Atualmente, minha rede sem fio parece não querer funcionar para mim e parece que tenho um driver ativo listado ao executar o comando lshw;
zero@zero-Lenovo-Z50-75:~$ sudo lshw -C network
*-network
description: Network controller
product: QCA6164 802.11ac Wireless Network Adapter
vendor: Qualcomm Atheros
physical id: 0
bus info: pci@0000:02:00.0
version: 20
width: 64 bits
clock: 33MHz
capabilities: pm msi pciexpress bus_master cap_list
configuration: driver=ath10k_pci latency=0
resources: irq:35 memory:f0800000-f09fffff
E tudo parece bem a partir do que posso dizer ao executar comandos lspci e lsmod
zero@zero-Lenovo-Z50-75:~$ lspci | grep Network
02:00.0 Network controller: Qualcomm Atheros QCA6164 802.11ac Wireless Network Adapter (rev 20)
.
zero@zero-Lenovo-Z50-75:~$ lsmod | grep ath

Eu também coloquei um pouco mais de informação
zero@zero-Lenovo-Z50-75:~$ lspci -nnk | grep 0280 -A2

4.4.0-21-generic
Estou usando uma versão recém-instalada do 16.04 e passei pelo guia de solução de problemas sem fio, link , sem sucesso real, mas foi capaz de, pelo menos, retirar essa informação. Alguém tem alguma ideia de como posso fazer com que a conexão sem fio funcione neste dispositivo?
UPDATE

Desculpe pelo atraso no lançamento, demorei um pouco para chegar a uma conexão linha-dura. Eu corri através dos comandos recomendados para atualizar os drivers ath10k e temos decolar. Atualmente estou conectado via WiFi sem problemas até o momento. Vou tentar acompanhar isso depois de 72 horas ou mais de uso.
