Can't access Airport Extreme after Yosemite install.
I can't access my airport extreme in finder after installing Yosemite.
I have a portable HDD connected to it, and I could access files from it before installing Yosemite.
Trying to access from a brand new Macbook Pro Retina and a Macbook Air mid 2013, both with Yosemite installed.
The Airport extreme is the latest model with version # 7.3.3
When trying to connect in (with password) finder I get a message saying that the version of the server I am trying to connect to is not supported, contact the system administrator.
I tried resetting the router, and setting up a new network, but same results.
Hope someone can help, thanks.
MacBook Pro (Retina, 13-inch, Mid 2014), OS X Yosemite (10.10)
