Quick answer: Deco X55 setup and behavior depend on the exact model, hardware revision, pack and whether the system runs as router or access point.
What this page covers
Use TP-Link’s current support/download page and the Deco app for the matching hardware.
Step-by-step workflow
- Confirm the X55 model and hardware revision.
- Set up the main unit and add nodes through the documented app flow.
- Choose router or AP mode based on the upstream topology.
- Test wired backhaul, guest network and firmware update behavior.

| UI or firmware | Menus and behavior can change | Check the exact version or revision |
| Unknown detail | No safe universal claim is made | Use the official support path |
Limits and verification
Coverage and device-count figures are manufacturer claims; walls, client radios and placement change real results.
