    [SOLVED] Acer Aspire 7551G-7606/Kubuntu 10.04/Wireless Issue

    I am having trouble enabling the wireless network card. Per the instructions on how to submit this type of problem I have entered in all the relevant information below.

    1) Machine Brand and Model
    Code:
    Acer Aspire 7551G-7606 Laptop
    2) Wireless Brand, Model and Wireless Chipset
    Code:
    06:00.0 Network controller: Atheros Communications Inc. AR9287 Wireless Network Adapter (rev 01)
            Subsystem: Foxconn International, Inc. Device e034
            Flags: bus master, fast devsel, latency 0, IRQ 17
            Memory at d0200000 (64-bit, non-prefetchable) [size=64K]
            Capabilities: <access denied>
            Kernel driver in use: ath9k
            Kernel modules: ath9k
    3) Check Interface
    Code:
    wlan0     IEEE 802.11bgn  ESSID:off/any  
              Mode:Managed  Access Point: Not-Associated   Tx-Power=off   
              Retry  long limit:7   RTS thr:off   Fragment thr:off
              Power Management:on
    Check for modules: (Sorry about the long output here but I don't know what to look for on this one.)

    5) Kernel Boot Messages
    Couldn't find any information on wlan or wireless. If you can tell me what to look for I'll put it here but this list was entirely too long.

    Network Configuration
    Code:
      *-network DISABLED

    7) Scan For Networks:

    wlan0     Failed to read scan data : Network is down
    8) Ubuntu Version:
    Code:
    Description:    Ubuntu 10.04.4 LTS
    9) Kernel/Architecture:

                                                                                                 [ OK ]

    Below are some additional commands.
    Code:
    ricomoss@keaton:~$ nm-tool

    and...

    Code:
    ricomoss@keaton:~$ sudo rfkill list

            Hard blocked: no
    1: phy0: Wireless LAN
            Soft blocked: no
            Hard blocked: yes
    It appears to be blocked.

    Any suggestions?
