Hi Paul, I need to find out how to align your account in the system with your company so you can browse the downloads.
Extreme Networks SummitWM software is available in the new portal, but the "Moto/Zebra" WiNG software isn't. Even on the Extranet page, 5.2.x isn't available.
If you need "old" software, you'll need to contact support so it can be provided to you directly.
