This article will guide you to open an extra Wi-Fi for your guests. It will only provide an internet connection and separately from the main network. For example, when you connect to the guest network, the device cannot access the local network, unable to log into the web interface, etc.
Note: Guest Network doesn't available in Access Point Mode.
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: Go to Advanced Settings->Guest Network.

Step 3: Create a 2.4GHz or 5GHz guest network according to your needs.
The default guest network is an open Wi-Fi named 'Cudy-Guest-2.4G' or 'Cudy-Guest-5G'.

Step 4: Set Encryption to WPA-PSK/WPA2-PSK Mixed Mode, then set an easy-to-remember password.

Step 5: 'Save & Apply' the settings. Now you can access your guest network using the SSID and password you set.
Don't enable Hidden Network unless you want to manually input this SSID for Wi-Fi access.

@Dear Edward,
Sorry, Cudy routers don’t have this function now. We will provide your feedback to the product department for evaluation.

@Dear Fernando,
What is the firmware version of your WR3000?
“I have a Cudy WR3000 set up with a guest network, but the problem is that devices connected to the guest network can see and communicate with each other, and I can’t find any option to disable this behavior. Of course, they are separated from the main LAN but devices on the guest network should not discover each other, specifically for IoTs. I know that on OpenWrt it’s just a matter of checking a box (isolate clients or similar), but I can’t find where the option is in Cudy or which firmware version offers this feature. Can you help me?”

@Dear Brain,
I need some more information to fix this issue.
1.What are the firmware version of your WR1500 and AP3000?
2. How do you install mesh system with them? via ethernet cable or wireless backhaul?
“I have setup mesh network with Cudy WR1500 as a Router Mode, and 2 items Cudy AP3000 as satelite mode.
I want to enable Guest WIFI and already setup the SSID with 2,4 Ghz and 5Ghz, but the SSID Guest WiFi cannot connect in my phone in Samsung A56 5G, error message (cannot get IP address).
Do you have any suggestion ?”
