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> [1715810843.0128] device (wlp0s20f3): Activation: failed for connection 'apex-uploader'
