IP/MAC Binding, namely, ARP (Address Resolution Protocol) Binding is used to convert a network address (e.g. IPv4 address) to a physical address such as a MAC address.
Step 1: Open a web browser and go to http://cudy.net or http://192.168.10.1.
For details, please refer to How to log into the web interface of Cudy Router?
Step 2: Click Advanced Settings -> IP/MAC Binding in the Security section.


Step 3: Click Add to append one entry to the list. Select the device from the MAC-Address list and enter IP address that you want to bind. Enter a Description for this binding entry.

Step 4: Save & Apply the settings.
You can go to System Status->Devices to check if the IP Address changed successfully or not.

Note:
The IP Address release time can be changed in DHCP. Or you can disable and enable the Wi-Fi or unplug and plug back the Ethernet cable to release the IP Address manually.

@Dear John,
We will provide your feedback to the product department for evaluation.
“Thanks for the feedback! Since my main router occasionally blocks MAC addresses, adding a MAC-cloning or rotation feature would be a huge help. Do you plan to include this in a future update, and if so, when?
Also, is there a way to force the Cudy router to only connect to the 2.4 GHz band in WISP mode? My main router broadcasts both 2.4 GHz and 5 GHz under the same name. The Cudy keeps automatically switching to the 5 GHz band, which has a weaker signal, causing frequent internet dropouts."

@Dear John,
Cudy routers don’t support this function now. We will provide your feedback to the product department for evaluation.
“Hello, what is the status of firmware feature to randomize MAC address of my cudy wr 1500 in WISP mode? Is it ready yet or when is it expected? Thanks!”

@Dear Helix,
All Cudy routers support MAC clone for WAN interface function. You can find it on “General Settings” - “WAN Mode” -“Advanced” —“Mac Clone” page.
“I just want to know if it supports MAC address cloning”
