    installing rtl8187L linux driver

    Realtek provides a linux driver for its rtl8187L chipset (note: not 8187b). I've downloaded it, but don't know how to install it. Since it's not a windows driver, i'm assuming ndiswrapper is not the way to go. I searched for documentation on how to do this, but came up empty. Surely this is documented somewhere? If anyone could provide me a link, I'd appreciate it. Please do not send a link to an rtl8187b install page...that has separate issues and requires the windows driver.

    Re: installing rtl8187L linux driver

    If you can see where it is now, Places -> Home, or, perhaps Places -> Home -> Desktop, then you can right click it and select 'Extract here.' Go to the directory that's then been created and see the README. Some prerequisites will be listed which can usually be satisfied with:
    Code:
    sudo apt-get install build-essential
    sudo apt-get install linux-headers-generic
    Post back if you get stuck.

    Re: installing rtl8187L linux driver

    Thanks for the reply. I think this is going to be complicated. When I use make to recompile the driver as instructed by README, it's unsuccessful. Reading the output, it looks as though there is some problem with one of the C scripts. If you're really dedicated and know programming like I don't, I could send you a copy of the output and the C file that appears to contain the problem (something about an invalid pointer).

    Re: installing rtl8187L linux driver

    It would help most to get a link to the package you downloaded. Then I will see if I can trouble-shoot the compilation.

    Re: installing rtl8187L linux driver

    You're a beautiful human being. The driver can be found here. Should you be successful, I will put up a how-to sticky and, of course, credit you.

    Just a few notes. Here's what I get from running make; the first reference to the softmac.c script that seems to be the beginning of the problem appears just a few lines below where all the directories/files are listed:

    Also, I have the latest version of of build-essential installed.

    UPDATE: Strangely, I was able to connect with no problems at a cafe last night. This in spite of the fact that lshw -C network lists no wireless driver. Is it possible that there is a hidden, native linux driver that is running my wireless and that I'm just getting a weak signal from other APs? Network Manager shows a strong signal from the APs that I'm dropping, but it also shows that I'm connected when I'm not so I don't know if I can believe it. I hope I'm not sending you on a wild goose chase.

    Re: installing rtl8187L linux driver

    I hope the native driver is working, because, despite working on this for hours and Googling for hours, I cannot get this to work. I have fixed some issues, others have popped up, run it on an earlier kernel, all to no avail.

    The native driver is rtl8187. You can see if it's loaded with:
    Code:
    lsmod | grep 8187
    If it is not loaded, try:
    Code:
    sudo modprobe rtl8187
    Then let's take a look at:
    Code:
    iwconfig
    ifconfig
    Thanks.

    Re: installing rtl8187L linux driver

    Yikes. Sorry I caused you that much trouble. I appreciate your efforts.

    Do I want to blacklist ehci_hcd, ohci_hcd in /etc/modprobe.d/blacklist or are these what are working for me?:

    So is the usbcore output from lsmod what tells me that the rtl8187 driver is loaded? The driver doesn't show up under iwconfig, but I do seem to be connecting from this cafe fine. Is there a way to configure my connection so I'm not dropping connections so often from other APs that seem to be stable for everyone else?

    Many thanks, again.

    Re: installing rtl8187L linux driver

    Do I want to blacklist ehci_hcd, ohci_hcd in /etc/modprobe.d/blacklist or are these what are working for me?
    No, they seem to br working perfectly.
    that the rtl8187 driver is loaded?
    Yes, it is loading fine.
    The driver doesn't show up under iwconfig
    It wouldn't. It would show under:
    Code:
    sudo lshw -C network
    I can't see anything about your settings that I might change. Try to keep the USB device as high as you can. Some of your buddies no doubt have laptops that have the antenna surrounding the screen. In borderline conditions, having your antenna a bit higher may make all the difference.

    Let's both keep looking for a better RTL8187 driver. The very few out there today are problematic.

    You might try ndiswrapper, if you are a bit intrepid. It's not hard to install and even easier to remove, if it doesn't meet your expectations.

    yes, let's both keep looking. I also forgot to mention that the driver doesn't show up under lshw -C network either, as far as I can tell:

    [SOLVED]: installing rtl8187L linux driver

    The key to making this device work, it turns out, is not to install ANY driver. The native driver in Hardy works just fine. Following the various posts for installing the 8187b driver will only lead you down the same frustrating road I walked down. Likewise, the driver offered for linux by the realtek website does not work.
