OK -- I have no clue what my issue could be and am starting to get a bit
frustrated with this WiFi chip because it seems like there's nothing I
can do about it. I'm using the Ath10k QCA6174 chipset on a Acer Aspire V
Nitro laptop. Every other device I have connects at a much faster rate
to my Asus AC66U WiFi router, but for the life of me I cannot get my
laptop to connect to it at a rate over 1Mb/s, according to iwconfig and
the nm-applet tool.
I also cannot connect to the 5gz band on the router either, while all my
other devices have no issues. When I got the laptop I was able to
connect to either 2.4 or 5.0 bands in Win10, but since I've installed
Ubuntu it's been hopeless and I've tried just about every solution out
there. Granted, when I first got the laptop getting this chip to connect
to anything WiFi was pretty much a lost cause, and I know that the
driver for it has come a long way, but there are still several issues
with it that's really degrading the potential of the hardware.
Even on the 2.4ghz band, the only one I'm able to connect to I'm having
severe degradation of service and it sometimes won't even connect to the
access point and crashes nm-applet. Can someone please explain why it is
that it's showing only a 1Mb/s bit rate and why I'm unable to connect to
the 5ghz band on the router?

Here is dmesg when I'm attempting to connect to the 5ghz band:

Pardon spreading my frustration but I really don't like Windows and I really
don't want to succumb to using it for this reason, if all else fails I may just
try to replace the chip with a different one.
