I tried that, but I happen to live in a brick house that was apparently constructed to be tank-proof: if I set my radio to 10 mw, I lose all signal on the other side of one wall.
Still, we are planning our move to a sunnier part of the world (Thailand) and the house we're building over there is going to be a lot more WiFi-friendly. So I'll keep your advice stored for later use, okay?
I was always under the impression that the radio stays powered when in online mode (but not necessarily online), but that the 770 lets the connection timeout to conserve *some* power. I could be totally wrong though.
The manual is a little ambiguous. But when connecting the 770 for VNC, if I haven't made a WiFi connection, or if I haven't used the browser for a few minutes, VNC will tell me that it is unable to make the connection. I took that to mean the 770 switches off WiFi after x amount of minutes.
I remember someone saying they tried continuous ping requests, at four seconds they got replies, at 5 they got timeouts. (This was with *no* other network activity). Looks like it's pretty aggressive power saving.
The bars are really unreliable for battery - like on cell phones - you could get half the bars and then you reboot it and it could complain about battery.
Thanks to Hedge for the 10 mW tip, should make a bit of a difference, I would not have thought you can change such settings with the provided GUI.
