Check Your Internet Connection:

Check Your Internet Connection

You need to check your internet connection if rebooting doesn’t help. A weak or unstable connection could easily cause an error code 15. 

A bad connection is likely the cause of connection problems with other connected devices in your home or if your router’s indicator lights aren’t lighting properly. 

A weak WiFi signal may be in specific areas where the robot operates, causing Roomba Error 15. A WiFi signal improvement can resolve the problem in such spots.

Reboot both the robot and the WiFi router. You can reboot your WiFi router by unplugging it for 30 seconds and then replugging it.

It is recommended that you connect the iRobot to the 2.4 GHz band of your router if your router supports dual-band connectivity. If your router does not, communication may fail with the iRobot. The error can be resolved by making sure the frequency band is correct.
