Network key
Updated my mid 2009 MacBook Pro OS to Version 10.10.3 Yosemite. I Recently moved and have a new internet provider (Comcast) and purchased my own modem (Motorola Surfboard) Everything is operating as it should. I am having a problem getting a new Brother printer connected wirelessly. As part of the setup the network key is needed. I tried every possible way to locate that info and I am still coming up empty. I am using a AirPort Extreme router. Any suggestions?
