rt2800pci + 3.6.x = not working (Linksys WMP600N)

Hi, just a report...

I have Linksys WMP600N (dual-band) wireless card,

06:05.0 Network controller [0280]: RaLink RT2800 802.11n PCI [1814:0601]
Subsystem: Linksys Device [1737:0067]
Kernel driver in use: rt2800pci
Kernel modules: rt2800pci

It is working in 3.5.x but not in 3.6.x. It doesn't connect and get IP (dhcp) from the router. Also, this wireless card works reliably only in 3.5.x. Previous versions tend to drop connections.
