    Sitecom Wireless USB (WLA-2100) with Ralink chipset

    First posts below are about a Realtek chipset, but the device seemed to have a Ralink chipset. (Sorry for the confusion).
    The problem was about the 0df6:0078 product. See this post for the solution.

    ================================================== ==

    I've bought a Sitecom wireless USB (WLA-2100) with a Realtek RTL8192SU chipset and can't get it to work on my machine. I've read several posts about it and tried several options but was unsuccesfull. I'm new to Linux but I've learned a lot with this issue!

    Some info:

    Your thread is where it should be (unless it was moved silently from somewhere else to here - Networking & Wireless section). And if you ever want to request or report something to the admins/mods, you can always use the "Report Post" button that appears below every post.

    Regarding the wireless problem, please follow the instructions in this post to download and run 'wireless_script' (experimental version) and post back the report it generates : http://ubuntuforums.org/showpost.php?p=13024222

    Re: Sitecom Wireless USB (WLA-2100) with Realtek RTL8192SU chipset

    The Realtek drivers site shows Linux support for RTL8192SU: Linux Kernel 2.6.18~2.6.38 and Kernel 3.0.2
    I'm on Kernel 3.13...

    How can I get it to work?

    Coffeecat, sorry if I write here after you splitted the thread. I noticed something on the dmesg message frogglewoggle posted:
    [ 1126.160340] usb 2-2.4: Manufacturer: Ralink
    I think that it's the same adapter that I have, and it's a Ralink 2800 one, not a Realtek.

    Tells us that your 0df6:0078 usb device is a Ralink, not Realtek. Is there a reason why you are trying to enable a driver for a Realtek RTL8192SU chipset and have put "Realtek RTL8192SU" in your thread title?

    EDIT:

    @menth1979, I didn't see your post when I posted.

    Yes, you are right - the OP appears to have a Ralink but for some reason is investigating the Realtek driver.

    I think because the OP is confused by the description page they linked to : http://www.wireless-driver.com/nl/si...tility-ver201/

    It clearly says -
    Chipset: Realtek RTL8192SU
    But then, below the (Mac OS) driver download link, it also says -
    Ondersteunde hardware-id's:
    Code:
    USB VID_0DF6&PID_006C
    ("Ondersteunde" in dutch is translated to "Supported" in English)

    So it seems that either the OP got an entirely different device, or probably Sitecom changed the chip inside. It is not uncommon for the vendors to change the chips in different versions of a device.

    In any case, the device "0df6 : 0078" appears to be using Ralink chip inside, as the dmesg identified.

    As for the solution, I frankly have no idea. This device doesn't seem to be supported natively and I don't know if a driver for Linux exists anywhere outside.

    For this very same reason, I am hesitating to post in the other thread, because others may have a solution while I don't have any.

    PS:
    From the 'echoing' of device id trick (evident in their /etc/modprobe.d/r8712u.conf file included in the wireless_script report), it seems the OP probably followed some post by praseodym, since he is the only one whom I have noticed trying that kind of trick with PCI devices. Some of us don't think it works with PCI devices, but we keep learning new things and are always open to corrections.

    Thanks for your sharp observations. I indeed was mislead by the information on the page I linked to and I missed to dmesg line about the Ralink. I would change the subject of the post if I could but don't know how. So it seems my WLA-2100 device has a Ralink chipset .

    Re: Sitecom Wireless USB (WLA-2100) with Ralink chipset

    I've edited the thread title for you to remove the reference to Realtek. According to discussion on another thread with what seems to be the same device, that Ralink chipset is problematic. Hopefully, someone will be able to help you.
