12.04 wifi on pavilion g6 don't work

[mondom]

sorry for my continuous posts, but it seems in my pavilion g6 the wifi don't work yet!
i've installed this

sudo apt-get install --reinstall linux-headers-$(uname -r) build-essential dkms patch fakeroot unzip wget http://media.cdn.ubuntu-de.org/forum....5.0.3_DPO.zip unzip angepasster-2011_0406_RT5390_RT5392_Linux_STA_V2.5.0.3_DPO.zip cd angepasster-2011_0406_RT5390_RT5392_Linux_STA_V2.5.0.3_DPO/ sudo make sudo make install sudo modprobe -v rt5390sta sudo depmod -a sudo update-initramfs -u

and to activate this driver

echo "options rt2800pci nohwcrypt=1" | sudo tee /etc/modprobe.d/rt2800pci.conf sudo modprobe -rfv rt2800pci sudo modprobe -v rt2800pci

the connection works, but the range of the connection was only few meters
so I do this command

sudo iwconfig wlan0 power off

now the connection rarely work from another room, but disconnected often and to reconnect it take much time (when it reconnect!)

there is a stable solution for my pc, I begin to despair
thank

I've found this

it seems a good solution to my pc (it's the same machine)

I've downloaded the files but when I started to apply the first patch i've got this message

390_LinuxSTA_V2.4.0.4_WiFiBTCombo_DPO$ patch -p0 < rt5390sta-2.4.0.4-config.patch
patching file Makefile
Reversed (or previously applied) patch detected! Assume -R? [n]

I tried to type "n" but the answer was

[Reversed (or previously applied) patch detected! Assume -R? [n] n
Apply anyway? [n] y

Hunk #2 FAILED at 333.

so, what I have to do?
