I have enabled Internet Sharing to "Share your connection from: Airport" and share "To computers using: Built-in Ethernet". I currently receive my wireless signal from another part of the house and need to share my connection to my XBox 360 as well as my Blu-Ray player and DVR. When I connect my router to my iMac via Ethernet, it does not connect to the Internet. Does anybody know what might be wrong and how I can fix this? All help is appreciated!
