DSL modem etc.) into the router, then both machines plugin to the router. Last step is to configure the router then you're off and running.

, 2009/03/10 10:25

FYI: the editor on my wiki is having issues right now. To restore your page, goto the “old revisions” tab, click on the previous version, and edit that and save.

, 2009/03/18 08:33

Gerard–Sorry for being out of communication for a while. My work and personal schedules have been really busy for the last month or more. I've resolved the issues with my wiki editor–I think you'll like the changes when you edit. :-) Oh and I've restored the last version of your page that had any content. TTYL.

, 2009/03/23 22:32

its ok. I love the track you put me on its a great track I love programming and learning new stuff everyday about programming.

, 2009/03/23 22:37

Very Cool! So what have you been able to do so far? Sometimes the best thing is to pick a project and go with it. If you do that a few times (even if you don't feel like it), you'll end up with good project experience. Do you want to work out a small project? Maybe something simple, like a note keeper or blog. Let me know if you want to try something like that.

Also–do you want to meet again? You had suggested it before but the timing didn't work out. TTYL–Chris.

, 2009/04/05 08:16

Yes. I would like to meet again say April the 24th.say around 1:00pm or 1:30pm or which ever time convenience for you.

, 2009/04/05 08:16
