In prior versions of tomatousb firmware, the default value for transmit power was 42. Now it appears somewhere along the line it got changed to 17. With dd-wrt, the default setting is also 17, but apparently this is for 17dBi and not 17mw, so in actuality it's 50mw.
I have been using a value of 100 to get higher range, does this mean in the later versions I am now setting 100dBi (!) as my transmit power? Would a proper transmit power setting be a value of 20 (dBi) for 100mw?
