I have Realtek PCI adapter that lspci reports as "Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01)".
It uses the rtl8192ce driver. With the default driver and firmware supplied by Ubuntu 13.04 (linux-image-3.8.0-23-generic, 3.8.0-23.34; firmware rtl8192cfw.bin, sha1 4fc1e72c5f82cf95c62050c56cce074d90c3e579) the connection was very unstable, exactly as described in the above comments. That is, reason=6 and reason=15 disconnects, and the link going dead after some time from connection.
I obtained Realtek's vendor rtl8192ce driver version 0012.0207.2013 from their download site and built it.
First, I forgot to upgrade the firmware, only loading the newly built rtl8192ce.ko. This did not improve the situation, and similar problems as with the Ubuntu-supplied driver persisted.
Then, I upgraded also the firmware (to rtl8192cfw.bin, sha1 bbd9b4e2c53e18df3aed03d22eee8d8c22ef9a8e). The connection seems now quite stable, the dropouts seem to be gone now.
Here's one more data point:
