Subject: Re: Ralink RT5592 5Ghz capability not working

Hello, thanks for your answer. I'm completely sure the hardware supports 5Ghz:
with the proprietary ralink driver it works. As you can see from the dmesg,
the board actually has a RT5592, not a RT3091. So I think the board has only
the pci device id of the RT3091, and that is confusing the rt2800pci driver,
making it assume it is a 2.4GHz device.

What do you think? Thanks
