Bug Description
I have a realtek rtl8192_pci wireless card, which is regularly disconecting from the access point after upgrading from 10.10 to 11.04.
While under continuous traffic, the disconnects do not happen (ping is sufficient to remain connected), however normal web browsing is not sufficient, and about once per minute the card will disconnect and re-associate.

During a constant ping, dmesg has the following errors but the connection is stable (two instances shown which occur 100 seconds apart):

Some of the disconnections are enough to trigger an error in the system tray, however this does not show for every entry in dmesg.
I will continue to test and try to narrow down this bug
I'm having the same issue with the rtl8188ce (using the rtl8192ce driver). However, my dmesg looks different. Regardless, I'm simply subscribing to the bug.
I'm curious if natty contains the latest driver from RealTek. There was a new release on April 6th, which supposedly solves dropped connections.

When I tried to make/make install, I got a kernel panic on boot, and had to revert.
