    Angry Wireless confusion

    OK I have installed and un-installed 3 different versions of Ubuntu. My forth is a re-install of v9.10. During all these installs I have had difficulty getting my wifi to work.

    During my last install I left the ISO in the drive by mistake so when the system rebooted it loaded from the disc in demo.... This was interesting because in the demo the program manager showed 2 drives for wireless, 1 Broadcom STA and 2 Broadcom b43xx. I tried loading the STA AND IT WORKED! (sorry it could have been the b43xx, for the time being it's insignificant) Upon my excitement I restarted the computer and removed the disk went to my Ubuntu set up and ...what the Broadcom choices weren't there Why?

    Now I am running Win 7 Home 32bit on my main drive and have Ubuntu loaded on its own drive. I have a Netgear WN311b wireless N card installed. Again my confusion is why it worked in demo (off the cd) but doesn't from full install.

    I read on the web to try inserting my supplied disc from Netgear and then search program manager. It now showed the two for-mentioned Broadcom programs, but this time wouldn't install them. On the b43 I got an error message and on the STA it searched extracting and loading this continued for a 1/2 hour with no progression. I couldn't close the PM or the extracting and loading box, so I had to restart the computer.

    I still don't have wireless and after three weeks of trying I'm about ready to throw in the towel

    Any assistance would be appreciated,

    Tom

    Re: Wireless confusion

    Instead of reinstalling again try fixing it.
    Connect to a wired connection so you can get drivers and updates.
    Open a terminal
    Applications > Accessories > Terminal
    and run
    Code:
    sudo apt-get update
    Then go to
    System > Administration > Hardware Drivers
    and see if there's a driver available

    Since you mentioned Broadcom STA and Broadcom b43xx you may find your solution here:
    The Definitive 9.10 Broadcom Solution Guide

    If all that fails then
    Open a terminal
    Applications > Accessories > Terminal
    and run

    If internal PCI
    Code:
    lspci
    That's LSPCI in lower case, and post the results.

    If it's a USB adapter
    Code:
    lsusb
    That's LSUSB in lower case, and post the results.

    Re: Wireless confusion

    Your steps are appreciated, however, my dilemma is a wired connection. 1 I'm handicapped, 2 my system is on ground floor and all inter-net connections are on third floor. I haven't the ability to move computer to this level. Do I have the ability to download drivers to accomplish what you've suggested?

    I am still confused as to why I was able to get the Demo to hook to the net but can't do the same w/ full version. Can the drivers that make the Demo work, be transferred from Demo to full, on the ISO disc?

    Thank you, Tom

    The link provided previously tells you how to install those drivers without wired access directly from the Live CD.

    Here is the link again

    Re: Wireless confusion

    Unfortunately no luck. The steps given, I had already tried, I know, I know your response to this... I re installed Ubuntu. I did this because the previous time I tried this step, I had tried installing both b43 and STA both not working and wouldn't let me uninstall. So I re loaded 9.10. I tried the steps again, this time when it came time to search the cd it asked me to install cd in cd drive.... It was already there and showing on on the desktop. I let it search for 20 min or so and nothing happened. When I canceled out, of course I got the error of non installation.

    So here is the info requested

    Re: Wireless confusion

    Well it looks like I have a tough road ahead of me. I'm still curious as to why the demo found and offered the correct drivers to make the inter net work! It makes no sense that the demo works but the full does not! Any thoughts as to why this happens?

    From what I understand ( and I am often wrong!) the driver is made available, but is actually proprietary and can't be directly included. ( I'm sure i will be corrected soon! ) Anyway, further searching seems to indicate that the correct driver was the STA version. It is available here

    http://www.broadcom.com/support/802.11/linux_sta.php

    read the readme first. It is well explained, but may be more that you want to try.
    Anyway, how about going to the terminal Applications>>Accessories>>Terminal and copy/paste the outputs of the following back here.

    Code:
    sudo lshw -C network
    sudo iwlist scan
    iwconfig
    lsmod
    Those a lowercase L not 1's. Please post these with the use of the code tags (#) for readability.


    Forgot you don't have ethernet, however you are communicating you can simply use a usb key and do something like this

    You can convert your terminal output to a text document easily:

    sudo lshw -C network > lshw.txt

    Then you will find a text document in your /home/user directory, in this case lshw.txt, which you can drag-n-drop onto a flash drive and see it in Windows with, IIRC, wordpad repeat with different names for each of those above.
