I moved our desktop away from the gateway upstairs into the wifi extender range downstairs. There is no internet connection. I tap the extended wifi for automatic connect, but it asks for a security pass word. Where do I find this? The extended wifi works on all of our phones and tablets, but not on desktop. Help!
If you are using a Comcast supplied gateway device, and if it hasn't been changed from its default value, it is on a label on the bottom, back, or the side. It may be called the "Password" or the "Network Key" on that label.
