- How many units do I need?
- One unit covers a small apartment, two suit a medium home, and three are meant for larger multi-floor houses. Add units later if you find dead spots.
- Does it support wired backhaul?
- Yes. Each unit has gigabit Ethernet ports, so you can connect them by cable for faster, more stable links between units.
- Is it better than the Deco X90?
- The X90 is tri-band with a dedicated backhaul band and higher throughput. The X55 is dual-band and simpler, which suits lighter households.
- Does it work with older Wi-Fi devices?
- Yes. It is backward compatible with Wi-Fi 5, Wi-Fi 4 and older standards, so legacy phones and smart devices still connect.
- Can I manage it without the app?
- Setup and most management go through the Deco app. There is a web interface, but it exposes fewer settings than the app.
- Does it support WPA3?
- Yes. It supports WPA3 along with WPA2 and WPA, and it is IPv6 compatible.
