Realtek RTL8188CE wireless does not work in Ubuntu 12.04LTS

[Carlos Blanquer Bogacz]

I have a computer using a wifi device Realtek RTL8188CE, which is constantly dropping connection and not being able to reconnect.

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu
Ubuntu 12.04LTS freshinstall from 2012-11-04

2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center

I only know the modules that generate problems:
- rtl8192ce
- rtl8192c_common

3) What you expected to happen
WiFi to work stable.

4) What happened instead
WiFi too unstable to be used: connects (WPA) but after some seconds drops, tries to reconnect and cannot again until reboot.

(* as of research, there are issues with realtek since version 11.10 *)
(* I just found a question but no bug regarding that device - the question from July is not answered and automatically closed *)

I finally fixed this problem by compiling and installing the latest drivers from Linux Wireless in Ubuntu 12.04, in my case the "compat-wireless-3.5.1-1-snpc.tar.bz2" package: http://wireless.kernel.org/en/users/Download/stable/

One needs the header files for his kernel and the build-essentials package. I recommend also to run the script "driver-select" with the option rtlwifi before compiling because one doesn't need the other drivers and it reduces building time:

sudo apt-get install linux-headers-$(uname -r) build-essential

tar jvxf compat-wireless-3.5.1-1-snpc.tar.bz2
cd compat-wireless-3.5.1-1-snpc
./scripts/driver-select rtlwifi
make
sudo make install

But the downside is you have to rebuild the driver after every kernel update.

I'm running the driver for two days now with excessive closing and opening the lid and didn't get any disconnects.

Carlos Blanquer Bogacz, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc5

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

Not an issue anymore. It seems that some kernel update fixed it several
months ago. I forgot to report to the bug record.
Bye.
