Frequently Asked Questions
Can I use this single Deco S4 unit as a standalone router?
Yes. The 1-pack works as a standalone router connected to your modem, providing up to 2,000 sq. ft. of WiFi coverage. You can add more Deco units later to extend the mesh network.
How do I set up and manage the Deco S4?
Setup is done entirely through the free Deco app on Android or iOS. The app walks you through connecting to your modem, naming your network, and configuring parental controls or a guest network — no web browser interface required.
Does the Deco S4 support both 2.4GHz and 5GHz bands?
Yes. It is a dual-band AC1200 system offering up to 300 Mbps on the 2.4GHz band and 867 Mbps on the 5GHz band, and it automatically steers devices to the optimal band.
Can I use the Deco S4 with my existing router instead of replacing it?
Yes. You can configure the Deco S4 in Access Point mode, which lets it work alongside your current router to extend coverage without creating a second network.
What parental controls does the Deco S4 offer?
The Deco app includes built-in parental controls that let you create profiles for family members, filter content by age, set daily time limits, and pause internet access for specific devices.
