Armbian on RockPi S - hotspot


I am testing the Armbian config to create a hotspot - and am using an external USB wifi as the “uplink” and the native WLAN0 as the hotspot.
Two issues:

  1. After a while the uplink and hotspot components seem to stop passing traffic between them. I can still remotely access the device via the “uplink”. Any one have any ideas as to why this could happen ? Some sort of buffer over flow ?
  2. When rebuilding the Hotspot - as in deleting and starting again - the build goes to 90% but then losses “uplink” and I can no longer access the device. Any one have any ideas ?

(Update: I suspect this loss of uplink might have something to do with the probing of the hotspot during setup - knocking the link off air)
