 ===== With maximum output power, I'll get a better range  ===== ===== With maximum output power, I'll get a better range  =====
-It's false in most situations.\\ + 
-As an advice, in a home environment, the best output power is not everytime the maximum. In most situations, 30mw is enough.\\ +This is a false assumption in most situations. 
-If you're doing long links, yes, maximum output power is the best.+ 
 +In a home environment, the best output power is not always the maximum. In most situations, 30mw is enough.  However, if you are a long distance from the AP, then yes, maximum output power is the best.

 ===== I'll buy amplifiers to have a better range  ===== ===== I'll buy amplifiers to have a better range  =====
-That's not a very good idea because:  
  
-  - Amplifier also amplify noise and that's not a good thing for link quality  +That is not a very good idea because:  
-  - With high amplifications, you could get headache + 
 +  - Amplifiers also amplify noise and that's not a good thing for link quality  
 +  - With high amplifications, you could get a headache

 +You are much better off purchasing a good antenna with high gain.
  
-Then you should better buy good antenna's 
  
 ===== My card says that I have 20dBm (100mW) but i only have 18dBm, why?  ===== ===== My card says that I have 20dBm (100mW) but i only have 18dBm, why?  =====
-Most cards have 100mW, but with the antenna (2dBi antenna).+ 
 +Most cards have 100mW when combined with the antenna (2dBi antenna). 
 In 802.11a and 802.11g, the output power is 30mW due to modulation (it's a bit harder to use [[http://en.wikipedia.org/wiki/OFDM|OFDM]] than [[http://en.wikipedia.org/wiki/CCK|CCK]])  In 802.11a and 802.11g, the output power is 30mW due to modulation (it's a bit harder to use [[http://en.wikipedia.org/wiki/OFDM|OFDM]] than [[http://en.wikipedia.org/wiki/CCK|CCK]]) 
  
-===== With a better txpower, i have receive better  ===== + 
-That's false, txpower isn't linked with receiving at all. For receiving, you should see receive sensivity of your card +===== With better txpower, I will have better reception  ===== 
 + 
 +That's false, txpower isn't linked with receiving at all.  For receiving, you should see receive sensitivity of your card.  As well, you are much better off purchasing a good antenna with high gain.
