Hard to say if there is a difference. I've noticed that signal quality changes between reboots. When I first tried this patch I couldn't get above 36M even at the AP, so I loaded the version without the patch. Same thing. So I rebooted and then all rates worked, even 11M. Even for the driver version that didn't work a few days ago. New/updated observations: Rate scaling seems to work, but if it gets down to 1M it will not rise again unless I force it to a higher bitrate and run iperf for a few seconds before setting it to auto. This is even when signal is -5dBm and noise is -80dBm. I get a feeling it's a bit to sensitive as it will drop quickly at a few meters away. At this distance forced 54M still works well. Maybe this is due to small dips (0.5sec) in traffic flow?! With the patch applied power is reported as 27dB in debugfs. With debug_xmitpower dmesg reports desired power to be 16.5 and actual 16.25. This is max when I manually set power through debugfs. After a while it's down to 10dB, even though only 1M works where I sit. Range seems to be higher for B-rates. Maybe this is just how things are, I lack experience. _______________________________________________ Bcm43xx-dev mailing list Bcm43xx-dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/bcm43xx-dev
