Hello, I have a similar problem. Too much of a noob to be sure it's the same so if someone can give me feedback on anything I can do to get this bug in a complete, assigned status, I'd really appreciate it. Meanwhile here's some info: After initial install I tried troubleshooting according to posts I found on forums and I have this info from phase 1. jvnn@jvnn-desktop:~$ lspci 02:09.0 Network controller: Texas Instruments ACX 100 22Mbps Wireless Interface jvnn@jvnn-desktop:~$ iwconfig lo no wireless extensions. eth0 no wireless extensions. jvnn@jvnn-desktop:~$ lsmod | grep 'acx' (nothing) jvnn@jvnn-desktop:~$ dmesg | grep 'acx' (nothing) jvnn@jvnn-desktop:~$ dmesg | grep 'module' [ 0.918991] brd: module loaded [ 0.919708] loop: module loaded jvnn@jvnn-desktop:~$ dmesg | grep 'wlan' (nothing) jvnn@jvnn-desktop:~$ sudo lshw -c network [sudo] password for jvnn: *-network:0 description: Ethernet interface product: 82562EZ 10/100 Ethernet Controller vendor: Intel Corporation physical id: 8 bus info: pci@0000:02:08.0 logical name: eth0 version: 02 serial: 00:11:09:8e:72:e5 size: 10MB/s capacity: 100MB/s width: 32 bits clock: 33MHz capabilities: pm bus_master cap_list ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=e100 driverversion=3.5.24-k2-NAPI duplex=half firmware=N/A latency=32 link=no maxlatency=56 mingnt=8 multicast=yes port=MII speed=10MB/s resources: irq:20 memory:f6011000-f6011fff ioport:a000(size=64) *-network:1 UNCLAIMED description: Network controller product: ACX 100 22Mbps Wireless Interface vendor: Texas Instruments physical id: 9 bus info: pci@0000:02:09.0 version: 00 width: 32 bits clock: 33MHz capabilities: pm bus_master cap_list configuration: latency=32 resources: ioport:a400(size=32) memory:f6010000-f6010fff memory:f6000000-f600ffff jvnn@jvnn-desktop:~$ iwlist scan lo Interface doesn't support scanning. eth0 Interface doesn't support scanning. jvnn@jvnn-desktop:~$ lsb_release -d Description: Ubuntu 9.10 jvnn@jvnn-desktop:~$ uname -mr 2.6.31-14-generic i686 --------------------------- --------------------------- Then, phase 2, I started following instructions in the patch topic http://www.uluga.ubuntuforums.org/showthread.php?p=8283559#post8283559 Here's some data from phase 2: jvnn@jvnn-desktop:~$ mkdir acx jvnn@jvnn-desktop:~$ cd acx jvnn@jvnn-desktop:~/acx$ wget http://downloads.sourceforge.net/acx...080210.tar.bz2 jvnn@jvnn-desktop:~/acx$ tar xjvf acx-20080210.tar.bz2 jvnn@jvnn-desktop:~/acx$ wget http://cc.oulu.fi/~rantalai/acx_karmic.patch jvnn@jvnn-desktop:~/acx$ sudo apt-get install patch jvnn@jvnn-desktop:~/acx$ patch -p0 < acx_karmic.patch jvnn@jvnn-desktop:~/acx$ cd acx-20080210/ jvnn@jvnn-desktop:~/acx/acx-20080210$ make -C /lib/modules/`uname -r`/build M=`pwd` make: Entering directory `/usr/src/linux-headers-2.6.31-16-generic' LD /home/jvnn/acx/acx-20080210/built-in.o CC [M] /home/jvnn/acx/acx-20080210/wlan.o CC [M] /home/jvnn/acx/acx-20080210/conv.o CC [M] /home/jvnn/acx/acx-20080210/ioctl.o CC [M] /home/jvnn/acx/acx-20080210/common.o CC [M] /home/jvnn/acx/acx-20080210/pci.o CC [M] /home/jvnn/acx/acx-20080210/usb.o LD [M] /home/jvnn/acx/acx-20080210/acx.o Building modules, stage 2.
