Can't connect to encrypted networks

[MartinT01]

I would appreciate any help. I am new to linux and have spend the last couple of days tearing my hair out on this problem.

Firstly I have an EEE 901 dual-booting Backtrack 4 final (with persistent changes)
Network card : RaLink RT2860

Problem : I can't connect to my home network with encryption turned on. If change my network to unencrypted it works fine so I assume the network card is setup ok. I also know this is not a hardware problem as it works fine on same machine under Crunch Bang which I also believe is ubuntu based.

I have tried
WICD first....failed to authenticate : either with psk as asci or hex
several other network manager programs (all have now been removed)

I am now using WPA_SUPPLICANT from the command line. I have followed numerous guides to creating wpa_supplicant.conf. I've tried just the ssid and psk in asci or in hex....no luck

Current wpa_supplicant.conf

ctrl_interface=/var/run/wpa_supplicant
eapol_version=1
#ap_scan=1
network={
	ssid="PlusnetWireless"
	scan_ssid=1
	proto=RSN
	pairwise=CCMP TKIP
	key_mgmt=WPA-PSK
	psk=SOME_PASSWORD	
}

I tried every setting I can come across for this and everytime I get.....

#wpa_supplicant -Dwext -i ra0 -c/ect/wpa_supplicant.conf
ioctl[SIOCGIWSCAN] : Resource temporarily unavailable
CTRL-EVENT-SCAN-RESULTS
Trying to associate with <ROUTER MAC ADDRESS> (SSID='PlusnetWireless' freq=2412 Mhz)
Authentication with <ROUTER MAC ADDRESS> timed out

this keeps looping around until I hit ctrl+c when I get

^CCTRL-EVENT-TERMINATING - signal 2 received

iwlist ra0 scan suggests

..
IE: IEEE 802.11i/WPA2 Version 1
Group Cipher : CCMP
Pairwise Ciphers (1) : CCMP
Authentication Suites (1) : PSK

Some other info...

#airmon-ng start ra0
Found one process that could cause trouble.....................
PID xxxxx dhclient (running on ra0)

Interface = ra0
Chipset = RaLink 2560 PCI
Driver = rt2500 (monitor mode enabled)

also

airodump-ng ra0 shows my network with following attributes

ENC=WPA2
CIPHER=CCMP
AUTH=PSK

however, a windows server 2008r2 machine reports
Security type : WPA2-Personal
Encryption Type : AES

I have read CCMP is part of AES so is this effectively saying the same thing


Really sorry for such a long first post. I appreciate there alot of similar posts but I have read the ones I have come across, tried what was suggested and had no luck. Hope it all makes sense as very tired at the minute. Just want to get this working. I would appreciate any suggestions, whatever they may be.

Many thanks once again

Man, try to use the wicd, with the ndiswrapper driver.
I already had a RaLink card, and I could use it very well with the ndiswrapper.

Bye.
