Exactly my experience here, especially the USB ones (but seems to be
heavily hardware dependent). And they produce enormous cpu load as soon
as throughput rises.

That's why I'm only using the vendor driver (for STA), too (besides the
point that rt2800usb doesn't support a Linksys AE3000 at all e.g.
(http://wikidevi.com/wiki/Linksys_AE3000), which is a really fine device!)

It would be cool on the one hand, if Mediatek would integrate their own
drivers themselves to mac80211, but on the other hand, I fear, this is
mostly impossible because mac80211 (which was heavily built for and from
Atheros and Intel and therefore "optimized" for there own needs) doesn't
match the requirements of the Ralink hardware.

That's why I'm happy they don't integrate their drivers in the existing
mac80211 because I fear a likewise bad quality.


I think the maintainer of rt2800 do all they can given the opportunities
they have so far. Unfortunately, they have very little opportunities
from my point of view.



Kind regards,
