Bug Description
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 wireless- 3.5.1-1- snpc driver- select rtlwifi
cd compat-
./scripts/
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.
