Am not having any issues like that at all here, so possibly not related to the router?Same here, randomly. Can't access wifi when this happens. Via Ethernet I can and it only says no internet. Reboot is the only thing that can fix the problem. Really annoying, I have sent Asus logs, I have sent mail to customer service. They just want me to reset it. I have already... does not fix it.
WAN has been solid with no dropped connections.
