Configure Wireless Security
Your wireless data transmissions should be protected from potential
eavesdroppers. An eavesdropper might set up a compatible wireless
adapter within range of your device and attempt to access your network.
You can protect your network from eavesdroppers by encrypting wireless
data transmissions. Data encryption is the translation of data into a form
that cannot be easily understood by unauthorized users.
There are two methods of wireless security to choose from:

Configure Wireless Authentication/Encryption
To configure your Wireless authentication/encryption settings, follow the
steps below:

Encryption including the following options:
−
Off – no encryption will be performed on the wireless network.
−
Wired Equivalent Privacy (WEP); data is encrypted into blocks of
either 64 bits length or 128 bits length. The encrypted data can
only be sent and received by users with access to a private
network key. Each PC on your wireless network must be manually
configured with the same key as your device in order to allow
wireless encrypted data transmissions. Eavesdroppers cannot
access your network if they do not know your private key. WEP is
considered to be a low security option.
Authentication, including the following options:
−
None – allowing any wireless client to associate to your HM490dp
under the same SSID and channel.
−
MAC association which gives you the choice to only allow a
particular list of PCs to connect to your wireless network.
−
Wi-Fi Protected Access (WPA); provides a stronger data
encryption method (called Temporal Key Integrity Protocol (TKIP)).
It runs in a special, easy-to-set-up home mode called Pre-Shared
Key (PSK) that allows you to manually enter a pass phrase on all
the devices in your wireless network. WPA data encryption is
based on a WPA master key. The master key is derived from the
pass phrase and the network name (SSID) of the device.
