I've been testing this device:
02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188CE
802.11b/g/n WiFi Adapter (rev 01)
Subsystem: Realtek Semiconductor Co., Ltd. Device 8175
The drivers provided with Precise are very unreliable. Same fault as
above, either it won't connect to the network at all, or it connects and
works for a short while and then fails (drops the network and can't
rejoin). I could reliably reproduce this by flood-pinging the default
gateway over wireless, which caused the card to crash within 5 minutes.
I also had stability problems with the 0006.0514.2012 drivers. However
Realtek has just released a new driver version, 0007.0809.2012, which I
have found to be rock solid. Tested flood pinging for several hours with
no disconnect. I think they've finally fixed the issues with this
device.
I built a DKMS package and tested it on Precise and it works well. You
can build and install the package like this:
git clone git://github.com/aptivate/linux-ischool-classmate.git
cd rtl8192ce-dkms/r8192ce-0007.0809.2012-1~classmate~121102~1cw
debuild -i -us -uc -b
dpkg -i ../r8192ce_0007.0809.2012-1~classmate~121102~1cw_all.deb
