Problem with ALFA Awus051NH

[Sentello]

Hi friends, I have Alfa AWUS051NH and LinuxMint9 (Ubuntu 10.04).
I got the latest compact wireless drivers from Jano http://forum.aircrack-ng.org/index.php?topic=5755.0 (driver-patch/compat-wireless-aircrack-lucid-patched.tar.bz2).

But I have serious problem, my AWUS051NH don't see any 5Ghz wifi!
With driver rt2800usb working everything:

iwlist wlan0 chanel
wlan1 27 channels in total; available frequencies :
Channel 01 : 2.412 GHz
Channel 02 : 2.417 GHz
Channel 03 : 2.422 GHz
Channel 04 : 2.427 GHz
Channel 05 : 2.432 GHz
Channel 06 : 2.437 GHz
Channel 07 : 2.442 GHz
Channel 08 : 2.447 GHz
Channel 09 : 2.452 GHz
Channel 10 : 2.457 GHz
Channel 11 : 2.462 GHz
Channel 12 : 2.467 GHz
Channel 13 : 2.472 GHz
Channel 14 : 2.484 GHz
Channel 36 : 5.18 GHz
Channel 38 : 5.19 GHz
Channel 40 : 5.2 GHz
Channel 44 : 5.22 GHz
Channel 46 : 5.23 GHz
Channel 48 : 5.24 GHz
Channel 149 : 5.745 GHz
Channel 151 : 5.755 GHz
Channel 153 : 5.765 GHz
Channel 157 : 5.785 GHz
Channel 159 : 5.795 GHz
Channel 161 : 5.805 GHz
Channel 165 : 5.825 GHz
Current Frequency:2.457 GHz (Channel 10)

But with rt2780sta working only 2.4 Ghz (11 channels!!!) It's very strange.



switch from rt2800usb to rt2870sta:
sudo ifconfig wlan0 down
sudo modprobe rt2800usb
sudo rmmod rt2870sta

iwlist wlan0 channel
wlan0 11 channels in total; available frequencies :
Channel 01 : 2.412 GHz
Channel 02 : 2.417 GHz
Channel 03 : 2.422 GHz
Channel 04 : 2.427 GHz
Channel 05 : 2.432 GHz
Channel 06 : 2.437 GHz
Channel 07 : 2.442 GHz
Channel 08 : 2.447 GHz
Channel 09 : 2.452 GHz
Channel 10 : 2.457 GHz
Channel 11 : 2.462 GHz
Current Frequency:2.457 GHz (Channel 10)

I need 5Ghz frequency for surfing...
Can you help me? ](*,)
