      Having downloaded an updated version of the driver from Github
that now compiles and runs with the 4.13 kernel I have looked at the
wifi properties under Gnome and they tell me the connection speed is
450Mb/sec which is about the connection speed I get under Windows 10
with the 2.4 GHz interface. Under Windows 10 the 5 GHz interface
connects at the documented speed of 1.3 Mb/sec. If I use the 2.4 GHz
interface for the device gnome tells me the connection speed is 252
Mb/sec.

      Why are the connection speeds in Fedora so degraded?
I don't have an answer to your question, just a suggestion.  What speed
do you actually get when you test it?  If the real life speed rather
than the reported speed is different, then it is time to investigate
why.  If there is a real life discrepancy, then it could be that the
firmware in linux is reverse engineered versus the custom tuned
firmware for windows written by the manufacturer.

Not sure if this will work for you, but there should be one you can use
somewhere on the web.

Is one of them reporting in "MB", and the other in "Mb" ?? the
former is megaBYTES, the latter is megaBITS. They differ by roughly
a factor of ten.

I've just checked Gnome again on the 5 GHz link and it is showing the connection speed as 450 Mb/s, which is in Megabits, if it was megabytes then that would equate to 3600 Megabits/sec, which the router is not capable of.
