Just installed Ubuntu 16.04 on an Acer Aspire S and everything's working great except the wifi. I can connect to open hotspots, but when I authenticate to my WPA2 router at home it fails.
This is with an Atheros QCA6174...

Never had any problem with connecting with my other Ubuntu systems. Here's the modprob...

Seems it authenticates successfully but then deauthenticates right after? Tried replacing my /lib/firmware/ath10k as mentioned in https://askubuntu.com/a/718430/717711 but that caused my wireless to stop working entirely so reverted those changes.
Unfortunately I'm now a bit stumped. Help appreciated!
