How much did your connection slow down? Enough to notice it when connecting through a 3MBit Adsl connection i.e. with the patch i get 30 40 60 ... 80 kiB maximum without it full 310 KiB so it is an issue for me (i have inet <-> modem-router <-> myPC only so i can not test with another pc) > It is clear that this > commit might possibly slow down your connection, but not by a lot. Well it does by a lot avg of 60 KiB vs 300 KiB is lot for me And that's only because before we were sending with a higher rate than the > AP allowed us to...

My Ap is set to "mixed" but i connect at G speeds ie iwconfig show 54M or 48M or 36M but the connection is slow nonetheless Do you think that would make such a difference (the ap mode)?

Could be that rt2x00 is doing something wrong with that "rate bitmap" ?? I'm not programmer so i can not check myself > > johannes Alejandro Thanks for the response...
