MacOS clients sporadically disconnect from WPA Enterprise wireless network
This is a well known bug in a mac, but they fixed that a few months ago. If you have the latest update check the router instead or buy a cheap router. Select extender mode when setting it up, then once set up change the name of the extender so its some sort of bridge to the current network. That way, when you connect to it the router keeps redirecting your connection to the enterprise network.
