Didn't work as well as the card I already had.

Mi Problema

Apple diagnostics told me that my wifi card did not pass their specs and wanted $310 to fix it.

Mi Solución

The installation went fine. Instructions were great. But i ran a speed test before and after and i was getting significantly slower speeds with the new airport card. I put the old one back in and got faster speeds. Put the new one back in, got slower speeds. Put the old one back in, got faster speeds and left it.

Mi Consejo

Card didn't seem to help this issue at all. Not sure if it was me doing something wrong but I doubt it.
