In this notebook clevo W150HRM (with a reatek card: rtl8192ce       :
Realtek Semiconductor Co., Ltd.|RTL8188CE 802.11b/g/n WiFi Adapter
[NETWORK_OTHER] (vendor:10ec device:8176 subv:10ec subd:9196) (rev:
01) ),  runing kernel-3.3.4 with compat-wireless currently
NetworkManager is not detecting any wifi network.

And in notebook clevo M761SU (with a Realtek card 8187B), running
Windows 7 Ultimate, it detects 6 wifi networks.

Now if i run in clevo W150HRM the kernel-3.3.1 it will detect the same
6 wifi networks that are detected in clevo M761SU running Windows 7.

Is the fix http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=commit;h=eb641120479de7ee703fabb5e6ee0ec7947474ba
an improvement? Or would it need some more tweaks, since i have turned
the notebook clevo W150HRM it started by detecting 6 wifi networks,
than passed to 3, then passed to 1, and now is detecting none.

I know i have been insisting on this but its because i cant see here
an improvement with last fix (just not to mention the problem with
keyboard and mouse where i had to turn off power management), i just
hope that my interventions can be seen as a try to improve things and
not as criticizing anyone work.
