Ubuntu 15.10 server wifi and Atheros AR9287

I have в server I am trying to get wifi working on... it cannot be wired due to the location it needs to be in. I bought an TP-Link TL-WN881ND for it seeing that it had the same chipset (Куальком Атерос AR9287) which I saw on thinkpenguin (bought the TP-Link from Amazon for quick shipping)... anyway, it connects to my WPA2 wifi network, but I cannot ping the router, resolve dns internally or externally. It is using the following драйвер:

ath9k

I have tried anything that made sense when googling, including adding the following:

echo "options ath9k nohwcrypt=1" > /etc/modprobe.d/ath9k.conf

but не change. I have installed the full ubuntu gnome desktop to try anything to get it working... when trying путь command line before installing desktop, I attempted to get it working путь wpa_supplicant, but it would hang after issuing the following:

wpa_supplicant -iwlp3s0 -c/etc/wpa_supplicant.conf -Dwext

which I guess is в generic wireless драйвер... ath9k was never listed there, just nl80211. гm not finding anything on 15.10 and the ath9k issue. Anyone able to help?

EDIT: I am able to run в temporary ethernet кабель to try stuff... it's just... temporary :(
