Did this issue start happening after an update/upgrade? Was there a kernel version where you were not having this particular problem? This will help determine if the problem you are seeing is the result of the introduction of a regression, and when this regression was introduced. If this is a regression, we can perform a kernel bisect to identify the commit that introduced the problem.

The built in rtl8192cu driver has never worked for me. I only got the
device 4-5 months ago and at first I couldn't even connect I believe
that issue was related to LP#852190
(https://bugs.launchpad.net/ubuntu/+source/linux/+bug/852190/comments/170).
I switched to the native driver with some patches i found online setup
via dkms. That has worked well, but I figured I should report the
issue with the rtl8192cu driver.

I did test the mainline kernel last night (9/2) and the issue was still present.

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report[0]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

Please follow the instructions on the wiki page[0]. The first step is to email the appropriate mailing list. If no response is received, then a bug may be opened on bugzilla.kernel.org.

Once this bug is reported upstream, please add the tag: 'kernel-bug-reported-upstream'.

I have emailed the mailing list. I did find two other people having a similar issue [0] and [1]. Hopefully there will be a resolution soon. The latest mainline kernel breaks the proprietary driver, which I have been using as a fallback.

I received a response from upstream [0]. He believed the issue is "a bad interaction with the Ubuntu front-end to wireless." Doesn't Ubuntu just use Network-Manager? Are there any Ubuntu specific modifications?

A patch was provided, but it is not expected to correct the issue. I am going to attempt to get the latest source, apply the patch, and compile the module myself.

Hello,

I'm greatly impacted by this as well. I'm going to try to provide some more details, which is a pain as my connection goes down every few minutes because of this problem...

1) here is a "successful disconnect cycle": It should not disconnect in the first place, but at least is reconnects... (I'm not in Germany, so not certain why it tries to set "cfg80211: Calling CRDA for country: DE" )

master_patch_09_24.txt Edit (37.9 KiB, text/plain)

Upstream has provided me a patch. It it only for the 3.11 kernel as there have been significant changes between 3.8 and 3.11 to the rtlwifi drivers. I wasn't given a timeline as to when the patch would be committed. There was also provided updated firmware.

For those that like me that have never patch a kernel module here are the steps I took:

As root:
    apt-get install linux-source
    cd /usr/src
    tar -xf linux-source-3.11.0.tar.bz2
    cd linux-source-3.11.0
    patch -p1 < /path-to/master_patch_09_24.txt
    cp /lib/modules/`uname -r`/build/Module.symvers .
    make clean
    make oldconfig
    make prepare
    make modules_prepare
    make SUBDIRS=scripts/mod
    make SUBDIRS=drivers/net/wireless/rtlwifi
    for i in `find . -name '*.ko'`; do cp $i /lib/modules/`uname -r`/kernel/$i;done;
    #make sure to unblacklist the modules if you have blacklisted them and to blacklist the vendor 8192cu if installed
    reboot

To rollback:
apt-get --reinstall install linux-image-`uname -r`

Meanwhile, maybe you will find this useful. It's the Realtek 8192cu driver ported for Ubuntu 13.10: https://github.com/pvaret/rtl8192cu-fixes

+tgrundle does that patch from #9 work for you? It's not working for me. I built per your instructions-- thanks for spelling it out like that. Now I see in dmesg that it is loading the new firmware, but then it repeatedly gets either "authenticating with ... timed out" or, when it does manage to authenticate, "associating with ... timed out" instead.

Yes, I have been using the patched rtl8192cu driver for a month without any issues.

The guys on the linux-wireless team were really good to work with. I suggest opening your own bug on launchpad and then follow the directions in comment #5.
