    Arrow Failed RTL-8188CUs installation

    There seem to be a fair number of posts regarding devices using the RealTek 8188CUs chip. I have an Edimax EW-7811Un which works great with Realtek's driver on 12.04 & 12.10. I installed it on a machine running the latest 13.04 daily. Realtek's driver does not install on 13.04 so far; I've included the script. The adapter behaved as it has on previous installs. It's recognized, the light comes on steady,should flash. it seems networks but after entering the passphrase, it is not recognized and returns to the 'enter passphrase' windows. I thought the 'dmesg' output might shed some light but I'm nowhere near knowledgeable enough to know what it means. I thought I'd copy/paste some output for your perusal and amusement. First off:

    Linux ubuntu1304-2ndfloor 3.8.0-9-generic #18-Ubuntu SMP Thu Feb 28 17:02:06 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

    Sorry the formatting is not better. I'm not sure how to fix it.

    Re: WiFi/Networking Gurus -- Some output from failed RTL-8188CUs installation

    First: Did you install all compilation tools necessary?
    Code:
    sudo apt-get install linux-headers-generic build-essential dkms
    2nd: Did you run the script as root?
    Code:
    sudo sh ./install.sh
    Whats the problem with the module r8712u, which is still loaded? Maybe the "new" Realtek driver does not work yet with kernel 3.8?!

    Alternatively, try this driver with dkms:

    But it was tested up to 12.10 only.

    How familiar are you with wireless networking troubleshooting? You might need this https://help.ubuntu.com/community/Wi...eShootingGuide If as you say, it sees networks (I am assuming "seems" is a misspelling - do it all the time myself) then that usually is an indication that the driver has been installed and is recognizing the wireless adapter. When we are brought back to the authentication window it is usually an indication that there is an issue with the passphrase or the encryption method set. Network Manager is usually good at setting the encryption method without user input. Try running the code suggested in that link
    Code:
    nm-tool
    What does it show you. Also
    Code:
    rfkill list

    Hi praseodym, thanks for checking in. I did run the script as root. I did not download linux-headers generic build-essential dkms, I can try that, I will also try your linked driver. r8712u works perfectly with the rtl-8192SU adapter in all versions I've tried. The only glitch with r8712u is that it requires a minor modification to resume properly after suspending. The script from RealTek works perfectly up through 12.10 but I've never gotten the 'baked-in' module to work with this adapter. I did report my experience to RealTek. It's possible they'll release an update to their installer once 13.04 is close to release. Getting 'baked-in' support would be good, this is a useful adapter for portable machines.

    Re: Failed RTL-8188CUs installation

    Was there ever any progress on this? I am using a RTL8192CU-based USB adapter on Xubuntu which seems to share a driver with the 8188. With 12.10 and the baked-in driver, it would detect but I got the same symptoms as the OP where it'd keep prompting for the wireless password even when I entered it in correctly. I blacklisted it and downloaded the v3.4.4_4749.20120806 driver from Realtek, compiled and installed it and it had been working fine from there. Then with every kernel update on 12.10 I'd have to recompile/reinstall but I just got used to that. Now I upgraded Xubuntu to 13.04 and it won't compile. I tried looking for a newer version but there was only a slightly-newer one, v3.4.4_4749.20121105, which exhibits the same compile error for me as the OP mentioned. From countless other posts on these forums, as well as other forums and even blog posts dedicated to the issue, the baked-in driver for the RTL8188/8192, while existing, has had known problems for a very long time. It'd certainly be nice if the baked-in driver had been fixed in 13.04 but that's clearly not the case so we're stuck trying to get the manually-compiled one to work... which used to, but not any more.

    Re: Failed RTL-8188CUs installation

    Yes, Tim Phillips has produced a great solution to this problem. See this thread:

    http://ubuntuforums.org/showthread.p...hlight=8188CUs

    Tim has made available a .deb file that fixes the 13.04 installation bug and included a dkms fix so it's no longer necessary to recompile after each kernel upgrade. Here's a link to the .deb file:

    https://code.google.com/p/realtek-81...9-ubuntu-1304/

    Do note that you need to blacklist the original drivers.
