(do not use any spaces). Make sure this setting is the same for all devices in your wireless network. For added security, Linksys recommends that you change the default SSID (linksys) to a name of your choice.
Wireless-B Ethernet Bridge • WEP - To enable WEP encryption, click the Enable radio button. To increase wireless network security, using WEP encryption is strongly recommended. Then click the Edit WEP Settings button to configure the WEP settings. To disable WEP encryption, keep the default, Disable. An acronym for Wired Equivalent Privacy, WEP is an encryption method used to protect your wireless data communications.
(The Passphrase function is compatible with Linksys wireless products only. If you want to communicate with non-Linksys wireless products, you will need to enter your WEP key(s) manually on the non-Linksys wireless products.) After you enter the Passphrase, click the Generate button to create WEP key(s).

Wireless-B Ethernet Bridge 4. The Bridge-enabled PC won’t communicate with a wireless-enabled PC or printer. Perform the following steps: • Check that the wireless-enabled PC or printer is on the same wireless network as the PC using the Bridge. • Make sure that the SSID and network mode are identical for all devices connected to the same wireless network.

Wireless-B Ethernet Bridge Can I play multiplayer games with other users of the wireless network? Yes, as long as the game supports multiple players over a LAN. Refer to the game’s user guide for more information. What is ad-hoc mode? When a wireless network is set to ad-hoc mode, the wireless-equipped computers are configured to communicate directly with each other.

Wireless-B Ethernet Bridge worldwide. This presents a truly revolutionary opportunity to place convenient high speed wireless capabilities in the hands of users around the globe. 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.
Wireless-B Ethernet Bridge Appendix B: Wireless Security A Brief Overview Whenever data—in the form of files, e-mails, 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.

Wireless-B Ethernet Bridge 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 32
Wireless-B Ethernet Bridge 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 33
Wireless-B Ethernet Bridge 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.

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.

Wireless-B Ethernet Bridge PCs unprotected by a firewall router should at least run firewall software, and all PCs should run up-to-date antiviral software. 8) WEP Wired Equivalent Privacy (WEP) is often looked upon as a panacea for wireless security concerns. This is overstating WEP's ability.
Linksys wireless products only. If you want to communicate with non-Linksys wireless products, you will need to enter your WEP key(s) manually on the non-Linksys wireless products.) If you are not using a Passphrase, then you can enter one or more WEP keys manually.
