Recognize the right fields
- Model / hardware version
- Match X55 and its revision; X55 Pro has separate documentation.
- Default Wi-Fi name
- The product label identifies the setup network. After setup, use your chosen network.
- Owner TP-Link ID
- The owner account password signs in to supported web management; it is not a label password.
Find the Wi-Fi settings
- Deco app: More
- Wi-Fi Settings
- Save
Connect to your own router’s Wi-Fi or Ethernet first. Opens in a new tab.
Check the hardware version on the label. The X55, X55 Pro, and other Deco products have separate documentation. Browser features depend on the installed firmware.
Start with the Deco app
Use the official Deco app for initial setup and everyday network management. Sign in to the TP-Link account that owns the network. Selecting a different account may leave you looking at an empty network list even when the Wi-Fi is working.
Open the web interface
- Join the Deco network from your computer or phone.
- Open tplinkdeco.net. A default Deco LAN address is 192.168.68.1; use the current address if it changed.
- For supported firmware, sign in with the owner TP-Link ID password. A manager account is not equivalent to the owner account for web access.
Change the network name or Wi-Fi password in the app
- Connect your phone to the Deco Wi-Fi and open the Deco app for this network.
- Choose More → Wi-Fi Settings.
- Edit the Wi-Fi name or password, then tap Save.
- Reconnect affected devices using the saved details. The new Wi-Fi key does not replace your TP-Link ID password.
The linked TP-Link walkthrough uses example app screens; available controls vary with software and model. Use the app for settings missing from the browser.
Recover the owner account, not the Wi-Fi key
- Confirm you can receive email at the address used for the network owner's TP-Link ID.
- On the Deco app's sign-in screen, choose Forgot Password? and enter that email address.
- Use the reset message to choose a replacement account password, then sign back into the app.
If you are still signed in, TP-Link's reset guide requires signing out first; make sure you know the owner email and can reach its inbox before doing so. A factory reset is not an account-password recovery method. See which password to recover before removing configuration.
The app works but the browser does not
Check More → Advanced → LAN IP in the app for the current address, then confirm that your browser device is on this Deco network. In access-point mode, a connected device's gateway may identify the upstream router instead. Check X55 hardware and firmware support before interpreting a missing web interface as a fault; do not reset a working mesh merely to expose a browser feature.
Check access for this model
Join the Deco network. Supported X55 firmware offers tplinkdeco.net and a default address of 192.168.68.1; the address can change. Use the Deco app for settings unavailable in the browser.
When a password is rejected
Use Forgot Password for the owner TP-Link ID in the official Deco sign-in flow. You need access to that account’s email inbox to follow the recovery message. Resetting the Deco does not recover the online account.
Recover the owner TP-Link ID through the official Deco sign-in flow. Selecting another account may show an empty network list.

When several devices lose internet
Check whether Deco is in router or access-point mode. In access-point mode, the upstream router provides routing; include that device and your provider connection in the checks.
