SEams that was your last fix for rtl8192

  that reduced the wifi force, thus detecting less wifi networks.

Running without that "fix" the notebook detects more wifi networks,
seams like the antenna have more force.

You keep talking about "antenna force". What does that mean?

That patch keeps your device from running forever at a maximum of 1 Mbps
by
adjusting the initial gain of the RX amplifier. You may reverse it if you
want so that you can detect more APs when you scan; however, most people
prefer to get better performance from the device. That patch will not be
reversed.

Could you please clarify a litle more about the why and the patch fix?

Before that patch, when the device scanned after the connection was up and
running, it set the gain very low. When that happened, the receiver failed
to see any info coming from the AP. The AP would retry several times, and
then cut its transmit rate to 1 Mbps. That rate would stay until rtl8192xe
was unloaded and reloaded. To me, that is a lot bigger problem that what you
are seeing, which is why I will not change it back!

Ok i have been using only kernel-3.3.4 (with compat wireless) and i
have been seeing a strange behaviour, it starts by detecting for
example 6 wifi networks and passed some time the 6 wifi become 1, and
passed a litle longer NetworkManager reaches the point of not showing
any Wifi network.
Then i restart wpa_supplicant and i get back 3 wifi networks.

With kernel-3.3.1 i dont remember this ever happened...

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.
