I have the same problems described in the description with my rt2500, I use an unsecured network and network-manager sees my ESSID but can't connect.
To get my wireless working I had to
sudo ifdown ra0 sudo nano /etc/network/interfaces -type in my network info on ra0 sudo ifup ra0
No everytime I reboot I just need to do a simple "sudo ifdown ra0" and "sudo ifupra0", my wireless then works but network-manager is still unusable.
