For more information about the wireless channel frequencies, click the link to the online
document
“Wireless Networking Basics” in Appendix B .
• Security Options . These options are the wireless security features that you can enable.
The security options displayed in this screen might change depending on the wireless

Configuring WEP Wireless Security
WEP Shared Key authentication and WEP data encryption can be defeated by a determined
eavesdropper using publicly available tools.
WEP offers the following options:
• Open System . With Open System authentication and 64 or 128 bit WEP data encryption, the
WNDR3300 does perform data encryption but does not perform any authentication. Anyone
can join the network. This setting provides very little practical wireless security.
• Shared Key . With Shared Key authentication, a wireless device must know the WEP key to
join the network. Select the encryption strength (64 or 128 bit data encryption). Manually
enter the key values, or enter a word or group of printable characters in the
Passphrase field.
Manually entered keys are not case-sensitive, but passphrase characters are case-sensitive.
• Automatic . The wireless router automatically detects whether Open System or Shared Key is
used.
