This is usually because the driver you've got has bugs or isn't
correctly implemented.  Which is why we recommend drivers from the
kernel since out-of-kernel drivers are known to have quality problems.
One quick check here is to open up a terminal and "cd
-P /sys/class/net/ra0" and then type "ls".  Do you see a 'device' link
in the returned list?  It should look something like this:

lrwxrwxrwx 1 root root    0 2010-03-15 16:02 device -> ../../../0000:02:00.0

If not, the driver is buggy.  Next, do "cd -P device" and do another
"ls".  You should see a 'driver' link there.  It'll look something like
this:

lrwxrwxrwx 1 root root    0 2010-03-15 12:32 driver -> ../../../../bus/pci/drivers/iwlagn

Then "cd -P driver", and run "pwd".  If you don't get something like
"/sys/bus/pci/drivers/iwlagn" (of course you'll have the ralink driver
name, not 'iwlagn') then the driver is also buggy.
