Airport says its not installed after reassembly

I disassembled my MacBook Pro to clean and re-apply thermal paste due to its over heating. After I reassembled it, I get a "Airport not installed" after booting up. I tried reinstalling the OS, SMC and PRAM reset and those didnt work. Did I not get a wire/cable connected properly? Does anyone know which connection on the logic board I need to reseat? I didnt touch the Airport card until I had this problem, I tried reseating it too. Thanks for your help!
