Hello,
Just recently I noticed I have really slow Wifi on my MacBook Pro 13" Mid 2012. Half of what my iPad and iPhone 5. I looked at my data rates under the Airport Utility and my MacBook showed a data rate of 14Mbps while the iPhone and iPad showed 65mbps and 150mbps. I am using an Airport Express updated to latest firmware and am sitting right next to the router.
