I am trying to set up the port forwarding. I enter the details i wan and then hit save and all i get is the box asking for the username and password. I f i enter them it just flashes up again then after 3 attempts a red page comes up saying 401 Authorization Required You are not authorized to access this device. Either you supplied the wrong credentials(e.g., bad password), or your browser doesn't understand how to supply the credentials required Does anyone know what is going on? I tried to reflash the firmware and it keeps failing, says this page cant be displayed and i have to turn gateway off and back on to access it again, what can i do?
