How to set up Deco to work in Access Point mode?

Note: In AP mode, any router features will be non-configurable (including Parental Controls, Antivirus, Port Forwarding, Address Reservation, and QoS, etc), as all the IP addresses are assigned and controlled by the root router (not Deco).

3. Can I change the IP range of Deco? Can I change it to another subnet?
The default LAN IP of the main Deco unit is 192.168.0.1, and the default DHCP range is 192.168.0.100-192.168.0.199.
Deco will detect the IP conflict with the front-end modem or router. For example, if the front-end router has the LAN IP address of 192.168.0.1, then Deco will change its own IP range to 192.168.1.x.
Currently Deco M5/P7/M9 Plus has the option to change the LAN IP settings. For other Deco models, this feature will come soon in future updates.

4. How many devices can be connected to a Deco network?
The number of client devices that can be connected at once depends on the type of devices connected and the usage mix of those devices.
The Deco system supports to connect over 100 devices in homes with a mix of IoT products, smart TVs, smartphones, tablets and peripherals, such as wireless printers.
