    Apple powerbook G4 wireless problems

    1 ) Machine Brand and Model (PC/Laptop):
    Apple Powerbook G4 Titanium


    2 ) Wireless Brand, Model and Wireless Chipset:
    Code:
    $ lspci $ lsusb
    here is output from lspci: doesn't seem to show wireless

    0000:00:0b.0 Host bridge: Apple Computer Inc. UniNorth 1.5 AGP

    (hint) use grep to get only information about the Wireless
    Code:
    $ lspci -nn | grep 'Wireless Brand'
    I am struggling to get any output from the above code. maybe because i don't know what to put for 'wireless brand'

    3 ) check interface:

    Code:
    $ ifconfig $ iwconfig
    ifconfig:

    eth0 Link encap:Ethernet HWaddr 00:03:93:b3:bc:aa
    inet addr:192.168.1.141 Bcast:192.168.1.255 Mask:255.255.255.0

    (hint) if the Wireless interface name is wlan0 you can also use
    Code:
    $ iwconfig wlan0
    wireless driver is named eth1 for some reason but here is output for iwconfig eth1

    Re: Apple powerbook G4 wireless problems

    Your post was two weeks ago, with no responses, so I don't know if you've given up in despair.
    I'm struggling with the same problem, and therefore cannot claim any expertise--just a lot of empathy!

    I've managed to get a partial solution with basically the same hardware, and I'm running 10.10 instead of 10.04. I can connect to a WEP-encrypted access point but not to a WPA one, so I'm still working on this.

    First, it must mean something that you don't get a wireless entry with lspci. You get:
    .
    .
    0001:10:0b.0 Host bridge: Apple Computer Inc. UniNorth 1.5 PCI
    0001:10:17.0 Unassigned class [ff00]: Apple Computer Inc. KeyLargo Mac I/O (rev 03)
    .
    .

    I get:
    .
    .
    0001:10:0b.0 Host bridge: Apple Computer Inc. UniNorth 2 PCI
    0001:10:12.0 Network controller: Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller (rev 03)
    0001:10:17.0 Unassigned class [ff00]: Apple Computer Inc. KeyLargo/Intrepid Mac I/O
    .
    .
    in the same spot.

    It must mean something, although what I cannot say.

    The other thing I see in your output is that you appear to have the wrong driver for the card. You'll need to get the b43 driver for it.

    I see on other posts that this Broadcom controller that is the 'Airport Extreme' in the Macs is problematic everywhere. In order to make it work you need to update the firmware, and Broadcom does not make that easy. You need to download and install an 'fw_cutter' app to cut the firmware out from a Broadcom firmware file.

    Here's a link with a full discussion of the Broadcom driver/firmware issue, with documentation and instructions: http://wireless.kernel.org/en/users/...acy_and_b43.3F

    And, I've seen other posts suggesting that the node will need to be wlan0 rather than eth1. I've lost the links where I saw that discussion. But, maybe installing the driver will get that done.

    However, there is still the problem I have--if I only had a WPA access point I would still not have a connection, but because I have both a WPA and a WEP going, I can confirm that I can connect with the latter but not the former. I saw one reference in passing that old Broadcom cards (which I have--see above--and that you probably do as well although I have no idea why lspci doesn't show it to you) cannot support WPA. Still chasing that one.

    Sigh.

    Good luck.
