apple modem with build-in wi fi
My Comcast service is a triple play --includes TV: Land Ph Line , and Internet . The old Comcast router has failed -unable to connect using wi fi to apple tv or to my Mac pro laptop. works ok using ethernet for the Mac. Understand there is a comcast "gateway modem with build-in wi fi . which I can exchange for free. However why pay extra monthly rent for this --rather like to just buy a reliable Apple replacement and own it. Now big Q-my other computer is a windows vista ,is there a apple modem with build-in wi-fi or even a apple modem with separate router replacement that can also handle what I have which is a Mac Pro, Windows Vsta Computes and a Apple TV and a Phone landline, like my present Comcast modem/router did? Please advice.
Mac Pro, Mac OS 8.6 or Earlier, windows vista desktop
