    I have not loaded your firmware as yet but could you tell me does your firmware allow transmision levels adjusted or are they set at 42 and cannot be adjusted.

    They are set at 42mW but will be adjustable in the future.
    Below is the reason why I choice 42mW and not 84mW :

    Why 42mW Xmit Power and not 84mW?
    - It's more than enough for most people, it's even the double of that used in the original v2.02.7 firmware from Linksys.
    - It's safe to use without extra cooling.
    - It's legal to use in most countries.
    - Any value above 56mW will make the signal dirty, which results in packet loss and interference on the other channels.

    in sveasofts forums there has been a few discussions on the power transmission levels and someone actaully used a spectrum analyser. sveasofts firmware allows settings of upto 251 mw most people there use 84 afaik.

    personally i think you should have default, 42 56 70 and 84 perhaps

    unless you allow like sveasoft to enter you own numbers. 0-84

    Unfortunatly I can't access the sveasoft forums, but their spectrum analyser test will probably say the same as this one :;10932182

    However I will most likely make an option to control from 0-84mW.
    I will not go to 251mW, because settings higher then 84mW will probably burn out or seriously damage the radio portion of your router in time.

    If you still want a better range, just buy some $5 higher gain antenna's, they will keep the signal clear and the performance high.

    If and when you do add adjustable transmission power, may I suggest you include a kind of understandable scale for novices to use? Simply having discreet values (such as Default, 42, 56 70 and 84mW) to choose from can be totally meaningless, since the user may not know how one value relates to other values in the selection.

    For example, with the WiFi-Box firmware, he attaches percentages to the unit of measurement so people can see the default is at 25% of full power, and each discreet step available for selection is a percentage of full power: 50%, 65%, 75%, 100%, easy to understand what each setting represents in term of increased power.
