I've been trying to connect my SL 16.4.2 AI mixer to an iPad, using both SL-Remote AI and UC Surface, and it's given me the "Limited to No Connectivity" error on both of them. They're on the same wi-fi network, and it shows up on my list of devices in both apps. The iPad also does not show up on the board as a device to which I can grant permissions.
I know the firmware is extremely out of date, but we never had problems with it until recently. I don't think anything's been updated or changed...just stopped working. I've attempted to update the firmware and such but we purchased the mixer quite awhile ago and tracking down the info in order to register it and download the new firmware has proven to be a bit of a challenge. (If there's some way I can update the firmware without needing to register the device, that would be extremely helpful.)
Any ideas as to what might be going on? Running SL-Remote AI 1.2.1 and UC Surface 184.108.40.206030, and firmware version 1.0.4834.
