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. More
