IWD as in Fedora NetworkManager doesn't restart/start/stop the IWD
service (I understand that in Arch Linux NetworkManager does).

The restarting of the NetworkManager and IWD services caused
NetworkManager to create an new wifi definition rather than use the one
I created, with the auto-created definition using WLAN2.
Your network device name will be something like "/dev/enp0s20f0u4",
where the number of the USB port is part of that sequence.  If you use
a different port, it's seen as a different device.

It's not that intuitive.  We expect a device name to be associated with
the device.  Which is doable with some jiggery pokery, but it's far
easier to just keep dongles plugged into the same port.

To put that into context.  We expect our mouse to always been seen as
our mouse, no matter which port we plug it into.

I came across this when I recently unplugged my phone cable from the
computer, and didn't plug it back into the same port.  The cable had
been in the same port for months, and I hadn't really thought about it.


With the dongle being a USB3 device I switched it back to a USB3 port because I hadn't realised that when I moved it to see if the continual connect/disconnect issue changed, which it didn't, but I was expecting to see the wlan* device being renamed to a name like the one you supplied, as I had seen that happening in the journalctl output, but from what I could see that didn't happen in this case, but I have an even bigger problem now, the kernel driver required for the dongle is now erroring at boot time. I raised a mail on this but I can't tell if it made the list as I forgot to CC myself on it so it wasn't echoed back to me and replies I do get echoed back without a CC and as yet there haven't been any responses to the mail if it did make the list. This failure may be because of IWD options I've specified but I don't know.
