Now it's about 2.5 MB/s. 64 is not a safe value in this case and rt2800usb_txdone_entry_check tries to protect against a special case where the tx status for single frames gets "lost". But at least we now know a little more about this issue. > But still there is still room for improvement. :) > Looks like rt2800usb_txdone_entry_check was the major cause for the delay. Ok, thanks for trying. I'll think about a proper solution without causing regressions ... Helmut
