下一個要接收廣播及多重廣播訊息的用戶端窗口。當無線網 路基地台 (AP) 已經為相關的用戶端緩衝儲存了一些廣播流 量或是多重廣播訊息時,它就會傳送夾帶有下一個 DTM 間 隔值的 DTM。當 AP 用戶端聽到 beacon 訊號時,就會去接 收該廣播及多重廣播訊息。系統 DTIM 間隔的預設值為 1

前導序號格式(Preamble Type)

前導序號格式定義了無線基地台與無線用戶端的 CRC(Cyclic Redundancy Check)封包長度,預設前導序號 格式為短(Short Preamble),為了確保無線通訊為最高效 能,建議使用格式為短的前導序號格式

*CRC 是常見的探查封包傳輸是否有錯誤的一種技術。

SSID 廣播

此功能預設為啟用,若將 SSID 廣播關閉的話,無線用戶端 將無法在可用的無線網路清單之中看到 DI-624SSID 為 何,使用者必須自行手動輸入 SSID、頻道等相關設定才可 連線使用。

802.11g 模式

預設為關閉,代表同時可允許 802.11b 無線用戶端相容連線 使用;若將 802.11g 模式啟用的話,DI-624將只能允許 11g 無線用戶端使用。

CTS 模式

802.11g 11b 用戶端同時連上 DI-624 無線基地台時所提 供的進階保護模式,本保護模式會確保 11b 用戶端在傳輸資 料的同時, 11g 用戶端的傳輸速度不至於損失至與 11b 用 戶端一樣。預設為 Auto 自動偵測。

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.
