I am seeing poor performance on my WiFi that seems to have deteriorated since FreeBSD V11.0. I see an average of about 35 errors for every packet transmitted. wlan0 1500 <Link#3> a0:88:b4:c6:ad:28 14501195 0 0 367667 12886354 0 I have always seen lot of errors on transmission on this interface, but I have recently noticed that uploads were very slow. They seem to max out at about 20 Mbps (bits, not bytes). For "normal" traffic (as opposed to test traffic) it is often much worse, often topping out at around 2 or 3 Mbps. No input errors at all and god download performance. Are others seeing this? Any suggestions for troubleshooting? I don't see much in the way of statistics or diagnostic information on iwn. the man page gives me no clues.
