I have a new service with Xfinity and the Gateway Modem/router. When I try to connect my printer or other devices, it asks for the Network Security Key? I have troed every number and combination on the Router, but it will NOT accept any of them?? Does anyone know where to find this??
The Network Security Key is just your WiFi password.
If it hasn't been changed from its default value, yes it is on the label on the bottom, back, or the side. It may be called the "Password" or the "Network Key" on that label. Are you typing it in exactly ? CAPS or no caps makes a difference.
Before troubleshooting gets too exotic, you need to go be sure the router is set to defaults. If someone used the unit before you they may have changed the password.There is a recessed button on back of the unit, hold it down for 10 to 15 seconds, release and let the unit reboot. Try your connection after this.
