    Re: Cannot connect the wireless adaptor in ubuntu 10.04

    HI1, dilantha,
    Which adapter do you have ? and what driver is it using ?? [ What does 'Network Connections' show? Network Icon Menu.]

    The Ralink [148f:3070] could be the R2070 or R2080 or several others .

    Please Post
    Code:
    sudo lshw -C network
    rfkill list all
    lsmod | grep -ie r2 -ie rt2
    'lshw' should show which driver is in use, 'lsmod' the module available { if it does not try adding '-ie r'.

    Chao!, bogan.
