Time Capsule Settings - Power and Country Variations

[wifibilly]

Hi everyone,

Few questions on power output and wifi strength for the new TC (or AirPort Extreme):

1. On Apple's web site they state that it supports 32.5 dBm (varies by country). Does anyone have a list of those countries and corresponding power outputs ?

2. Can the dBm be altered using the "Country" option in the Aport Utility; I noticed there is an option there, what does changing the country do exactly?

3. Is there a way to force the TC to only use 802.11 a/b or g only ... or is it always supporting all versions at all times?

4. Any way to reduce the power output / signal strength through some SSH hack, or other method? I would like to weaken the power to at least 50% of what it is now; short of cracking it open and pulling out the antenna, hope there is an alternative

Thank you - appreciate any help or feedback !

3. alt-click the list of options, it will give you more than are normally there.

hi waw74,

Thanks for the reply ... will this change the power output/strength of the TC, or just the version of supported speed?

Be careful, as changing the country may also change the frequency/power combinations used, and you may find yourself transmitting in a frequency range or at a power level that is reserved for something else in your country, thus bringing an eventual knock on your door if something gets interfered with.

hi all,

thanks for the feedback ... so i just noticed that in the new version of AirPort Utility there are many missing features (e.g. transmit power, interference robustness, multicast rate etc.) ... how do I get all those features back with the new TC? That way I can at least control the output power, a/b/g/n/ac settings etc. - see the 2009 manual below of the older version with a whole bunch of options i cannot see in the new version ...

in the meantime, does anyone know what changing the country does ? technically speaking ...
