Free Wi-Fi High Speed Internet Access |
It is important to know that free access is unsecured. So, if you are going
to do some online banking or ordering online using a credit card, your personal
information could be compromised.
Most locations that you find that offer free Internet access will not have any
restriction, but there are some that may require one or more of the following:
- You may be required to be a guest at their facility.
- You may be required to make a purchase before receiving a login and password.
- Some may ask some survey questions as part of a login process.
Below, you will find a listing of several businesses and institutions that
typically offer Free Wireless Internet Access.
- Academic Locations:
You may find that in most of the larger institutions, they will control the
Internet access and restrict it to students and staff only. But, there are many
that offer free Internet access with no restrictions.
- Cafes, coffee shops, restaurants:
You will find that many of these locations provide free wireless Internet access
without any restriction. Some may require a purchase in order to obtain a login
and password.

Most of these locations offer free access to their guests only. But, you will
also find many that have no restrictions at all.
- Libraries:
More and more cities are now offering free wireless Internet access to the
public. In some cases, you may need to obtain a library card to gain a login and
password. Also, many public libraries have software in place that restrict
access to questionable sites.

Many of these locations will require a login and password to gain access to
their network.

These locations will require a login and password to gain access to their

WLAN Radio Frequency Range |
The range of a wireless product
cannot be solely controlled by the product itself. There are many variables
that factor in to a wireless products range abilities.
Signal interference can be broken into three main categories:
- Physical interference
such as from walls, through floors and ceilings, and other permanent
fixtures in the vicinity.
- Hidden physical
interference, like from materials in your walls that cause signal
deterioration.
- Electromagnetic
interference which is nothing more than a radio wave interfering with
another radio wave. Such as, a microwave that is in use will interfere
with the signal of another radio wave device.
A typical WLAN can achieve a
range of 500 feet (164 meters) depending on the number of obstacles that it
encounters. If extended coverage is required, you can always use additional
access points to accomplish this.

Avoid SPIM |
SPIM is the instant messaging version of SPAM. If you use AOL Instant Messaging,
MSN Messenger or Yahoo Messenger then you are already familiar with SPIM.
Basically, SPIM is an unwanted instant message that tries to force feed a
product or service to you.
In this tip I will show you how you can avoid receiving these unwanted messages.
In AOL 9.0:
- Click the "More Options" button
- Select "IM Settings"
- Click the "Privacy and Security" tab
- Select the "Allow only people on my buddy list" button
Note: AOL's free AIM software does not have these options.
In MSN Messenger:
- Go to Tools>> Options
- Select Privacy
- Place a checkmark next to the following entry: "Only people on my Allow
List can see my status and send me messages"
In Yahoo Messenger:
- Go to Messenger>> Privacy Options
- Select "Ignore List"
- Place a checkmark next to the following entry: "Ignore anyone who is not
on my Messenger List"

Protect your children while online |
The Internet can be a very dangerous place for young impressionable children out
looking for fun. There are online predators in chat rooms that lay and wait for
unsuspecting kids. Before allowing children to access the Internet, be sure to
have a few rules in place and that they understand the importance of following
these simple rules:
- Never give our your full name, address or phone number to anyone you don't
know.
- Never give out your Internet password to anyone, even if they say they're
from your Internet service.
- Never agree to meet with anyone without first checking with your parents. If
you do agree to meet, make sure that it is in a public place and that your
parents are present.
It is increasingly important to ensure that your kids are surfing safely as the
rise in Internet crimes becomes more and more common. There are several programs
that can help with this, however, parental supervision is the most important
tool for keeping children out of dangerous situations online.
A couple of programs to look at are:
<>iProtectYou Pro Web Filter v7.07 is an Internet filtering and Parental control
software program that allows parents, schools and libraries to protect children
from harmful information on the Internet.

<>CyberPatrol's Internet safety software lets you take control of your Internet
access ...even when you can't be there!

Buying a Desktop or a Laptop? |
I often get asked what is best to buy, a desktop or a laptop computer? There are
things that you need to consider when deciding on this. I have outlined a few of
these below:
- Are you looking for a more mobile solution? Are you going to be carrying
your computer around the house and using it at different locations? Do you
travel a lot and have a need for a mobile computer? Do you go on frequent business trips where a laptop computer
would be handy to have? If you answered yes to any of these questions above,
then you will be better off with a laptop computer.
- Laptops will have a better resale value than desktop computers.
- If your don't really have a need for mobility, but space is a definite
consideration, then you can always buy a slim-line desktop computer.
- You will get more functionality with a desktop computer for the same
price as a laptop.
- If you work heavily with graphics programs or action games, you may
enjoy the screen resolution and better functionality of a desktop computer.
- If you are looking for a computer that you can upgrade in the future,
then you will need a desktop computer.
- If you work on a computer for extended periods of time, you may want a
desktop computer for the larger screen size available, better screen
resolution and larger keyboard.
- If your laptop is out of warranty, keep in mind that laptop repairs can
be very costly.

Printing in Notepad |
|
When you copy and paste a document
into Notepad for printing, you do have some control over the print settings.
Here is what you can do:
Go to File>> Page Setup. Under the 'Paper' category you can select the paper
size that you are working with along with the paper source you would like to
print from.
While still in the Page Setup
window and in the Header and Footer text boxes, you will find syntax that will
make Notepad do different things, such as:
- &f - shows the file name or
"Untitled" if it doesn't have one
- &d - displays the date
- &t - inserts the time
according to your computer's clock
- &p - shows the page number
Notepad allows for the use of
more than one combination in the header and footer text boxes.
- && - puts in an ampersand
(&)
- &l (for left)
- &c (for center)
- &r (for right) will align
the header or footer.
In order to use the syntax this
way, just place the code one after the other leaving a space in between. As an
example: &l &d &r &p will align the date left and the page number right.
You can also put in your own text in the header or footer such as; "5 Star
Support" in the Header text area will make Notepad print all future documents
with 5 Star Support as the header.
