Due to a hardware limitation, the blue and purple LEDs on your Arlo Baby might be difficult to distinguish.
If your Arlo Baby is connected to your WiFi network but has a poor connection to your router, the LED blinks purple. If you see what looks like a blinking blue LED but your Arlo Baby is already connected to your WiFi network, the LED is likely blinking purple, not blue.
