Last night I discovered that someone unplugged the xfinity box. I plugged it back up and it seemed fine. The WiFi is connected but it says no internet access. It says this on the laptop as well as a Samsung tablet. It shows full bars but there is no internet access. The main plug that goes into the wall was unplugged from the xfinity box. And the net gear router was turned off. I don't know much about electronics so please forgive the improper terms.
