您也可以勾選 Auto SelectDI-624會自動選擇環境中干擾 最少的頻道來供無線網路傳輸使用。

加密方式

此設定項目中主要為設定無線網路的使用權認證部份,認證 (Authentication) 的目的是確認對方身份的合法性,以免與身 份不明的對象溝通,洩漏了重要的機密。也就是雙方進行通 訊之前,必須先經過認證的程序。DI-624有支援的認證(加 密)方含以下四種;

開放系統/共用金鑰

IEEE 802.11 提供兩種基礎認證的服務:開放系統式 (Open System) 及共享密匙式 (Shared Key)開放系 統式 (Open System)IEEE 802.11 內定的認證方 法,也是 DI-624 預設所使用設定,即不認證,不過在 特殊的應用下,您還是可以自行決定使用何者。

1.如果選擇了「共用金鑰」,則無線網路基地台 (AP) 將不會被顯示於無線網路中,但是除了共用同一個 WEP 金鑰的無線用戶端,並且其 MAC 位址也必 須要在過濾器清單中出現且被允許存取。

2.如果選擇了「開放系統」,則只有擁有相同 WEP 金鑰的無線用戶端,可以繼續存在於該無線網路 上,但是無線網路基地台 (AP) 則會被在網路上的 所有裝置看見。

WPA

WPA 802.1x 和延伸認證協定(EAP)作為其認證機 制的基礎。認證機制是由使用者提供某種型式的證明 「身分證明」,然後存取網路並以該證明來對照合法 使用者資料庫(Radius 伺服器)進行檢查。任何要登入 網路的人都必須通過這樣的認證過程。

DI-624 支援了 WPA-EAP WPA-TKIP

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.
