Computer Tips: How to protect your wireless network

Having a Wireless networks are a great way to share files, printers, and your Internet connection to any computer in your home. With the use of wireless network adapter installed on your portable computer, you are no longer tied to your desk and have the mobility to use your computer anywhere. You can communicate with friends, read the news, and surf the Web anywhere you can receive a wireless network signal. See steps on How Setup Your Home Wireless Network.

But there are some risks. Since Wireless networks don't stop at the walls of your home. Yes, In fact, it often extend more than 300 feet from your wireless router considering some of new technologies nowadays. If you are living in an apartment, dorm, or condominium, you may have dozens of neighbors who can access your wireless network. If you live in a house, your neighbors and even people on the street or the house across the street can may be able to connect to your network.

Here are the common implications why you should consider reading this article on "Computer Tips: How to protect your wireless network"

1. Slowdown your Internet performance. Imagine you are just checking a website and and the other one on the network is downloading movies and other stuffs. It divides your bandwidth or in simple terms your Internet connection speed. A website that would load in instant will we loading for 30 seconds or more. Thats not good, right? Not to consider when you are opening more than one web pages.

2. Others can Share and access computers and spread dangerous software. Since other can access your network it is also possible that they can also access your shared files and could infect your computer also with virus and spywares. Other can also Monitor the Web sites you visit, read your e-mail and instant messages as they travel across the network, and copy your usernames and passwords. Send spam or perform illegal activities with your Internet connection.

How to protect your wireless network

Protecting your Network is like protecting your self from theft and other outside threats. You can protect your wireless network by using the same method banks use to protect your password when you log on to their Web sites: encryption. Yes, Encryption scrambles data on your wireless network so that only computers that have the encryption key can read your communications.

Here are some wireless encryption:

64-bit WEP (Wired Equivalent Protection). This is the original wireless encryption standard, it is now outdated. The main problem with it is that it can be easily "cracked." Cracking a wireless network means defeating the encryption so that you can establish a connection without being invited.

128-bit WEP. An updated, more secure version of the original WEP. However, skilled attackers can still crack 128-bit WEP in a few hours or less, giving them access to your network.

WPA-PSK (also known as WPA-Personal). A more secure alternative to WEP, but because it is newer, it is not as widely supported. Microsoft Windows XP with Service Pack 2 supports WPA, so this type of encryption is the best choice if you plan to connect only Windows XP computers to your wireless network. However, if you have wireless devices that don't support WPA, such as media extenders or wireless cameras, you'll have to use WEP on your network instead.

You might also see the security method called "WPA-Enterprise." As the name suggests, this method of network encryption is designed for business use. Setup for WPA-Enterprise is more complex than for other types of encryption, and it requires special network infrastructure.

WPA2. The newest type of wireless encryption, WPA2 provides the highest level of encryption available. WPA2 encryption should be your first choice if your wireless router and all of your wireless computers and devices support it.

Even though one type of encryption may be better than another, any type will dramatically improve your network's security by making you a more difficult target.

Can wireless encryption be "cracked"?

The short answer is, "Yes". Any encryption can be cracked. An individual with knowledge of computers and networking, and who is willing to spend a few hours researching free "hacking" tools, can crack encryption in a few hours (or less). However, most users who want to connect without authorization lack the expertise to crack wireless encryption, even relatively weak 64-bit WEP. In a crowded neighborhood with numerous unprotected networks, anyone looking for a free connection will likely choose the unprotected network rather than spend the time to crack your wireless encryption. Therefore, even WEP encryption offers better protection than not having encryption enabled at all.

Here are some Computer Tips on How to protect your wireless network and Here are some tips to keep your data safe when using wireless networks:

1. If you use WEP encryption, change your encryption key once a month. If someone manages to learn your key, they will be locked out again when you change it.

2. Don't connect to unprotected wireless networks—it's possible for someone to monitor your Internet usage and even record your passwords.

3. If you do connect to an unprotected wireless network, don't visit a Web site that requires a password unless the Web site is encrypted. To find out if it's encrypted, look for a lock symbol in the lower-right corner of your browser.

4. SSL secured Web site icon - That is when you see the pod lock on the lower right hand corner of the web browser.

5. If you use WPA-PSK to encrypt your network, set a long passphrase of at least 20 random characters. Better yet, use the full 63 characters by typing a sentence you can remember—just don't make it something that's easily guessed, like a line from a movie.

Computer Tips: How Setup Your Home Wireless Network

Imagine... sharing your Internet access, files and printers or surf the Web while you're sitting on your couch or in your yard. Isn't that convenient? Well that is the technology of Wireless Network. The good news it's easier to Setup Your Home Wireless Network.

Here are some computer tips on How Setup Your Home Wireless Network:

1.Choose your wireless equipment
- Yes, first comes first. You have to choose your wireless equipment. But when you are shopping for the equipments you need you will notice that there are three different wireless networking technologies:
  • 802.11a - 54 Mbps maximum data rate and has a range of ~35m
  • 802.11b - 11 Mbps maximum data rate and has a range of ~38m
  • 802.11g - 54 Mbps maximum data rate and has a range of ~38m
  • 802.11n - 600 Mbps maximum data rate and has a range of ~70m
I do recommend 802.11g, because it offers excellent performance and is compatible with almost everything. After Choosing the wireless networking technology you will be using, now is the time to shop for the equipment. You may include the following on your shopping list:



  • Wireless Router - It converts the signals coming across your Internet connection into a wireless broadcast. Be sure to get a wireless router and not a wireless access point.


  • Wireless network adapter - It is the one that connects your computer to your wireless router. Most branded computer nowadays specially the notebooks already has a built in so just check your users manual or specs of your computer. If you do not have one you can add a PCI Wireless adapter or a USB wireless adapter on your computer. I would recommend you to get the same brand as your wireless router to avoid conflict.

2.Connect your wireless router
- You may use the diagram below as your as your guide. Printing the instructions below would be much recommended.

a. Connect your router to your modem
  • 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.




b. 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.

Note: Check the documentation that came with your equipment for additional assistance.

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.
  • 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.
  • The table below shows the default addresses, usernames, and passwords for some common router manufacturers

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


  • 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.
  • 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).
  • 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

You should have installed the wireless driver of software of your Wireless Network card or adapter. Usually, it is auto detect and will be prompted to insert the CD that came with your adapter. Please follow the on-screen instructions that will guide you through the configuration process. You should see the wireless Icon on your task bar.



Congratulation you are now ready to to connect your computer to your wireless network.

Here are the steps on how to 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. Choose wireless connection


3. You will be prompt 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. It 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.
