Frequently Asked Questions
What does "AC1200" mean in practice, and is it fast enough for streaming and gaming?
AC1200 is a dual-band Wi-Fi 5 standard: 300 Mbps on 2.4 GHz and 867 Mbps on 5 GHz, for a combined theoretical throughput of 1,200 Mbps. In real-world use on the 5 GHz band, you'll see 400–600 Mbps in good signal conditions — sufficient for 4K streaming, video calls, and casual gaming, though it's not the right choice for a household running simultaneous high-bandwidth tasks across many devices.
How does the mesh roaming work — will my device stay connected moving room to room?
The Deco M4 uses a single SSID across all nodes, and the system automatically hands off your device to the nearest node as you move. Most devices transition seamlessly; older devices with aggressive roaming settings may occasionally need a moment to reconnect.
How many Deco M4 units come in this kit, and can I expand the network later?
The listing should specify the node count in the kit (typically 2 or 3). You can add additional Deco units to the same network via the Deco app to extend coverage further — the system is designed to scale modularly.
What's the difference between this renewed unit and a new one?
Renewed units are factory-refurbished — tested, cleaned, and certified to function like new, typically with a limited warranty. Hardware performance is identical to a new unit; you may not receive original retail packaging. It's a cost-effective option when reliability matters more than unboxed condition.
Does the Deco M4 support wired backhaul between nodes?
Yes. Each Deco M4 node has two Ethernet ports, so you can run a wired backhaul connection between nodes if your home is pre-wired — significantly improving inter-node bandwidth compared to wireless backhaul.
