Hi Gary,
Thanks for the question. Are you using the 791's with an SA-5 amplifier? If so, you can use Bluetooth to the SA5 to play audio to the speakers. The method of using a wireless hotspot, while not technically supported by Bose, may work for you.
If you have any further questions, please let us know.
Best Regards,
Brandon
Hi Gary,
Do you have the SA-5 setup on the hotspot? From there you can get into the Bluetooth settings on the SoundTouch app and make the system discoverable, which can then be seen by your phone.
Thanks,
Brandon
