Connect the Broadband Router
A
Before you begin, make sure
that you have the setup infor-
mation for your specific type of
Internet connection. The instal-
lation technician from your ISP
should have left this informa-
tion with you after installing
your broadband connection. If
not, you can call your ISP to
request the settings.
B
Make sure that all of your net-
work's hardware is powered off,
including the Router, PCs, and
cable or DSL modem.
C
Connect one end of an Ether-
net network cable to one of
the ports (labeled 1-4) on the
back of the Router, and the
other end to an Ethernet port
on a PC.
D
C
Repeat this step to connect
additional PCs or other network
devices to the Router.
E
Connect a different Ethernet
network cable from your cable
or DSL modem to the Internet
port on the Router's back
panel. This is the only port that
will work for your modem con-
nection.

  • Page 68 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. 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 70: Appendix B: Wireless Security

    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.
  • Page 71 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.
  • Page 72 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.
  • Page 73 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.
  • Page 74 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 75 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.
  • Page 76: Figure B-2: Wep

    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.
