Hub failed connecting to internet so I unplugged it and reconnect it again but right three seconds green light disappeared when it was flashing. I ́ve reset it and nothing, I ́ve changed ethernet cables and no go either even though the blue light is steady...any ideas?
I just had the same issue, which led me to this page. I have my hub connected to a WiFi extender. My WiFi extender had connection, but not my Chamberlain hub. I fixed the issue by unplugging my WiFi extender for 30 seconds and plugging it back in. My Chamberlain hub reconnected about 2-3 minutes later. Hope this helps.
