    Okay tightened all the aerials in the back of the card & did a scan.

    Managed to pickup a very weak signal for the WEP wifi network I want to connect to.

    But when I try to connect it just spins out, never manages it.

    Not sure why the signal is so low or why it can only pickup one network

    Let's try:
    Code:
    sudo iwconfig ra0 power on
    sudo iwconfig ra0 txpower 10
    If 10 errors, try 9, 8, etc. until it sticks. If it doesn't error, try 11, 12, etc. Then scan and try to connect again.

    works out of the box for me..

    speaking of which

    does anyone know if full wireless N support is on the way?

    Ralink's website states the Linux driver has wireless N support yet I am only connecting at G speeds

    Let's take another look:
    Code:
    sudo iwpriv ra0
    Thanks.

    First, be sure you have build-essential and linux-headers-generic installed. Synaptic is your friend. Then open a terminal and do, each command separately and in order:
    Code:
    lspci -v
    sudo lshw -C network
    Please verify you have a rt2860 device. If so, please proceed, if not, post back and tell us what you really have. Now do:
    Code:
    wget http://www.ralinktech.com.tw/data/drivers/2008_0522_RT2860_Linux_STA_v1.6.1.0.tar.bz2
    tar -xvzf 2008_0522_RT2860_Linux_STA_v1.6.1.0.tar.bz2
    cd 2008_0522_RT2860_Linux_STA_v1.6.1.0
    sudo su
    If your card will connect using WPA, we will have some adjustments to make:
    Code:
    gedit os/linux/config.mk
    In line 11, change HAS_WPA_SUPPLICANT=n to HAS_WPA_SUPPLICANT=y; in line 14, change HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=n to HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y. Proofread, save and close. Now, do:
    Code:
    make
    cp RT2860STA.dat /etc/Wireless/RT2870STA/RT2870STA.dat
    make install
    modprobe rt2860sta
    Does your device wink, blink and spring to life? Can you connect?

    I've just downloaded the latest drivers (1.8.0.0) from the Edimax website, and followed your instructions up the the [make] command. I'm getting the following output:

    make: *** [LINUX] Error 2

    I'm running 10.04 (Lucid). I have the build-essential (11.4 build 1) and linux-headers-generic packages installed.

    When I did [sudo iwconfig wlan0 power on] I got the following:
    Error for wireless request "Set Power Management" (8B2D) :
    GET failed on device wlan0 ; Network is down.

    If I run [lspci -v] I get:
    01:07.0 Network controller: RaLink RT2800 802.11n PCI
    Subsystem: Edimax Computer Co. Device 7728
    Flags: bus master, slow devsel, latency 64, IRQ 19
    Memory at dffb0000 (32-bit, non-prefetchable) [size=64K]
    Capabilities: <access denied>
    Kernel driver in use: rt2860
    Kernel modules: rt2860sta

    Why the <access denied>?

    Where am I going wrong?
