Set up a home network – Part III

This is Part III of our ongoing series regarding home and small-business networks. You can read the first two installments here:  Part I and Part II.

In Part II, we discussed how to use a 'wired' system with Ethernet cabling to connect your computers and broadband connection. We suggested that you purchase a Wireless Cable/DSL Router with 4 port switch to connect your computers. The reason we suggested a wireless router is two fold; 1) The cost is only a few bucks more, and 2) Having the wireless gives you the ability to easily add a laptop or computer in another room to your network.

Typically, wireless routers can broadcast a signal that will reach around 75' indoors. However, that number reduces significantly depending on the barriers it has to pass through…walls, ceilings, type of walls and floors, etc. For best results, I like to keep the wireless computer as close to line of sight as possible to the router (least number of walls and barriers like furniture). Currently, the standard used in wireless computing (wi-fi) is 802.11g. For those with inquisitive minds, you can get detailed definitions of all terms wireless at Webopedia. This link is a comprehensive list of wireless networking terms. 

As with the wired setup, use the CD that came with your brand of router to walk through the setup. The first thing you want to do is assign a new password (right it down and remember it for future use) for the routers settings. Most of the wizards offer you the chance to do this right away.

Next, you want to setup the wireless security for your system. Enabling wireless security drastically reduces the chances of a hacker trying to break into your network. The first step you will be asked to do is assign a name (SSID – Service Set Identifier) to your network. Don't use your name…use something like your street name or high school mascot or development name…etc. Again, right this down and don't forget it. You will also be given the opportunity to broadcast your wireless name or not…for ultimate security, click "No" on the broadcast option. However, for ease of setup, as long as you are following the rest of the security steps, broadcasting should be ok.

Broadcasting your wireless names allows computers with a wireless network card to see what networks are available. If you are broadcasting you need to be secure.

Set up a home network – Part II

Last week we introduced you to some networking terms and technologies. This week, we will show you how to start building your network.

In these instructions we discuss how to setup a network for sharing the Internet, but if you only want to setup a network for sharing files and printers without broadband, simply leave out the broadband modem and these instructions will still apply. 

One term we did not define last week was Network Interface Card (NIC). Currently, there are two main types of NIC's. Wireless and wired. A NIC is a device that is connected to your computer that allows communication with other computers (networking). This can be done either through wireless means or wired means with an ethernet cable.

All computers that you want to network need to have a NIC. You choose whether it is wireless or wired. Almost all computers built since 2002 have an internal NIC for networking right from the factory…even laptops. Almost all laptops built since 2004 have built-in wireless networking capabilities as well. If you need to add one to your computer, a NIC will cost between $10-25. A wireless NIC will cost around $40.

Open Office – The FREE Office Alternative

Microsoft Office has dominated the office space (spreadsheet, word processor, presentation creation, etc). Over the recent few years, Open Office has made huge strides. Backed by Sun Microsystems and now Google as well among others, this suite of office products is poised to take off.

Open Office includes a word processor, spreadsheet, presentation manager, database program, and graphics program.
 
The download is huge and can take up to seven hours with dial-up Internet…so don’t attempt it unless you have a fast connection or a lot of time.

What should I back up?

Recently, you have heard me talk a great deal about flash memory drives and there usefulness for backup. One of our listeners/newsletter readers, recently asked what files are important to backup.

So, tip number one in backup is to backup only those files that you create. These include but are not limited to:

  • Financial program data (Quicken, Money, etc) 
  • Email and other address books 
  • Saved email messages
  • Important word processing documents, spreadsheets and/or databases you have created 
  • Calendar/appointment information 
  • Digital pictures (from digital cameras AND scanners) 
  • Internet favorites or bookmarks 
  • Genealogy research 
  • Downloaded programs or utilities (backup the original installation file) 

You get the picture. Anything important to you that you have created and don’t want to lose, should be backed up.

Programs (with the exception of downloaded programs as noted above), do not need to be backed up because you can rebuild them with original installation CD’s and disks.

For even more information about backup use our site search engine to search for backup for even more specifics about backing up your important data.

Simple Advice to Protect Your Computer and Your Sanity

This tip, if followed, could substantially limit the number of phone calls we get on the radio show and put a dent in my computer troubleshooting and training business. I can sum up the entire tip in one phrase you have heard me utter many times on the radio show:

"If it ain’t broke, don’t fix it."

