● WEP: Provides security by encrypting data sent over radio waves from one wireless device to
another wireless device. Devices on a WEP-enabled network use WEP keys to encode data. If
your network uses WEP, you must know the WEP key(s) it uses.
● WPA: Increases the level of over-the-air data protection and access control on existing and
future wireless networks. It addresses all known weaknesses of WEP, the original native security
mechanism in the 802.11 standard. WPA uses the Temporal Key Integrity Protocol (TKIP) for
encryption and employs 802.1X authentication with one of the standard Extensible
Authentication Protocol (EAP) types available today.
● WPA2: Provides enterprise and consumer wireless users with a high level of assurance that only
authorized users can access their wireless networks. WPA2 provides the Advanced Encryption
Standard (AES). AES is defined in counter cipher-block chaining mode (CCM) and supports the
Independent Basic Service Set (IBSS) to enable security between client workstations operating
connected wirelessly without a wireless router (such as a Linksys wireless router or Apple
AirPort Base Station).
Add hardware addresses to a wireless router (MAC filtering)
MAC filtering is a security feature in which a wireless router or wireless access point is configured
with a list of hardware addresses (also called "MAC addresses") of devices that are allowed to gain
access to the network through the router.
If the router filters hardware addresses, then the printer's hardware address must be added to the
router's list of accepted hardware addresses. If the router does not have the hardware address of a
printer attempting to access the network, the router denies the printer access to the network.
CAUTION: This method is not recommended, however, because your MAC addresses can easily
be read and falsified by unwanted users outside your network.
To add hardware addresses to a wireless router or wireless access point
1. Print the network configuration page, and then locate the printer's hardware address. For more
information, see Understand the network configuration page on page 152.
NOTE: The printer maintains separate hardware addresses for the Ethernet connection and for
wireless connection. Both hardware addresses are listed on the printer's network configuration
page.
2. Open the configuration utility for the wireless router or wireless access point, and add the
printer's hardware address to the list of accepted hardware addresses.
NOTE: For more information about using the configuration utility, see the documentation provided
with the router or wireless access point.
Other wireless security guidelines
To keep the wireless network secure, follow these guidelines:
● Use a wireless password with at least 20 random characters. You can use up to 64 characters in
a WPA wireless password.
● Avoid any common words or phrases, easy sequences of characters (such as all 1s), and
personally-identifiable information for wireless passwords. Always use random strings composed
of uppercase and lowercase letters, numbers, and if allowed, special characters such as
punctuation.
