    HOWTO: Get RTL8187B (ID: 8197) Working. Step by Step

    There is now native support for this wireless card in the kernel 2.6.27 which is in Ubuntu 8.10

    This driver is somewhat buggy. When running at 54MB/s it works fine for about 2-5 minutes and then connections start to time out.

    To temporally fix this, put this command in your /etc/rc.local file.

    Code:
    gksu gedit /etc/rc.local
    and put this BEFORE the exit 0,
    Code:
    iwconfig wlan0 rate 5.5M fixed
    This will run at startup.
    Having a bit rate of 5.5M will temporally fix the timeouts and quality. The errors may still occur but not as much.

    ___________________________________

    Ubuntu 8.04 & Ubuntu 7.10

    There are 2 ways of getting it to work. The native way or Ndiswrapper way.

    Native:
    Look here. It explains everything

    http://linuxwireless.org/en/users/Download

    (You want to download the Compact Wireless Old)


    Ndiswrapper:

    This is mainly for the ID of 8197 but can be used for all the RTL8187B. Checking 'lsusb' will give you the ID number of your wireless card.

    1. Install Ndiswrapper
    With no Internet:
    First put in your Ubuntu CD when logged in.
    Then go, System > Admin > Software Soruces > Tick the cd box at the bottom.
    In Synpatic Package Manager (System > Admin >) and locate reload button. Press that, wait a bit. Will give errors saying cannot download etc, Don't worry about that. Then follow the With Internet' bit because your using your CD as 'The Internet'

    With Internet:
    Go to Add/Remove and search for Windows Wireless Drivers
    Install it.
    Thats Ndiswrapper Installed.


    2. Install the Driver
    Go to System > Administration > Windows Wireless Drivers > Install New Driver > Locate the driver > Install.
    It should say:

    Hardware Present: Yes

    Now, in Network Manager, you should see wireless access points.

    *If you cannot connect with WEP, remove Network Manager and Install Wifi-Radar

    Hope this worked for you...and if you have any problems, please post in here.

    Also, for a alternative way, check here: https://help.ubuntu.com/community/Wi...ealtekRTL8187b

    Thanks,

    Heh...
    I modified the win98 driver as you instructed but when i try to install it it still says hardware is not present.

    Also, I checked out my /etc/rc.local file and all its says is:

    #!/bin/sh -e
    #
    # rc.local
    #
    # This script is executed at the end of each multiuser runlevel.
    # Make sure that the script will "exit 0" on success or any other
    # value on error.
    #
    # In order to enable or disable this script just change the execution
    # bits.
    #
    # By default this script does nothing.

    exit 0

    What am I doing wrong?

    Sorry for a late reply, I went bed.

    You have the same card as me.

    First thing you need to do is get the driver to recognize the wireless card.

    Use this attached file (its the driver) and extract and use that.. see if that worked. :\

    Re: HOWTO: Get RTL8187B (ID: 8197) Working. Step by Step

    No luck...

    It doesn't make any sense. Do you think there could be a problem with my version of ndiswrapper or that the modified version of the RTL8187b driver I installed from this website http://www.datanorth.net/~cuervo/rtl8187b/ is causing problems?

    Re: HOWTO: Get RTL8187B (ID: 8197) Working. Step by Step

    Yes... that might be it. As the modified driver is very buggy it might mess things up.

    Uninstall it. I do not know how to do that so you might need to ask on the forums.

    After that, uninstall ndiswrapper, insatll it again and try again.

    As you have the same wireless card as me. It should be the same. It should work.

    I reinstalled hardy as well as ndiswrapper and still no luck. My rc.local file still looks the same too.

    Re: HOWTO: Get RTL8187B (ID: 8197) Working. Step by Step

    You shoudln't touch the rc.local file yet. That is needed when you have the wireless card working.

    I do not knon why it doing this :\
    It works on mine and I have the same card as you.

    I really don't know why

    Email Realtek and ask for a driver for that ID. I got one but didn't work for me. (it is a windows driver made for ndiswrapper and for the ID of 8197)

    I would attach it but I do not have it anymore
