Roomba won't connect to Wi-Fi

DIRECT ANSWER

Most Roomba Wi-Fi failures are band problems — many models only join 2.4 GHz networks. Put your phone on the 2.4 GHz band, redo setup within 10–15 ft of the router, then reboot robot and router.

COMMON CAUSES · RANKED

1

No usable 2.4 GHz network MOST COMMON

5 GHz-only networks, or routers that merge both bands under one name and steer the phone to 5 GHz, break setup on models that need 2.4 GHz.

2

Dock too far from the router

iRobot suggests 10–15 ft with few walls in between during setup. A weak signal drops the robot offline afterwards too.

3

Password or network changed

New router, renamed network, or a typo in the password — the robot keeps trying credentials that no longer exist.

4

Phone-side blockers UNCOMMON

An active VPN, Bluetooth turned off (newer models pair over Bluetooth first), or missing app permissions can stall setup at the searching screen.

5

iRobot cloud outage RARE

The robot joins your network but the app still shows it offline. Nothing to fix at home — wait it out.

HOW TO FIX IT

No battery or electrical work involved in this fix.

Get on the 2.4 GHz band

In your router settings, split combined bands into separate names, then connect your phone to the 2.4 GHz one before touching the app.

Move the robot next to the router

For setup only. Once connected, you can return the dock to its usual spot and check the signal holds.

Re-run the Wi-Fi setup

In the app, open Product Settings, then Wi-Fi Settings, and choose Change Product Wi-Fi. Retype the password slowly.

Reboot all three devices

Router off for 10 seconds, robot rebooted (hold CLEAN until the tone), app force-closed and reopened.

Rule out an outage before resetting

If the robot connected fine yesterday and nothing changed, check iRobot's support channels for a cloud outage before you factory-reset anything.
