  • Page 66 Wireless-G VPN 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. In other words, more bandwidth is consumed than in the case of narrowband transmission, but the trade-off produces a signal that is, in effect, louder and thus easier to detect, provided that the receiver knows the parameters of the spread-spectrum signal being broadcast.
  • Page 67 How many channels/frequencies are available with the Router? There are eleven available channels, ranging from 1 to 11 (in North America). If your questions are not addressed here, refer to the Linksys website, www.linksys.com. Appendix A: Troubleshooting Frequently Asked Questions...

  • Page 68: Appendix B: Wireless Security

    Wireless-G VPN 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.
  • Page 69 Wireless-G VPN 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.
  • Page 70 Wireless-G VPN 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.
  • Page 71 Wireless-G VPN 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.
  • Page 72 So don't broadcast the SSID. A default SSID is set on your wireless devices by the factory. (The Linksys default SSID is "linksys".) Hackers know these defaults and can check these against your network. Change your SSID to something unique and not something related to your company or the networking products you use.
  • Page 73 Wireless-G VPN Broadband Router not completely secure. One piece of information still not encrypted is the MAC address, which hackers can use to break into a network by spoofing (or faking) the MAC address. Programs exist on the Internet that are designed to defeat WEP. The best known of these is AirSnort. In about a day, AirSnort can analyze enough of the wireless transmissions to crack the WEP key.
  • Page 74 If you wish to use a WEP Passphrase, it can be a maximum of 16 alphanumeric characters. This passphrase may not work with non-Linksys products due to possible incompatibility with other vendors' passphrase generators. The WEP Key can be generated using your Passphrase or you can enter it manually.
