RE: [pfSense Support] Output (mwatt) of a minipci wireless card
My view is that wireless can be considered in the same way The Net it. Unsafe. Howver generally people on it are uninterested in the data passing across it just because of sheer volume. If you have data that is sensitive or you just don't want people to view it use tunneling, that's what Ipsec and PPTP were invented for. i.e. leave your APs open and tunnel into your own network. My view is that lowering tx and using directional antennas is a courtesy thing. If you spend time thinking about your design you get better performance because you have less noise.

RE: [pfSense Support] Output (mwatt) of a minipci wireless card
I agree with you 100%. If you have sensitive data then yet it should either be going over a wired connection or a secure tunnel/vpn when going over a wireless connection. My point was that adjusting the TX power does serve a purpose though. In many situtation were you want to try to prevent your signal from being broadcast farther than the needed. Not even for any security reasons but to try to prevent APs from causing noise onto each others channel.

RE: [pfSense Support] Output (mwatt) of a minipci wireless card
The reson for me is that there is only 100mW (as a maximum) legal here. When i would use 400mW i could get a fine for it. But when i use lets say 200mW the chance i get a fine is not that big.

RE: [pfSense Support] Output (mwatt) of a minipci wireless card
HI In my experience its not always about mw transmitted. Using a proper antenna and a radio with decent receive sensitivity usually gets the job done better and you don't interfere and piss off your neighbours(who call the authorities to give you a fine, because you are polluting the band). Shouting the loudest doesn't always work(unless you are going for distance, in which case you would use 2x 400mw and very directional antennas) Remember also that the devices you are going to be connecting to will also have to transmit at 400mw in order for you to establish a connection. Most devices transmit at 100mw .. so you will see the ap but you will never be able to associate.
