Had to have the power turned off for approx 1 hour this morning. When back on the router fired up OK. Internet is fine on the ethernet cable. Guest Wifi works fine. Main Wifi that every appliance and device is connected to is not working. Also when you try to connect to the main Wifi on my iphone is says unerneath "Weak Securty" while trying to connect. When is is connected in orange letters i just get "No Internet Connection"
