Overview of security settings

To help improve the security of the wireless network and prevent unauthorized access, the printer

supports many common types of network authentication, including WEP, WPA, and WPA2.

• 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 hard 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.

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.
