I have a Siemens SX551 WLAN dsl - Wifi router - (in The Netherlands called the 'KPN Experia box') and I am able to setup it's sending power. Now I wonder, what would be the best option to set this up? Example: I want to beam as less waves as possible, so I put it in '802.11G' mode only. I really hate it when my network is available in the whole village (just like I can see all my neighbours' networks now) - and I'm not talking about hiding SSID etc, but really reducing the power up to what I need. The question: But does my macbook work like GSM works if the connection isn't that great? E.g. will my macbook start sending more power? Or is this option reserved to the accesspoints? Is there a software program so I can see how much power my macbook emits (iStumbler only lets me see how much the router emits).
