    Wireless issue


    I have Wicd installed and when i hover onto the wireless it says it cant find any wireless signals. my Wifi is wpa protected so i installed wpa_supplicant also.

    Code:
    $ifconfig wlan0
    wlan0  -link ecap:Ethernet hwaddr: mac #
    broadcast multicast mtu:1500 metric:1
    rx packets:0 errors:0 dropped:0 overruns:0 frame:0
    and so on

    so it recognizes it but it cant find any wireless networks.

    Code:
    $iwconfig
    lo no wireless extention
    eth0 no wireless extention
    wlan0 ieee 802.11bg mode:managed access point: not-associated
    tx-power=0 dbm
    retry long limit:7 RTS thr:off fragment thr:off
    power management:off

    First thing, check under "Preferences" in wicd and make sure the interface name is set to wlan0.

    Does this return local networks? (As root)
    Code:
    iwlist wlan0 scan

    #iwlist wlan0 scam
    wlan0      Interface doesn't support scanning : Network is down

    Ah, you haven't installed the right driver. Well, sort of. There are two drivers for broadcom cards, which work for various chipsets with some overlap.

    The b43 is what you're loading currently, and it needs extra non-free firmware available from the AUR here. In theory, this driver should work with your wireless card as of kernel 2.6.32, I believe. And in fact I have a netbook with the same card and it has worked - but only intermittently.

    The other driver is released by Broadcom, which also includes non-free components, and it is available from the AUR here. This is the driver I use. The main thing to be aware of with this driver, is that after kernel upgrades, it needs to be rebuilt against the current running kernel. I keep the source package and PKGBUILD handy on my computer so if I upgrade the kernel, I can rebuild the package without needing internet access.

    I noted another package for this driver with an patch included for kernel 2.6.33. The regular AUR package works for me, but if you have trouble, you could try that one as well.

    More info on Broadcom cards in the Arch Wiki.
