Wireless connection frequently drops [deauthenticating by local choice (reason=3)]

[Guillaume Romagny]

Hello,

I have frequent (at least every 5 to 10 minutes) wireless stop/restart with WPA
on my (extract from Lenovo website, laptop built on July 2011)
ThinkPad Edge 15 (0319-A13)
P6100(2GHz), 2GB RAM, 500GB 5400rpm HD, 15.6in 1366x768 LCD, Intel HD Graphics, CDRW/DVDRW, 802.11bgn wireless, Bluetooth, 1Gb Ethernet, UltraNav, Camera, 6c Li-Ion, No preload

I have installed first Ubuntu beta from 11.10 and now beta testing beta 12.04... no improvement

I have tested different wireless routers, short distance/long distance from the router, but still the same problem as in #548992 (which considered as FIXED)

the wifi chipset is
03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01)

cat /proc/version_signature
Ubuntu 3.2.0-23.36-generic 3.2.14

I have the lastest BIOS update from Lenovo
