Hello Ron,
I opened a ticket according this issue and I got a quick answer:
"...for now and the foreseeable future, access WM via Console will be necessary for creation of AP groups..."
In the moment there is no fix roadmap to replace the Wireless Manager (Java) by a Extreme Managment function.
My 3805 Access Point (without ROW) works fine with the WM (as AP38xx).
As result from my ticket, if your 3805-ROW don't work with WM, you have to create a ticket for this issue.
Regards
Stephan