 

I know ain’t isn’t a word, but if AOL can say "You’ve got mail", please allow me a little latitude.

Computers present the largest potential money and time pit ever created. Because the computer age is still very much in its infancy, the myriad of new upgrades and gadgets make it difficult too leave our machines alone. My advice to computer users every where is to take a step back and look at what you do with your computer, what you would like to do and how does it all fit.

Keep an eye on the kids

One common question I get from parents is how to keep kids safe while using the Internet.  Here are some apps and sites to help answer questions about kids and the Internet:

However, if you use Internet Explorer, then you have a great tool already built into the browser itself.  Here’s how to use it:

  1. Click on Start
  2. Click on Settings
  3. Click on Control Panel
  4. Double Click on Internet Options (or Internet)
  5. Click on the Content tab
  6. Click on the Enable button next to the "Content Advisor"
  7. Use the tools provided to restrict access to web sites that you approve (make sure that you remember and protect the password you set for this feature)

Give this tool a try and I think you will find it useful.

How to Format Your Hard Drive and Reinstall Windows

WARNING:  I have done my best to outline the steps in this somewhat arduous task, but undertake this procedure at your own risk. Because of the vast differences in hardware and software, I cannot possibly cover every nuance. Please use this Tip as a guide and not the end all. AND BE SURE TO BACKUP ANYTHING YOU DON"T WANT TO LOSE PRIOR TO UNDERTAKING THE TASK!

Since many of the sites that I used to refer listeners to regarding this subject have either disappeared or no longer have the information, I am starting a multi-part tip outlining the steps to reformat your computer. In this week’s tip, I’ll explain the what, why’s, and when’s?

What does it mean ‘format my hard drive’? Formatting a hard drive erases all current information (for all practical purposes) and let’s your computer start with a clean slate. Formatting deletes all applications AND data from your computer. The process itself requires very little technical know how. What comes after the format involves the techy knowledge.

Why would I need to format my hard drive? If your computer uses Windows 95/98 or Me, I recommend formatting and reinstalling Windows at least every two years as a maintenance routine. Performing this routine purges your computer of any little errors and irritations that have cropped up and thus makes your computer feel and run like ‘new’ again. You also would need to format and reinstall if you have encountered innumerable error messages or encounter a runaway virus.

When should you perform this purging and restoration of your computer? I answered that question along with the ‘why’ above….at least every two years for any Windows version but Windows XP. Windows XP appeared almost two and a half years ago and has proved to be quite stable and resilient so I’m reserving judgment as to how often it should be done for XP.

If you use a name brand computer like HP, Compaq, E-Machines or even some Gateway systems, they come with a disk or disk set (on CD’s) called "Restore Disks". These disks make the process very easy. Put the disk in, shut your computer off, turn it back on and follow the on-screen instructions. REMEMBER, this will erase all data on your computer, so backup anything you don’t want to lose.

WARNING! Your Internet connection is not optimized!

Banner ads are a real and somewhat necessary part of our Internet world. You see banner ads at the top of nearly every Web site you visit. 

In the past year, one particular ad seems to pop up more frequently than others. It reads something like this:

WARNING! Your Internet connection is not optimized. Click Here to boost your Internet speed!

The ad cleverly (some people say deceptively) resembles a Window’s warning box and thus looks legit. However, the warning is simply an advertisement. 

Don’t fall prey to it. Clicking on the ad will lead you to their web site where you will be asked to lay out $30. If you actually see any gains in speed, they will be negligible and intermittent.

Use the Internet to stop solicitor calls

Two years ago, Colorado became one of the first states to institute a "no-call" list that consumers could sign up for to prevent solicitation phone calls. This past week, the FTC started a national "no-call" list. These lists must be checked by phone solicitation companies every three months to updated their databases. If a solicitor calls you and you are registered on the "no-call" list, you can file a complaint and the solicitor will be fined fairly substantially ( up to $11,000 per incident for the national list).

As opposed to spam (unsolicited email), phone solicitors are regulated and must comply to certain rules. Therefore, these lists do work. Colorado residents who signed up two years ago report that their phone solicitation calls are almost nil. In less than twenty-four hours, the national list had almost one million people sign up. The FTC expects nearly sixty million numbers to be registered by next summer.
