Safeguarding Your Network

11N Channel or 11G Channel. These fields determine which operating frequency is used 
for the 11N or 11G wireless networks. It should not be necessary to change the wireless 
channel unless you notice interference problems with another nearby wireless network.

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.
