Since I have the same Wifi chipset (AR9271), I installed the latest updates
to see. Here is the related entry in /var/log/apt/history.log:

NetworkManager is updated (nothing specific to Atheros chipsets) and things
go wrong indeed. In the case of my system, wronger than what Piriponzolo
reports: after restarting NetworkManager (or rebooting the whole system), I
apparently can neither get a Wifi connection nor a wired connection. The
version of the kernel does not seem to make a difference. I tried versions
4.4.0-161 and 4.15.0-55, Trisquel's default and HWE versions.
I wrote "apparently" because the wired connection works with IP addresses.
As far as I understand (I am not knowledgeable when it comes to networks),
the DNS servers of my ISP are not automatically set anymore (since the
update). I have actually always wanted to use the DNS Of French Data Network
(a French associative ISP, fighting against censorship) and adding
80.67.169.12 in the DNS tab of the Network Settings works. So, here is a way
to get a working wired connection... but the change is not persistent (it has
always been like that on my system, for some reason): the DNS must be
The Wifi problem seems unrelated and more serious. Right after plugging in
my adapter, here are dmesg's messages over 114 seconds (I removed the
timestamps to ease the reading):
