Fellas, I noticed today, while finally getting to use the Fedora
side of my work laptop, that my wifi is running at 1MB/s on d Dell
XPS 13 9550. According to Dell this model has the Killer AC 1535
wireless chipset so possibly just a driver issue?

Just relative to this issue, I am using a driver I have compiled myself
because there is no native support for my wireless adapter (DWA192). On
the 5GHz channel I am getting a bit rate of 1.3 Gb/s with a link quality
of 88/100, which is what that channel is rated at, but on the 2.4 GHz
channel I only get 217.6 Mb/s with a link quality of 91/100, even
though this channel is rated at 600 Mb/s. Under Windows 10 I get a bit
rate of 525 Mb/s on the 2.4 Ghz channel (the 5 GHz channel gets 1.3 Gb/s
as well). Is the poor bit rate on the 2.4 GHz channel (I'm on F25) an
issue with the driver or some other aspect of the environment?

Steve

(Yes I know Mint.. the results for later version of Fedora were
severely lacking)
Whats odd is that I Put F25 on the wifes Lenovo just Sunday night to
resolve this exact issue.
Thanks!
I think my issue is an incorrect or missing firmware:

I have cloned the kvalo git and have teh files staged for copying later.
It's interesting that it's looking for the firmware-5.bin file in
the hw3.0 directory, as it doesn't exist there. It DOES exist in the
hw2.1 directory (at least on my F25 system):

Perhaps a simple copy to the 3.0 directory would satisfy it.
