You can try the following two options:
- Disable Pre-association / Scanning random MAC address;
OR
- Switch to one of the modern version of the driver,
r92su is easier to set up because it uses the same firmware as r8712u;
Thank you, poma. Your answer is spot-on.
Your first suggestion attempts to push me into the swamp of
understanding the NetworkManager. As a senior member of this august
brotherhood, I do not have enough days left to undertake this
challenge. I'm afraid I cannot and will not attempt to make sense of
the "logic" represented there.
Your second suggestion - build and use r92su instead of r8712u -
works perfectly. I measured bandwidth of only 28.4 Mbit/sec compared
with your ~82 Mbit/sec, but I'll leave that curiosity for another day.
This raises a number of ancillary questions:
1 - How did you discover the existence of this newer r92su driver, and
where to find it?
2 - Are there others, hidden from mere mortals, for other devices?
3 - Was Fedora 25 knowingly released with broken drivers when better
ones are available for those privileged to be aware of them?
4 - Why, exactly, has the r8712u driver become broken? It has worked
perfectly through F24.
5 - Was any of this announced? Will it be?
poma, thank you again for your helpful information. I enjoy reading
your comments. They're always helpful, although sometimes so concise
as to be incomprehensible. This one was clear and complete.
