Sorry, in advance for my limited tech knowledge. We had been using an Apple Airport for wifi connectivity and to print using a non wireless printer. But our Comcast Cable Modem died and they sent us home with a new Comcast Infinity Modem/Wifi device. We unplugged the Airport and hooked up the Infinity and have Wifi but now we can't print. Is it possible to set the Airport up in conjunction with the Infinity and then have printing capabilities? Or must we invest in a Wireless Printer? We have a MacBook and a PC which share this printer. Thank you for any insight you can give us.
