iRobot Roomba i5 won't connect to wifi: what to do
Robot fails to connect during setup or the app reports 'connection failed'.
We could not fully consult the manufacturer's support page for this model; the steps are general and may differ in details.
Most likely causes
Phone is on a 5 GHz network while the Roomba needs 2.4 GHz
- Check your phone's Wi‑Fi settings to see if it is connected to 2.4 GHz or 5 GHz.
- Switch your phone to the 2.4 GHz network or make the 2.4 GHz SSID visible on your router.
- Try the setup again in the app while your phone is on 2.4 GHz.
Incorrect Wi‑Fi password or special characters cause errors
- Verify the Wi‑Fi password on another device and type it manually in the app.
- Re-enter the password carefully, watching for capitalization and symbols.
- If possible, test briefly with a simpler password as a diagnostic, then restore the original.
Weak signal or heavy Wi‑Fi interference at the robot
- Move the robot and dock closer to the router for setup (a few metres).
- Turn off devices that may cause interference (microwaves, wireless cameras) during setup.
- Retry setup with the robot closer to the router.
Router blocks new devices (guest network or device filtering)
- Ensure you are using the main Wi‑Fi network and not a guest network that restricts devices.
- Temporarily disable MAC filtering or parental controls, or add the Roomba if you can.
- Repeat the app setup after adjusting router settings.
Factory reset
Warning: a factory reset erases Wi‑Fi settings, scheduled cleans and your account pairing; you will need to set the robot up again in the app.
- First try 'Forget device' or 'Reset' from the robot settings in the iRobot Home app if available.
- If the app does not provide that option: power the robot on and press and hold the Home and Spot buttons together (or use the method in the user manual) until the robot signals a reset.
- Place the robot back on the dock and add it again in the iRobot Home app following the first-time setup flow.
Frequently asked
Does the Roomba i5 work on 5 GHz Wi‑Fi?
Most Roomba i5 models require 2.4 GHz Wi‑Fi; use the 2.4 GHz network during setup.
The app shows 'robot offline' — what should I check first?
Check your router and internet connection, reboot the router if needed, and ensure the dock is within good Wi‑Fi range.
Will a reset remove my maps and schedules?
Yes — factory reset removes saved maps and cleaning schedules; note any important settings before resetting.
How do I know the robot is in pairing mode?
It typically makes a sound or shows a light pattern; the iRobot Home app also guides you through confirming pairing mode.
