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 Adamx,
You can try to disable the “SPI Firewall” function on “Advanced Settings” —“Firewall” page. Then, you can access the devices that connect to the Guest Network. The devices connected to the Guest Network will be in a seperate subnet and you can access.

@Dear Nick,
We will add these features of the router to the Cudy APP one by one. Our R&D team are working on this. But still need some time.
“A critical setting that’s missing from the Cudy app is Access Filter within the guest WiFi setting
I was totally baffled by why I wasn’t able to turn off internet access to devices connected to the guest network until I found this setting in the web interface.
Also, why does the configuration allow me to toggle off internet access to devices on the guest network when it won’t work due to this setting being disabled? Surely it makes sense to have a popup saying “Access Filter for your guest network is disabled. Therefore this feature won’t work.”"
@Dear tsikis,
Thank you for your kindly advice! We will provide your feedback to the product department for evaluation.
