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.
Decision table
| Check | What it tells you | Safe next action |
|---|---|---|
| Exact scope | The page is limited to the named model, platform or provider | Match the current official source |
| 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.
