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.
It could be something like that, except the math doesn't work. Stephen
is saying that he gets 450 Mb/sec at 2.4 GHz in W10, and 252 Mb/sec at
2.4 GHz in F26(?). That's only a factor of ~2.
And the 5 GHz is 450 Mb/sec in F26, but 1.3 Mb/sec (Gb/sec?) in W10.
If it's GHz, ~3.
Sorry, I did mistype the speed, it was actually 1.3 Gb/sec under windows.
These are all reported / theoretical speeds rather than measured
speeds. What matters is how fast the bits move when doing a real task.
I don't know where he lives (Australia?), but I think 1300 Mb/sec is
faster than most real world networks support, though Japan and Korea
might be approaching that. Even 450 Mb/ sec is a respectable speed.
The average speed in the US, last article I saw, was around 250
Mb/sec, though high speed connections are available at around 1000
Mb/sec.
The connection speed being reported is the speed between the pc and the
router over the wireless interface.
I am in Australia. The router is rated at 600 Mb/s on the 2.4 GHz
interface and 1300 Mb/s on the 5 GHz interface to give it the connection
speed of 1900 Mb/s AC. As I mentioned above under Windows I get 452 Mb/s
and 1300 Mb/s respectively so I was expecting similar connection speeds
under Linux.

Steve
