I'm using Satori-4.0 v2.07.1.7sv on a WRT54G v2.0. I went to advanced wireless settings and upped the transmit power from 28 mw to 29. Now I'm wondering, approximately how much more range will I get for each mw of increase? I don't need precision, just some ballpark numbers. I understand that obstructions are going to cut my range way down. Thanks a lot!
