I had this issue, and you need to update to the latest firmware on the clearstream. On mine it took like 4 or 5 tries of hitting the firmware update button for it to actually update.
When it would not update, it would reboot and then back to defaults.
When it worked correctly, it would reboot, go back to defaults, but when I connected to its wifi, it would say “Updating” for around 5 minutes. That is when it was actually updating.
