Ubuntu: Wireless not working with an Atheros AR9285



Question:

I recently installed Ubuntu 12.04 and found my wireless card is not detected by OS. I tired to detect it by network manager but still it is not get

output of the required command:

toor@Linux:~$ sudo lshw -class network    *-network                        description: Ethernet interface         product: AR8131 Gigabit Ethernet         vendor: Atheros Communications Inc.         physical id: 0         bus info: pci@0000:03:00.0         logical name: eth0         version: c0         serial: f0:de:f1:9e:22:4d         size: 100Mbit/s         capacity: 1Gbit/s         width: 64 bits         clock: 33MHz         capabilities: pm msi pciexpress vpd bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt-fd autonegotiation         configuration: autonegotiation=on broadcast=yes driver=atl1c driverversion=1.0.1.0-NAPI duplex=full firmware=N/A ip=124.123.227.84 latency=0 link=yes multicast=yes port=twisted pair speed=100Mbit/s         resources: irq:44 memory:f2400000-f243ffff ioport:2000(size=128)    *-network UNCLAIMED         description: Network controller         product: AR9285 Wireless Network Adapter (PCI-Express)         vendor: Atheros Communications Inc.         physical id: 0         bus info: pci@0000:04:00.0         version: 01         width: 64 bits         clock: 33MHz         capabilities: pm msi pciexpress bus_master cap_list         configuration: latency=0         resources: memory:f2500000-f250ffff    and   toor@Linux:~$ rfkill list all  0: ideapad_wlan: Wireless LAN      Soft blocked: yes      Hard blocked: no  1: ideapad_bluetooth: Bluetooth      Soft blocked: yes      Hard blocked: no  

Please let me know what more info is required to resolve it.


Solution:1

Your problem is two-fold and you'll have to handle both errors.

  • *-network UNCLAIMED means no kernel module (driver) is taking care of this piece of hardware.

    For your device, I'd recommend first to see if there are drivers available using the regular method: How do I install additional drivers?

    In case that doesn't list any drivers for your device, try installing backported drivers from newer Linux kernels. Ubuntu has packages available for these so-called compat-wireless set of drivers. See my answer in another related question on how to do this.

  • ideapad_wlan: Wireless LAN, Soft blocked: yes means that your radio kill switch is activated. This prevents all communication and is useful in case you intend to do so (e.g. when requested in an airplane). To enable your radio, disable this killswitch by issuing

    sudo rfkill unblock all  

    to enable both WiFi and Bluetooth in your case.

See My WiFi adapter is not working at all, how to troubleshoot? for a more general, complete how-to.


Solution:2

you can get your wireless drivers by looking at additional driver details and downloading them respectively. Since you have not provided me any details of your wireless adapters and PC spes, I could not help you more on this right now.


Solution:3

I have a laptop with the same wireless card and it worked out of the box.

However, I realised that if, while on windows I disable the wifi, I'm not able to enable it on Ubuntu. Booting Windows, enabling wifi and rebooting solves the issue.

If you are not dual-booting, try entering the Bios setup, find the wifi card and enable it if necessary.


Solution:4

Why don't you try to install the drivers for your wireless card?

  1. Download this drivers: compat-wireless-3.6.8-1.tar.bz2
  2. Install the drivers:

    tar -xf /path/to/compat-wireless-3.6.8-1.tar.bz2  cd /path/to/compat-wireless-3.6.8-1  ./scripts/driver-select ath9k  make  sudo make install  
  3. Reboot your computer.

If this doesn't work let me know.
