failure mode
Roomba i2 Wi-Fi / app won't connect; schedule or voice fails
Symptom: The iRobot Home app can't find or set up the robot, the robot drops off Wi-Fi, scheduled cleans don't run, or Alexa/Google voice commands stop working. The robot itself still cleans from the CLEAN button. Likely root causes: Trying to join a 5 GHz network — the i2 only supports 2.4 GHz Wi-Fi; Weak Wi-Fi signal where the Home Base sits, or router too far; Wrong Wi-Fi password, or phone not on the same 2.4 GHz network during setup; Router settings (band steering, AP/client isolation, MAC filtering, captive portal); App or robot software glitch; account/cloud outage affecting voice; Robot needs a reboot or re-pair after a router/password change Next steps if owner-level checks fail: Robot connects but repeatedly drops off — signal/router issue; relocate base or add a 2.4 GHz extender; App still can't find the robot after re-pair on a confirmed 2.4 GHz network — contact iRobot Customer Care 1-877-855-8593
