Can you update the app or website to display the latest firmware release information for this device? When I plug in my hub, it only shows the current firmware version on the device but doesn't indicate if it's the latest. Unlike other options, I can't click on the box for more details. Additionally, I couldn't find any information on your website about the current firmware version or its release notes.

So is there a direct replacement upgrade to get ac on the mid 2012 MBA, can someone point me to a guide or somewhere that has posted knowledge about this?
