Roborock Wi-Fi Setup Failing — Fix Guide

What Does This Error Mean?

Roborock only supports 2.4 GHz Wi-Fi. If your router is on 5 GHz only, or the password was entered incorrectly, setup will fail. Switching to 2.4 GHz and carefully re-entering the password fixes most Roborock Wi-Fi issues.

Affected Models

Roborock S5 Max
Roborock S6 Pure
Roborock S7
Roborock Q5+
Roborock S8 Pro Ultra

Common Causes

Router is set to 5 GHz only — Roborock requires 2.4 GHz
Wi-Fi password entered incorrectly in the app
Phone was on 5 GHz during setup — app sent wrong network credentials
Router has special characters in the SSID (network name) that confuse the robot
Router firmware issue causing 2.4 GHz band instability
Roborock firmware bug (fixed in updates)

How to Fix It

On your phone, disconnect from Wi-Fi and reconnect specifically to your 2.4 GHz network before opening the Roborock app.

If your router has separate names for 2.4 GHz and 5 GHz (e.g., 'HomeNetwork' and 'HomeNetwork_5G'), connect to the one without '_5G' before setting up the robot.
In the Roborock app setup wizard, enter the Wi-Fi password very carefully. Passwords are case-sensitive.

If your password contains special characters like @ # $ or !, double-check they are being entered correctly. On some phone keyboards, special characters are on different pages and can be mis-selected.
Place the Roborock and your phone within 2 metres of the router during initial setup.

A strong signal during the first connection is important. Move the robot to its permanent location after a successful initial setup.
If your router combines both 2.4 GHz and 5 GHz under a single network name (band steering), temporarily disable band steering in the router settings during robot setup.

Band steering can cause the robot to be pushed to the 5 GHz band which it cannot use. Disabling it temporarily allows the robot to connect to 2.4 GHz. Re-enable band steering after the robot is connected.
Check for a Roborock firmware update in the app. Several Wi-Fi connectivity bugs have been fixed in updates.

To update: ensure the robot is on the dock > open the Roborock app > Devices > your robot > More settings > Software Update.

When to Call a Professional

Wi-Fi failures are almost never hardware faults on the robot. If all steps fail, contact Roborock support at roborock.com/support.

Frequently Asked Questions

Do I need Wi-Fi to use my Roborock?

You need Wi-Fi for the initial setup and to access app features like scheduling, mapping, and room cleaning. After setup, if the robot loses Wi-Fi, it will continue to clean when you press the physical button on the robot. However, for the full experience (maps, scheduled cleans, room-specific cleaning), a stable Wi-Fi connection is required.

My Roborock was working on Wi-Fi and suddenly went offline — why?

Sudden disconnection is usually caused by a router reboot, a Wi-Fi password change, or the robot moving to a weak signal area. In the Roborock app, go to Devices > your robot > Wi-Fi settings to reconnect. If the router password changed, you will need to go through the setup process again for the robot.
