Reference Manual for the Model DG834G Wireless ADSL Firewall Router
Wireless Configuration 4-9
Restricting wireless access prevents intruders from connecting to your network. However, the
wireless data transmissions are still vulnerable to snooping. Using the WEP data encryption
settings described below will prevent a determined intruder from eavesdropping on your wireless
data communications. Also, if you are using the Internet for such activities as purchases or
banking, those Internet sites use another level of highly secure encryption called SSL. You can tell
if a web site is using SSL because the web address begins with HTTPS rather than HTTP.
Authentication Type Selection
The DG834G lets you select the following wireless authentication schemes.
• Automatic
• Open System
• Shared key
Set your wireless adapter according to the authentication scheme you choose for the DG834G
wireless router. Please refer to “Authentication and WEP” on page D-3 for a full explanation of
each of these options, as defined by the IEEE 802.11b wireless communication standard.
Encryption Choices
Please refer to “Overview of WEP Parameters” on page D-5 for a full explanation of each of the
following choices, as defined by the IEEE 802.11b wireless communication standard. Choose the
encryption strength from the drop-down list:
Disable
No encryption will be applied. This setting is useful for troubleshooting your wireless connection,
but leaves your wireless data fully exposed.
64 or 128 bit WEP
When 64 Bit WEP or 128 Bit WEP is selected, WEP encryption will be applied.
Note: The authentication scheme is separate from the data encryption. You can choose
an authentication scheme which requires a shared key but still leave the data
transmissions unencrypted. If you require strong security, use both the Shared Key and
WEP encryption settings.
