i did access the router settings page and looked at all of the devices that are connected and its not listed.
when i unplug the ethernet cable from the A3 it makes so fan adjustments and when i reconnect it - seems to "power" up again
so it seems like there is a signal/connection with the ethernet cable
When I setup my device.. Window Edge didn't let me in.. I download Opera Browser and was able. Check you router for any lan connected mine didn't show Antmine it was lan connected port 192.168.1.168
Hope that help. just check any lan connect port. if you can't login in root root get a different browser .. Edge sucks.
