    Wireless problem

    Hey guys,

    I have an Acer Aspire 5515 laptop with an internal wireless card. (802.11abg)

    When I boot up in Vista, I can connect to my network automatically.

    When I boot up in Ubuntu, I can't access the wireless capabilities.

    How do I connect to a wireless network?

    Have you tried going to:
    System>>Administration>>Hardware Drivers
    and checking if there are proprieatary drivers, and if so, enabling them?
    Kipling - "if"

    Did what you said, and it came up with this:

    Component Enabled Status
    Atheros Hardware Access Layer (HAL) (enabled) In use
    Support for Atheros 802.11 wireless LAN cards (enabled) In use

    I have already tried ndiswrapper and it didn't work.

    Re: Wireless problem

    I am having the exact same issue with the Acer Aspire 5515. What's really puzzling is that Acer doesn't have this computer listed at all on their Support site! I suspect that is because this is a brand-new model Acer just put out a couple weeks ago -- everything posted about the Aspire 5515 on the Internet is from the last 7-10 days.

    Here's my output for various commands

    lspci:
    Code:
    (...)
    02:00.0 Ethernet controller: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01)
    05:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 02)

    ifconfig:
    Code:
    eth0      (ethernet...)
    
    lo        (...)
    iwconfig:
    Code:
    lo        no wireless extensions.
    
    eth0      no wireless extensions.
    
    pan0      no wireless extensions.
    lsmod and dmesg both contain no information about wireless. This is clearly a driver issue but I have no idea how to solve it. Anyone got an idea? I am going to open a bug for this.

    Re: Wireless problem

    I am DELIGHTED to report a solution to this problem.

    First I installed the backported ath5k drivers. To do this, do the following (from here)
    1) System->admin->"Software Sources"
    2) On "Updates" tab check "Unsupported updates (intrepid-backports)"
    3) When prompted click "Reload" to update the indexes
    4) System->admin->"Synaptic..."
    5) Find and mark for installation "linux-backports-modules-intrepid"
    6) Click "Apply"
    7) optionally from Terminal type "modprobe -l | grep ath5k" and you should see the location of the driver displayed to confirm it is there.
    At this point if you reboot, your wireless may work. Mine didn't, so I had to open /etc/modprobe.d/madwifi and comment out the line "blacklist ath5k".

    If this doesn't work for you, read the whole ath5k instructions here. But this worked for me.
