Yeah, OK, that's pretty sucky. So it does look like it's the driver
or firmware or some setting on the interface that's limiting the speed.
I guess you could try "iw dev wlan0 link" to see what speed it thinks
it's running at and "iw dev wlan0 scan dump" to see more details

, but
I don't know what else to try. Are you using any special
hardware
drivers (e.g. nVidia binaries, etc.)? They might have an effect.
No out of tree modules, this is stock Fedora 25 from a clean
installation, not an upgrade. The main differences from default is
Btrfs for root and home, and frequently using Rawhide kernels for
testing.
