When a wireless network is set to ad-hoc mode, the wireless-equipped computers are configured to communicate directly with each other. The ad-hoc wireless network will not communicate with any wired network.
Wireless-G Broadband Router What is Spread Spectrum? Spread Spectrum technology is a wideband radio frequency technique developed by the military for use in reliable, secure, mission-critical communications systems. It is designed to trade off bandwidth efficiency for reliability, integrity, and security.
Wireless-G Broadband Router How do I resolve issues with signal loss? There is no way to know the exact range of your wireless network without testing. Every obstacle placed between the Router and a wireless PC will create signal loss. Lead glass, metal, concrete floors, water and walls will inhibit the signal and reduce range. Start with the Router and your wireless PC in the same room and move it away in small increments to determine the maximum range in your environment.
Wireless-G Broadband Router Appendix B: Wireless Security A Brief Overview Whenever data - in the form of files, emails, or messages - is transmitted over your wireless network, it is open to attacks. Wireless networking is inherently risky because it broadcasts information on radio waves. Just like signals from your cellular or cordless phone can be intercepted, signals from your wireless network can also be compromised. What are the risks inherent in wireless networking? Read on.
Wireless-G Broadband Router But even WEP has its problems. WEP's encryption algorithm is referred to as "simple", which also means "weak", because the technology that scrambles the wireless signal isn't too hard to crack for a persistent hacker. There are five common ways that hackers can break into your network and steal your bandwidth as well as your data. The five attacks are popularly known as: 1. Passive Attacks 2. Jamming Attacks 3. Active Attacks 4. Dictionary-building or Table Attacks 5.
Wireless-G Broadband Router Active Attacks Hackers use Active Attacks for three purposes: 1) stealing data, 2) using your network, and 3) modifying your network so it's easier to hack in the next time. In an Active Attack, the hacker has gained access to all of your network settings (SSID, WEP keys, etc.) and is in your network. Once in your wireless network, the hacker has access to all open resources and transmitted data on the network.
Wireless-G Broadband Router examples below, your implementation and administration of network security measures is the key to maximizing wireless security. No preventative measure will guarantee network security but it will make it more difficult for someone to hack into your network. Often, hackers are looking for an easy target. Making your network less attractive to hackers, by making it harder for them to get in, will make them look elsewhere.
Wireless-G Broadband Router 5) SSID There are a few things you can do to make your SSID more secure: a. Disable Broadcast b. Make it unique c. Change it often Most wireless networking devices will give you the option of broadcasting the SSID. This is a option for convenience, allowing anyone to log into your wireless network. In this case, however, anyone includes hackers. So don't broadcast the SSID. A default SSID is set on your wireless devices by the factory. (The Linksys default SSID is "linksys".
Wireless-G Broadband Router PCs unprotected by a firewall router should at least run firewall software, and all PCs should run up-to-date antiviral software. B. WEP Wired Equivalent Privacy (WEP) is often looked upon as a panacea for wireless security concerns. This is overstating WEP's ability. Again, this can only provide enough security to make a hacker's job more difficult. WEP encryption implementation was not put in place with the 802.11 standard.
Wireless-G Broadband Router The solution, then, is to segment your network up into multiple groups. If your network had 80 users and you used four WEP keys, a hacker would have access to only ¼ of your wireless network resources. In this way, multiple keys reduce your liability. Finally, be sure to change your WEP key regularly, once a week or once a day. Using a "dynamic" WEP key, rather than one that is static, makes it even harder for a hacker to break into your network and steal your resources.
Wireless-G Broadband Router WPA Pre-Shared Key If you do not have a RADIUS server, Select the type of algorithm, TKIP or AES, enter a password in the Pre-Shared key field of 8-32 characters, and enter a Group Key Renewal period time between 0 and 99,999 seconds, which instructs the Router how often it should change the encryption keys. WPA RADIUS WPA used in coordination with a RADIUS server. (This should only be used when a RADIUS server is connected to the Router.
Wireless-G Broadband Router Appendix C: Upgrading Firmware The Access Point's firmware is upgraded through the Web-Utility's Help tab. Follow these instructions: 1. Download the firmware from Linksys's website at www.linksys.com. 2. Click Upgrade Firmware from the Web-Utility's Administration tab, and the Upgrade Firmware screen, shown in Figure C-1, will appear. 3. Enter the location of the firmware's file or click the Browse button to find the file. 4.
Wireless-G Broadband Router Appendix D: Windows Help All wireless products require Microsoft Windows. Windows is the most used operating system in the world and comes with many features that help make networking easier. These features can be accessed through Windows Help and are described in this appendix. TCP/IP Before a computer can communicate with the Access Point, TCP/IP must be enabled. TCP/IP is a set of instructions, or protocol, all PCs follow to communicate over a network.
Wireless-G Broadband Router Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter This section describes how to find the MAC address for your computer’s Ethernet adapter so you can use the MAC filtering and/or MAC address cloning feature of the Router. You can also find the IP address of your computer’s Ethernet adapter. This IP address is used for the Router’s filtering, forwarding, and/or DMZ features.
Wireless-G Broadband Router 3. Write down the Physical Address as shown on your computer screen (Figure C-3); it is the MAC address for your Ethernet adapter. This appears as a series of numbers and letters. The MAC address/Physical Address is what you will use for MAC address cloning or MAC filtering. Note: The MAC address is also called the Physical Address. The example in Figure C-3 shows the Ethernet adapter’s IP address as 192.168.1.100. Your computer may show something different.
