Compact Wireless-G USB Network Adapter with SpeedBooster

1.Disable Broadcast

2.Make it unique

3.Change it often

Most wireless networking devices will give you the option of broadcasting the SSID. While this option may be more convenient, it allows anyone to log into your wireless network. This includes hackers. So, don’t broadcast the SSID.

Wireless networking products come with a default SSID set by the factory. (The Linksys default SSID is “linksys”.) Hackers know these defaults and can check these against your network. Change your SSID to something unique and not something related to your company or the networking products you use.

Change your SSID regularly so that any hackers who have gained access to your wireless network will have to start from the beginning in trying to break in.

MAC Addresses. Enable MAC Address filtering. MAC Address filtering will allow you to provide access to only those wireless nodes with certain MAC Addresses. This makes it harder for a hacker to access your network with a random MAC Address.

WEP Encryption. Wired Equivalent Privacy (WEP) is often looked upon as a cure-all for wireless security concerns. This is overstating WEP’s ability. Again, this can only provide enough security to make a hacker’s job more difficult.

There are several ways that WEP can be maximized:

1.Use the highest level of encryption possible

2.Use “Shared Key” authentication

3.Change your WEP key regularly

WPA. Wi-Fi Protected Access (WPA) is the newest and best available standard in Wi-Fi security. Four modes are available: WPA-Personal, WPA2-Personal, WPA-Enterprise, and RADIUS. WPA-Personal gives you a choice of two encryption methods: TKIP (Temporal Key Integrity Protocol), which utilizes a stronger encryption method and incorporates Message Integrity Code (MIC) to provide protection against hackers, and AES (Advanced Encryption Standard), which utilizes a symmetric 128-Bit block data encryption. WPA2-Personal only uses AES encryption, which is stronger than TKIP. WPA-Enterprise offers two encryption methods, TKIP and AES, with dynamic encryption keys. RADIUS (Remote Authentication Dial-In User Service) utilizes a RADIUS server for authentication.

Important: Always remember that each device in your wireless network MUST use the same encryption method and encryption key or your wireless network will not function properly.

WUSB54GSC specifications

The Cisco Systems WUSB54GSC is a versatile wireless USB adapter designed to provide users with high-speed internet access by connecting to wireless networks. This adapter represents a significant step in wireless technology, making it easy to upgrade desktops and laptops to Wi-Fi capability, particularly in environments where it is not feasible to connect to a modem or router through a wired connection.

One of the standout features of the WUSB54GSC is its compliance with the IEEE 802.11g standard, allowing for data transfer rates of up to 54 Mbps. This makes it suitable for various online activities, including web browsing, streaming media, and online gaming. The device also supports backwards compatibility with the older 802.11b standard, ensuring that users can connect to a wider range of wireless networks regardless of their configuration.

Another significant characteristic of the WUSB54GSC is its compact and portable design. The adapter is small enough to fit into a pocket, making it ideal for users who are constantly on the move. Its plug-and-play functionality also means that users can easily install it without the need for complicated configuration processes. The adapter's integration with Windows and other operating systems ensures a seamless experience, allowing users to connect to their networks with minimal setup.

The WUSB54GSC also features advanced security options to protect users' data and safeguard their connections. It supports various encryption protocols, including WEP, WPA, and WPA2, helping to create a secure wireless environment and protecting against unauthorized access. This ensures that sensitive information remains confidential while users enjoy the benefits of wireless technology.

Moreover, the WUSB54GSC is equipped with Cisco's "Wi-Fi Protected Setup" (WPS), which simplifies the process of connecting to secure wireless networks. By simply pressing a button on the router and the adapter, users can quickly establish a secure connection without remembering complex passwords.

In summary, the Cisco Systems WUSB54GSC is a reliable and user-friendly wireless USB adapter that combines portability, speed, and security. Its compliance with modern wireless standards, along with its robust security features, makes it an excellent choice for users looking to enhance their wireless connectivity experience. Whether for home, office, or travel use, the WUSB54GSC stands as a valuable tool in today's digital age.
