Problems with Qualcomm Atheros AR9285 Wireless Network Adapter

Question

Here is my problem:

lspci:

01:00.0 Network controller: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) (rev 01)

lshw -C network

*-network  DISPONIBLE  

   descrição: Interface sem fio
   produto: AR9285 Wireless Network Adapter (PCI-Express)
   fabricante: Qualcomm Atheros
   ID físico: 0
   informações do barramento: pci@0000:01:00.0
   versão: 01
   serial: 1c:c6:3c:ce:49:e3
   largura: 64 bits
   clock: 33MHz
   capacidades: pm msi pciexpress bus_master cap_list ethernet physical wireless

Note that the wireless interface has no logic name. So, after this step nothing works with wireless connection.

I am running kubuntu 14.04.2 lts

Solution

Let's get the driver to load automatically on boot. Open a terminal and do:

sudo -i
echo ath9k  >>  /etc/modules
exit

Reboot. Check:

iwconfig
dmesg | grep ath

Does it get a logical name, ideally wlan0, if you load the driver? sudo modprobe ath9k Welcome to askubuntu.

Thank you. No. Load the driver don't get a logical name to device. The problem is on the boot. If get a logical name on the boot, the device run fine. If don't get a logical name on the boot, nothing works.

I'm having the same problem with the same hardware. Have you ever solved this?

[Gilberto André Borges]

I prefer to observe what will happen in the coming days. If driver run fine or not with the new kernel. I will coment here. Thank you.

Important to coment: the computer is new. I bought a month ago, AMD kabini. I think the hardware it's ok.
