I'm sorry about the issue. What kind of icon is it? Does it happen when you open the Google Chrome app?
What's the model of your Acer Chromebook, such as C720, or CB3-11, etc.?
When you go to the Wi-Fi / wireless icon / option on the printer, what happens when you select / connect to your wi-fi/wireless network name?
Please reply at the box below. Thank you.
