Well, I also could have sworn that my battery life got better after switching to 10mw, but maybe it was just too positive thinking. Still, maybe I should test a little bit more between these two settings. At least it radiates then a bit less, so my hairy green glowing hands won't get any hairier or greener!

According to manual 770 is compatible with 802.11b and 802.11g, so presumingly it uses 802.11g when it can. I don't need the additional speed that 11g provides, but would rather use 802.11b for lower power consumption. Disabling it from the router is no option, because I need G for my laptop. Has anyone any insights how to disable 802.11g in 770?
