Yes, it has worked before. The problem is that firefox (at least,
likely other apps too) starts in "offline" mode unless it detects
NetworkManager in some way as being active.

Yes, tried this several times, and multiple variations of disabling
the "network" service then enabling it, starting and restarting it,
combined with enabling and disabling NetworkManager service and
stopping and restarting it.

It's some combination of those services working together that causes
this to work, and apparently only that specific combination, afaik.

Does anyone know how udev works with all this, and persistent connections?

Thanks,
