Public bug reported:
I installed 24.04 on a Raspberry Pi 4b (8 GB). In addition to the built-in NIC,
I have a Netgear USB A8000 NIC installed. When I turn on the Hotspot for the
internal NIC, NetworkManager creates and activates the connection. However,
when I try to connect to the hotspot from a different machine (Windows,
Ubuntu), the connection does not succeed. The connection machine reports:
2024-05-15T18:07:23.013534-04:00 moose-Oryx-Pro NetworkManager[949]: <warn>

I've tried various remedies obtained from Googling but none change this
behavior. I have tried this on both 24.04 server and desktop. Hotspot
does work on the same machine with Pi OS Bookworm.
