有些使用者嘗試在家庭路由器上設定 Mac 過濾來管理連接到範圍擴展器的用戶端，但他們最終發現他們的設定無法正常運作。在這裡，我們將概述原因以及如何使其工作的全面說明。 br data-mce-fragment="1">
準備工作：
1.確保已透過路由器成功配置範圍擴展器。在範圍擴充器的 Web 介面中，前往進階設定->MAC 中繼器並啟用它。
由於其工作機制，Range Extender 將以 Range Extender 建立的虛擬 MAC 位址與其每個客戶端的實際 MAC 位址進行交換。由於路由器會將客戶的虛擬MAC位址視為其實際MAC位址，因此我們需要在路由器的MAC過濾中輸入客戶的虛擬MAC位址，而不是其真實MAC位址。透過對比以下訊息，您可以更好地理解該過程。
第1 步：檢查您電腦的真實MAC 位址(74-86-E2-0E-0D-87)。 /p >
也可以在範圍擴展器的客戶端清單中檢查 IP 位址。
注意：大多數手機可能會使用私有MAC 位址，需要在裝置的WLAN 設定頁面上將其變更為裝置MAC 位址。 span> 第 2 步：然後檢查路由器 Web 介面上顯示的電腦的 MAC 位址。 （通常在 DHCP 頁面上）。這是您電腦的虛擬 MAC 位址 (B2:4B:D6:0E:0D:87) 注意：您也可以找到顯示為無線設備的計算機，因為該計算機已連接到以無線方式連結到路由器的範圍擴展器。 步驟3：如您所見，路由器只能看到您電腦的虛擬MAC位址，而不是真實的MAC位址。並且有一條規則，您可以發現 MAC 位址的最後六個字元是相同的。
真實 MAC 位址：74:86:E2:0E:0D:87 虛擬 MAC 位址：B2:4B:D6:0E:0D:87 第4 步： 找到列印在底部標籤上的範圍擴展器的真實MAC 位址並寫下完成(B4:4B:D6:25 : FE：C4）。
再次進入路由器的客戶端列表，您會發現 'B2:4B:D6:25:FE:C4' 和 'B2:4B:D6:25:FE :C6 ' 是範圍擴展器的MAC 位址。
注意：對於雙頻範圍擴展器，它透過兩個頻段與路由器通信，因此您需要將兩個頻段的 MAC 位址MAC 過濾器清單中的範圍擴展器。
第 5 步： 選擇"僅允許清單（類似白名單）"並新增特定的虛擬 MAC 位址您想要上網的設備。
如果您希望將其他裝置新增至清單中，您需要找出虛擬MAC 位址並將其新增至路由器的MAC 過濾清單中。 >

@Dear Afeef,
There are two settings may override the MAC Filter.
1. SPI Firewall. Enabled by default. If you disable it on the web page. The MAC Filter will not work.
2. IPv6. The firewall is not working on IPv6 traffics now. So If you enable the IPv6 function. The IPv6 traffics will still work even if you enable the MAC filter function. You can disable IPv6 and check again.
“Dear Cudy Technical Support,
I have a problem with the MAC Filter function on my Cudy router, and I would appreciate your technical clarification.
Router model:
Cudy WR3000 V1.0
Firmware version:
2.4.19-20250829-192837
Operating mode:
Main Router Mode"
Dear Cudy Technical Support,
I have a problem with the MAC Filter function on my Cudy router, and I would appreciate your technical clarification.
Router model:
Cudy WR3000 V1.0
Firmware version:
2.4.19-20250829-192837
Operating mode:
Main Router Mode
The problem is that when I add a device’s MAC address to the MAC Filter blacklist/block list, the device is not blocked from Internet access. The device remains connected to the Wi-Fi and can still access the Internet normally.
I have already verified the following:
The router is operating in Main Router Mode. I am using the MAC address shown by the router in the connected devices/client list. The MAC address is added to the MAC Filter block list. MAC Filter is enabled. I applied/saved the configuration. I disconnected and reconnected the client to Wi-Fi after applying the rule. The client still has full Internet access.I am not referring to the Parental Control/Web Filter or domain blacklist. My issue is specifically with the MAC Filter / MAC Access Control function, where I expect a blocked MAC address to lose Internet access.
Could you please clarify:
1. Is MAC Filter fully supported and working on WR3000 V1.0 with firmware 2.4.19?
2. When using “Allow all except listed”, should a listed MAC address be completely prevented from accessing the Internet?
3. Are there any known bugs or limitations with MAC Filter in firmware 2.4.19?
4. Does MAC Filter behave differently between the 2.4 GHz and 5 GHz networks?
5. Does the MAC Filter work differently when Private/Random MAC Address is used by the client?
6. Are there any other settings that could override or bypass the MAC Filter?
7. If this is a firmware issue, is there a newer beta firmware or recommended workaround that fixes it?
I would appreciate it if you could explain why the blocked device is still able to access the Internet and provide the correct configuration or troubleshooting steps.
Thank you for your support.
Best regards,
Afeef
