所以在設定 WPA 之前,您必須已安裝並設定好 Radius 伺服器(例如 Windows 2000 Server),以供 DI-

624連接設定使用。

WPA-PSK

預先共用金鑰(WPA-PSK),只需要在 DI-624上輸入單 一密碼。只要密碼相符,用戶端便會獲得無線網路的 存取權限。

WPA 不同的是,使用 WPA-PSK加密是不需要 Radius 伺服器做認證的,您只要在此輸入金鑰以供認 證使用即可,可設定的金鑰長度為 8-64個字元(至少 8 個字元)

當然,不管您選擇了以上何種的認證(加密)方式,相對 的使用者的無線網路卡也必須支援才行。

WEP

Wired Equivalent Protocol (WEP) 是一種提供無線區域網路 (WLAN) 所使用的無線通訊安全協定。WEP 是一種對稱性的 加密技術,藉由加密在 WLAN 上傳送的資料,為資料保密 提供了相當的安全性。WEP 必須有相同 WEP key 的雙方 (TX RX) 才可互相聽得懂。

DI-624支援了二種層級的 WEP 加密方式,分別為: 64 位 元加密、128 位元加密,越長的加密代表越安全。

您可以選擇啟用/停用 WEP 加密功能,在預設情況下,WEP 加密功能是停用的。

金鑰類型

DI-624 所支援的金鑰類型為「HEX(十六進位數字) ASCII (American Standard Code for Information Interchange)。使用者可以變更金鑰類型以符合現有的無線 網路設定或是自訂化自己的無線網路設定。

DI-624 specifications

The D-Link DI-624 is a wireless router that has gained recognition for its robust performance and versatile features. Designed to cater to home and small office networks, this router provides users with high-speed wireless connectivity along with a range of functionalities that enhance networking capabilities.

One of the main features of the D-Link DI-624 is its compliance with the Wireless G standard (IEEE 802.11g). This allows for wireless transmission speeds of up to 54 Mbps, which is suitable for activities like web browsing, email, and streaming multimedia content. The DI-624 also supports backward compatibility with the older Wireless B standard, ensuring that users with older devices can connect without issues.

Security is a top priority for the D-Link DI-624, as it includes multiple features to safeguard the network. The router supports WPA (Wi-Fi Protected Access) and WEP (Wired Equivalent Privacy) encryption methods, allowing users to choose their preferred level of security for wireless communications. Additionally, the DI-624 comes equipped with a built-in firewall that helps protect against potential threats from the internet.

The DI-624 features a user-friendly web-based interface, making it easier for users to set up and manage their network settings. This interface is accessible through any web browser, allowing users to customize options like wireless network names, password settings, and parental controls. The router also includes DHCP (Dynamic Host Configuration Protocol), which simplifies IP address management for connected devices.

In terms of connectivity, the D-Link DI-624 is equipped with four 10/100 Ethernet ports, which enable users to connect wired devices for a stable internet connection. This dual capability of both wired and wireless connections offers flexibility when building a network.

Another notable characteristic of the D-Link DI-624 is its ability to support multiple SSIDs (Service Set Identifiers). This allows users to create separate networks for guests, ensuring that primary network resources remain secure and accessible only to authorized devices.

In summary, the D-Link DI-624 is a reliable and feature-packed wireless router ideal for small networks. With a combination of wireless performance, security measures, ease of management, and versatile connectivity options, it remains a solid choice for users looking to establish a robust home or small office network.
