This model has no web admin login. Manage it from the manufacturer's mobile app.

Deco X55 is a WiFi 6 mesh node, and nodes in this family expose no browser login page whatsoever. Everything runs through the Deco mobile app, authenticated with a TP-Link ID. No admin/admin exists because no admin console exists; the wireless name and its password are ones you choose while the app walks through setup.

Factory reset

Press the recessed Reset button underneath the unit with a pin and hold roughly one second. Watch the LED: flashing yellow means it is clearing, solid yellow means it is rebooting, and a pulsing blue glow means factory state has been reached. Launch the Deco app, sign in with your TP-Link ID, and build the network again.
