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!

That in fact used to happen severall times, if the wifi network was
not near enough it would be hard to connect to it, and if this patch
fixes its good knews in a way, but its not very good to loose the
ability to check wifi networks, but if you didnt find a better
intermediate point between loosing the wifi force and have better
connection its not me whos going to say otherwise, your the expert
here :)

But what happens now is that in NetworkManager i can see 3 wifi
networks, but if i run kismet or airodump-ng, it
can detect wifi networks that do not appear listed in NM.
