Comment 5 for bug 749871

I can confirm what Chad Billman said in post #4. The Realtek 8192CE driver which is currently included in the Natty kernel is very unstable. I also experience situations where no traffic is sent or received for a period of a few seconds up to a few minutes. This happens 2 to 3 times a day. Sometimes the connection also drops completely, forcing me to reconnect. Installing the official Realtek driver improves stability a bit. Ironically, compiling the version for >= 2.6.35 kernels (version 0003.0401.2011) breaks the system, but the version for <= 2.6.34 kernels (2.6.0006.0321.2011) works fine. I still experience random connection freezes and dropouts, however, albeit on a less frequent basis.
