Most people don't know that they already have everything they need to start saving money using internet telephony, or VoIP. All you have to have is a regular telephone and high-speed internet access. That's it! If you have both of those, you are ready to start saving loads of money on local and long distance phone calls.

It is inevitable that VOIP will replace traditional telephone service at some point. The only question is when should you jump in?

VOIP is quickly becoming more reliable and receiving wider acceptance. In fact, phone companies are already taking advantage of the technology to provide cheaper long distance rates. Like any emerging technology, however, there are kinks in the system that are still being worked out.

Advantages:

Internet Phone Service has numerous advantages over traditional telephone service. The most obvious is the cost benefits. If you have a high-speed internet connection, you can make phone calls from PC-to-PC anywhere in the world for FREE! More common PC-to-Phone calls usually come with a small charge but are still much cheaper than regular phone service.

For a small monthly fee, you can sign up with a VoIP service provider and get unlimited calls within the country! International calls can also be made for a fraction of the cost of regular service.

Another advantage is its portability. You can make and receive phone calls wherever there is a broadband connection by simply signing in to your VOIP account. This makes VOIP as convenient as e-mail. When you're traveling, you simply pack a headset or Internet phone; then you can talk to family or colleagues for next to nothing.

Phone-to-phone VOIP is also portable. Internet phones are small and light enough to take anywhere. When you sign up with a VOIP service provider, the Internet phone or adaptor used by that service is assigned a unique number. This 'phone number' remains valid, even if your VOIP service is in Los Angeles and you're connected to the Internet in London. When plugged into a broadband connection, anywhere in the world, you can make and receive calls as though you were at home.

Features like call forwarding, call waiting, voicemail, caller ID and 3way-calling, are included with Internet telephone at no extra charge. While you're talking on the phone, you can send pictures and documents at the same time.

Disadvantages:

Unfortunately, there are a couple of minor drawbacks you may experience. The first is the fact that you would loose service during a power outage and the other is limited emergency calling.

Conventional phone service continues by the current supplied through the phone line during a blackout. This isn't possible with Internet phones. When the power goes, there goes VOIP service. Battery backups and power generators that provide electricity are the current solutions to this problem.

Emergency (911) calls are another concern for many potential customers as well. In the event that you need to call 911 but can't speak or have to leave, your call can be traced when dialed from a traditional phone. However, this is not the case with VoIP. Fortunately, there is currently technology being developed called 'e911' that will make this possible, so this will not be a problem for much longer.

VOIP also has sound quality and reliability problems. Data sent across the Internet usually arrives at its destination scrambled. E-mail and documents can be reassembled in the correct order when it arrives. Voice data also arrives scrambled, but it's more complicated because of the real-time nature of VOIP. Some data packets may have to be dropped when they don't arrive in time, in order to make voice connections with the least delay. This can cause brief silences in the audio stream.

Your internet connection speed and the distance of the call are the two biggest factors in the quality of the call. If you are in a high-traffic area this may also cause some loss in the quality of the conversation. Once again, technology is constantly being improved on and this is becoming less and less of an inconvenience.

While the disadvantages mentioned above currently present minor problems, it is expected that these will be corrected by the year 2008 and VoIP technology will have become the industry standard for telephone communication.

Let's get one thing straight up front: at some time or another, we have all used someone else's wireless connection to check our email, get directions, or find something entertaining during a less than exciting vacation.

With that being said, there are others who abuse the privilege: The college student next door who decides to use your connection to download hi-def porn. The tweenager who has to have that bootleg Miley Cyrus album. A novice hacker who decides it would be fun to use your gateway for some "exploration".

In this article, I will give you a few steps that will help you reclaim your bandwidth, make your network more secure, and give freeloaders the boot.

1. Change the default username and password on your router.

Many security problems start with the fact that most people don't know how to log into their router to start with.

First, you must open up your browser, and type the IP 192.168.0.1 (or 192.168.1.1 for linksys routers).

It will bring up the login screen automatically. All manufacturers have a default password. For example, dlink's default username is "admin" and the password is left blank.

Check your user manual or the underside of your router for your manufacturer's defaults.

Go the administrative or settings tab once you have logged in, and change it to whatever you would like. Change the username to something unrelated to your first or last name. Try to add a password that has at least one number in it.

Don't forget to change the "user" username and password as well. While you cannot change anything while logged in as "user", this can let experienced freeloaders see your settings, and find a backdoor more easily.

2. Change your SSID.

What is an SSID? In layman's terms, it is your router name. The router will usually come defaulted to the name of the manufacturer, and when the SSID is "Belkin54G", it screams "free internet access". Change it to something boring, and unexciting. This is not time to play "Pimp Your SSID". An unusual or exciting name will automatically attract freeloaders. You can usually find this in the "settings" tab as well.

3. Create a WPA Key

This is simply an 8-63 character password that is stored on your router. In order for anyone to access your connection, they must first type in the correct password. To set up your WPA key, log in to your router. Once there, select the "wireless" tab. Then, enable encryption.

If there are two types of WPA, select "WPA-PSK". This is the one intended for home use. Enter the password. Restart the router.

The next time you (or anyone else) tries to access the router, you will be asked for the key. Your computer will save the key for the next time you access the network, and things should go smoothly from there. You are now moderately secure.

4. Turn down the juice.

Your router is automatically configured for the maximum transmission range. This is great if you live in an 1800sq. foot house on an acre of land. If you live in an apartment or townhome, however, most of your neighbors will get strong signal as well. To prevent this, log into your router. Go to the "settings", or "system" tab, and turn down the signal (or transmission) strength to 50 or 75%. This should give you more than enough signal to get access anywhere in your apartment, and keep the guy down the hall from siphoning your bandwidth

5.Enable MAC based filtering.

By combining this step 3, you can create a highly secure home network. This step is for those who don't mind reading the manual, and playing around with the settings a little.

Every wireless card, network card, and modem has what is known as a MAC address. No device has the same MAC address. This is quite possibly the biggest step you can take towards making your network secure.

This is a pretty technical step, so I will refer you to your user's manual for specifics. I will tell you in broad terms what you will have to do.

Make sure that all the computers that you want on your network are on, and connected to your router.

Log in to the router.

Under the "Security" tab, you find a section that will usually be called "Network Filters" or just "Filters".

Select "Filter by MAC Address".

One by one, add the MAC addresses of your wireless(and wired) devices to the table. Most routers will allow you to add up to 20 addresses.

If you can't find your MAC address, click here for a tutorial.

Then select "Allow Access for these PC's".

Save your settings, and let the router reboot.

Your PC's will be able to access the internet as usual, everyone else will be shut out.

This should eliminate casual and intermediate users of the internet from even being allowed access to router login.

If you make a mistake, and lock yourself out, just do a hard reset of your router, and it will go back to the factory defaults.

These are generic instructions, but they hold true for most consumer level routers currently on the market. For more in-depth instruction, always consult the user's manual that came with your router.

Hopefully, this will ease some of your bandwidth woes, and allow you to get the best out of the internet access you are paying for. So kick those freeloaders to the curb, and then make sure they can't get signal.

I'm gonna go download that Miley Cyrus bootleg.
