First ensure the interface is up
then check that your card see the outer space (networks in range)Code:ifconfig ra0 up
If you see one or more AP there, then everything is working.Code:iwlist ra0 scan
Now you may
1.- Use wicd to connect to your network
2.- Use console commands. Do not use "iwconfig". Use instead "iwpriv" command for rt2860
All the info about how to setup wicd and iwpriv is here in the forum.
Yes, it is possible to remove kde and install gnome and there is a post about it. But you need to know what you are doing. Just dont do it.
Good luck
