Was talking just about changing/tuning values of some registers to increase reception sensitivity. The people of linux, seem to have increased the sensitivity by modifing bbp17 and disabling autotuning. I tried with bbp17 and for the autotuning disabled, well, we already have it implemented :) (just joking) Anyway, giving that I didn't get an increase of sensitivity, I think we'll need the help of the developers. Well, this morning will try to increase sensitivity of those usb rum with a linux system, just to check what they say here : http://209.85.229.132/search?q=cache:H8W6R5Ds3mYJ:forum.aircrack-ng.org/index.php%3Ftopic%3D2235.0+bbp17+ralink+linux&cd=1&hl=ca&ct=clnk&gl=es&client=firefox-a Regards, Gus
