Somebody in the thread at some point said:
I tried this - and the driver did load but is highly unstable in my
machine.
As soon as it fired up it loaded the driver when I plugged in the USB
dongle, and managed to get an IP address via dhclient OK, but looking
at iwconfig it showed a speed of 1Mb/s listed.
Very soon after that the link dropped out, and got a lot of messages with:
kernel: phy0 -> rt2x00usb_vendor_request: Error - Vendor Request 0x07 failed
for offset 0x308c with error -110
Gah fatal machine instability only makes you stronger ;-)
Personally I would install a development kernel at that point
yum --enablerepo development update kernel
because they have much later wifi stuff in them than the FC6 kernels.
