Acer C720 3404, Unable to login: No Internet connection error message

WiFi and Wired connection show connected. Cannot login to 720 as usual. No Internet connection message prevents logging in. I renewed ChromeOS with no change. Disabled WiFi and rebooted no change. I suspect m-board not working. My User login has warning sign that brings up Internet error message.

I have same error at several WiFi signals where I seemed to connect fine except for login error. I can login to these WiFi signals with other devices. Before this 720 login issue, I logged into WiFi fine.
