    wireless card not detected on acer laptop

    Hi Everybody.

    I am a newbee on using unbuntu. I like it but when something isn't working right away I get lost.
    I have a new laptop : Acer Aspire 5720Z-3A3G16Mi
    with a wireless card: Broadcom Corporation 802.11g Giga bit.

    It is not working when I have installed ubuntu 8.04 (Hardy). I tried all the Terminal commands described in the troubleshoot section but it seems that is doesn't recognize the wireless card at all. No output or anything.

    Does somebody knows this problem?

    Can you post output of the following:
    Code:
    lspci
    Code:
    iwconfig
    Code:
    iwlist scan
    You came empty handed, that is how you shall leave. Whatever you claim as yours today, belonged to someone else yesterday, will be someone else's tomorrow.

    I'm not the original poster but I have the same problem with a reconditioned Acer Aspire 4520 that I pulled out of the box and loaded Hardy on last night.

    lspci = 07:00.0 Ethernet controller: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01)

    iwconfig =
    llo no wireless extensions.
    eth0 no wireless extensions.

    iwlist scan
    lo Interface doesn't support scanning.
    eth0 Interface doesn't support scanning.

    Any help would be appreciated...thanks.

    Re: wireless card not detected on acer laptop

    Thanks very much for your reply. I took a look at the links and even started on the instructions found at one of them, but I'm concerned that because I'm on an AMD 64 and have the x86_64 installation, these may not work for me.

    Here's everything I know about my laptop:
    Acer Aspire 4520
    AMD Athlon X2 Dual Core Processor 1K-53(1.7GHz, 2x 256KB L2 Cache)
    There's a sticker on the case that says I've got nvidia GeForce 7000M
