    Default Any hope for Realtek 8811CU wireless LAN 802.11ac USB NIC working

    I see several threads mentioning other Realtek USB dongles but not the >Realtek 8811CU wireless LAN 802.11ac USB NIC

    Any hope at all of it being able to be setup in Leap15 and Leap 15.1 when It is released?

    I can now print with openSuSe Leap! YAY!!!
    I can backup my iPod and iPad with Windows, can't with Linux.(Will get there someday!)

    Hi
    AFAIK, user Sauerland's 8812AU driver should work with that device...

    Can you post the 8811cu output from the command;

    Code:
    usb-devices
    Need the usb id's to confirm the driver is compatible.

    Hi
    Looks like one user got it to work...
    https://github.com/MingxuZhang/rtl8821cu

    Probably easier to go find one that has OTB support.....

    I think you are right. I have been looking for a different one that has OTB support.
    I don't think she will be happy with one that has an antenna on it as she moves the PC quite a bit during the day.

    So far my wife's laptop is doing her well with just onboard 2.4G. I will ask her if she want is 'faster' or if she is satisfied with it as it is.

    Thanks for the link. I believe I did run across that one in my search travels and put link to it somewhere.
    So thanks to you I have it again IF I want to tackle another problem child.

    PS, Global Mods Attention!!
    Someone really needs to fix that 'reputation' thing so that we can add to a members reputation more than once or twice! Just saying.....

    I downloaded that zip file in malcolmlewis's post above, unzipped it and turned the results into a .tar.gz file.
    I have made an attempt to do .rpm from it, but am kind of leary of pulling the trigger to complete the rpm.

    I would rather pour acid in my eyes than look at yet another long and confusing 'how to make an rpm' web site, or watch another 30 minute boring video.

    NOT that they haven't been instructive, they have, but...... the boring factor is putting me to sleep! End of whine!
