Running 9.8. on my ZD 1100. The portal where an employee can type in their u/n and pw does not work in Chrome or on an Android phone we tried. It accepts the u/n and pw, but then just blinks and returns to that same login page. No file is downloaded.
The problem is the with the HotSpot service - I had this too. Raised a support ticket and Ruckus Tech logged in remotely and made some changes and achieved same functionality. Not sure if the original problem has been fixed though - but Ruckus know about this and they know how to workaround it too!
