I meant throughput. Yeah, well. There's no actual medium (access) simulation in hwsim, so the actual throughput you get only depends on the performance of your CPU. 33Mbps seems quite low, but of course I don't know where you're running this. Then again, you say you're using wmediumd, so perhaps that *does* have some sort of medium simulation these days? I didn't think it has it but I may very well be wrong on that. Try pure hwsim (no wmediumd) and see if you get gigabits, if not then your system is probably just too slow. And then I guess you'd have to look at wmediumd in more detail to see if it has some simulations here? I don't know. johannes
