-ASCII

-Hex

•WEP Keys—You can specify up to four WEP keys. In each text box, enter a string of characters for each key. The keys you enter depend on the key type selected:

-ASCII—Includes uppercase and lowercase alphabetic letters, the numeric digits, and special symbols such as @ and #.

-Hex—Includes digits 0 to 9 and the letters A to F.

Use the same number of characters for each key as specified in the Characters Required field. These are the RC4 WEP keys shared with the stations using the WAP device.

Each client station must be configured to use one of these same WEP keys in the same slot as specified on the WAP device.

•Characters Required—The number of characters you enter into the WEP Key fields is determined by the key length and key type you select. For example, if you use 128-bit ASCII keys, you must enter 26 characters in the WEP key. The number of characters required updates automatically based on how you set the key length and key type.

•802.1X Authentication—The authentication algorithm defines the method used to determine whether a client station is allowed to associate with WAP device when static WEP is the security mode.

Specify the authentication algorithm you want to use by choosing one of these options:

-Open System authentication allows any client station to associate with the WAP device whether that client station has the correct WEP key or not. This algorithm is also used in plaintext, IEEE 802.1X, and WPA modes. When the authentication algorithm is set to Open System, any client can associate with the WAP device.

NOTE Just because a client station is allowed to associate does not ensure it can exchange traffic with an WAP device. A station must have the correct WEP key to be able to successfully access and decrypt data from the WAP device, and to transmit readable data to the WAP device.

-Shared Key authentication requires the client station to have the correct WEP key in order to associate with the WAP device. When the authentication algorithm is set to Shared Key, a station with an incorrect WEP key cannot associate with the WAP device.

WAP121, WAP321 specifications

Cisco Systems has long been recognized for its innovation in networking technologies, and the Cisco WAP321 and WAP121 access points are prime examples of its commitment to delivering reliable, high-performance wireless networking solutions for small and medium-sized businesses. These devices offer a robust set of features designed to meet the requirements of modern wireless networking while ensuring ease of use and deployment.

The Cisco WAP321 is a dual-band access point that operates in both the 2.4 GHz and 5 GHz frequency bands, providing flexibility and improved performance in crowded environments. With support for the 802.11n Wi-Fi standard, it boasts a combined data rate of up to 450 Mbps, enabling high-speed connections for multiple users simultaneously. The WAP321 also includes advanced features such as multiple SSIDs and VLAN support, allowing businesses to segment their networks for enhanced security and management control.

One of the standout characteristics of the WAP321 is its ability to act as a lightweight access point, meaning it can be managed through a Cisco Wireless LAN Controller (WLC) for larger deployments. This capability allows for centralized management of multiple access points, making it easier for IT administrators to deploy, configure, and monitor their network infrastructure.

On the other hand, the Cisco WAP121 is designed for those requiring a simpler, more cost-effective solution. This single-band access point also operates on the 2.4 GHz band but still provides robust performance with wireless speeds reaching up to 300 Mbps. It is ideal for small businesses looking to develop or expand their wireless networks without the complexities associated with more advanced systems.

Both models feature Power over Ethernet (PoE) capability, enabling them to receive power through the Ethernet cable, which simplifies installation and reduces the need for additional power outlets. Additionally, they support advanced security protocols, including WPA/WPA2 encryption, ensuring that sensitive data transmitted over the network remains protected from unauthorized access.

The ease of setup and user-friendly management interfaces of both the WAP321 and WAP121 make them appealing options for businesses lacking extensive IT resources. With features aimed at enhancing both performance and security, these access points represent powerful tools for achieving reliable wireless connectivity in a business environment. Whether organizations opt for the WAP321 for its extensive capabilities or the WAP121 for its simplicity, both access points reflect Cisco's dedication to meeting diverse networking needs.
