First of all, not everyone has trouble with rtl8192ce. Neither I nor the Realtek
group can reproduce the troubles that you describe. Because of that we are not
able to figure out what people are seeing.
The driver in the standard kernel used in Ubuntu 11.04 has been revised. If
possible, you should obtain the compat-wireless package built for Ubuntu. If it
does not exist, then get the compat-wireless source and build the package. That
will get you the latest set of fixes.
One thing you might try is loading the module with the parameter "ips=0".
